                               PROSPECTUS SUMMARY

The  following  summary is  qualified  in its  entirety by reference to the more
detailed  information and consolidated  financial statements appearing elsewhere
and incorporated by reference in this Prospectus.


                                   THE COMPANY

         Alfacell    Corporation    ("Alfacell"   or   the   "Company")   is   a
biopharmaceutical  company  organized  in  1981  to  engage  in  the  discovery,
investigation  and development of a new class of anti-cancer drugs isolated from
leopard  frog  eggs  and  early  embryos.  The  Company's  first  product  under
development is ONCONASE(R)  which targets solid tumors,  most of which are known
to be resistant to other  chemotherapeutic  drugs. To date, the most significant
clinical results with ONCONASE have been observed in pancreatic,  non-small cell
lung, mesothelioma and metastatic breast cancer.

   
         The Selling Stockholders acquired  substantially all of the outstanding
shares of Common Stock offered hereby and the Warrants directly from the Company
in private  placement  transactions  which were completed on March 21, 1994 (the
"March 1994 Private Placement"), September 13, 1994 (the "September 1994 Private
Placement"), October 21, 1994 (the "October 1994 Private Placement"),  September
29, 1995 (the "September  1995 Private  Placement"),  several private  placement
transactions  during the period of  October  1995 to April 1996 (the  "1995/1996
Private  Placements"),  in a private placement transaction completed on June 11,
1996 (the "June 1996  Private  Placement"),  in  connection  with a raw material
purchasing  agreement  dated October 5, 1995 (the "Supply  Agreement")  and in a
private  placement  made on March 3, 1997 (the "March 1997  Private  Placement")
(the  investors  in the March 1994  Private  Placement,  September  1994 Private
Placement, October 1994 Private Placement, September 1995 Private Placement, the
1995/1996  Private  Placements,  the June 1996  Private  Placement,  the  Supply
Agreement  and  the  March  1997  Private   Placement  are  referred  to  herein
collectively as the "Private Placement Investors").  See "Selling Stockholders."
134,834 of the  outstanding  shares of Common Stock offered hereby were acquired
pursuant to the  exercise of  previously  outstanding  options  (the  "Exercised
Options").  The Company  will not receive any of the  proceeds  from the sale of
Common Stock by the Selling Stockholders. To the extent any Warrants, Options or
the Bank Warrant are exercised,  the Company will apply the proceeds  thereof to
its general  corporate  purposes.  See "Use of Proceeds." The March 1994 Private
Placement,  the  September  1994  Private  Placement,  the October  1994 Private
Placement,   the  September  1995  Private  Placement,   the  1995/1996  Private
Placements, the June 1996 Private Placement, the Supply Agreement and March 1997
Private Placement are sometimes  collectively referred to herein as the "Private
Placements".  The Option Holders  acquired the Options directly from the Company
in private  transactions  during the period from October  1992  through  January
1993.  The bank  acquired the Bank Warrant from the Company in October,  1995 in
connection  with the  amendment  to the term loan  agreement  (the "Term  Loan")
between the Company and the bank.
    

         Alfacell,  a  Delaware  corporation,  was  incorporated  in  1981.  The
Company's  executive offices are located at 225 Belleville  Avenue,  Bloomfield,
New Jersey 07003, telephone (973) 748-8082.


                                  The Offering

          This Prospectus relates to an offering by the Selling  Stockholders of
               up to 4,232,577  shares of Common Stock of the Company.  Of these
               shares  (i) an  aggregate  of  2,936,010  shares of Common  Stock
               (including 6,060 shares issued pursuant to the Supply  Agreement)

               Placement  Investors  either directly in the Private  Placements,
               pursuant  to the  exercise  of  Warrants  issued  in the  Private
               Placements,   or  pursuant  to  the  Exercised  Options  (ii)  an
               aggregate of 698,251
    

                                      - 2 -

<PAGE>


   
               shares may be issued  upon  exercise of the  Warrants  which were
               issued  to  the  Private  Placement   Investors  in  the  Private
               Placements,  (iii) an aggregate  of 588,316  shares may be issued
               upon  exercise  of the  Options  which were  issued to the Option
               Holders in certain  other  private  transactions  and (iv) 10,000
               shares may be issued to the  Company's  bank upon exercise of the
               Bank Warrant issued in connection  with the Term Loan  amendment.
               See "Selling Stockholders."
    

Securities Outstanding..

   
          As   of September 5, 1997, the Company had 14,847,493 shares of Common
               Stock outstanding. Assuming that all of the Warrants, the Options
               and the Bank Warrant are  exercised and no other shares of Common
               Stock are issued  subsequent  to September  5, 1997,  the Company
               would have 16,009,226 shares of Common Stock outstanding.
    

Use of Proceeds........

   
          The  Company will not receive any proceeds from the sale of the shares
               of Common Stock  offered by the Selling  Stockholders.  If all of
               the Warrants, the Options and the Bank Warrant are exercised, the
               Company will receive  estimated net proceeds of  $5,877,106.  The
               Company  intends  to  utilize  any  proceeds  received  from  the
               exercise of the  Warrants,  the Options and the Bank  Warrant for
               general corporate purposes, including the funding of research and
               development activities. There can be no assurance that any of the
               Warrants, the Options or the Bank Warrant will be exercised.  See
               "Use of Proceeds."
    

Risk Factors.............

          See  "Risk  Factors"  for a  discussion  of certain  risk factors that
               should be considered by prospective  investors in connection with

or future plans.  No assurance can be given that the future  results  covered by
the forward-looking  statements will be achieved.  The following matters include
cautionary  statements,  including certain risks and  uncertainties,  that could
cause actual results to vary  materially from the future results covered in such
forward-looking  statements.  Other factors  could also cause actual  results to
vary  materially  from  the  future  results  covered  in  such  forward-looking
statements.

   
         Development  Stage  Company,   Significant   Accumulated  Deficit,  and
Uncertainty of Future Profitability.  The Company is a development stage company
which is  subject  to all of the  risks  and  uncertainties  of such a  company,
including  uncertainties  of product  development,  constraints on financial and
personnel resources and dependence upon and need for third party financing.  The
Company's  profitability  will depend  primarily upon its success in developing,
obtaining regulatory approvals for, and effectively marketing ONCONASE. ONCONASE
has not been approved by the United States Food and Drug Administration ("FDA").
Potential  investors  should be aware of the  difficulties  a development  stage
enterprise  encounters,  especially  in view of the intense  competition  in the
pharmaceutical industry in which the Company competes. There can be no assurance
that the Company's plans will either  materialize or prove successful,  that its
products under development will be successfully  developed or that such products
will generate revenues sufficient to enable the Company to earn a profit.  Since
the  Company's  incorporation  in 1981,  a  significant  source  of cash for the
Company has been public and private  placements of its  securities.  At July 31,
1996, and April 30, 1997,  respectively,  the Company had an accumulated deficit
of  approximately  $40,400,000,  and  $43,400,000,   respectively.  The  Company
anticipates that it will continue to incur substantial losses in the future. The
Company is pursuing licensing,  marketing and development  arrangements that may
result in contract  revenue to the Company prior to its receiving  revenues from
commercial  sales of  ONCONASE.  To date,  the Company has not received any such
revenues.  There  can  be  no  assurance  that  the  Company  will  be  able  to
successfully consummate any such arrangements.
    

         No Assurance Of Successful  Product  Development Or  Commercialization;
Uncertainties Related To Clinical Trials. The Company's research and development
programs are at various  stages of  development,  ranging  from the  preclinical
stage  to  Phase  III  clinical  trials.  Substantial  additional  research  and
development  will be  necessary  in order for the  Company to develop and obtain
regulatory  approval for its product  candidates,  and there can be no assurance
that the Company's research and development will lead to development of products
that  are  shown  to be safe  and  effective  in  clinical  trials  and that are
commercially  viable.  In  addition to further  research  and  development,  the
Company's product candidates will require clinical testing,  regulatory approval
and  development  of  marketing  and  distribution  channels,  all of which  are
expected   to   require    substantial    additional    investment    prior   to
commercialization. There can be no assurance that the Company's products will be
successfully  developed,  prove to be safe and  efficacious in clinical  trials,
meet applicable regulatory  standards,  receive marketing approval from the FDA,
be capable of being produced in commercial  quantities at acceptable  costs,  be
eligible for third party reimbursement from governmental or private insurers, be
successfully  marketed or achieve  market  acceptance.  Further,  the  Company's
products  may prove to have  undesirable  or  unintended  side  effects that may
prevent or limit their commercial use.

         The Company may find,  at any stage of its  research  and  development,
that products  which appeared  promising in  preclinical  studies or Phase I and
Phase II clinical trials do not demonstrate  efficacy in larger-scale  Phase III
clinical  trials and do not  receive  regulatory  approvals.  The  results  from
preclinical testing and early clinical

                                      - 4 -

<PAGE>

trials may not be predictive of results  obtained in later  clinical  trials and
large-scale   testing.   Companies  in  the   pharmaceutical  and  biotechnology
industries  have  suffered  significant  setbacks in various  stages of clinical
trials,  even in  advanced  clinical  trials  after  promising  results had been
obtained  in  earlier  trials.  Accordingly,  any  product  development  program
undertaken  by the Company may be  curtailed,  redirected  or  eliminated at any
time. The rate of completion of the Company's  clinical trials may be delayed by
many factors,  including slower than anticipated patient enrollment,  or adverse
events occurring during the clinical trials.  Completion of testing, studies and
trials may take several years, and the length of time varies  substantially with
the type, complexity, novelty and intended use of the product. In addition, data
obtained from  preclinical  and clinical  activities are  susceptible to varying
interpretations, which could delay, limit or prevent regulatory approval. Delays
or rejections may be encountered  based upon many factors,  including changes in
regulatory policy during the period of product development.  No assurance can be
given  that  any of the  Company's  development  programs  will be  successfully
completed, or that the Company's products will receive FDA approval.

   
         Restrictions   Under   Secured   Financing.   As  of  August  31,  1997
approximately  $1,373,090 is owed to the bank pursuant to the Term Loan,  and is
secured by a lien on substantially  all of the Company's  assets,  including its
patents. The Term Loan agreement contains restrictive covenants which could make
it more  difficult to operate the Company's  business.  In the event the Company
defaults on the debt it owes to such bank,  the bank may foreclose on the assets
which  secure its debt and  utilize  such  assets to satisfy  such debt.  Upon a
liquidation  of the Company,  the Company's  assets would first be used to repay
its secured creditors and then its unsecured creditors,  before any distribution
would be made to holders of the Company's equity  securities.  Given the current
levels of the Company's assets and its  liabilities,  it is highly unlikely that
the  holders  of the  Company's  Common  Stock  would  receive  any  significant
distribution  in the event  the  Company  is  liquidated.  Pursuant  to a verbal
agreement between the Company and the bank for which  documentation is currently
being  prepared,  the balance of Term Loan will be due and payable in  December,
1997. At that time, the Company intends either to refinance the Term Loan or use
its current cash  resources or raise  sufficient  equity  capital to pay off the
unpaid  balance.  However,  there can be no assurance that the Company will have
sufficient cash resources  available at that time, that it will be able to raise
sufficient  equity  or that it will  be  able to  successfully  conclude  such a
financing.
    

         Need for, and  Uncertainty  of, Future  Financing.  The Company will be
required to expend significant funds on the further  development of ONCONASE and
its continued  operations will depend on its ability to raise  additional  funds
through equity or debt financings, collaborative agreements, strategic alliances
and revenues from the commercial sale of ONCONASE.  To date, the Company has had
several preliminary discussions regarding potential collaborative agreements and
strategic   alliances,   however  there  can  be  no  assurance  that  any  such
arrangements  will be  consummated.  Indeed,  there can be no assurance that any
such additional  funds will be available to the Company on acceptable  terms, if
at all.  The  Company  believes  that  its cash on  hand,  including  marketable
securities, as of April 30, 1997 will be sufficient to meet its anticipated cash
needs for approximately  the next two years assuming that a significant  portion
of such cash  reserves is not used to repay the Term Loan.  The Company  will be
required to raise additional funds to meet its cash needs upon exhaustion of its
current  cash  resources.  The Company  continues  to be  primarily  financed by
proceeds  from private  placements  of its Common Stock and  investments  in its
equity  securities.  If the  Company  is  unable  to  secure  sufficient  future
financing  may be  necessary  for the  Company  to curtail  or  discontinue  its
research and development activities.

         Government Regulation; No Assurance of FDA Approval. The pharmaceutical
industry in the United  States is subject to stringent  governmental  regulation
and the sale of ONCONASE for use in humans in the United States will require the
prior approval of the FDA. Similar approvals by comparable agencies are required
in most foreign  countries.  The FDA has  established  mandatory  procedures and
safety standards which apply to the clinical testing,  manufacture and marketing
of pharmaceutical  products.  Pharmaceutical  manufacturing  facilities are also
regulated by state,  local and other  authorities.  Obtaining FDA approval for a
new   therapeutic   drug  may  take  several   years  and  involve   substantial
expenditures.  ONCONASE has not been  approved for sale in the United  States or
elsewhere. There can be no assurance that the Company will be able to obtain FDA
approval for ONCONASE or any of its future products. Failure to obtain requisite
governmental approvals or failure to obtain approvals of the

                                      - 5 -

<PAGE>

scope  requested  will delay or preclude the Company from marketing its products
while under patent protection,  or limit the commercial use of the products, and
thereby  may have a  material  adverse  effect on the  Company's  liquidity  and
financial condition.  Further,  even if governmental  approval is obtained,  new
drugs are  subject to  continual  review  and a later  discovery  of  previously
unknown problems may result in restrictions on the particular product, including
withdrawal of such product from the market.

         Uncertain  Ability to Protect Patents and Proprietary  Technology.  The
Company  believes  it is  important  to develop new  technology  and improve its
existing technology. When appropriate,  the Company files patent applications to
protect such inventions. The Company owns five U.S. Patents: (i) U.S. Patent No.
4,888,172  issued in 1989,  which covers a  pharmaceutical  for treating  tumors
derived from fertilized eggs of a frog species;  (ii) U.S. Patent No.  5,559,212
issued in 1996  which  covers  the  amino  acid  composition  and  structure  of
ONCONASE; and (iii) U.S. Patents Nos. 5,529,775 and 5,540,925 issued in 1996 and
U.S. Patent  No.5,595,734  issued in 1997, which cover  combinations of ONCONASE
with certain  other  chemotherapeutics.  The Company  also owns U.S.  Patent No.
4,882,421, which has now been disclaimed and is therefore legally unenforceable.
This  disclaimer  permitted the Company to obtain U.S.  Patents Nos.  5,529,775,
5,540,925 and 5,559,212.  The Company owns two European patents.  These European
patents cover ONCONASE, process technology for making ONCONASE, and combinations
of ONCONASE  with certain other  chemotherapeutics.  The Company also owns other
patent applications,  which are pending in the United States, Europe, and Japan.
Additionally,  the Company owns an undivided  interest in an application that is
pending in the United States.  This application  relates to a Subject  Invention
(as that term is defined in cooperative  research and development  agreements to
which the Company and the National  Institutes of Health are  parties).  Patents
covering biotechnological inventions have an uncertain scope, and the Company is
subject to this uncertainty.  The Company's patent applications may not issue as
patents.  Moreover,  the  Company's  patents may not  provide  the Company  with
competitive  advantages  and may not withstand  challenges by others.  Likewise,
patents  owned by others may  adversely  affect the ability of the Company to do
business.  Furthermore,  others may independently develop similar products,  may
duplicate the  Company's  products,  and may design around  patents owned by the
Company.  The Company's patent  protection is limited to that afforded under the
claims of its  issued  patents,  unless and until  other  patent  protection  is
available to the Company.  Although  the Company  believes  that its patents and
patent  applications  are of substantial  value to the Company,  there can be no
assurance  that such patents will be of  substantial  commercial  benefit to the
Company,  will afford the Company adequate protection from competing products or
will not be challenged or declared invalid.  The Company expects that there will
continue to be  significant  litigation  in the industry  regarding  patents and
other  proprietary  rights and, if the Company  were to become  involved in such
litigation,  there  could  be no  assurance  that  the  Company  would  have the
resources  necessary to litigate the contested issues  effectively.  Pursuant to
the Term Loan  agreement  with the Company,  the  Company's  bank has a security
interest in the Company's patent  portfolio.  The bank has agreed,  however,  to
subordinate  its interest to licensees of the Company if certain  conditions are
met. The loss of the rights to the Company's  patents through the enforcement of
the  bank's  security  interest  could  have a  material  adverse  effect on the
Company.

         Intense Competition and Technological  Obsolescence.  There are several
companies,  universities,  research  teams  and  scientists,  both  private  and
government-sponsored,   which  engage  in  developing   products  for  the  same
indications  as the Company.  Many of these entities and  associations  have far
greater financial resources,  larger research staffs and more extensive physical
facilities than the Company.  Several  competitors are more experienced and have
substantially  greater  clinical,  marketing  and  regulatory  capabilities  and
managerial  resources than the Company.  Such  competitors  may succeed in their
research and  development  of products for the same  indications  as the Company
prior to the Company achieving any measure of success in its efforts.

         The  number of persons  skilled  in the  research  and  development  of
pharmaceutical  products is limited and significant  competition exists for such
individuals.  As  a  result  of  this  competition  and  the  Company's  limited
resources,  the Company may find it difficult to attract skilled  individuals to
research, develop and investigate anti- cancer drugs in the future.


                                      - 6 -

<PAGE>

         The business in which the Company is engaged is highly  competitive and
involves rapid changes in the  technologies  of discovering,  investigating  and
developing new drugs.  Rapid  technological  development by others may result in
the  Company's   products  becoming  obsolete  before  the  Company  recovers  a
significant portion of the research,  development and commercialization expenses
incurred with respect to those products. Competitors of the Company are numerous
and are expected to increase as new technologies become available. The Company's
success depends upon  developing and  maintaining a competitive  position in the
development of new drugs and technologies in its area of focus.  There can be no
assurance that, if attained,  the Company will be able to maintain a competitive
position in the pharmaceutical industry.

         Uncertain  Availability  Of  Health  Care  Reimbursement;  Health  Care
Reform.  The Company's  ability to  commercialize  its product  candidates  will
depend  in part on the  extent  to  which  reimbursement  for the  costs of such
product will be available from  government  health  administration  authorities,
private health  insurers and others.  Significant  uncertainty  exists as to the
reimbursement  status of newly approved  health care  products.  There can be no
assurance of the availability of adequate  third-party  insurance  reimbursement
coverage  that  enables the  Company to  establish  and  maintain  price  levels
sufficient  for  realization  of an  appropriate  return  on its  investment  in
developing   its  products.   Government  and  other   third-party   payors  are
increasingly  attempting to contain  health care costs by limiting both coverage
and the  level  of  reimbursement  for new  therapeutic  products  approved  for
marketing by the FDA and by refusing, in some cases, to provide any coverage for
uses of  approved  products  for disease  indications  for which the FDA has not
granted marketing  approval.  If adequate coverage and reimbursement  levels are
not provided by  government  and  third-party  payors for uses of the  Company's
product  candidates,  the market acceptance of these products would be adversely
affected.

         Health care reform  proposals  have been  introduced in Congress and in
various state  legislatures.  It is currently  uncertain whether any health care
reform  legislation  will be  enacted  at the  federal  level,  or what  actions
governmental  and private payors may take in response to the suggested  reforms.
The Company cannot  predict when any proposed  reforms will be  implemented,  if
ever, or the effect of any implemented reforms on the Company's business.  There
can be no  assurance  that any  implemented  reforms  will  not have a  material
adverse  effect on the  Company.  Such  reforms,  if  enacted,  may  affect  the
availability of third-party  reimbursement for products developed by the Company
as well as the price levels at which the Company is able to sell such  products.
In  addition,  if the  Company is able to  commercialize  products  in  overseas
markets, the Company's ability to achieve success in such markets may depend, in
part, on the health care financing and reimbursement policies of such countries.

         Potential Product  Liability.  The use of the Company's products during
testing or after regulatory approval entails an inherent risk of adverse effects
which  could  expose the  Company  to  product  liability  claims.  The  Company
maintains product liability insurance coverage in the total amount of $6,000,000
for claims arising from the use of its products in clinical  trials prior to FDA
approval.  There can be no  assurance  that the Company will be able to maintain
its existing  insurance  coverage or obtain coverage for the use of its products
in the future. Management believes that the Company maintains adequate insurance
coverage for the operation of its business at this time,  however,  there can be
no assurance that such insurance coverage and the resources of the Company would
be sufficient to satisfy any liability resulting from product liability claims.

   
         Dependence  Upon Key Personnel.  The Company is currently  managed by a
small number of key  management  and  operating  personnel,  whose  efforts will
largely determine the Company's success.  The loss of key management  personnel,
particularly Kuslima Shogen, the Company's Chairman and Chief Executive Officer,
would likely have a material  adverse  effect on the Company.  The bank may call
due all amounts  payable under the Term Loan  agreement  with the Company in the
event  Ms.  Shogen  ceases  for any  reason,  except  death,  to be a full  time
employee,  officer or director of the  Company.  The Company  carries key person
life  insurance on the life of Ms. Shogen with a face value of  $1,000,000.  The
Company's  bank has been assigned this policy as security for the  approximately
$1,373,090 outstanding under the Term Loan.

         Liquidity.  The Company's  Common Stock has been quoted on the National
Association of Securities  Dealers Inc.  Automated  Quotation System  ("NASDAQ")
Small Cap Market  since  December  5, 1996 and is  currently  thinly  traded.  A
limited trading market could result in an investor being unable to liquidate his
or her investment.

         No  Dividends.  The  Company has not paid any  dividends  on its Common
Stock since its  inception  and does not  currently  foresee the payment of cash
dividends  in the  future.  Furthermore,  under  the Term  Loan the  Company  is
prohibited  from paying any dividends  without the bank's  consent.  The Company
currently intends to retain all earnings, if any, to finance its operations.

         Preferred  Stock;   Anti-takeover  Device.  The  Company  is  currently
authorized to issue  1,000,000  shares of preferred  stock,  par value $.001 per
share.  The Company's Board of Directors is authorized,  without any approval of
the  stockholders,  to issue the preferred stock and determine the terms of such
preferred  stock.  There are no  shares  of  preferred  stock  outstanding.  The
authorized  and  unissued  shares of  preferred  stock may be  classified  as an
"anti-takeover"  measure and may discourage  attempted  takeovers of the Company
which are not  approved  by the Board of  Directors.  The  authorized  shares of
preferred stock will remain  available for general  corporate  purposes,  may be
privately placed and can be used to make a change in control of the Company more
difficult.  Under  certain  circumstances,  the Board of Directors  could create
impediments  to, or frustrate,  persons seeking to effect a takeover or transfer
in control of the  Company  by causing  such  shares to be issued to a holder or
holders who might side with the Board of  Directors  in opposing a takeover  bid
that the  Board of  Directors  determines  is not in the best  interests  of the
Company and its stockholders, but in which unaffiliated stockholders may wish to
participate.  Under  Delaware  law, the Board of Directors is permitted to use a
depositary  receipt  mechanism  which  enables  the Board to issue an  unlimited
number of fractional  interests in each of the authorized and unissued shares of
preferred  stock  without  stockholder  approval.  Consequently,  the  Board  of
Directors,  without further stockholder approval,  could issue authorized shares
of  preferred  stock or  fractional  interests  therein  with  rights that could
adversely  affect the rights of the holders of the  Company's  Common Stock to a
holder or holders  which,  when voted  together  with other  securities  held by
members of the Board of Directors and the executive officers and their families,
could  prevent  the  majority   stockholder   vote  required  by  the  Company's
certificate  of  incorporation  or  Delaware  law  to  effect  certain  matters.
Furthermore,  the existence of such  authorized  shares of preferred stock might
have the effect of discouraging any attempt by a person, through the acquisition
of a  substantial  number of shares of Common Stock,  to acquire  control of the
Company.  Accordingly,  the  accomplishment  of  a  tender  offer  may  be  more
difficult.  This may be beneficial to management in a hostile tender offer,  but
have an  adverse  impact on  stockholders  who may want to  participate  in such
tender offer.

   
         Control By Present Management. The Company's officers and directors, as
a group, beneficially owned 24.3% of the outstanding Common Stock of the Company
as of  September  5, 1997 and thus could in some  instances  exercise  effective
control over the Company.  The  Company's  Chief  Executive  Officer has pledged
substantially all the shares of the Company's Common Stock beneficially owned by
her to secure repayment of the Term Loan. See "Risk Factors - Restrictions under
Secured Financing."
    

         Volatility and Possible  Reduction in Price of Common Stock. The market
price of the Common Stock, like that of the securities of many other development
stage biotechnology companies, has been and may continue to be, highly volatile.
Factors such as  announcements  of  technological  innovations or new commercial
products by the Company or its  competitors,  disclosure  of results of clinical
testing  or  regulatory  proceedings,  governmental  regulation  and  approvals,
developments  in patent or other  proprietary  rights,  public concern as to the
safety of products  developed by the Company and general  market  conditions may
have a significant  effect on the market price of the Common Stock. In addition,
the stock market has experienced  and continues to experience  extreme price and
volume  fluctuations  which have effected the market price of many biotechnology
companies.  These broad  market  fluctuations,  as well as general  economic and
political  conditions,  may  adversely  effect the market price of the Company's
Common Stock.

         Dependence  on Third  Parties for  Manufacturing.  The Company does not
currently have  facilities  capable of  manufacturing  its product in commercial
quantities and, for the foreseeable future, the Company intends to rely on third
parties  to  manufacture  its  product.  If the  Company  were  to  establish  a
manufacturing  facility,  which it currently  does not intend to do, the Company
would  require  substantial  additional  funds and would be required to hire and
retain  significant  additional  personnel to comply with the extensive  current
Good Manufacturing  Practices ("cGMP") regulations of the FDA applicable to such
a facility. No assurance can be given that the Company would be able to make the
transition successfully to commercial production, if it chose to do so.

         Dependence on Third  Parties for  Marketing;  No Marketing  Experience.
Neither the Company nor any of its  officers  or  employees  has  pharmaceutical
marketing  experience.  The  Company  intends  to  enter  into  development  and
marketing  agreements  with third parties.  The Company  expects that under such
arrangements  it would act as a  co-marketing  partner or would grant  exclusive
marketing  rights  to its  corporate  partners  in  return  for  up-front  fees,
milestone payments and royalties on sales. Under these agreements, the Company's
marketing  partner  may have the  responsibility  for a  significant  portion of
development  of the  product  and  regulatory  approval.  In the event  that the
marketing  partner  fails to develop a  marketable  product or fails to market a
product  successfully,  the Company's business may be adversely affected. If the
Company were to market its products itself,  significant additional expenditures
and  management  resources  would be required to develop an internal sales force
and  there  can  be no  assurance  that  the  Company  would  be  successful  in
penetrating  the markets for any products  developed or that internal  marketing
capabilities would be developed at all.

   
         Shares  Eligible for Future Sale. As of September 5, 1997,  the Company
had  outstanding  14,847,793  shares of Common Stock and options and warrants to
acquire an additional  4,592,631  shares of Common Stock.  Of these  outstanding
shares, 10,390,943 shares are freely transferable without restriction or further
registration  under the  Securities  Act.  The  remaining  4,456,850  shares are
"restricted  securities"  as that term is defined in Rule 144 adopted  under the
Securities  Act.  Of  these  restricted  shares,  approximately  4,253,850  were
eligible  to be sold  under  Rule 144 as of  September  5,  1997  and  2,936,010
(including  2,733,010  eligible  to be sold under  Rule 144) are  covered by the
Registration  Statement of which this  Prospectus  forms a part.  Such 2,936,010
shares of restricted  Common Stock included in the Registration  Statement filed
with the Commission, will, if sold pursuant thereto, be freely tradeable without
restriction  under  the  Securities  Act,  except  that  any  shares  sold to an
"affiliate,"  as that term is defined under the Securities  Act, will be subject
to the resale  limitations  of Rule 144. As of September 5, 1997, in addition to
the  Warrants to purchase  698,251  shares of Common Stock issued in the Private
Placements,  the Options to purchase 588,316 shares of Common Stock and the Bank
Warrant to purchase  10,000 shares of Common Stock,  all of which are covered by
the  Registration  Statement of which this Prospectus  forms a part,  there were
outstanding options issued to officers, directors and consultants of the Company
(the "Employee  Options") to purchase an aggregate of 3,420,898 shares of Common
Stock, which are covered by an effective Registration Statement on Form S-8. The
4,592,631  shares of Common Stock  underlying such Warrants,  Options,  Employee
Options and the Bank Warrants  will,  if issued upon exercise of such  Warrants,
Options,  Employee  Options  and  Bank  Warrants  and  sold  pursuant  to  their
respective  registration  statements,  be freely tradeable  without  restriction
under the  Securities  Act,  except  that any shares of Common  Stock held by an
"affiliate,"  as that term is defined under the Securities  Act, will be subject
to the resale limitations of Rule 144. The existence of such Warrants,  Options,
Employee Options and Bank Warrants may adversely affect the Company's ability to
consummate future equity financings.  The future sale of a substantial number of
shares of Common  Stock by  existing  holders  of Common  Stock and  holders  of
warrants and options exercisable for Common Stock pursuant to Rule 144 under the
Securities Act or through effective registration  statements may have an adverse
impact on the market price of the Common Stock.
    

         Utilization of Carryforwards. At July 31, 1996, the Company had federal
net operating loss carryforwards of approximately $27,660,000 that expire in the
years 1997 to 2011. The Company also had investment tax credit  carryforwards of
approximately  $63,000 and research and experimentation tax credit carryforwards
of  approximately  $416,000  that  expire  in the years  1998 to 2011.  Ultimate
utilization/availability  of  such  net  operating  losses  and  credits  may be
significantly curtailed if a significant change in ownership occurs.

         Termination  of Company's  Auditors.  The  financial  statements of the
Company from  inception  to July 31, 1992  incorporated  by reference  into this
Registration  Statement,  were  audited by the  independent  accounting  firm of
Armus,  Harrison & Co. ("AHC"). On December 1, 1993, certain shareholders of AHC
terminated their  association with AHC (the "AHC  Termination"),  and AHC ceased
performing  accounting  and  auditing  services,  except for limited  accounting
services to be performed on behalf of the Company.  In June 1996,  AHC dissolved
and  ceased all  operations.  The  report of AHC with  respect to the  financial
statements  of the Company from  inception to July 31, 1992 is  incorporated  by
reference into this  Registration  Statement,  although AHC has not consented to
the incorporation of such report herein and will not be available to perform any
subsequent review procedures with respect to such report. Accordingly, investors
will be  barred  from  asserting  claims  against  AHC under  Section  11 of the
Securities  Act on the basis of the  incorporation  of such  report  herein.  In
addition,  in the event any persons seek to assert a claim against AHC for false
or misleading financial statements and disclosures in documents previously filed
by the  Company,  such claims will be adversely  affected  and possibly  barred.
Furthermore,  as a result of the lack of a consent from AHC to the incorporation
of its audit  report in this  Prospectus,  the  officers  and  directors  of the
Company  will be unable to rely on the  authority  of AHC as experts in auditing
and accounting in the event any claim is brought  against any such persons under
Section 11 of the Securities Act based on alleged false and misleading financial
statements and disclosures attributable to AHC. The discussion regarding certain
effects of the AHC  Termination  is not meant and should not be construed in any
way as legal advice to any party and any potential purchaser should consult with
his, her or its own counsel with respect to the effect of the AHC Termination on
a potential investment in the Common Stock of the Company or otherwise.

         The Company's sale of Common Stock and Warrants to accredited investors

Rule 506 thereunder, except that 115,000 shares were sold pursuant to Regulation
S under the Securities Act. Pursuant to stock purchase  agreements  entered into
by the  Company  with each of the Private  Placement  Investors  (the  "Purchase
Agreements") and the Term Loan amendment entered into with the bank, the Company
agreed to indemnify each of the Private Placement Investors and the bank (all of
whom are Selling Stockholders) against any liabilities, under the Securities Act
or  otherwise,  arising  out of or  based  upon any  untrue  or  alleged  untrue
statement of a material fact in the Registration Statement or this Prospectus or
by any omission of a material fact required to be stated  therein  except to the
extent  that  such  liabilities  arise out of or are  based  upon any  untrue or
alleged untrue statement or omission in any information  furnished in writing to
the Company by the Private Placement  Investors or the bank expressly for use in
the Registration  Statement.  Insofar as indemnification for liabilities arising
under the  Securities  Act may be  permitted to  directors,  officers or persons
controlling  the  Company  pursuant  to its  certificate  of  incorporation  and
by-laws, the Company has been informed that in the opinion of the Securities and
Exchange  Commission such  indemnification is against public policy as expressed
in the Act and is therefore unenforceable.

         The  Private  Placement  Investors  and the  bank  (except  the  Supply
Agreement  investors)  have the right,  at the  Company's  expense,  to have the
shares of Common Stock offered  hereby  registered for the offer and sale to the
public under the Securities  Act. The Private  Placement  Investors in the March
1994 Private Placement have the right to have the offer and sale of their shares
of Common  Stock  registered  through  August 3,  1997,  the  Private  Placement
Investors in the  September  1994 Private  Placement  have the right to have the
offer and sale of their shares of Common Stock registered  through September 14,
1997 and the Private Placement  Investors in the October 1994 and September 1995
Private  Placements have the right to have the offer and sale of their shares of
Common  Stock  registered  through  December  11,  1998.  The Private  Placement
Investors in the June 1996 Private  Placement  have the right,  at the Company's
expense,  to have the shares of Common Stock offered  hereby  registered for the
offer and sale to the public under the Securities Act until  September 13, 1999.
The Company has  determined  to include  the shares of Common  Stock  issued and
issuable to the Private Placement Investors in the 1995/1996 Private Placements,
the shares acquired pursuant to the Exercised Options and the Graska's shares of
Common Stock in this Registration Statement, although it has no obligation to do
so. In addition,  the Option Holders have the right to have the shares of Common
Stock  issuable upon the exercise of the Options  registered  on a  registration
statement at their  request.  The Company has determined to register such shares
herein. The investors in the March 1997 Private Placement have the right to have

effectiveness  of such  registration  statement  for three years  after  initial

                              PLAN OF DISTRIBUTION

         Shares of Common Stock currently outstanding and shares of Common Stock
issuable upon exercise of the Warrants,  the Options and the Bank Warrant may be
sold pursuant to this  Prospectus by the Selling  Stockholders.  These sales may
occur in privately  negotiated  transactions or in the  over-the-counter  market
through  brokers and dealers as agents or to brokers and dealers as  principals,
who  may  receive  compensation  in  the  form  of  discounts,   concessions  or
commissions  from the Selling  Stockholders or from the purchasers of the Common
Stock for whom the  broker-dealers  may act as agent or to whom they may sell as
principal, or both. Certain of the Selling Stockholders may also sell certain of
their shares of Common Stock pursuant to Rule 144 under the Securities  Act. The
Company has been advised by the Selling Stockholders that they have not made any
arrangements  relating to the distribution of the shares of Common Stock covered
by this Prospectus.  In effecting sales,  broker-dealers  engaged by the Selling
Stockholders may arrange for other broker-dealers to participate. Broker-dealers
will receive  commissions or discounts from the Selling  Stockholders in amounts
to be negotiated immediately prior to the sale.

         Upon  being  notified  by  a  Selling  Stockholder  that  any  material
arrangement  (other  than a  customary  brokerage  account  agreement)  has been
entered  into  with a broker or  dealer  for the sale of shares  through a block
trade, purchase by a broker or dealer, or similar transaction,  the Company will
file a supplemented  Prospectus pursuant to Rule 424(c) under the Securities Act
disclosing  (a) the name of each such  broker-dealer,  (b) the  number of shares
involved, (c) the price at which such shares were sold, (d) the commissions paid
or discounts or concessions allowed to such broker-dealer(s), (e) if applicable,
that such  broker-dealer(s)  did not  conduct  any  investigation  to verify the
information  set  out  or  incorporated  by  reference  in  the  Prospectus,  as
supplemented, and (f) any other facts material to the transaction.

         Certain of the Selling  Stockholders and any broker-dealers who execute
sales for the Selling Stockholders may be deemed to be "underwriters" within the
meaning of the  Securities Act by virtue of the number of shares of Common Stock
to be sold or resold by such persons or entities or the manner of sale  thereof,
or both.  If any of the Selling  Stockholders,  broker-dealers  or other holders
were determined to be  underwriters,  any discounts,  concessions or commissions
received by them or by brokers or dealers acting on their behalf and any profits
received by them on the resale of their  shares of Common  Stock might be deemed
underwriting discounts and commissions under the Securities Act.

         The Selling  Stockholders  have  represented  to the  Company  that any
purchase  or sale  of the  Common  Stock  by them  will  be in  compliance  with
Regulation M ("Regulation M") promulgated  under the Securities  Exchange Act of
1934, as amended (the "Exchange  Act"). In general,  Rule 102 under Regulation M
prohibits any person connected with a distribution of the Company's Common Stock
(the  "Distribution") from directly or indirectly bidding for, or purchasing for
any account in which he has a beneficial interest, any Common Stock or any right
to purchase  Common Stock, or attempting to induce any person to purchase Common
Stock or rights to purchase Common Stock, for a period of one business day prior
to and subsequent to completion of his  participation in the  Distribution  (the
"Distribution Period").

         During the Distribution  Period, Rule 104 ("Rule 104") under Regulation
M  prohibits  the  Selling  Stockholders  and any other  person  engaged  in the
Distribution from engaging in any stabilizing bid or purchasing the Common Stock
except for the purpose of  preventing  or retarding a decline in the open market
price of the Common Stock. No such person may effect any stabilizing transaction
to facilitate any offering at the market.  Inasmuch as the Selling  Stockholders
will be  reoffering  and  reselling  the Common  Stock at the  market,  Rule 104
prohibits them from effecting any stabilizing  transaction in  contravention  of
Rule 104 with respect to the Common Stock.

herein,  and upon the  authority  of said  firm as  experts  in  accounting  and
auditing.  The report of KPMG Peat  Marwick  LLP as it relates to the  financial
statements  for the period from August 24, 1981 (date of  inception) to July 31,
1996 is based on the report of Armus  Harrison & Co.  ("AHC") as to the  amounts
included therein for the period from August 24, 1981 (date of inception) to July
31, 1992.

   
===============================================================================
The accounting  firm of Armus,  Harrison  dissolved and ceased all operations in
June,  1996.  As a result  of such  dissolution,  investors  seeking  to sue and
recover damages from Armus, Harrison for material misstatements or omissions, if
any, in the  registration  statement  or  prospectus,  including  the  financial
statements, may be unable to do so. Armus, Harrison has not consented to the use
of its audit  report  and as a result,  investors  seeking  to  recover  damages
pursuant to Section 11 of the Securities  Act against Armus,  Harrison for false
and misleading statements,  if any, may be limited, and the lack of such consent
may preclude directors or officers of the Company from asserting a due diligence
defence      in      connection      with     a     Section      11      action.

Item 15. Indemnification of Directors and Officers

         Under  Section 145 of the  General  Corporation  Law of  Delaware  (the
"GCL")  a  corporation  may  indemnify  any  person  who was or is a party or is
threatened to be made a party to any  threatened,  pending or completed  action,
suit or proceeding,  whether civil,  criminal,  administrative  or investigative
(other than an action by or in the right of the  corporation),  by reason of the
fact  that  he  is or  was  a  director,  officer,  employee  or  agent  of  the
corporation,   or  is  or  was  serving  at  the  request  of  the  corporation,
partnership,   joint  venture,   trust  or  other  enterprise  against  expenses
(including  attorneys'  fees),  judgments,  fines and amounts paid in settlement
actually  and  reasonably  incurred  in  connection  with such  action,  suit or
proceeding if he acted in good faith and in a manner he  reasonably  believed to
be in or not opposed to the best interests of the corporation, and, with respect
to any criminal  action or  proceeding,  had no reasonable  cause to believe his
conduct was unlawful.

         A corporation also may indemnify any person who was or is a party or is
threatened to be made a party to any threatened,  pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor by
reason of the fact that he is or was a director,  officer,  employee or agent of
the  corporation,  or is or was serving at the request of the  corporation  as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other enterprise against expenses (including attorneys' fees)
actually  and  reasonably  incurred  by him in  connection  with the  defense or
settlement  of such  action or suit if he acted in good faith and in a manner he
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
corporation.  However,  in such an action by or on behalf of a  corporation,  no
indemnification may be made in respect of any claim, issue or matter as to which
the person is adjudged liable to the  corporation  unless and only to the extent
that the court  determines  that,  despite the  adjudication of liability but in
view of all the circumstances,  the person is fairly and reasonably  entitled to
indemnity for such expenses which the court shall deem proper.

         In addition,  the indemnification  provided by Section 145 shall not be
deemed exclusive of any other rights to which those seeking  indemnification may
be entitled under any bylaw,  agreement,  vote of stockholders or  disinterested
directors or  otherwise,  both as to action in his  official  capacity and as to
action in another  capacity  while  holding  such  office.  The  Certificate  of
Incorporation of the Company is consistent with Section 145 of the

                                      II-1

<PAGE>

GCL and its Bylaws  provide that each director,  officer,  employee and agent of
the Company shall be indemnified to the extent permitted by the GCL.

         In this  connection,  the  Company  has  entered  into  indemnification
agreements  (the  "Indemnity  Agreements")  with  each  of  its  directors.  The
Indemnity Agreements are consistent with the Company's By-laws and the Company's
policy to  indemnify  directors  to the fullest  extent  permitted  by law.  The
Indemnity  Agreements  provide for  indemnification of directors for liabilities
arising out of claims  against such  persons  acting as directors of the Company
(or any entity  controlling,  controlled  by or under  common  control  with the
Company)  due  to  any  actual  or  alleged  breach  of  duty,  neglect,  error,
misstatement,  misleading statement,  omission or other act done, or suffered or
wrongfully  attempted  by such  directors,  except  as  prohibited  by law.  The
Indemnity  Agreements  also provide for the  advancement  of costs and expenses,
including  attorneys'  fees,  reasonably  incurred by  directors in defending or
investigating any action,  suit,  proceeding or claim, subject to an undertaking
by such directors to repay such amounts if it is ultimately determined that such
directors are not entitled to  indemnification.  The Indemnity  Agreements cover
future acts and omissions of directors for which actions may be brought.

         The  Indemnity  Agreements  also  provide  that  directors,   officers,
employees  and agents are  entitled  to  indemnification  against  all  expenses
(including  attorneys'  fees)  reasonably  incurred  in  seeking  to  collect an
indemnity  claim or to obtain  advancement  of expenses  from the  Company.  The
rights of directors  under the  Indemnity  Agreements  are not  exclusive of any
other rights  directors may have under  Delaware  law, any  liability  insurance
policies that may be obtained,  the Company's By-Laws or otherwise.  The Company
would not be  required  to  indemnify  a director  for any claim  based upon the
director  gaining in fact a personal  profit or advantage to which such director
was not  legally  entitled,  any  claim for an  accounting  of  profits  made in
connection  with a violation of Section 16(b) of the Securities  Exchange Act of
1934 or a similar  state or common law  provision or any claim  brought about or
contributed to by the dishonesty of the director.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  Registrant  pursuant  to  the  foregoing  provisions,   or  otherwise,  the
registrant  has been advised that in the opinion of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the registrant of expenses
incurred or paid by a director,  officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

Item 17.   Undertakings

The undersigned registrant hereby undertakes:

           (1) To file,  during  any  period in which  offers or sales are being
made, a post-effective amendment to this registration statement:

(i)  To include any  prospectus  required by Section  10(a)(3) of the Securities
     Act of 1933;

(ii) To  reflect  in the  prospectus  any  facts or  events  arising  after  the
     effective  date  of  the   registration   statement  (or  the  most  recent
     post-effective amendment thereof) which,  individually or in the aggregate,
     represent  a  fundamental  change  in  the  information  set  forth  in the
     registration  statement.  Notwithstanding  the  foregoing,  any increase or
     decrease  in volume of  securities  offered (if the total  dollar  value of
     securities  offered  would not exceed  that which was  registered)  and any
     deviation from the low or high end of the estimated  maximum offering range
     may be  reflected  in the form of  prospectus  filed  with  the  Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in the volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set  forth in the  "Calculation  of  Registration  Fee"  table in the
     effective registration statement.

(iii)To  include  any  material   information   with  respect  to  the  plan  of
     distribution not previously disclosed in the registration  statement or any
     material change to such information in the registration statement:

                                      II-3

<PAGE>
           Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if
the  registration  statement  is on Form  S-3,  Form  S-8 or Form  F-3,  and the
information  required  to be  included in a  post-effective  amendment  by those
paragraphs is contained in the periodic reports filed by the Registrant pursuant
to Section 13 or Section 15(d) of the  Securities  Exchange Act of 1934 that are
incorporated by reference in the registration statement.

           (2) That,  for the purpose of  determining  any  liability  under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

           (3)  To  remove  from  registration  by  means  of  a  post-effective
amendment  any of the  securities  being  registered  which remain unsold at the
termination of the offering.

           (4)  That,  for  purposes  of  determining  any  liability  under the
Securities Act of 1933, each filing of the  Registrant's  annual report pursuant
to Section  13(a) or Section 15(d) of the  Securities  Exchange Act of 1934 (and
where  applicable,  each  filing of an employee  benefit  plan's  annual  report
pursuant  to  Section  15(d) of the  Securities  Exchange  Act of 1934)  that is
incorporated by reference in this Registration Statement shall be deemed to be a
new Registration  Statement relating to the securities offered therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

           (5) Insofar as  indemnification  for  liabilities  arising  under the
Securities Act of 1933 may be permitted to directors,  officers and  controlling
persons of the Registrant pursuant to the foregoing provisions or otherwise, the
Registrant  has been advised that in the opinion of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the Registrant of expenses
incurred or paid by a director,  officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
