Exhibit 10.36

                             NOTE PURCHASE AGREEMENT

         This NOTE PURCHASE AGREEMENT (this "Agreement"), dated as of April 26,
2007, is entered into by and among Somanta Pharmaceuticals, Inc., a Delaware
corporation (the "Company"), and Access Pharmaceuticals, Inc., a Delaware
corporation (the "Lender").

         WHEREAS, the Lender has agreed to lend to the Company on the date
hereof the aggregate principal amount of $33,461.89 and may lend to the Company
from time to time after the date hereof an additional aggregate principal
amounts, all as hereinbelow provided.

         NOW, THEREFORE, in consideration of the mutual promises and covenants
in this Agreement, the parties hereto agree as follows:

         1.       (a)      Initial Loan Amount. On the date hereof (the
"Closing"), the Lender shall pay, on behalf of the Company, the initial loan
amount of $33,461.89 (the "Loan") by check or wire transfer pursuant to wire
transfer instructions furnished by the Company. At the Closing, the Company
shall issue to the Lender a promissory note in the form of Exhibit A hereto,
initially reflecting outstanding principal in the amount of the Loan (the
"Note"). In addition, at the Closing, the Company shall execute, deliver and/or
authorize, as the case may be, (i) the Patent Collateral Assignment and Security
Agreement in the form of Exhibit B hereto (the "Patent Agreement"), (ii) the
Trademark Collateral Assignment and Security Agreement in the form of Exhibit C
hereto (the "Trademark Agreement"), (iii) the Security Agreement in the form of
Exhibit D hereto (the "Security Agreement"), and (iv) all other instruments and
documents, including, without limitation, Uniform Commercial Code financing
statements, required to be delivered pursuant to the Patent Agreement, the
Trademark Agreement and the Security Agreement (such other instruments and
documents, with the Patent Agreement, the Trademark Agreement and the Security
Agreement, the "Security Documents," which Security Documents, together with
this Agreement, and the Note, are collectively referred to herein as the "Loan
Documents").

                  (b)      Possible Additional Loan Amounts. Upon a request by
the Company in the form of Exhibit E hereto, Lender may, in its sole and
absolute discretion, advance additional Loan amounts requested by the Company,
whereupon Lender shall annotate the Table of Advances and Repayment of Principal
attached to the Note to record such Loan advance, thereby increasing the Loan
and the then outstanding principal balance owed under the Note by the amount of
such advance. The Company hereby authorizes Lender to make such annotations and
such annotations shall be deemed to be amendments to the Note duly authorized
and agreed by the Company.

         2.       Representations, Warranties and Certain Covenants of the
Lender. The Lender hereby represents, warrants and covenants to the Company as
to itself, as follows:

                  (a)      The Lender understands that the offering and sale of
         the Note are intended to be exempt from registration under the
         Securities Act of 1933, as amended (the "Securities Act"), by virtue of
         Section 4(2) thereof and the provisions of Regulation D promulgated
         thereunder and, in accordance therewith and in furtherance thereof, the
         Lender further represents and warrants to and agrees with the Company
         as follows:
<PAGE>

                           (i)      the Lender is purchasing the Note for such
                  Lender's own account, for investment only, and not with a view
                  to, or for sale in connection with, any distribution of the
                  Note in violation of the Securities Act, any rule or
                  regulation thereunder, or any state securities laws;

                           (ii)     the Lender understands that all documents,
                  records and books pertaining to this investment have been made
                  available for inspection by the Lender, the Lender's counsel
                  and/or the Lender's accountants, the Lender has carefully
                  reviewed all such documents, and understands and has relied
                  only on information provided to such Lender in writing by the
                  Company relating to this investment;

                           (iii)    the Lender and/or the Lender's advisor(s)
                  have had a reasonable opportunity to ask questions of and
                  receive answers from a person or persons acting on behalf of
                  the Company concerning the offering of the Note, and all such
                  questions have been answered to the full satisfaction of such
                  Lender;

                           (iv)     the Lender is not relying on the Company
                  with respect to the investment considerations of the Lender
                  relating to this investment;

                           (v)      the Lender (A) will not sell, transfer,
                  pledge, assign or otherwise dispose of the Note without
                  registration thereof under the Securities Act or pursuant to
                  an exemption from registration and, if pursuant to an
                  exemption from registration and if requested by the Company,
                  receipt by the Company of an opinion of counsel in form and
                  substance satisfactory to the Company and its counsel to the
                  effect that such registration is not required, and (B) fully
                  understands and agrees that the Lender must bear the economic
                  risk of the Lender's investment for an indefinite period of
                  time because, among other reasons, the Note has not been
                  registered under the Securities Act or under the securities
                  laws of certain states and, therefore, cannot be resold,
                  transferred, pledged, assigned or otherwise disposed of unless
                  they are subsequently registered under the Securities Act and
                  under the applicable securities laws of such states or unless
                  an exemption from such registration is available; and

                           (vi)     the Lender understands that sales or
                  transfers of the Note may be made only in compliance with
                  certain state securities laws, and the Note will bear a legend
                  reflecting the transfer restrictions imposed thereon and a
                  notation may be made in the records of the Company restricting
                  the transfer of the Note in a manner consistent with the
                  foregoing.

                  (b)      The Lender is an "accredited investor" within the
         meaning of Rule 501 of Regulation D, as promulgated by the Securities
         and Exchange Commission, as presently in effect.

         3.       Representations and Warranties of the Company. The Company
hereby represents and warrants to the Lender as follows as of the date set forth
above (and, in the event of any advance under the Note, as of the date of any
request for an advance under the Note, as applicable):

         (a)      Corporate Power; Binding Effect; Non-Contravention. The
Company has all requisite power and full legal right to execute and deliver this
Agreement and each of the other Loan Documents, and to perform all of its
obligations hereunder and thereunder in accordance with the respective terms
hereof and thereof. The Loan Documents and the transactions contemplated thereby
have been duly approved and authorized by all requisite corporate action on the
part of the Company, and the Loan Documents have been duly executed and
delivered by the Company and constitute the legal, valid and binding obligations
of the Company, enforceable against it in accordance with their respective
terms. The execution, delivery and performance by the Company of the Loan
Documents in accordance with their respective terms, and the consummation by the
Company of the transactions contemplated thereby, will not result (with or
without the giving of notice or the lapse of time or both) in any conflict,
violation, breach, or default, or the creation of any lien or encumbrance of any
nature ("Liens") upon any assets of the Company, (other than pursuant to the
Security Documents), or the termination, acceleration, vesting or modification
of any right or obligation, under or in respect of (i) the Certificate of
Incorporation or by-laws of the Company, each as amended to date, (ii) any
judgment, decree, order, statute, rule, or regulation binding on or applicable
to the Company, or (iii) any agreement or instrument to which the Company is a
party or by which it or any of its assets is or are bound.

         (b)      Properties, Leases, Etc. Except with respect to Liens in favor
of the Lender pursuant to the Security Documents, the Company has (A) good and
marketable title to all of the assets and properties owned by it, free and clear
of all Liens, (B) valid title to the lessee interest in all assets and
properties leased by the Company as lessee, free and clear of all Liens, and (C)
full right to hold and use all of its assets and properties used in or necessary
to its businesses and operations, in each case all free and clear of all Liens,
and in each case subject to applicable laws and the terms of any lease under
which the Company leases such assets or properties as lessee. All such assets
and properties are in good condition and repair, reasonable wear and tear
excepted, and are adequate and sufficient to carry on the businesses of the
Company as presently conducted. The Company does not own any real property or
any interest (other than a leasehold interest) in any real property. The
Company's leasehold interests are subject to no Lien, and the Company is in
quiet possession of the properties covered by such leases. The Company's
leasehold interests are subject to no Lien caused by the Company, and the
Company is in quiet possession of the properties covered by such leases.

         (c)      Tax Matters. The Company has timely filed all tax returns
required to be filed by it, each such tax return has been prepared in compliance
with all applicable laws and regulations, and all such tax returns are true and
accurate in all material respects. All taxes due and payable by the Company have
been paid in respect of any period ending on or before the date hereof, and the
Company will not be liable for any additional taxes in respect of any taxable
period ending on or before the date hereof in an amount that exceeds the
corresponding reserve therefor, if any, reflected in the accounting records of
the Company as of the date hereof. No claim has ever been made by a taxing
authority in a jurisdiction where the Company does not pay tax or file tax

                                      -3-
<PAGE>

returns that the Company is or may be subject to taxes assessed by such
jurisdiction. There are no Liens for taxes (other than current taxes not yet due
and payable) on the assets of the Company. There is no action, suit, taxing
authority proceeding, or audit with respect to any tax now in progress, pending,
or, to the Company's knowledge, threatened, against or with respect to the
Company. No deficiency or proposed adjustment in respect of taxes that has not
been settled or otherwise resolved has been asserted or assessed by any taxing
authority against the Company. The Company has not consented to extend the time
in which any tax may be assessed or collected by any taxing authority. The
Company has not requested or been granted an extension of the time for filing
any tax return to a date on or after the Closing. The Company has withheld and
paid all taxes required to have been withheld and paid by it in connection with
amounts paid or owing to any employee, creditor, independent contractor or other
third party.

         (d)      Governmental and Other Third-Party Consents. Except for
filings or other notices required by applicable federal and state securities
laws (which will be completed by the Company within the applicable periods), no
consent, approval or authorization of, or registration, designation, declaration
or filing with, any governmental authority, federal or other, or any other
person or entity is required on the part of the Company in connection with its
execution, delivery or performance of this Agreement and the Note and its
consummation of the transactions contemplated hereby and thereby, or the
continued conduct of the present business of the Company after the Closing.

         (e)      Compliance with Securities Laws. Assuming the accuracy of the
representations of the Lender contained in Section 2 hereof, the offer, issuance
and delivery of the Note as contemplated by this Agreement are exempt from the
registration requirements of the Securities Act, and are exempt from
registration or qualification under applicable states' securities laws. Neither
the Company nor anyone authorized by the Company to act on its behalf will
hereafter offer to sell, solicit offers to buy, or sell, any securities of the
Company so as to subject the offer, issuance and sale of the Note to the
registration requirements of the Securities Act.

         (f)      Brokers. No finder, broker, agent or other intermediary has
acted for or on behalf of the Company in connection with the negotiation or
consummation of the transactions contemplated hereby, and no fee will be payable
by the Company to any such person in connection with such transactions.

         (g)      Disclosure. No representation or warranty by the Company in
this Agreement or any other Loan Document, in any schedule to this Agreement or
any other Loan Document, or in the Note, contains or will contain any untrue
statement of a material fact or omits or will omit to state a material fact
required to be stated herein or therein or necessary to make the statements
contained herein or therein not false or misleading.

         (h)      Other Representations, Warranties and Covenants. All
representations, warranties and other statements of fact made by the Company in
the Agreement and Plan of Merger, by and among the Company, the Lender and the
other parties thereto, dated as of April 18, 2007 (the "Merger Agreement"), are
true and correct. The Company has fully performed all of its covenants and
duties set forth in the Merger Agreement and required to be performed by the

                                      -4-
<PAGE>

Company as of the date hereof (and as of the date of any request for an advance
under the Note, as applicable).

         4.       Indemnification by the Company. The Company agrees to
indemnify and hold harmless the Lender and the officers, directors, and
affiliates and each other person, if any, who controls the Lender within the
meaning of Section 15 of the Securities Act, from and against any and all loss,
liability, claim, damage and expense whatsoever (including, but not limited to,
any and all expenses reasonably incurred in investigating, preparing or
defending against any litigation, commenced or threatened or any claim
whatsoever) arising out of or based upon any false representation or warranty or
breach or failure by the Company to comply with any covenant or agreement made
by the Company herein or in any other Loan Document furnished by the Company to
any of the foregoing in connection with this transaction.
