Exhibit 31.1

                        INTERIM SECTION 302 CERTIFICATION
                                  CERTIFICATION

I, Martin Schacker, certify that:

1.       I have reviewed this  quarterly  report  of Tetragenex Pharmaceuticals,
         Inc. on Form 10-QSB for the period ended September 30, 2007;

2.       Based on  my  knowledge,  this  report  does  not  contain  any  untrue
         statement of a material fact or omit to state a material fact necessary
         to make the statements made, in  light of the circumstances under which
         such statements were made, not misleading with  respect to  the  period
         covered by this report;

3.       Based on my knowledge, the financial statements,  and  other  financial
         information included in this report, fairly  present  in  all  material
         respects the financial condition, results of  operations and cash flows
         of the small business issuer as of, and for,  the  periods presented in
         this report;

4.       The  small  business  issuer's  other  certifying  officer  and  I  are
         responsible for establishing and maintaining  disclosure  controls  and
         procedures (as defined in Exchange Act  Rules  13a-15(e) and 15d-15(e))
         for the small business issuer and have:

         (a)      Designed such disclosure  controls and procedures,  or  caused
                  such disclosure controls and procedures to be  designed  under
                  our supervision, to ensure that material information  relating
                  to  the  small  business  issuer  including  its  consolidated
                  subsidiaries, is made known  to  us  by  others  within  those
                  entities,  particularly  during  the  period  in  which   this
                  quarterly report is being prepared;

         (b)      Evaluated the effectiveness of  the  small  business  issuer's
                  disclosure  controls  and  procedures  and  presented  in this
                  report  our   conclusions  about   the  effectiveness  of  the
                  disclosure controls and procedures,  as  of  the  end  of  the
                  period covered by this report based on such evaluation; and

         (c)      Disclosed in this report any  change  in  the  small  business
                  issuer's  internal   control  over  financial  reporting  that
                  occurred during the small business issuer's most recent fiscal
                  quarter (the small business issuer's  fourth fiscal quarter in
                  the case of an annual report) that has materially affected, or
                  is reasonably likely to material affect,  the  small  business
                  issuer's internal control over financial reporting: and

5.       The  small  business  issuer's  other  certifying  officer  and  I have
         disclosed, based on our most recent evaluation of internal control over
         financial reporting, to the small business issuer's  auditors  and  the
         audit committee of the small business issuer's board  of  directors (or
         persons performing the equivalent functions):

         (a)      All significant deficiencies and material  weaknesses  in  the
                  design  or  operation  of   internal  control  over  financial
                  reporting which are reasonably  likely to adversely affect the
                  small business issuer's ability to  record, process, summarize
                  and report financial information; and

         (b)      Any fraud, whether or not material, that  involves  management
                  or other employees who have a significant role  in  the  small
                  business issuer's internal control over financial reporting.
