Synthesis of novel pyrrole and pyrrolo[2,3-d]pyrimidine derivatives bearing sulfonamide moiety for evaluation as anticancer and radiosensitizing agents.

Pyrroles and pyrrolo[2,3-d]pyrimidines were reported to act as potent anticancer agents, in this work, a series of novel 2-substituted-3-cyano-4-phenyl-pyrrole 5, 6, 11-18, and 5-phenyl-pyrrolo[2,3-d]pyrimidine derivatives 7-10, 19-24 bearing either sulfathiazole or sulfapyridine were synthesized. The structures of these compounds were confirmed by elemental analysis, IR, (1)H NMR and mass spectral data. All the newly synthesized compounds were evaluated for their in vitro cytotoxicity against liver and breast cancer cell line (HEPG2 and MCF7).

Synthesis of some new pyrazole and pyrimidine derivatives carrying a sulfonamide moiety of expected antitumor activity and study of the synergistic effect of gamma-irradiation.

Several novel pyrazole (11-18) and pyrimidine (19-23) derivatives were synthesized starting from different sulfonamides and different active methylenes. The synthesized compounds were characterized by elemental analysis, IR, 1H-NMR and mass spectral data. The obtained compounds were screened as antitumor agents against human tumor cell line.
