Synthesis and anticancer effects of pongamol derivatives on mitogen signaling and cell cycle kinases

A series of oxazole and pyrazole derivatives of pongamol (1) were designed and synthesized to examine their anti-cancer activity. The cytotoxicity of these compounds was examined in three different human tumor cell lines, IMR-32, HeLa and Jurkat. Although all compounds tested were quite effective than the pongamol against all the three different types of cancer cell lines examined, the compounds (2), (5), and (6) were found to be the most active compounds of this series.
