Design, synthesis and cytotoxic activity of certain novel chalcone analogous compounds

Abstract

A series of chalcone analogous compounds were designed and synthesized. Replacing/substituting the enone or ethylenic bridge of the parent chalcone with rigid heterocyclic moieties or substituted aromatic amines gave nineteen target compounds. Their cytotoxic activities were screened against both breast and liver cancer cells as well as breast and liver normal cells. Target compounds were also evaluated for their inhibition activity of tubulin beta polymerization. Target compound 2e, 3a, 3b, 3c, 4a-4d, 5a, 5b and 6 showed broad spectrum excellent anticancer activity against both MCF-7 and HepG2. Compound 4a showed the most TUBb inhibition activity.
