Design, synthesis and biological evaluation of N-arylphenyl-2,2- dichloroacetamide analogues as anti-cancer agents

摘要

Our earlier research has shown that N-phenyl-2,2-dichloroacetamide analogues had much higher anti-cancer activity than the lead compound sodium dichloroacetate (DCA). In this current study, a variety of N-arylphenyl-2,2- dichloroacetamide analogues were synthesized via Suzuki coupling reaction and their anti-cancer activity was evaluated. The results showed that N-terphenyl-2,2-dichloroacetamide analogues had satisfactory anti-cancer activity. Among them, N-(3,5-bis(benzo[d][1,3]dioxol-5-yl)phenyl)-2,2- dichloroacetamide (6 k) had an IC50 of 2.40 μM against KB-3-1 cells, 1.04 μM against H460 cells and 1.73 μM against A549 cells.
