A current study shows that sodium dichloroacetate (DCA) can induce cancer cell apoptosis and inhibit tumor growth, but its cytotoxic activity is low (IC50> 1000 μM for A549). In this paper, a variety of DCA derivatives were synthesized, and their cytotoxic activities were evaluated. The result showed that the N-phenyl-2, 2-dichloroacetamide analogues had satisfactory potencies. Among them, N-(3-iodophenyl)-2, 2-dichloroacetamide (3e), an ...
