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 anticancer 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 mu M against KB-3-1 cells, 1.04 mu M against H460 cells and 1.73 mu M against A549 cells.

Novel N-phenyl dichloroacetamide derivatives as anticancer reagents: Design, synthesis and biological evaluation
摘要:
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 mu M 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 optimized lead compound, has an IC50 against A549 as low as 4.76 mu M. Furthermore, it can induce cancer cell apoptosis and has a low toxicity in mice (LD50 = 1117 mg/kg). (C) 2010 Elsevier Masson SAS. All rights reserved.
