  Substituted 2,5‘-Bi-1H-benzimidazoles:  Topoisomerase I Inhibition and Cytotoxicity

  摘要：

  Several 2'-aryl-5-substituted-2,5'-bi-1H-benzimidazole derivatives were synthesized and evaluated as topoisomerase I poisons and for their cytotoxicity toward the human lymphoblast cell line RPMI 8402. This study focused on 18 2,5'-bi-1H-benzimidazole derivatives which contained either a 5-cyano, a 5-(aminocarbonyl), or a 5-(4-methylpiperazinyl) group. Among these bibenximidazoles, the pharmacological activity of 2'-phenyl derivatives and the influence of the different positional isomers of either a 2'-tolyl group or a 2'-naphthyl moiety on cytotoxicity and topoisomerase I inhibitory activity were determined.
