摘要:
Benzimidazole-based analogues of cis- and trans-Epo A, 2 and 3, have been prepared through stereoselective total synthesis. Both compounds are highly potent antiproliferative agents, but the effects of side-chain replacement on cellular activity are ambivalent. While significantly enhanced potency is observed against a drug-sensitive human cancer cell line, 2 and 3 more susceptible to P-gp-mediated drug efflux than Epo A or frans-Epo A. © 2006 Wiley-VCH Verlag GmbH & Co.
