摘 要:为考察4′-去甲基表鬼臼毒素4位上取代基结构变化与抗肿瘤活性的关系,设计并合成了23个标题化合物。体外L_(1210)白血病细胞与KB细胞生长抑制试验的结果表明,化合物11,16和18的抗肿瘤活性超过依托泊甙,化合物8的活性与依托泊甙相当。Twenty three 4-(2-amido-2-ethoxycarbonyl) ethylsulfenyl-4-deoxy-4'-demethylepipodophyllotoxin analogues were synthesized by three steps, in which trifluoroacetic acid was used as a condensation agent of 4'-demethylepipodophyllotoxin with L-cysteine ethyl ester hydrochloride without any protection of phenolic hydroxy and amino groups. All compounds were screened in vitro against L_(1210) leukemia and KB cells, in which, compounds 11, 16 and 18 exhibited more potent antitumor activity than etoposide.
