Dolastatin 10 (1) is a potent antineoplastic pentapeptide. Novel dolastatin 10 analogs each modified at one of the constituent amino acid derivatives, were synthesized and their antitumor activity was evaluated against P388 leukemia in mice. The structural requirements for antitumor activity are discussed. Some of the analogs, 31c, 35c, 38b, and 50c showed excellent activity in vivo. Highly active 50c
Dolastatin 10(1)是有效的抗肿瘤五肽。合成了各自在组成氨基酸衍生物之一上修饰的新型dolastatin 10类似物,并评估了其对小鼠中P388白血病的抗肿瘤活性。讨论了抗肿瘤活性的结构要求。一些类似物31c,35c,38b和50c在体内显示出出色的活性。选择没有噻唑基团1的高活性50c作为抗肿瘤剂进行进一步开发。
