of CA-4 showed potent antitubulin activity and cytotoxicity against murine Colon 26 adenocarcinoma in vitro. Some of the compounds which were potent in vitro were evaluated in the murine tumor model Colon 26 in vivo. Among these, 13bHCl, 21aHCl, and 21bHCl showed significant antitumor activity in the animal model, while CA-4 was ineffective. 13bHCl and 21aHCl were further evaluated in two murine tumor
合成了一系列康普他汀A-4(CA-4)类似物,并评估了它们对鼠结肠26腺癌的细胞毒性作用以及对微管蛋白聚合的抑制活性。由于CA-4的水溶性有限,因此设计目标化合物可通过引入含氮基团来提高溶解度。在合成的化合物中,氨基取代CA-4的酚OH的化合物在体外对小鼠结肠26腺癌表现出有效的抗微管蛋白活性和细胞毒性。在小鼠肿瘤模型Colon 26中体内评估了一些体外有效的化合物。其中,13bHCl,21aHCl和21bHCl在动物模型中显示出显着的抗肿瘤活性,而CA-4无效。在两种鼠类肿瘤模型(结肠38和3LL)和人类异种移植物HCT-15中进一步评估了13bHCl和21aHCl。这些化合物显示出与CDDP相当或优于CDDP的有效抗肿瘤活性。还讨论了这一系列化合物的构效关系。
