An extensive study has been made on the antitumor activity of several iridoid glycosides and their aglycones in mice bearing the experimental tumor leukemia P388. Most of the aglycones were found to be active. Among them, scadoside methyl ester aglycone (SMEH) showed the most potent activity, and it was furhter tested against several kinds of experimental tumor. None of the glucosides showed any activity. Our observations suggest that the hemiacetal structure of iridoid aglycones plays a significant role in the antitumor activity, as in the case of the antimicrobial activity reported previously.
对几种环烯醚萜苷及其糖苷在实验性肿瘤白血病P388小鼠体内的抗肿瘤活性进行了广泛研究。大多数糖苷被发现具有活性。其中,scadoside methyl ester aglycone (SMEH)表现出最强活性,并进一步对几种实验性肿瘤进行了测试。这些苷类均未显示出任何活性。我们的观察表明,环烯醚萜苷半缩醛结构在抗肿瘤活性中起着重要作用,正如先前报道的抗菌活性一样。
