Two active sites responsible for antitumor activity, an oxirane ring and an alpha-methylene-cyclopentanone moiety, have been extracted from studies on the structure-activity relationship of the cytotoxic diterpenoids isolated from Rabdosia shikokiana. Series of the simplified cyclopentanone derivatives containing both of the two active sites in the molecule have been synthesized and evaluated for cytotoxicity
从对鼠疫拉比多菌分离的细胞毒性二萜类化合物的结构-活性关系的研究中,提取了负责抗肿瘤活性的两个活性位点:环氧乙烷环和α-亚甲基-环戊酮部分。已经合成了一系列在分子中包含两个活性位点的简化的环戊酮衍生物,并评估了其对P 388细胞的细胞毒性。具有两个活性位点的化合物在1微克/毫升的浓度下均显示出细胞毒性,而具有单个活性位点的化合物则没有活性。
