vitro. Relationships between chain nature and biological properties were sought. Lactones with a pentyl or hexyl substituent at C-11 are the most active ones. The introduction of a functional group at the side chain of C-11 modified the potency; carboxylic acid and primary amine decreased the cytotoxicity, whereas a cyano group increased the activity. An extensive structure-activity relationship study
已经合成了一组双取代的四环内酯,并测试了其潜在的抗肿瘤活性。它们中的几种在体外对L1210和HT-29结肠细胞具有明显的细胞毒性。寻找链性质和生物学性质之间的关系。在C-11上具有戊基或己基取代基的内酯是活性最高的内酯。在C-11的侧链上引入官能团可改变效力。羧酸和伯胺降低了细胞毒性,而氰基提高了活性。对这些衍生物,包括碳同系物和生物等排体,进行了广泛的构效关系研究。讨论了这些化合物的合成和细胞毒性。两种内酯被认为是潜在的先导化合物。
