A novel series of C-8 ester derivatives of leinamycin are described. Condensation of N-substituted amino acids or carboxylic acids containing polyether moiety with leinamycin resulted in the C-8 ester derivatives with good antitumor activity in several experimental models. Among these derivatives, compound 4e, which has five ethylene glycol ether units in the C-8 acyl group, showed potent antitumor
描述了新型的莱那霉素的C-8酯衍生物系列。N-取代的氨基酸或含有聚醚部分的羧酸与莱那霉素的缩合导致在一些实验模型中具有良好抗肿瘤活性的C-8酯衍生物。在这些衍生物中,化合物4e在C-8酰基中具有五个乙二醇醚单元,显示出对人肿瘤异种移植物的有效抗肿瘤活性。结合二硫杂环戊酮部分的修饰应用于这些C-8酯衍生物,其中一些还显示出良好的抗肿瘤活性。
