A series of novel 10-substituted camptothecin analogs (3–10) with a carbamate linker were synthesized, and their biological activities were evaluated. The amino acid-linked carbamate derivatives (8–10) of the camptothecin-type natural product not only possessed good to excellent inhibitory activity against three human tumor cell lines K562, HepG2, and HT-29, but also showed significantly less cytotoxicity
一系列新颖的10-取代喜树碱类似物(的3 - 10)与氨基甲酸酯接头合成,和它们的生物活性进行了评价。的氨基酸连接的氨基甲酸酯衍生物(8 - 10)喜树碱类天然产物不仅具有良好至优异的抑制活性对三种人类肿瘤细胞系K562,HepG2细胞,和HT-29的,但也表现出显著更少的细胞毒性对正常人细胞HEK293(半数最大抑制浓度> 10μM)。化合物9的选择性相对于正常细胞,抗肿瘤细胞的活性至少比喜树碱高250倍。初步测试结果表明,与10-羟基喜树碱相比,这些化合物的溶解度也有所提高。
