agents targeting DNA topoisomerase I. The expanded seven-membered lactone E-ring that characterizes hCPT enhances the plasma stability of the drug and reinforces the inhibition of topoisomerase I (Topo I) compared with conventional six-membered CPT. In an attempt to improve the antitumour activity of hCP, a series of novel hCPT derivatives conjugating with dihydropyridine derivates were designed and synthesized
同型喜树碱(hCPT)代表了针对DNA拓扑异构酶I的新一代抗肿瘤药物。与传统的六种抗肿瘤药物相比,表征hCPT的扩展的七元内酯E环增强了药物的血浆稳定性并增强了对拓扑异构酶I(Topo I)的抑制作用。成员的CPT。为了改善hCP的抗肿瘤活性,基于将7-甲酰基高喜树碱与不同的二氢吡啶衍生物偶联的合成路线,设计并合成了与二氢吡啶衍生物缀合的一系列新颖的hCPT衍生物。大多数合成的化合物对肿瘤细胞系A549,MDA-MB-435和HCT116表现出良好的细胞毒活性。此外,这类化合物显示出与CPT相当或更高的Topo I抑制活性。
