In order to develop novel chemotherapeutic agents with potent anticancer activities, we designed four series of novel compounds employing hybridization strategy. Twenty novel dihydroartemisinin-coumarin hybrids, 10a–e, 11a–e, 12a–e, 13a–e, were synthesized via click chemistry in this study and their structures were characterized by HRMS and NMR. The cytotoxic activities were measured by MTT assay against three cancer cell lines (HCT-116, MDA-MB-231, and HT-29) under normoxic or anoxic conditions, respectively. The target compounds exhibited moderate activity with IC50 values in the 0.05–125.40 μM range, and these compounds exhibited better activity against HT-29 cell line under anoxic condition. The cytotoxic activities of most compounds under anoxic condition displayed one- to 10-fold greater activity than under normoxic condition. Compounds 10a–e showed better selectivity against the HT-29 cell line than the other two cell lines. These results indicated that our design of CA IX inhibitors does correspond with its action mode to some degree and deserves further investigation.
为开发新型化疗药物,我们采用杂化策略设计了4类新型化合物。本研究通过点击化学合成了20种双氢青蒿素-香豆素杂化物(10a-e,11a-e,12a-e,13a-e),并通过高分辨质谱(HRMS)和核磁共振(NMR)对其结构进行了表征。我们在常氧或缺氧条件下,使用MTT法分别对3种癌细胞系(HCT-116、MDA-MB-231和HT-29)进行了细胞毒性活性测试。目标化合物表现出中等活性,IC50值在0.05至125.40微摩尔范围内,其中大部分化合物在缺氧条件下对HT-29细胞显示出更好的活性。大多数化合物在缺氧条件下的活性比常氧条件下高出1至10倍。化合物10a-e对HT-29细胞的选择性优于其他两种细胞系。这些结果表明,我们设计的CA IX抑制剂与其作用模式在一定程度上相符,值得进一步研究。
