12 novel scopoletin-isoxazole and scopoletin-pyrazole hybrids were designed, synthesized and their chemical structures were confirmed by HR-MS, IR, 1H NMR and 13C NMR spectra. The anticancer activities of the newly synthesized compounds were evaluated in vitro against three human cancer cell lines including HCT-116, Hun7 and SW620 by MTT assay. The screening results showed that six compounds (9a, 9c
设计,合成了12种新颖的草素-异恶唑和草素-吡唑杂化物,并通过HR-MS,IR,1 H NMR和13 C NMR谱图确认了它们的化学结构。通过MTT分析,体外评估了新合成的化合物对三种人类癌细胞系包括HCT-116,Hun7和SW620的抗癌活性。筛选结果表明,六种化合物(9a,9c,9d,12a,18b和18d)显示出有效的细胞毒活性,IC 50为值低于20μM。此外,我们进一步评估了六种化合物对人类正常组织细胞系HFL-1的生长抑制活性。特别是,化合物9d对正常细胞HFL-1表现出显着的抗增殖活性,IC 50值在8.76μM至9.83μM范围内,细胞毒性较弱,IC 50值为90.9μM,这表明基于异恶唑的of草素杂种是有效的化学修饰以提高东碱的抗癌活性。
