2‐isocamphanyl thiosemicarbazone derivatives were synthesized and characterized by 1H NMR, 13C NMR, and HRMS. In in vitro anticancer activity, most derivatives showed considerable cytotoxic activity against four cancer cell lines (RPMI‐8226, A549, MDA‐MB‐231, and HepG2 cancer cells) and showed low toxicity against human gastric mucosal cells (GES‐1). Among them, compound 4h exhibited excellent antitumor activity
合成了一系列新颖的2-异樟脑硫代半碳酰胺衍生物,并通过1 H NMR,13 C NMR和HRMS进行了表征。在体外抗癌活性中,大多数衍生物对四种癌细胞系(RPMI-8226,A549,MDA-MB-231和HepG2癌细胞)表现出相当大的细胞毒活性,对人胃粘膜细胞(GES-1)的毒性低。其中,化合物4h对测试的癌细胞表现出优异的抗肿瘤活性,MDA-MB-231,RPMI-8226,A549和HepG2的IC 50值分别为0.4、1.1、1.6和1.7μM。此外,机理研究表明,化合物4h 通过增强活性氧水平,诱导线粒体膜电位降低并影响Bax,Bcl-2,caspase-3和caspase-9的表达来诱导MDA-MB-231细胞凋亡。
