A series of new coumarin-containing compounds 3a-l and 4a-c was designed and synthesized based on the chalcone-type 4-amino-5-cinnamoylthiazole scaffold 2, and screened for their in vitro anticancer and antioxidant activities. Representatively, the 2-thiomorpholinothiazole derivative 3k with IC50 values of 7.5–16.9 μg/ml demonstrated good cytotoxic effects against tested cell lines MCF-7, HepG2 and
基于查尔酮型4-氨基-5-肉桂酸噻唑支架2,设计合成了一系列新的含香豆素的化合物3a-1和4a-c,并对其体外抗癌和抗氧化活性进行了筛选。代表性的是2-硫吗啉代噻唑衍生物3k(IC 50)7.5-16.9μg/ ml的值显示出对测试的MCF-7,HepG2和SW480细胞系的良好细胞毒性作用。通过流式细胞术分析的进一步研究证实,该化合物在MCF-7细胞中诱导凋亡细胞死亡,并在细胞周期中引起G1期阻滞。此外,如DPPH和FRAP分析所研究的那样,大多数化合物具有清除自由基和还原三价铁的内在潜力。
