class of imidazo[2,1‐b]thiazole chalcone derivatives were synthesized and evaluated for their anticancer activity. These chalcone derivatives show promising activity, with log GI50 values ranging from −7.51 to −4.00. The detailed biological aspects of these derivatives toward the MCF‐7 cell line were studied. Interestingly, these chalcone derivatives induced G0/G1‐phase cell‐cycle arrest, down‐regulation
合成了新型的咪唑并[2,1– b ]噻唑查尔酮衍生物,并对其抗癌活性进行了评估。这些查耳酮衍生物显示出令人鼓舞的活性,log GI 50值为-7.51至-4.00。研究了这些衍生物对MCF-7细胞系的详细生物学特性。有趣的是,这些查耳酮衍生物诱导了G 0 / G 1期细胞周期停滞,下调了G 1。细胞周期调节蛋白,如细胞周期蛋白D1和细胞周期蛋白E1,以及CDK4的上调。此外,这些化合物还引发了细胞凋亡的特征性特征,例如p53,p21和p27水平的升高,NF-κB的抑制以及caspase-9的上调。这些查耳酮衍生物之一3 d可能非常适合单独或与现有疗法组合进行详细的生物学研究。
