Designed and synthesized novel homopiperazine linked imidazo[1,2-a]pyrimidine derivatives (10a–i, 11a–g, 12), and evaluated them for their in vitro cytotoxicity against HeLa cells (cervical cancer), A549 cells (lung cancer) cells, by MTT assay. Compound 12 (IC50 = 4.14 µM) and compound 10c (IC50 = 5.98 µM) were found to be 2.5 fold, and 1.74 fold more potent when compared with standard Etoposide (IC50 = 10
设计并合成了新的高哌嗪连接的咪唑并[1,2- a ]嘧啶衍生物(10a–i,11a–g,12),并评估了它们对HeLa细胞(宫颈癌),A549细胞(肺癌)的体外细胞毒性细胞,通过MTT测定。 与标准依托泊苷(IC 50 = 10.44 µM)相比,发现针对A549(肺癌细胞)的化合物12(IC 50 = 4.14 µM)和化合物10c(IC 50 = 5.98 µM)的效力是2.5倍,效力是1.74倍。)。还发现化合物12对DU145的效力为1.57倍和1.13倍(IC 50 与依托泊苷(DU145,IC 50 = 9.8 µM; HeLa,IC 50 = 7.43 µM)相比,分别为 = 6.24 µM)和HeLa(IC 50 = 6.54 µM)。 发现 针对HeLa细胞系,化合物10f(IC 50 = 6.12 µM)的效力比依托泊苷(IC 50 = 7.43 µM)高1.31倍。
