and evaluated for their anticancer potential against human breast MCF-7, lung carcinoma A549 and hepatoma Hep3B cancer cell lines. Compound 10c was the most active against MCF-7 with IC50 value of 4.72 µM, while compound 12b was the most active against A549 and Hep3B cell lines. Moreover, kinases/COXs inhibition and apoptosis induction were suggested as potential molecular mechanisms for the anticancer
已经合成了一组新的吡咯烷嗪-5-羧酰胺,并评估了它们对人乳腺MCF-7,肺癌A549和肝癌Hep3B癌细胞系的抗癌潜力。化合物10c对MCF-7最有活性,IC 50值为4.72 µM,而化合物12b对A549和Hep3B细胞系最有活性。此外,激酶/ COXs抑制和凋亡诱导被认为是潜在的分子机制,基于其结构特征的新型吡咯嗪的抗癌活性。新化合物显着抑制具有IC 50的COX-1和COX-2与COX-1相比,COX-2的选择性高,分别在5.78–11.96 µM和0.1–0.78 µM的范围内。有趣的是,MTT分析中最有效的化合物即化合物12b对COX-2表现出高抑制活性,选择性指数(COX-1 / COX-2)>100。同时,化合物12b对6种激酶的抑制作用表现为弱至中度抑制与伊马替尼相比,%(7–20%)(抑制%= 1–38%)。细胞周期分析,膜联蛋白V PI / FITC凋亡测定和caspase-3
