The present study involves design and synthesis of five series of 6-bromo-2-(pyridin-3-yl)-4-substituted quinazolines 9a-l, 11a-e, 13a-c, 14a-f and 15a-e. Candidates 9a-l and 11a-e were evaluated for their EGFR and HER2 inhibitory activity compared to Lapatinib. Compounds 9b, 9d, 9f, 11b and 11c were further screened for their in vitro cytotoxicity against two human breast cancer cell lines: AU-565
本研究涉及设计和合成五个系列的 6-bromo-2-(pyridin-3-yl)-4-取代的喹唑啉9a-l、11a-e、13a-c、14a-f和15a-e。与拉帕替尼相比,评估了候选者9a-l和11a-e的 EGFR 和 HER2 抑制活性。除了正常乳腺细胞系MCF10A之外,化合物9b、9d、9f、11b和11c针对两种人乳腺癌细胞系:AU-565和MDA-MB-231进一步筛选了它们的体外细胞毒性。化合物9d显示相对于拉帕替尼(IC 50 = 0.48 µM)对 AU-565 细胞系 (IC 50 = 1.54 µM)具有显着的细胞毒性功效 ,而化合物9d和11c对 MDA-MB-231 显示出优异的细胞毒性 (IC 50 = 2.67和 1.75 µM)与拉帕替尼(IC 50 = 9.29 µM)相比。此外,与索拉非尼相比,测试了化合物13a-c、13a-c、14a-f和15a-e的
