Abstract A new set of quinoline and isatine derivatives were synthesized as antiangiogenic VEGFR-2 inhibitors. On a biological level, the in vitro ability of the obtained candidates to inhibit VEGFR-2 was found to be strong with IC50 values in the range of 76.64–175.50 nM. To investigate the cytotoxicity and safety, all compounds were tested against a panel of four cancer cell lines (A549, Caco2, HepG2
抽象的 合成了一组新的喹啉和靛碱衍生物作为抗血管生成 VEGFR-2 抑制剂。在生物学水平上,所获得的候选物抑制 VEGFR-2 的体外能力很强,IC 50值在 76.64–175.50 nM 范围内。为了研究细胞毒性和安全性,所有化合物都针对四种癌细胞系(A549、Caco2、HepG2 和 MDA)以及两种正常细胞系(Vero 和 WI-38)进行了测试。有趣的是,化合物12对A549、Caco2和MDA表现出明显的细胞毒性,IC 50值分别为5.40、0.58和0.94 µM。这些结果比阿霉素(分别为 0.70、0.82 和 0.90 µM)更好且可比,对 Caco2 细胞系的选择性指数高出三倍以上。低浓度的化合物9可以阻止癌细胞的愈合。此外,除了略微上调 TGF-β 基因外,还通过显着下调 Bcl2、Bcl-xl 和 Survivin 的表达,证明了该化合物诱导 Caco-2 程
