A series of novel quinoline–chalcone derivatives were designed, synthesized, and evaluated for their antiproliferative activity. Among them, compound 24d exhibited the most potent activity with IC50 values ranging from 0.009 to 0.016 μM in a panel of cancer cell lines. Compound 24d also displayed a good safety profile with an LD50 value of 665.62 mg/kg by intravenous injection, and its hydrochloride
设计,合成并评估了一系列新颖的喹啉-查尔酮衍生物的抗增殖活性。其中,化合物24d在一组癌细胞系中表现出最有效的活性,IC 50值为0.009至0.016μM。化合物24d还显示出良好的安全性,通过静脉注射的LD 50值为665.62 mg / kg,并且其盐酸盐24d-HCl在H22异种移植模型中可显着抑制肿瘤生长,而没有可观察到的毒性作用,比CA更有效-4。机制研究表明24d结合到微管蛋白的秋水仙碱位点,使细胞周期停滞在G2 / M期,诱导凋亡,线粒体去极化,并诱导K562细胞产生氧化性应激。此外,24d具有有效的体外抗转移作用以及体外和体内抗血管活性。总的来说,我们的发现表明24d作为一种有效且安全的抗癌药物,值得进一步研究。
