A series of quinoline-chalcone hybrids was designed as potential anti-cancer agents, synthesized and evaluated. Different cytotoxic assays revealed that compounds experienced promising activity. Compounds 9i and 9j were the most potent against all the cell lines tested with IC50 = 1.91-5.29 µM against A549 and K-562 cells. Mechanistically, 9i and 9j induced G2/M cell cycle arrest and apoptosis in both
设计了一系列喹啉-查耳酮杂化物作为潜在的抗癌药,进行了合成和评估。不同的细胞毒性试验表明,化合物具有良好的活性。化合物9i和9j对所有测试的A549和K-562细胞的IC50 = 1.91-5.29 µM的细胞系最有效。从机理上讲,9i和9j诱导了A549和K562细胞的G2 / M细胞周期停滞和凋亡。此外,当针对两种提及的化合物进行测试时,所有PI3K亚型均被非选择性抑制,IC50为52-473 nM,其中9i对PI3K-γ最有效(IC50 = 52 nM)。9i和9j的对接显示可能在PI3K-γ同工型的活性位点与基本缬氨酸残基形成H键。同时,Western印迹分析显示9i和9j抑制了PI3K,Akt,mTOR,以及A549和K562细胞中的GSK-3β,提示阻断PI3K / Akt / mTOR途径与上述抗肿瘤活性相关。总之,我们的发现通过抑制PI3K / Akt / mTOR途径,支
