their roles in regulating cell proliferation, differentiation, migration, and survival. Here we report our efforts to develop potent and orally bioavailable PI3K inhibitors for the treatment of cancers. The alkylsulfonamide-containing quinazoline derivatives A1–A18 significantly inhibited PI3Kα, and cell proliferation among HCT-116, MCF-7 and SU-DHL-6 cell lines. The optimal compound A1 displayed potent
磷酸肌醇3-激酶(PI3Ks)被认为是治疗各种癌症的有希望的靶标,因为它们在调节细胞增殖,分化,迁移和存活中的作用。在这里,我们报告了我们为开发有效的和口服可生物利用的PI3K抑制剂来治疗癌症的努力。含烷基磺酰胺的喹唑啉衍生物A1-A18显着抑制PI3Kα,并抑制HCT-116,MCF-7和SU-DHL-6细胞系之间的细胞增殖。最佳化合物A1对PI3Kα(IC 50 = 4.5 nM),PI3Kβ(IC 50 = 4.5 nM),PI3Kγ(IC 50 = 4.5 nM),PI3Kδ(IC 50 = 4.5 nM),并显着抑制HCT-116,MCF-7和SU-DHL-6细胞系的生长,IC 50值分别为0.82 µM,0.99 µM和0.19 µM。蛋白质印迹分析表明,A1以剂量依赖性方式显着抑制AKT S473的磷酸化。此外,在裸鼠HCT-116异种移植模型中,A1在体内剂量为25 mg
