Phosphoinositide 3-kinases (PI3Ks) are regarded as promising targets for treatment of various cancers due to 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 inhibitory activity against PI3Kα (IC50 = 4.5 nM), PI3Kβ (IC50 = 4.5 nM), PI3Kγ (IC50 = 4.5 nM), PI3Kδ (IC50 = 4.5 nM) and significantly inhibited the growth of HCT-116, MCF-7 and SU-DHL-6 cell lines with IC50 values of 0.82 μM, 0.99 μM and 0.19 μM, respectively. Western blot analysis demonstrated A1 significantly suppressed the phosphorylation of AKTS473 in a dose-dependent manner. Furthermore, A1 could markedly inhibit cancer growth at the dose of 25 mg/kg in nude mouse HCT-116 xenograft model in vivo without causing significant weight loss or toxicity.

Abstract A novel series of 4-alkynyl-quinoline derivatives were designed, synthesized and biologically evaluated for their PI3Kα inhibitory activities and anti-proliferative effects against two cancer cell lines PC-3 and HCT-116. Most of them showed potent PI3Kα inhibitory activities with IC50 values at low nanomolar level and good to excellent anti-proliferative effects against both cell lines. Among them, compound 15d, the most potent one, was selected for further biological evaluation. As a result, 15d displayed strong inhibitory activity against other class I PI3K isoforms (PI3Kβ, PI3Kγ and PI3Kδ) and mTOR with an acceptable kinase selectivity profile. Moreover, the western blot assay indicated that the phosphorylation of Akt, another downstream effector of PI3K, can be remarkably suppressed by 15d at cellular level. All these experimental results suggested that 15d is a potent PI3K/mTOR dual inhibitor and could serve as a promising lead compound for the development of anticancer agents.
