Abstract

In present study, a series of N-(2-methoxy-5-(3-substituted quinazolin-4(3H)-one-6-yl)-pyridin-3-yl)phenylsulfonamide were synthesized. Their antiproliferative activities in vitro were evaluated via MTT assay against HCT116 and MCF-7 Cancer cell lines. The SAR of title compounds was discussed. The compounds (S)-C5 and (S)-C8 displayed potent inhibitory activity against PI3Ks and mTOR, especially against PI3Kα. In addition, compound (S)-C5 can efficaciously inhibit tumor growth in a mice S-180 model. These findings suggest that our designed compounds can serve as potent PI3K inhibitors and effective Anticancer agents.
