Due to the increasing evidence linking the PI3Kγ pathway to various disease states, PI3Kγ is becoming an important target for cancer treatment. Herein we designed and synthesized a novel series of N, 4-diphenylpyrimidin-2-amine derivatives with low CDOCKER_INTERACTION_ENERGY and then evaluated their PI3Kγ in vitro inhibitory activities and in vitro antiproliferation assays against four human cancer cells. Among the ...
