    PI3 Kinases are a family of lipid kinases mediating numerous cell processes such as proliferation, migration, and differentiation. The PI3 kinase pathway is often de-regulated in cancer through PI3Kα overexpression, gene amplification, mutations, and PTEN phosphatase deletion. PI3K inhibitors represent therefore an attractive therapeutic modality for cancer treatment. Herein we describe a novel series of PI3K inhibitors sharing a pyrimidine core and showing significant potency against class I PI3 kinases in the biochemical assay and in cells. The discovery, synthesis and SAR of this chemotype are described.
