Chemical Structure

Biological activities

PKI-402 is a selective, reversible and ATP-competitive inhibitor of class I phosphatidylinositol 3-kinases (PI3K). PKI-402 inhibits class I PI3Kα, PI3Kβ, PI3Kδ, and PI3Kγ with IC50 of 2, 7, 14 and 16 nM, respectively. PKI-402 also inhibits PI3K-α mutants E545K and H1047R, and mTOR with IC50 of 3, 3 and 3 nM, respectively. [1] In vitro, PKI-402 inhibits breast cell lines MDA-MB-361, MDA-MB-468, T47D and BT474 with IC50 of 6, 9, 13 and 26 nM, respectively. PKI-402 inhibits the growth of human tumor cell lines derived from breast, brain (glioma), pancreas, and non??mall cell lung cancer tissue. PKI-402 suppresses phosphorylation of PI3K and mTOR effector proteins. In vivo, PKI-587 inhibits tumor growth in breast (MDA-MB-361, BT474), colon (HCT116), lung (H1975), and glioma (U87MG) xenograft models. [2]
