What is GSK2636771?
Description
GSK2636771 is a potent, orally bioavailable, adenosine triphosphate-competitive, selective inhibitor of PI3Kβ with an apparent Ki value of 0.89 nmol/L (IC50 = 5.2 nmol/L), >900-fold selectivity over p110α and p110γ, and >10-fold selectivity over p110δ isoforms, while sparing other PI3K superfamily kinases[1-2].
The Uses of GSK2636771
GSK2636771 is a potent, orally bioavailable, PI3Kβ-selective inhibitor, sensitive to PTEN null cell lines.
in vitro
GSK-2636771 shows selectively inhibitory activity in PTEN null cell lines (human prostate adenocarcinoma PC-3 and breast cancer HCC70) with EC50 of 36 nM and 72 nM, respectively. GSK2636771 significantly decreases cell viability in p110β-reliant PTEN-deficient PC3 prostate and BT549 and HCC70 breast cancer cell lines. It leads to a marked decrease of AKT phosphorylation only in the control prostate and breast cancer cell lines.
