Product Description

GSK2126458 is an orally available, pyridazine-quinoline-based inhibitor of of p110?, p110?, p110?, p110?, mTORC1, and mTORC2 with Ki of 0.019 nM, 0.13 nM, 0.024 nM, 0.06 nM, 0.18 nM and 0.3 nM, respectively. [1] In mechanistic assays, GSK2126458 induced significant reduction in levels of pAKT-S473 (0.41 nM in T47D and 0.18 nM in BT474). It also inhibits phosphorylation of AKT-T308 and p70S6K at low nanomolar concentrations. Induction of caspase 3 and 7 activity suggests that GSK2126458 utilizes apoptosis as a mechanism for cell death. [2]

Combination of GSK2126458 with B-Raf inhibitor GSK2118436 (Dabrafenib) enhanced cell growth inhibition and decreased S6 ribosomal protein phosphorylation in NRAS and MEK mutant clones. Combination of GSK2126458 and MEK inhibitor GSK1120212 (trametinib) has been studied in Phase I clinical trials. [3]
