Overview

Information

Omipalisib (GSK2126458, GSK458) is a highly selective and potent inhibitor ofp110α/β/δ/γ, mTORC1/2 withKiof 0.019 nM/0.13 nM/0.024 nM/0.06 nM and 0.18 nM/0.3 nM in cell-free assays, respectively. Omipalisib inducesautophagy. Phase 1.
In vitro

GSK2126458 potently inhibits the activity of common activating mutants of p110α (E542K, E545K, and H1047R) found in human cancer with Ki of 8 pM, 8 pM and 9 pM, respectively. GSK2126458 causes a significant reduction in the levels of pAkt-S473 with remarkable potency in T47D and BT474 cells with IC50 of 0.41 nM and 0.18 nM, respectively. Furthermore, GSK2126458 leads to a G1 cell cycle arrest and produces the inhibitory effect on cell proliferation in a large panel of cell lines, including T47D and BT474 breast cancer lines with IC50 of 3 nM and 2.4 nM, respectively.

In vivo

In a BT474 human tumor xenograft model, GSK2126458 treatment results in a dose-dependent reduction in pAkt-S473 levels, and exhibited dose-dependent tumor growth inhibition at a low dose of 300 μg /kg. Besides, GSK2126458 shows low blood clearance and good oral bioavailability in four preclinical species (mouse, rat, dog, and monkey).
