Description: Omipalisib, also known as GSK2126458, is a small-molecule pyridylsulfonamide inhibitor of phosphatidylinositol 3-kinase (PI3K) with potential antineoplastic activity. PI3K inhibitor GSK2126458 binds to and inhibits PI3K in the PI3K/mTOR signaling pathway, which may trigger the translocation of cytosolic Bax to the mitochondrial outer membrane, increasing mitochondrial membrane permeability and inducing apoptotic cell death. Bax is a member of the proapoptotic Bcl2 family of proteins. PI3K, often overexpressed in cancer cells, plays a crucial role in tumor cell regulation and survival.

Additional Information

GSK2126458 is a highly potent PI3K and mTOR inhibitor. In vivo, GSK2126458 showed anti-tumor activity in both pharmacodynamic and tumor growth efficacy models. GSK2126458 reduced the phosphorylated AKT, p70S6K contents in a dose and time dependent way. The IC50 of GSK2126458 is 2 nM for pAKT in the HCC1954 breast carcinoma cell line. In various human tumor cells, GSK2126458 had a width of inhibitory activity for potent cell growth and induced cell death. Notably, GSK2126458 acted mainly by not induction of apoptosis but cell cycle arrest, particularly in G1-phase
