Alpelisib (also known as BYL719), is a potent and selective phosphatidylinositol-3 kinase α inhibitor. It inhibits P110α, p110β, p110δ, and p110g with IC₅₀ values of 5 nM, 1.2 µM, 0.29 µM and 0.25 µM, respectively, in biochemical assays. It inhibits the Akt phosphorylation with IC₅₀ values of 74 nM in Rat1-myr-p110α cells, 2.2 µM in Rat1-myr-p110β cells, and 1.2 µM in Rat1-myr-p110δ cells.
