Alpelisib (BYL-719) is a PI3Kα inhibitor (IC50=5 nM) with selective, potent, and oral activity, inhibiting PI3Kβ γ δ with low activity (IC50=250 290 1200 nM). Alpelisib demonstrates antitumor activity and specifically targets PIK3CA mutant tumors.

Alpelisib hydrochloride (BYL-719 hydrochloride) exhibits anticancer properties[1][2]. As a potent and selective PI3Kα inhibitor with high oral bioavailability, it has IC50 values of 5 nM for p110α, 250 nM for p110γ, 290 nM for p110δ, and 1200 nM for p110β, indicating its efficacy in targeting enzymes involved in cancer cell proliferation.

SGK1 inhibitor is an inhibitor of serum- and glucocorticoid-regulated kinase 1 (SGK1) and SGK2. It is selective for SGK1 and SGK2 over SGK3 in the presence of a high concentration of ATP. SGK1 inhibitor prevents phosphorylation of GSK3β in U2OS cells and decreases cell viability in BYL719-insensitive HCC1954 cells when used in combination with the PI3Kα inhibitor BYL719. SGK1 inhibitor reduces tumor growth in an HCC1954 mouse xenograft model when administered in combination with BYL719.
