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) is a potent PI3Kα inhibitor (IC₅₀ = 5 nM) with selectivity and oral bioavailability, exhibiting activity against PI3Kβ/γ/δ that is dozens of times weaker than against PI3Kα (IC₅₀ = 250/290/1200 nM). Alpelisib exhibits targeting activity against PIK3CA-mutated tumors and may be utilized in cancer research.

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.
