byl719

Alpelisib (BYL-719) 是一种 PI3Kα 抑制剂 (IC50=5 nM)，具有选择性、有效性和口服活性。Alpelisib 以较低活性抑制 PI3Kβ γ δ (IC50=250 290 1200 nM)。Alpelisib 具有抗肿瘤活性，对 PIK3CA 突变肿瘤具有靶向性。

Alpelisib hydrochloride (BYL-719 hydrochloride) shows antineoplastic activity[1][2]. Alpelisib hydrochloride (BYL-719 hydrochloride) is a potent, orally active, and selective PI3Kα inhibitor with IC50s of 5 nM, 250 nM, 290 nM and 1200 nM for p110α, p110γ,

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.
