Background:

Pilaralisib (XL147; SAR245408) is a potent and highly selective class I PI3Ks inhibitor with IC50s of 39 nM, 383 nM, 23 nM and 36 nM for PI3Kα, PI3Kβ, PI3Kγ, and PI3Kδ. PI3Kα|39 nM (IC50)|PI3Kβ|383 nM (IC50)|PI3Kδ|36 nM (IC50)|PI3Kγ|23 nM (IC50)|Vps34|6974 nM (IC50)|DNA-PK|4750 nM (IC50)

Pilaralisib (XL147) displays potent inhibitory activity against Class I PI3K isoforms p110α, p110δ, and p110γ, with IC50s of 39, 36, and 23 nM, respectively. Pilaralisib (XL147) is less potent against the remaining Class I isoform, p110β, with an IC50 value of 383 nM. The IC50 value for inhibition of PI3Kα by Pilaralisib (XL147) is determined at various concentrations of ATP, revealing XL147 to be an ATP-competitive inhibitor with an equilibrium inhibition constant (Ki) value of 42 nM. Pilaralisib (XL147) has relatively weak inhibitory activity toward the class III PI3K vacuolar sorting protein 34 (VPS34; IC50 value of
