idelalisib | 5-fluoro-3-phenyl-2-[(1S)-1-(9H-purin-6-ylamino)propyl]quinazolin-4(3H)-one, a PI3Kdelta inhibitor used to treat hematological malignancies. The inhibitor idelalisib is selective, noncovalent, reversible, and ATP-competitive. The compound binds reversibly and noncovalently to the p110delta subunit of the kinase, analysis of binding interactions that confer the potency and selectivity of idelalisib, overview. Idelalisib is a propeller-shaped inhibitor | Homo sapiens |
