Biological Activity

Idelalisib (CAL-101, GS-1101) is a potent, selective inhibitor of PI3K p110δ with IC50 of 2.5 nM, 40- to 300-fold selectivity over other class I PI3Ks (p110α/βγ, IC50=820/565/89nM), and 400- to 4000-fold over C2β, hVPS34, DNA-PK, and mTOR.
Idelalisib (CAL-101, GS-1101) blocks FcϵRI p110δ-mediated CD63 expression in basophils with an EC50 of 8 nM.
Idelalisib (CAL-101, GS-1101) blocks constitutive PI3K signaling, resulting in decreased phosphorylation of Akt and other downstream effectors, an increase in PARP and caspase cleavage and an induction of apoptosis in multiple B-cell malignancies.
