Description

Background Information:

XL-147 (Pilaralisib) is a potent, selective and orally bioavailable ATP-competitive small molecule inhibitor targeting pan-class I phosphatidylinositol 3 kinase (PI3K) family with IC50 values of 39, 383, 36 and 23 nM for p110 α, β, δ and γ isoforms, and is highly selective over mTOR (IC50 > 15000 nM), VPS34 (IC50 = 6975 nM), DNAPK (IC50 = 4750 nM). It is currently in clinical trials for cancer treatment.
