PI4K

PIK 93 selectively inhibits the type III PI 4-kinase enzyme, and small interfering RNA-mediated down-regulation of the individual PI 4-kinase enzymes.

NVP-BKM120 Hydrochloride is a selective PI3K inhibitor of p110α/β/δ/γ with IC50 of 52 nM/166 nM/116 nM/262 nM, respectively. Reduced potency against VPS34, mTOR, DNA-PK, with little activity to PI4Kβ.

PI4KIIIbeta-IN-9 is a potent PI4KIIIbeta inhibitor (IC50 of 7 nM) and is >140-fold selective over PI3Kgamma and >20-fold selective over PI3Kδ, and shows no inhibition of vps34 at concentrations up to 20 uM.

BQR-695, also known as NVP-BQR695, is a PI4KIIIβ inhibitor with IC50s of 80 and 3.5 nM for human PI4KIIIβ and Plasmodium variant of PI4KIIIβ, respectively.
