Description
PF-4989216 is a novel potent and selective PI3K inhibitor. PF-4989216 inhibits PI3Kalpha (Ki=0.6 nM) and mTOR (Ki=1440 nM).IC50 value: 0.6 nM (Ki, PI3Kalpha), 1440 nM (Ki, mTOR) [1]Target: PI3Kin vitro: PF-4989216inhibits pAKT-S473 with IC50 of 79 nM. [1] PF-4989216 is a potent inhibitor of pan-PI3K isoforms and demonstrates excellent selectivity when screened against more than 100 kinases and 50 non-kinases. PF-4989216 is significantly more potent in SCLCs with PIK3CA mutations than wild-type lines, including cells with PIK3CA copy number gain, providing evidence that SCLCs harboring PIK3CA mutations are more sensitive to inhibition by PF-4989216. [2]vivo: PF-4989216 exhibits good exposure in mice after oral administration and the unbound drug concentration increased with dose, with the ability to maintain approximately 700, 1,900, and 2,100 nM at the 7-hour time point at dosages of 50, 150, and 350 mg/kg, respectively.
