PF-04979064 is a potent and selective PI3K/mTOR dual kinase inhibitor with Kis of 0.13 nM and 1.42 nM for PI3Kα and mTOR, respectively.
PF-04979064 is tested against human class I PI3K isoforms PI3Kα, PI3Kγ, and PI3Kδ, with PI3Kα Ki of 0.13 nM, PI3Kγ Ki of 0.111 nM, and PI3Kδ Ki of 0.122 nM[1].
PF-04979064 is progressed to rat in vivo PK studies and exhibits robust PK profile: Vdss=5.23 L/kg, Cl=19.3 mL/min/kg, T1/2=1.85 h, and F%=61%[1].
