PP242 has been shown to be a an ATP-competitive mTORC1/mTORC2 (FRAP) inhibitor (IC50 = 8 nM). PP242 is the first selective inhibitor that targets the ATP domain of FRAP. This compound shows selectivity for FRAP over other PI 3K family kinases (IC50 values are 0.102, 0.408, 1.27, 1.96 and 2.2 μM for p110γ, DNA-PK, p110δ, p110α and p110β respectively). Furthermore, PP242 hydrate inhibits both S6K and 4EBP1 phosphorylation this activity displays an overall decrease in cap-dependent protein translation. |
