Product Information
Molecular Weight: 308.34
Formula: C16H16N6O
Purity: ≥ 98%
CAS#: 1092351-67-1
Solubility: DMSO up to 100 mM
Chemical Name: 2-(4-amino-1-isopropyl-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-1H-indol-5-ol
Storage: Powder: 4oC 1 year. DMSO: 4oC 3 month; -20oC 1 year.

Biological Activity:

PP242 is a highly potent, selective and ATP-competitive mTORC1/mTORC2 inhibitor (IC50 = 8 nM). It has > 10 folds selectivity over the other PI-3K family kinases (IC50 0.102 µM, 0.408 µM, 1.27 µM, 1.96 µM and 2.2 μM for p110γ, DNA-PK, p110δ, p110α and p110β, respectively). Except some weak inhibitory activity against PKCα, JAK2, PKCβI, PKCβII and RET (0.05-0.22 µM), PP242 exhibits excellent selectivity over 215 other protein kinases. PP242 differentially inhibits insulin-stimulated phosphorylations of cellular proteins both in vitro and in vivo in a manner distinctly different from that seen in mTORC2-functional knockout SIN1-/- cells or in cultures treated with Rapamycin, which targets only mTORC1, but not mTORC2. Blockage of 4EBP1 T36/T45/S65 phosphorylation by PP242 upon insulin stimulation in primary MEFs correlates well with an enhanced 4EBP1 association with the cap-binding protein eIF4E, resulting in a selective inhibition of cap-dependent, but not cap-independent, protein translation.


How to Use:

  • In vitro: PP242 was used at 2.5 µM concentration in vitro and in cellular assays.
  • In vivo: PP242 was orally dosed to mice at 20-60 mg/kg once per day to inhibit tumor growth, or in combination with Dasatinib, Bortezomib or Imatinib for synergistic activity.
