Description

General description

A cell-permeable pyridinylfuranopyrimidine compound that acts as a potent and ATP-competitive inhibitor of DNA-PK, PI3-K, and mTOR (IC₅₀ = 2, 8, 88, 48, 150, 26, 20, and 83 nM for DNA-PK, p110α, p110β, p110δ, p110γ, PI3-KC2β, mTORC1, and mTORC2, respectively). It inhibits ATR and ATM only at much higher concentrations (IC₅₀ = 850 and 920 nM, respectively) and exhibits little activity towards a panel of more than 40 other kinases even at concentrations as high as 10 µM. Shown to effectively block PI3-K/Akt signaling and cell proliferation in glioma cell lines both in vitro and in vivo. A 10 mM (2 mg/574 µl) solution of PI-103 (Cat. No. 528101) in DMSO is also available.
