mTOR Inhibitor XII, Torin2-Calbiochem

C₂₄H₁₅F₃N₄O

432.40

A Torin1 (Cat. No. 475991) structural analog that acts as a cell-permeable, potent, ATP-competitive inhibitor against DNA-PK and mTOR (IC₅₀ = 0.5 and 2.81 nM, respectively). Comparing to Torin1, Torin2 displays enhanced inhibitory potency against PI 4-Kβ (IC₅₀ = 18.3 nM) and PI 3-K (IC₅₀ =4.68, 5.67, 8.58, 17.5, 24.5, and 28.1 nM, respectively, against P110α/P85α, P110γ, hVPS34, P110δ/P85α, C2β, C2α, respectively), while being more effective in inhibiting S6K1 Thr389 phosphorylation in MEF cultures (IC₅₀ = 0.25 nM vs 2 nM, respectively, for Torin2 and Torin1) in vitro and displaying much improved oral bioavailability in mice (C_max (ng/mL) /T_1/2 (h) = 3968/0.72 and 223/0.79, respectively, for Torin2 and Torin1; 10 /mg/kg p.o.) in vivo.
