Torin 1, a member of the pyridinonequinoline class of kinase inhibitors, is a highly selective and ATP-competitive inhibitor of mTOR, with IC50 values between 2 and 10 nM for mTORC1 and mTORC2 both in vitro kinase and whole cell assays. Torin 1 exhibits at least 200-fold selectivity for mTOR over related hVps34 (IC50, 3 μM), PI3Kα (IC50, 1.8 μM), DNA-PK (IC50, 1.0 μM) and ATM (0.6 μM).Torin1 causes cell cycle arrest through a rapamycin-resistant mechanism that is also independent of mTORC2. The compound shows a far greater degree than rapamycin in the suppression of cell growth and proliferation [1]. Torin 1, at a dose of 20 mg/kg, effectively inhibits tumor growth in a U87MG xenograft model and demonstrates good pharmacodynamic inhibition of downstream effectors of mTOR in tumor and peripheral tissues [2].
