Torin 1 is an ATP-competitive inhibitor of the mammalian target of rapamycin (mTOR), inhibiting the mTOR complexes mTORC1 and mTORC2 with IC50 values of 2 and 10 nM respectively
It is selective for mTOR versus a panel of over 400 other kinases screened at 10 μM (Thoreen et al.; Liu et al.)
Inhibits tumor growth, likely through a cytostatic rather than cytotoxic mechanism, in a U87MG PTEN-null glioblastoma mouse xenograft model (Liu et al.)
Hinders growth, motility, invasion, and survival of primary colon cancer stem-like cells in vitro, and suppresses tumor growth but does not affect normal colon stem cells in xenografts (Francipane & Lagasse)
