T133
T133 is an orally active ATP-competitive mTOR inhibitor with an IC50 of 0.34 nM and a Ki of 0.17 nM. T133 suppresses phosphorylation of AKT, S6K1, and 4EBP1. T133 inhibits cancer cell proliferation and migration, induces apoptosis, cell cycle arrest, and autophagy. T133 exhibits dose-dependent antitumor efficacy in xenograft mouse models. T133 can be used for the research of cancer, such as gastric cancer and lung cancer.

T133 (Compound 51) potently inhibits recombinant mTOR kinase activity with an IC50 of 0.34 nM and a Ki of 0.17 nM[1].
T133 exhibits over 10-fold selectivity for mTOR over most class I PI3K isoforms, with a PI3Kδ Ki of 1.8 nM, PI3Kγ Ki of 4.9 nM, PI3Kα Ki of 47 nM, and PI3Kβ Ki of 125 nM[1].
T133 (72 h) potently inhibits the proliferation of HGC-27, NCI-H1299, and T-47D cancer cells with IC50 values of 0.82 μM, 1.22 μM, and 0.28 μM respectively[1].
T133 (1-2.5 μM; 16 h) significantly inhibits the migration of HGC-27 gastric cancer cells after 16 h of treatment[1].
T133 (0.3-100 μM; 2 h, 24 h) dose-dependently inhibits the PI3K/AKT/mTOR signaling pathway and induces apoptosis in HGC-27, NCI-H1299, and T-47D cancer cells after 2 h and 24 h of treatment[1].
T133 (20-100 nM; 48 h) induces autophagy in HGC-27 gastric cancer cells after 48 h of treatment[1].
T133 (100-500 nM; 24 h) arrests HGC-27 gastric cancer cells in the G1 phase of the cell cycle after 24 h of treatment[1].
