mTOR inhibitor-3 is a remarkably selective mTOR inhibitor with a K_i of 1.5 nM. mTOR inhibitor-3 suppresses mTORC1 and mTORC2 in cellular and in vivo pharmacokinetic (PK)/pharmacodynamic (PD) experiments.

mTOR inhibitor-3 (Compound 12i) inhibits mTOR with a K_i of 1.5 nM, 500-fold selectivity over closely related PI3 kinases. mTOR inhibitor-3 inhibits NCI-PC3 and MCF7neo/Her2 cells proliferation with IC₅₀s of 150 nM and 57 nM, respectively^[2].

mTOR inhibitor-3 (Compound 8h) has high free plasma clearance in both mice (1818 mL/min/kg) and rats (1538 mL/min/kg in rat) ^[1]. mTOR inhibitor-3 (Compounds 12i) is selected for this study due to its potency, selectivity, and favorable mouse PK profile. Plasma levels of mTOR inhibitor-3 6 h following oral administration in PC3 tumor-bearing mice along with the fold decreases of phosphorylated mTORC1 and -2 substrates relative to time-matched vehicle controls. mTOR inhibitor-3 has moderate terminal elimination half-life (t_1/2=1.7 h for mouse(1 mg/kg, iv)). mTOR inhibitor-3 achieves tumor stasis at the highest 200 mg/kg/day dose examined, which appears to also be approaching the limit of tolerability for this molecule^[2].

Mice^[2]
Human prostate cancer NCI-PC3 cells are implanted subcutaneously into the right hind flanks of female NCR nude mice (5×10⁶ cells in 100 μL of Hank’s balanced salt solution). Tumors are monitored until they reach a mean tumor volume of approximately 500 mm³. Then similarly sized tumors are randomly assigned to groups (n=4). Compounds are formulated as suspensions in 0.5% methylcellulose/0.2% Tween 80 (MCT) and dosed orally at 25, 50, and 100 mg/kg (100 μL dose/25 g animal). Tumor and plasma samples are harvested at 1, 6, and 10 h postdose.
