WYE-132 (WYE-125132) is a highly potent, ATP-competitive, and specific mTOR kinase inhibitor (IC₅₀: 0.19±0.07 nM; >5,000-fold selective versus PI3Ks). WYE-132 (WYE-125132) inhibits mTORC1 and mTORC2.

WYE-132 (WYE-125132) potently inhibits recombinant mTOR via an ATP-competitive mechanism. WYE-132 is a potent antiproliferative agent against a panel of cancer cell lines with IC₅₀ values generally in the nanomolar range. In the typical 3-day dose-response studies, WYE-132 exhibits a more profound antiproliferative activity than CCI-779 in MDA361 and other cells, as shown by the sharper inhibition at doses up to 10 μM. Fluorescence-activated cell sorting (FACS) analysis of inhibitor-treated (1 μM, 24 hours) MDA468, PC3MM2, U87MG, A549, and HCT116 cells indicates that WYE-132 elicits a more profound increase in G₁-phase and a reduction in S-phase cells than CCI-779. The WYE-132-induced cell death is evident at 10 and 30 nM (6.2% and 13%, respectively) and is dose dependent, reaching 47% at 1 μM and 59% at 3 μM^[1].

A single i.v. administration of 50 mg/kg WYE-132 (WYE-125132) into tumor-bearing mice leads to suppression of P-S6K(T389) and P-AKT(S473) for at least 8 hours in PC3MM2, MDA361, HCT116, and HT29 tumors, whereas the steady-state level of P-AKT(T308) is not significantly reduced, indicating that the antitumor efficacy of WYE-132 under such dosing regimens reflects the suppression of mTOR rather than PI3K. Oral administration of WYE-132 causes dose-dependent tumor growth delay in the PI3K/mTOR- and HER2-hyperactive MDA361 tumors with significant antitumor activity at 5 mg/kg, which correlates with a suppression P-S6 and P-AKT(S473) but not P-AKT(T308). An optimal dose of 50 mg/kg WYE-132 induces a substantial regression of large MDA361 tumors. WYE-132 also causes a potent and substantial tumor growth delay in the PTEN-null U87MG glioma^[1].

Mice^[1]
For mTOR biomarker studies, various tumors (400 mm³) grown s.c. in female nude mice are dosed by a single i.v. or oral injection with vehicle or WYE-125132 formulated in 5% ethanol, 2% Tween 80, and 5% polyethylene glycol-400. Tumor lysates are prepared and immunoblotted. For efficacy studies, nude mice bearing U87MG, MDA361, H1975, A549, A498, or 786-O tumors are staged and randomized into treatment groups (n=10). Mice are dosed orally with vehicle or WYE-125132 following qd x5 cycle regimen (5 d on, 2 d off) for up to four cycles. Temsirolimus/CCI-779 is formulated as WYE-132 and dosed i.v. once weekly. Bevacizumab is formulated in PBS and dosed i.p. via its clinical regimen (200 μg/mouse; once weekly). Tumor growth is monitored and analyzed.
