WYE-354 (WYE 354) is a novel, potent, specific, cell-permeable and ATP-competitive mTOR (mammalian target of rapamycin) inhibitor with potential anticancer/antitumor activity. With an IC50 of 5 nM, it inhibits mTOR.
| Targets |
mTOR (IC50 = 5 nM); mTORC1; mTORC2; PI3K alpha (IC50 = 1.89 μM); PI3K gamma (IC50 = 7.37 μM); Autophagy;

| ln Vitro |
WYE-354 inhibits recombinant mTOR enzyme in the DELFIA assay for measuring His6-S6K1 T389 phosphorylation with an IC50 of 5 nM[1]. MTS assay is used to evaluate cell viability. WYE-354 is applied to the G-415 and TGBC-2TKB cell lines at increasing concentrations for 24, 48, and 72 hours. After a 24-hour exposure, WYE-354 significantly lowers cell viability in both tested cell lines starting at a 1 M concentration (P<0.001). Except for the TGBC-2TKB cell line after 72 hours of treatment, no reduction in cell viability is seen at a dose of 100 nM[2].

| ln Vivo |
In xenograft GBC tumor models, the influence of Rapamycin and WYE-354 on tumor growth is assessed. NOD-SCID mice receive subcutaneous xenotransplantations of 2 106 or 5 106 cells of G-415 or TGBC2TKB, respectively. Rapamycin or WYE354 are administered to the mice when tumors reach an average volume of 100 mm3. While WYE-354 is given daily intravenously at a dose of 50 mg/kg for five days, rapamycin is given intravenously at a concentration of 10 mg/kg, five days a week for three weeks. 30 days after the start of the treatments, mice are sacrificed, and an autopsy is carried out, including the removal of the entire tumor area. WYE-354-treated mice show reductions in tumor weight of 82.9% and 45.5% (P<0.01; ns) , respectively, as well as average tumor size reductions of 68.6% and 52.4% (P<0.01; P<0.01).

| Enzyme Assay |
The assays are performed in 96-well plates for 2 hours at room temperature in 25 μL containing 6 nM Flag-TOR(3.5), 1 μM His6-S6K, and 100 μM ATP. The assays are performed and detected by DELFIA employing the Eu-phospho-p70S6K T389 antibody. For inhibitor versus ATP matrix competition, mTOR kinase reactions are carried out with varying concentrations of ATP (0, 25, 50 100, 200, 400, and 800 μM) in combination with varying concentrations of WYE-354. The assays contained 12 nM Flag-TOR(3.5), 1 μM His-S6K, and are incubated for 30 min. The assay results are similarly detected by DELFIA and processed for generation of double-reciprocal plots.

| Cell Assay |
Cells (Tumor cell lines including MDA-MB-361, MDA-MB-231, MDA-MB-468, LNCap, DU145, A498, and HCT116) are plated in 96-well plates at 1000 to 3000 cells per well for 24 hours, treated with DMSO or varying concentrations of WYE-354. Viable cell densities are determined 72 hours later by MTS assay employing a CellTiter 96 kit. The effect of each treatment is calculated as percent of control growth relative to the DMSO-treated cells grown in the same culture plate. Inhibitor dose response curves are plotted for determination of IC50 values.
WYE-354 also inhibits several PI3Ks at micromolar levels. In HEK293 cells, WYE-354 (0.2 μM–5 μM) effectively inhibits both mTORC1 and mTORC2. WYE-354 (0.3 μM–10 μM) significantly blocks mTOR signaling and Akt activation in U87MG and MDA361 cells. Furthermore, WYE-354 potently inhibits proliferation in tumor cell lines including MDA-MB-361, MDA-MB-231, MDA-MB-468, LNCap, A498, and HCT116, with IC50 values ranging from 0.28 μM to 2.3 μM. The apoptosis induced by WYE-354 is accompanied by G1 cell cycle arrest and caspases activation. In endothelial HUVEC cells, WYE-354 (10 nM–1 μM) also inhibits both mTORC1 and mTORC2 signaling, as revealed by dephosphorylation of S6 ribosomal protein and Akt, respectively. Furthermore, WYE-354 (10 nM–1 μM) activates mitogen-activated protein kinase (MAPK) signaling, which may be due to its inhibition of mTORC1.

| Animal Protocol |
Mice[2]
8 to 12-week- old NOD-SCID mice are subcutaneously injected in one flank with either 2×106 or 5×106 cells of G-415 or TGBC2TKB, respectively, and re-suspended in 200 μL of PBS with 30% of Matrigel. When the average tumor reach 100 mm3, mice are randomly separated into four groups and treated with Rapamycin or WYE-354 and its respective vehicles. Rapamycin is administered at a daily intraperitoneal (i.p) dose of 10 mg/kg for 5 days per week for 3 weeks, while WYE-354 is administrated at a daily i.p dose of 50 mg/kg for 5 days. Tumor volumes are estimated twice a week. |
