WYE-687 is an ATP-competitive mTOR inhibitor with an IC₅₀ of 7 nM. WYE-687 concurrently inhibits activation of mTORC1 and mTORC2. WYE-687 also inhibits PI3Kα and PI3Kγ with IC₅₀s of 81 nM and 3.11 μM, respectively.

In the DELFIA measuring His6-S6K1 T389 phosphorylation, WYE-687 inhibits recombinant mTOR enzyme with an IC₅₀ of 7 nM^[1]. HL-60 AML cells are treated with applied concentrations of WYE-687 (33-1000 nM), MTT cell survival assay results demonstrate that WYE-687 potently inhibits HL-60 cell survival in a dose-dependent manner. A time dependent response by WYE-687 is also noticed. The number of dead (“trypan blue” positive) HL-60 cells is significantly increased following applied WYE-687 (100-1000 nM) treatment. At the meantime, HL-60 cell proliferation, tested by [H³] Thymidine integration assay, is also inhibited by the WYE-687. Results show that WYE-687 is also antisurvival (“cytotoxic”) to the other AML cell lines: U937, THP-1 and AML-193^[2].

U937 cells are inoculated into the flanks of SCID/beige mice. When xenografted tumors reach a volume around 100 mm³, mice are orally administrated with either vehicle control (5% ethanol, 2% Tween 80, and 5% polyethylene glycol-400) or WYE-687 (5 or 25 mg/kg) daily for a total of 7 days. The WYE-687 regimen utilized in this study is based on preexperimental results and related studies. WYE-687 administration (5 or 25 mg/kg, daily) significantly inhibits U937 xenograft tumor growth in SCID mice, and the in vivo activity by WYE-687 is dose-dependent. At day 15, the 5 mg/kg WYE-687-treated tumors and 25 mg/kg WYE-687-treated tumors are 50% and 75% smaller than the vehicle control tumors, respectively. Tumor weights of WYE-687-treated mice are also significantly lower than that of vehicle group. Oral administration of WYE-687 potently inhibits U937 leukemic xenograft tumor growth in SCID mice, without causing significant toxicities^[2].

The routine inhibitor assays are performed in 96-well plates for 2 h at room temperature in 25 μL containing 6 nM Flag-TOR(3.5) (estimated 5-10% purity), 1 μM His6-S6K and 100 μM ATP. The assays are performed and detected by DELFIA employing the Euphospho-p70S6K T389 antibody. Some assays employ a commercially purchased batch of mTOR. 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 inhibitor. The assays contain 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^[1].

Acute myeloid leukemia (AML) cells/progenitor cells are seeded at a density of 1 ×10⁵ cells/well in 0.5 mL DMEM containing 10% FBS onto the 48-well tissue culture plates, cells are treated with indicated concentrations of WYE-687 (33-1000 nM) with the presence of 1 mCi/mL of tritiated thymidine. To determine [H³] thymidine incorporation, cells are washed, the DNA is precipitated with cold 10% trichloroacetic acid (TCA), solubilized with 1.0 M sodium hydroxide, and aliquots are counted by liquid-scintillation spectrometry. The value of treatment group is normalized to that of untreated control group^[2].

Mice^[2]
U937 cells (2×10⁶ cells/mice, suspended in 100 mL of culture medium) are injected into the right flanks of 6-week-old male CB17 severe combined immunodeficient (SCID)/beige mice, and cells are allowed to grow to palpable tumors. When tumors reach a volume around 100 mm³, animals are randomly assigned to three groups: WYE-687 (5 mg/kg body weight), WYE- 687 (25 mg/kg body weight) or the vehicle control (5% ethanol, 2% Tween 80, and 5% polyethylene glycol-400). WYE-687 and vehicle control are freshly prepared, and given by oral gavage daily for 7 consecutive days. Tumor sizes are measured. At the end of experiment, the animals are killed, and the tumors are removed and weighted.

WYE-354 is an ATP-competitive mTOR inhibitor with an IC₅₀ of 5 nM. WYE-354 also inhibits PI3Kα and PI3Kγ with IC₅₀s of 1.89 μM and 7.37 μM, respectively. WYE-354 inhibits both mTORC1 and mTORC2. WYE-354 induces autophagy activation in vitro^[3].

In the DELFIA measuring His6-S6K1 T389 phosphorylation, WYE-354 inhibits recombinant mTOR enzyme with an IC₅₀ of 5 nM^[1]. Cell viability is analyzed by MTS assay. G-415 and TGBC-2TKB cell lines are treated with increasing concentrations of WYE-354 (0.1, 1, 5 and 10 μM) for 24, 48, and 72 hours. WYE-354 significantly reduces cell viability starting at a 1 μM concentration after a 24 hours exposure, in both studied cell lines (P<0.001). A decrease in cell viability is not observed at a dose of 100 nM, except for the TGBC-2TKB cell line after 72 hours of treatment^[2].

The effect of Rapamycin and WYE-354 on tumor growth is evaluated in xenograft GBC tumor models. 2×10⁶ or 5×10⁶ cells of G-415 or TGBC2TKB, respectively, are xenotransplanted into NOD-SCID mice subcutaneously. When tumors reach an average volume of 100 mm³, the mice are treated either with Rapamycin or WYE354. Rapamycin is administered i.p. at a concentration of 10 mg/kg, daily 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. Mice are sacrificed 30 days after the initiation of the treatments and an autopsy is performed that include removal of the entire tumor area. Mice treated with WYE-354 exhibit 68.6% and 52.4% reduction in average tumor size (P<0.01; P<0.01), as well as 82.9% and 45.5% (P<0.01; ns) reduction in tumor weight, respectively^[2].

G-415 and TGBC-2TKB cell lines are plated onto 96 well plates at a density of 2×10³ cells per well. After an overnight attachment period cells are treated with WYE-354. The number of viable cells is determined at certain intervals using CellTiter 96 Aqueous One Solution Cell Proliferation assay. 20 μL CellTiter 96 solution is added to each well and the plates are incubated for 2 hour after which the absorbance of each well is read at a wavelength of 490 nm using a multiwell plate reader. All assays are performed in quintuplicate, and each assay is repeated three times^[2].

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.
