Treatment of HL-60 cells with Tosedostat (CHR-2797) leads to an increase in the secretion of Stanniocalcin 2 (STC2) protein into the growth medium. Increases in SLC7A11 expression are detectable at 60 nM Tosedostat and as early as 2 h posttreatment. The IC50s for inhibition of proliferation by Tosedostat in U-937 and HuT 78 cell lines are 10 nM and >10 μM, respectively. Tosedostat treatment increases expression of amino acid deprivation response (AADR) genes in U-937 cells but not in HuT 78 cells[1]. By 24 h with 0.01 μM Tosedostat the mean MCA production is reduced to 77.8% of the untreated control cells; similarly the MCA production is reduced to 51.3% with 1 μM, 38.5% with 5 μM, and 35.3% with 10 μM Tosedostat[2].

Solvent & Solubility
DMSO : 100 mg/mL (246.02 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.15 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.15 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Protocol
Cells are seeded at a density of 4×104/mL, cultured for 24 h, then treated with 0.06 to 6 μM Tosedostat (CHR-2797) for 24 h. After treatment, 5×104 cells are washed with PBS and seeded in 100 μL Cys/Met-free RPMI 1640 containing Tosedostat, supplemented with 10% dialyzed FBS. 1.5 μCi [35S]Cys/Met (>1,000 Ci/mmol) is added, and incubation continued for 1 h at 37°C. Cells are captured onto 96-well GF/B filter plates and washed twice with PBS before precipitation with 10% ice-cold trichloroacetic acid (TCA) for 1 h at 4°C. Precipitated proteins are washed four times with ice-cold 10% TCA and air-dried for 1 h. UltimaGold scintillation cocktail is added and allowed to mix for 1 h before scintillation counting using a scintillation counter[1].

Leukemic cells are washed and suspended in phosphate buffered saline (PBS). 100 μL of cell suspension (1×105 cells/mL) is mixed with 100 μL of Tosedostat (CHR-2797) (0.01 to 10 μM) and 200 μM L-alanine 4-methyl-coumaryl-7-amide (ala-MCA) in a 96 well plate in duplicate. The aminopeptidase activity is measured by detecting the fluorescent 7-amino-4-methylcoumarin (MCA) liberated from the cleavage of ala-MCA by cellular aminopeptidases (excitation 355 nm, emission 460 nm)[2].

A breeding colony of NOD/SCID IL2R gammanull mice are used in this study. The mice are inoculated subcutaneously in the right flank with 2×106 H929 myeloma cells in 50 μL RPMI-1640 and 50 μL MatrigelTM Basement Membrane Matrix Growth Factor Reduced. The mice are assigned into the following four treatment groups (10 animals per group): no treatment, Tosedostat 75 mg/kg, CHR-3996 30 mg/kg, and Tosedostat 75 mg/kg with concomitant CHR-3996 30 mg/kg. Tosedostat is administered daily by intra-peritoneal injection beginning four days after the tumour cells are inoculated. Caliper measurements of the longest perpendicular tumour diameters (length) and width are performed every other day to estimate the tumour volume[3].
