GSTO1-IN-1 (C1-27) potently inhibits GSTO1 enzyme activity with an IC50 value of 31 nM. GSTO1-IN-1 also potently competes with 5-chloromethylfluorescein diacetate (CMFDA) for binding to recombinant protein, as well as endogenous GSTO1 in the milieu of a soluble proteome. HCT116 cells treated with GSTO1-IN-1 also show a decrease in cell viability in a dose-dependent manner. GSTO1-IN-1 inhibits the clonogenic survival of HCT116 cells at sub-micromolar concentrations[1].

Solvent & Solubility
DMSO : ≥ 300 mg/mL (964.07 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
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 (8.03 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 (8.03 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
Cell proliferation is assessed by a MTT assay. Cancer cells H630, HT29 and HCT116 are seeded in 96-well microtitre plates and, after overnight attachment, treated with GSTO1 inhibitors (e.g., GSTO1-IN-1; 0.1, 1, 10 and 100 μM). After 72 h, MTT solution (3 mg/mL; 20mL) is added to each well and cells are incubated for 3 h at 37°C. After incubation, media from each well is removed and the dark blue formazan crystals formed by live cells are dissolved in DMSO (150 mL per well). The absorbance intensity is measured at 570 nm on a microplate reader. Cell viability after 24 h treatment is assessed using ApoTox-Glo triplex assay. At least three independent dose-response experiments with each concentration tested in triplicate are performed for each cell line[1].

Mice[1]
In the pilot study, HCT116 cells (1×106) in exponential phase are injected subcutaneously into the left flank of 8- to 10-week-old female nude mice (25-30 g) . The perpendicular diameters of the tumors are measured three times weekly using standard calipers and tumour volumes are calculated. Tumors are allowed to grow to a volume of 50 mm3 and mice are randomized into control (n=5) and GSTO1-IN-1 (n=3) treatment groups. GSTO1-IN-1 is administered intraperitoneally (20 mg/kg per day) for the first 2 weeks on a 5 days on/2 days off schedule. The dose is then increased to 25 mg/kg per day for the next 23 days and further escalated by 5 mg/kg per day to a final dose of 45 mg/kg for the remaining duration of treatment. Tumor volumes and body weights are measured three times weekly to monitor tumor burden and weight loss during treatment. At the end of the experiment, animals are killed and tumor, kidney and liver are collected, fixed and paraffin embedded for histology[1].
