OTS193320
Based on 1 Customer Validation
OTS193320, a imidazo[1,2-a]pyridine compound, is a SUV39H2 methyltransferase activity inhibitor. OTS193320 decreases global histone H3 lysine 9 tri-methylation levels in breast cancer cells and triggers apoptotic cell death. Combination of OTS193320 with Doxorubicin (HY-15142A) results in reduction of γ-H2AX levels as well as cancer cell viability compared to a single agent OTS193320 or DOX.

SUV39H2/KMT1B |
OTS193320 (0.125-0.5 μM; 24 hours) has growth inhibitory effect on breast cancer cell lines. OTS193320 exhibits a high inhibitory effect against SUV39H2 enzymatic activity (IC50=22.2 nM) and a growth suppressive effect of SUV39H2-positive A549 lung cancer cells (IC50=0.38 μM)[1].
OTS193320 (0.5 μM; 48 hours) induces apoptosis in breast cancer cells[1].
OTS193320 (0.125-0.5 μM; 24 hours) causes attenuation of H3K9me3 levels in a dose-dependent manner[1].
OTS193320 sensitizes breast cancer cells to doxorubicin via attenuation of γ-H2AX. Combination of OTS193320 and doxorubicin (DOX) significantly attenuates cancer cell viability in vitro, compared to single agent treatment of either drug[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Solvent & Solubility
DMSO : 62.5 mg/mL (116.60 mM; ultrasonic and warming and heat to 60°C; 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, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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: ≥ 6.25 mg/mL (11.66 mM); Clear solution
This protocol yields a clear solution of ≥ 6.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (62.5 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.
