The effect of SR-3306 or Tat-Sab on cell viability in response to oxidative stress is measured by an MTT assay. H9c2 cells treated with 100 μM H2O2/FeSO4 are ~40% viable, whereas the addition of 500 nM SR-3306 or 500 nM SR3562 to cells treated with 100 μM H2O2/FeSO4 increases viability to ~90%, and the addition of 10 μM Tat-Sab peptide to cells treated with 100 μM H2O2/FeSO4 increases viability to ~70% compared with 98% viability in untreated cells. Similar results are found for primary human cardiomyocytes [2].

Solvent & Solubility
DMSO : 125 mg/mL (254.81 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: ≥ 2.08 mg/mL (4.24 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
H9c2 cells and primary human cardiomyocytes are grown under normal cell culture conditions (37 °C and 5% CO2) in DMEM supplemented with 10% fetal bovine serum and penicillin/streptomycin. To assure that the cells are actively growing, only cells at ~80% confluency and between passages 5 and 15 are used in our experiments. H9c2 cells and primary human cardiomyocytes are exposed to 500 nM SR-3306, 500 nM SR-3562, 0.01% DMSO vehicle control, 10 μM Tat-SabKIM1, and 10 μM Tat-scramble for 30 min prior to the addition of stress. To induce oxidative stress and mitochondrial dysfunction in H9c2 cells and primary human cardiomyocytes, 100 μM hydrogen peroxide (H2O2)/FeSO4 or 100 μM hydrogen peroxide (H2O2)/FeSO4 is added directly to the media of the cells. The cells are exposed to H2O2/FeSO4 for the times indicated in the experiments[2].

Rats[1]
Four Sprague-Dawley rats are used. SR-3306 is dosed at 2.5 or 10 mg/kg in subcutaneous minipumps at a rate of 5 μL/h, and after 24 h on days 1, 2, 3, 4, 6, 7, 8, 9, 10, 13, and 14 blood, and day 14 brain are collected. Plasma is generated, and the samples are frozen at -80 °C. The plasma and brain are mixed with Acetonitrile (1:5 v/v or 1:5 w/v, respectively). The brain sample is sonicated with a probe tip sonicator to break up the tissue, and samples are analyzed for compound levels by LC-MS/MS. Plasma compound levels are determined against standards made in plasma and brain levels against standards made in blank brain matrix[1].
Mice[3]
Male, lean or DIO C57BL/6 mice are used. The mice are trained to scheduled, daily, 2-hour water access during the light for 2 weeks. On the first day of the conditioned taste aversion (CTA) test, the trained mice are given a novel 0.15% saccharin solution to drink for the first 50 minutes, and are then given an i.p. injection of SR-3306 (30 mg/kg or 60 mg/kg) or the vehicle. The injected mice are then provided water for the remaining 70 min. The next day, the mice are allowed to choose between water and 0.15% saccharin for 50 min. Fluid consumption is calculated[3].
