Ombuoside (0-100 μM, 24-26 h) inhibits HEI-OC1 cells growth only treatment with 80 or 100 μM, increases the survival of Cisplatin (HY-17394)-treated HEI-OC1 cells, with the 30 μM dose demonstrating the most protective effect[1].
Ombuoside (30 μM, 24 h) reduces Cisplatin-induced apoptosis, oxidative stress via the mitochondria-related apoptotic pathway in HEI-OC1 cells[1].
Ombuoside (30 μM, 24 h) protects cochlear explants from Cisplatin-induced hair cell damage by inhibiting apoptosis[1].
Ombuoside (1-100 μM, 1-72 h) reduces PC12 cells viability to 80.4% of the control level at 100 µM, increases the cell viability in L-DOPA (HY-N0304)- induced PC12 cells[2].
Ombuoside (1-10 μM, 0-6 h) decreases phosphorylation of ERK1/2 and JNK1/2, the expression of cleaved-caspase-3, increases SOD activity in L-DOPA- induced PC12 cells[2].
Ombuoside (1-10 μM, 0-24 h) increases Dopamine (HY-B0451) levels in a time- and dose-dependent manner, increases the phosphorylation of TH (Ser40) and CREB (Ser133) level in PC12 cells[3].

Solvent & Solubility
DMSO : 50 mg/mL (78.30 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, 6 months; -20°C, 1 month (protect from light). 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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1.25 mg/mL (1.96 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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.
