Biological Activity
Avobenzone (EC50=14.1 μM) significantly promots adipogenesis in hBM-MSCs as its positive control obesogenic chemicals. Avobenzone (10 μM) significantly up-regulates mRNA levels of PPARγ during adipogenesis in hBM-MSCs[2].
Avobenzone (1-50 μM; 48 hours) inhibits proliferative activities of human trophoblast cells[3].
Avobenzone (1-50 μM; 48 hours) induces apoptosis in HTR8/SVneo cells[3].
Avobenzone only shows weak ERa agonism and weak AR antagonism[4].

* In solvent : -80°C, 6 months; -20°C, 1 month (protect from light, stored under nitrogen)
Solvent & Solubility
DMSO : ≥ 50 mg/mL (161.09 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : < 0.1 mg/mL (insoluble)
* "≥" 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, 6 months; -20°C, 1 month (protect from light, stored under nitrogen). 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: 2.5 mg/mL (8.05 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
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.
