Adapalene
Based on 5 publication(s) in Google Scholar
Adapalene (CD271), a third-generation synthetic retinoid, is widely used for the research of acne. Adapalene is a potent RAR agonist, with AC50s of 2.3 nM, 9.3 nM, and 22 nM for RARβ, RARγ, RARα, respectively. Adapalene also inhibits the enzymatic activity of GOT1 in a non-competitive manner. Adapalene exhibits anti-tumor activity.

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: 1 mg/mL (2.42 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 1 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
