MR-L2
Based on 2 publication(s) in Google Scholar
MR-L2 is a reversible and noncompetitive allosteric activator of long-isoform phosphodiesterase-4 (PDE4), activates representative PDE4 long-isoform variants (PDE4A4, PDE4B1, PDE4C3, PDE4D5). MR-L2 suppresses PGE2-induced MDCK cell cyst formation with an EC50 of 1.2 μM.

Cell Line:Madin-Darby Canine Kidney (MDCK) cell line
-
Concentration:0.3, 1, 3 and 10 μM

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.
