R59949
Based on 2 publication(s) in Google Scholar
R59949 is a pan diacylglycerol kinase (DGK) inhibitor with an IC50 of 300 nM. R59949 strongly inhibits the activity of type I DGK α and γ and moderately attenuates the activity of type II DGK θ and κ. R59949 activates protein kinase C (PKC) by enhancing the levels of the endogenous ligand diacyl glycerol.

In the presence of R59949, vasopressin- as well as collagen-induced release reaction and aggregation was strongly increased, independently of the formation of arachidonate metabolites[1].
In THP‐1 monocytes, R59949 attenuates CCL2‐evoked Ca2+ signalling with a half‐maximal concentration of 8.6 μM[2].
R59949 inhibits inducible nitric oxide production through decreasing transplasmalemmal L-arginine uptake in vascular smooth muscle cells[4].

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.
