Peptidyl-urea based inhibitors of soluble epoxide hydrolases
摘要:
We prepared a series of amino acid derived cyclohexyl and adamantyl ureas and tested them as inhibitors of the human soluble epoxide hydrolase, and obtained very potent compounds (K-I = 15 nM) that are > 10-fold more soluble than previously described sEH inhibitors. While our lead compound 2 showed low apparent bioavailability in dogs and rats, this series of compounds revealed that sEH inhibitor structures could accept large groups that could lead to better orally available drugs.

Structural refinement of inhibitors of urea-based soluble epoxide hydrolases
摘要:
The soluble epoxide hydrolase (sEH) is involved in the metabolism of arachidonic, linoleic, and other fatty acid epoxides, endogenous chemical mediators that play an important role in blood pressure regulation and inflammation. 1,3-Disubstituted ureas, carbamates, and amides are new potent and stable inhibitors of sEH. However, the poor solubility of the lead compounds limits their use. Inhibitor structure-activity relationships were investigated to better define the structural requirements for inhibition and to identify points in the molecular topography that could accept polar groups without diminishing inhibition potency. Results indicate that lipophilicity is an important factor controlling inhibitor potency. Polar groups could be incorporated into one of the alkyl groups without loss of activity if they were placed at a sufficient distance from the urea function. The resulting compounds had a 2-fold higher water solubility. These findings will facilitate the rational design and optimization of sEH inhibitors with better physical properties.
