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 ...
