Endothelial dysfunction is a hallmark of, and plays a pivotal role in the pathogenesis of cardiometabolic diseases, including type II diabetes, obesity, and hypertension. It has been well established that epoxyeicosatrienoic acids (EETs) act as an endothelial derived hyperpolarization factor (EDHF). Soluble epoxide hydrolase (s-EH) rapidly hydrolyses certain epoxylipids (e.

N,N'-Diaryl urea inhibitors of soluble epoxide hydrolase exhibit subtle variations in inhibitory potency depending on the secondary pharmacophore but tolerate considerable structural variation in the second linker/tertiary pharmacophore fragment.

We explored replacement of the adamantyl group in unsymmetrical ureas and amides with substituted aryl rings to identify equipotent and metabolically stable sEH inhibitors. We found that aryl rings, especially those substituted in the para position with a strongly electron withdrawing substituent, afforded enzyme IC(50) values comparable to the adamantyl compounds in an ether substituted, unsymmetrical N,N'-diaryl urea or amide scaffold.

The most potent sEH inhibitors reported to date contain a urea or amide moiety as the central or 'primary' pharmacophore. We evaluated replacing the urea pharmacophore with other functional groups such as thiourea, sulfonamide, sulfonylurea, aminomethylene amide, hydroxyamide, and ketoamide to identify novel and potent inhibitors.
