Function

[HYES_HUMAN] Bifunctional enzyme. The C-terminal domain has epoxide hydrolase activity and acts on epoxides (alkene oxides, oxiranes) and arene oxides. Plays a role in xenobiotic metabolism by degrading potentially toxic epoxides. Also determines steady-state levels of physiological mediators. The N-terminal domain has lipid phosphatase activity, with the highest activity towards threo-9,10-phosphonooxy-hydroxy-octadecanoic acid, followed by erythro-9,10-phosphonooxy-hydroxy-octadecanoic acid, 12-phosphonooxy-octadec-9Z-enoic acid, 12-phosphonooxy-octadec-9E-enoic acid, and p-nitrophenyl phospate.^[1] ^[2]

Publication Abstract from PubMed

We have previously reported a series of cyclopropyl urea derivatives as potent orally available soluble epoxide hydrolase (sEH) inhibitors. Here, we designed and synthesized three substituted cyclopropane derivatives that occupy all available pockets of sEH catalytic domain. Compound 14 with a diphenyl substituted cyclopropyl moiety showed good sEH inhibitory activity. Co-crystal structure of this compound and human sEH hydrolase catalytic domain revealed enzyme pockets occupied by the phenoxypiperidine part and the diphenyl cyclopropyl moiety. Furthermore, investigation of the phenoxypiperidine part of compound 14 resulted in the discovery of compound 19, which showed potent sEH inhibitory activity (sub-nM sEH IC50 values).

Three-dimensional rational approach to the discovery of potent substituted cyclopropyl urea soluble epoxide hydrolase inhibitors.,Takai K, Chiyo N, Nakajima T, Nariai T, Ishikawa C, Nakatani S, Ikeno A, Yamamoto S, Sone T Bioorg Med Chem Lett. 2015 Apr 15;25(8):1705-8. doi: 10.1016/j.bmcl.2015.02.076. , Epub 2015 Mar 7.
