Pharmacophoric Modeling and Atom-Based 3D-QSAR of Novel 1-Aryl-3-(1-acylpiperidin-4-yl) Urea as Human Soluble Epoxide Hydrolase Inhibitors (sEHIs)

Soluble Epoxide Hydrolase (sEH) is an important and promising new pharmacologic target for the treatment of acute systemic inflammation. Inhibition of sEH by a highly selective and potent sEH inhibitor (sEHI) elevates the epoxyeicosatrienoic acids (EETs) level in vivo leading to decreased inflammation. To explore the necessary structural requirement of 1, 3-disubstituted ureas as sEH inhibitors for anti-inflammatory activity, the molecular modeling studies have been pursued. A ligand-based pharmacophoric model and atom-based 3D-QSAR have been generated by Phase. Binding interaction as determined by the docking study revealed that these inhibitors interact at active site (ASP 335 & TYR 383) of sEH enzyme. The pharmacophore model was further used as a 3D query for virtual screening to retrieve potential inhibitors.
