Murine Inducible Nitric Oxide Synthase Oxygenase Domain (Delta 114) 1-Benzo[1,3]dioxol-5-ylmethyl-3S-(4-imidazol-1-yl-phenoxy)-piperidine Complex

Overview

By the screening of a combinatorial library for inhibitors of nitric oxide, (NO) formation by the inducible isoform of nitric oxide synthase (iNOS), using a whole-cell assay, 2-(imidazol-1-yl)pyrimidines were identified., Compounds were found to inhibit the dimerization of iNOS monomers, thus, preventing the formation of the dimeric, active form of the enzyme., Optimization led to the selection of the potent, selective, and orally, available iNOS dimerization inhibitor, 21b, which significantly, ameliorated adjuvant-induced arthritis in a rat model. Analysis of the, crystal structure of the 21b--iNOS monomer complex provided a, rationalization for both the SAR and the mechanism by which 21b blocks the, formation of the protein--protein interaction present in the dimeric form, of iNOS.
