Preclinical and human studies have indicated involvement of the ghrelin system in alcohol-related behaviors illuminating the possibility of using ghrelin receptor blockers as a pharmacological intervention for alcohol use disorder (AUD). Preliminary data from a recently conducted phase 1b human study with a ghrelin receptor inverse agonist, PF-5190457 (2-(2-methylimidazo[2,1-b][1,3thiazol-6-yl)-1-{2-(1R)-5-(6-methylpyrimidin-4-yl)-2,3-dihydro-1H-inden-1-yl]-2,7-diazaspiro[3.5]non-7-ylethanone), provided evidence on the safety and tolerability of this compound when co-administered with alcohol. Furthermore, the study revealed important information on the biotransformation pathways for this compound and prompted the discovery and then synthesis of a newly identified major metabolite, PF-6870961 ((R)-1-(2-(5-(2-hydroxy-6-methylpyrimidin-4-yl)-2,3-dihydro-1H-inden-1-yl)-2,7-diazaspiro[3.5]nonan-7-yl)-2-(2-methylimidazo[2,1-b]thiazol-6-yl)ethan-1-one). The metabolite was synthesized and fully characterized through a design that enabled it to be prepared in useful quantities. The synthesis provided direct access to the recently discovered PF-6870961 and is allowing researchers to conduct additional and deeper evaluation of its in vitro and in vivo properties.

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.
