Discovery of tyrosine-based potent and selective melanocortin-1 receptor small-molecule agonists with anti-inflammatory properties

J Med Chem. 2003 Mar 27;46(7):1123-6. doi: 10.1021/jm025600i.

Abstract

The melanocortin-1 receptor (MC-1R) is a G-protein-coupled receptor involved in inflammation and skin pigmentation. Compound 2 is the first highly potent and selective MC-1R small-molecule agonist reported. Compound 2 showed efficacy in an acute model of inflammation, which has demonstrated the role of MC-1R in modulation of inflammation.
