A new series of CB(1) receptor antagonists incorporating an imidazole-based isosteric replacement for the hydrazide moiety of rimonabant (SR141716) is disclosed. Members of this imidazole series possess potent/selective binding to the rCB(1) receptor and exhibit potent hCB(1) functional activity. Isopropyl analog 9a demonstrated activity in the tetrad assay and was orally-active in a food intake model. (C) 2009 Published by Elsevier Ltd.
