Virtual screening of novel CB2 ligands using a comparative model of the human cannabinoid CB2 receptor

J Med Chem. 2005 Nov 17;48(23):7166-71. doi: 10.1021/jm050565b.

Abstract

To identify novel selective CB2 lead compounds, a comparative model of the CB2 receptor was constructed using the high-resolution bovine rhodopsin X-ray structure as a template. The CB2 model was utilized both in building the database queries and in filtering the hit compounds by a docking and scoring method. In G-protein activation assays, 1-isoquinolyl[3-(trifluoromethyl)phenyl]methanone (40, NRB 04079) was found to act as a selective agonist at the human CB2 receptor.
