Abstract

A series of unique indazoles and pyridoindolones have been rationally designed and synthesized as novel classes of cannabinoid ligands based on a proposed bioactive amide conformation. This has led to the discovery of the novel indolopyridone 3a as a conformationally constrained cannabinoid ligand that displays high affinity for the CB2 receptor (K(i)(CB2) = 1.0 nM) and possesses antiinflammatory properties when administered orally in an in vivo murine inflammation model.
