A series of quinolinyl and isoquinolinyl phenylketones was synthesized and their CB2 receptor-dependent G-protein activities were determined using the [35S]GTPγS binding assay. Both quinoline and isoquinoline derivatives exhibited similar CB2 receptor agonist activity, the most potent ligands being the 2-(Me2N)-phenyl substituted derivatives, which were also full agonists at the CB2-receptor.

A novel, efficient route to biologically and pharmaceutically important o-(dimethylamino)aryl ketones, acridones, acridinium salts, and 1H-indazoles has been developed starting from readily available hydrazones of aldehydes and o-(trimethylsilyl)aryl triflates. The reaction proceeds through arynes under mild conditions, tolerates a wide range of functional groups, and provides the final products in
