CP 47,497 is a cannabinoid receptor agonist drug, developed by Pfizer in the 1980s.[1] It has analgesic effects and is used in scientific research. It is a potent CB1 agonist with a Kd of 2.1nM.[2][3][4]

Homologue

On the 19th of January 2009, the University of Freiburg in Germany announced that an analog of CP 47,497 is the main active ingredient in the herbal "incense" product Spice, specifically the 1,1-dimethyloctyl homologue of CP 47,497. Both the dimethylheptyl and dimethyloctyl homologues were detected in different batches, with considerable variation in the concentration present in different samples that were analysed. The weaker dimethylhexyl and dimethylnonyl homologues were not found in any batches of smoking blends tested, but have been legally scheduled alongside the others in some jurisdictions, to forestall any potential use for this purpose.[5][6][7] The 1,1-dimethyloctyl homologue of CP 47,497 is in fact several times more potent than the parent compound,[8] which is somewhat unexpected as the 1,1-dimethylheptyl is the most potent substituent in classical cannabinoid compounds such as HU-210.[9] The unapproved use of these compounds in herbal smoking blends has led to a resurgence in legitimate scientific research into their use,[10] and consequently the C8 homologue of CP 47,497 has been assigned a proper name, cannabicyclohexanol.[11]


Legal status
