Menabitan

Menabitan (INN; SP-204), or menabitan hydrochloride (USAN), is a synthetic drug which acts as a potent cannabinoid receptor agonist. It is closely related to natural cannabinoids of the tetrahydrocannabinol (THC) group, differing mainly by its longer and branched side chain, and the replacement of the 9-position carbon with a nitrogen. It was studied as an analgesic in the 1970s and was found to possess antinociceptive effects in both humans and animals but was never marketed.
