AM-1220 is a drug that acts as a potent and moderately selective agonist for the cannabinoid receptor CB1, with around 19 times selectivity for CB1 over the related CB2 receptor.[1] It was originally invented in the early 1990s by a team led by Thomas D'Ambra at Sterling Winthrop,[2] but has subsequently been researched by many others, most notably the team led by Alexandros Makriyannis at the University of Connecticut. The (piperidin-2-yl)methyl side chain of AM-1220 contains a stereocenter, so there are two enantiomers with quite different potency, the (R)-enantiomer having a Ki of 0.27 nM at CB1 while the (S)-enantiomer has a much weaker Ki of 217 nM.[3]

Related compounds[edit]

A number of related compounds are known with similar potent cannabinoid activity, with modifications such as substitution of the indole ring at the 2- or 6-positions, the naphthoyl ring substituted at the 4-position or replaced by substituted benzoyl rings or other groups, or the 1-(N-methylpiperidin-2-ylmethyl) group replaced by similar heterocyclic groups such as N-methylpyrrolidin-2-ylmethyl or N-methylmorpholin-3-ylmethyl.[4][5][6] AM-1220 was first detected as an ingredient of synthetic cannabis smoking blends in 2010.[7]

Legal status[edit]

==United States== in the United States of America all CB1 receptor agonists of the 3-(1-naphthoyl)indole class such as AM-1220 are Schedule I Controlled Substances under the Controlled Substances Act s.[8] ==United Kingdom== it's illegal to supply, smuggle, distribute, transport, sell or trade the pharmaceutical drug under the Psychoactive Substances Act 2016 which was enforced on May26th 2016.

As of October 2015, AM-1220 is a controlled substance in China.[9]
