AM-1220 is a drug that acts as a potent and moderately selective agonist for the cannabinoid receptor CB1, with around 19x 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 0.27nM at CB1 while the (S) enantiomer has a much weaker Ki of 217nM.[3] 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
As of October 2015 AM-1220 is a controlled substance in China.[8]
