AM-694 (1-(5-fluoropentyl)-3-(2-iodobenzoyl)indole) is a designer drug that acts as a potent and selective agonist for the cannabinoid receptor CB1. It is used in scientific research for mapping the distribution of CB1 receptors.

01Pharmacology

AM-694 is an agonist for cannabinoid receptors. It has a Ki of 0.08 nM at CB1 and 18 times selectivity over CB2 with a Ki of 1.44 nM. It is unclear what is responsible for this unusually high CB1 binding affinity, but it makes the 18F radiolabelled derivative of AM-694 useful for mapping the distribution of CB1 receptors in the body.

02Metabolism

Pathways of metabolism include hydrolytic defluorination, carboxylation, and monohydroxylation of the N-alkyl chain.

AM-679 (cannabinoid)

AM-679 is a drug that acts as a moderately potent agonist for the cannabinoid receptors, with a Ki of 13.5 nM at CB1 and 49.5 nM at CB2. AM-679 was one of the first 3-(2-iodobenzoyl)indole derivatives that was found to have significant cannabinoid receptor affinity, and while AM-679 itself has only modest affinity for these receptors, it was subsequently used as a base to develop several more specialised cannabinoid ligands that are now widely used in research, including the potent CB1 agonists AM-694 and AM-2233, and the selective CB2 agonist AM-1241.

AM-1235

AM-1235-3-(naphthalen-1-oyl)-6-nitroindole) is a drug that acts as a potent and reasonably selective agonist for the cannabinoid receptor CB1.

AM-2201

AM-2201-3-(1-naphthoyl)indole) is a recreational designer drug that acts as a potent but nonselective full agonist for the cannabinoid receptor. It is part of the AM series of cannabinoids discovered by Alexandros Makriyannis at Northeastern University.
