AM-694

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.^[1]

Pharmacology

AM-694 is an agonist for cannabinoid receptors. It has a K_i of 0.08 nM at CB₁ and 18 times selectivity over CB₂ with a K_i of 1.44 nM.^[2] 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.^[1]

Metabolism

Pathways of metabolism include hydrolytic defluorination, carboxylation, and monohydroxylation of the N-alkyl chain.^[3][4]
