AM-694 AM-694 AM-694 (1-(5-fluoropentyl)-3-(2-iodobenzoyl)indole) is a drug that acts as a potent and selective agonist for the cannabinoid receptor CB. It is used in scientific research for mapping the distribution of CB receptors. No public data about AM-694 metabolism is known. AM-694 has already emerged as a designer drug. AM-694 is an agonist for cannabinoid receptors. Affinities are: with a "K" of 0.08 nM at CB and 18x selectivity over CB with a "K" of 1.44 nM. It is unclear what is responsible for this unusually high CB binding affinity, but it makes the F radiolabelled derivative of AM-694 useful for
