ADSB-FUB-187 is an indazole-based synthetic cannabinoid. It is a potent agonist of the CB₁ receptor with a binding affinity of K_i = 0.09 nM and an EC₅₀ of 1.09 nM.^[1] It was originally developed by Pfizer in 2009, being example 187 from patent WO 2009/106982. While it is the most tightly binding compound from this patent in terms of K_i, it is not the most potent compound at producing a CB₁ mediated pharmacological effect, with at least 17 other compounds from the patent having lower EC₅₀ values.^[2]

Legality

Sweden's public health agency suggested classifying ADSB-FUB-187 as hazardous substance on November 10, 2014, following its use as an ingredient in grey-market synthetic cannabis products.^[3]
