AM-919

AM-919 is an analgesic drug which is a cannabinoid agonist. It is a derivative of HU-210 which has been substituted with a 6β-(3-hydroxypropyl) group. This adds a "southern" aliphatic hydroxyl group to the molecule as seen in the CP- series of nonclassical cannabinoid drugs, and so AM-919 represents a hybrid structure between the classical and nonclassical cannabinoid families.

AM-919 is somewhat less potent than HU-210 itself, but is still a potent agonist at both CB1 and CB2 with moderate selectivity for CB1, with a Ki of 2.2nM at CB1 and 3.4nM at CB2.
