JWH 073 is a mildly selective agonist of the central cannabinoid (CB1) receptor derived from the aminoalkylindole WIN 55,212-2. The Ki values for binding CB1 and the peripheral CB2 receptor are 8.9 and 38 nM, respectively, for a CB1:CB2 ratio of 0.23. JWH 073 is one of several synthetic CBs which have been included in smoking mixtures. JWH 073 N-(4-hydroxybutyl) β-D-Glucuronide is expected to be a urinary metabolite of JWH 073 based on the metabolism of the closely-related JWH 015 and JWH 018 . The physiological and toxicological properties of this compound have not been tested. This product is intended for forensic and research applications.
