UR-144 is a potent synthetic cannabinoid (CB) which preferentially binds the peripheral CB2 receptor (Ki = 1.8 nM) over the central CB1 receptor (Ki = 150 nM). UR-144 N-(5-hydroxypentyl) β-D-glucuronide is an expected major urinary metabolite of UR-144, based on the metabolism of similar cannabimimetics. The physiological and toxicological properties of this compound have not been tested. This product is intended for forensic and research applications.
