Methanone, [1-(5-fluoropentyl)-2-methyl-1H-indol-3-yl](2,2,3,3-tetramethylcyclopropyl)-

Description

UR-144 is a potent synthetic cannabinoid (CB) which preferentially binds the peripheral cannabinoid (CB₂) receptor (K_i = 1.8 nM) over the central cannabinoid (CB₁) receptor (K_i = 150 nM).¹ M-144 differs from UR-144 by having a fluorine atom on the terminal carbon of the alkyl group as well as a methyl group attached to the C₂ carbon of the indole. The biological activities of this compound have not been characterized. This product is intended for forensic and research applications.
