UR-144

Description

UR-144 is a potent synthetic cannabinoid (CB) which preferentially binds the peripheral CB₂ receptor (K_i = 1.8 nM) over the central CB₁ receptor (K_i = 150 nM).¹ UR-144 N-(5-chloropentyl) analog differs from UR-144 by having a chlorine atom on the terminal carbon of the alkyl group. The biological activities of this compound have not been characterized. ur-144 for sale,ur 144f,xlr-11 for sale,jwh-018,fab-144

UR-144 has high affinity for the CB₂ receptor with a K_i of 1.8 nM but 83x lower affinity for the CB₁ receptor with a K_i of 150 nM.

 UR-144 was found to possess an EC₅₀ of 421 nM for human CB₁ receptors, and 72 nM for human CB₂ receptors.UR-144 produces bradycardia and hypothermia in rats at a dose of 10 mg/kg, suggesting weak cannabinoid-like activity.

Chemically it is closely related to other 2,2,3,3-tetramethylcyclopropyl synthetic cannabinoids like A-796,260 and A-834,735 but with a different substitution on the 1-position of the indole core, in these compounds its 1-pentyl group is replaced with alkylheterocycles like 1-(2-morpholinoethyl) and 1-(tetrahydropyran-4-ylmethyl).

UR-144 is a synthetic cannabinoid that’s been sold as a member of the novel psychoactive substances (NPS) market. It produces some cannabis-like effects, though there’s a lack of information about its activity.

We know the drug works at CB1 and CB2 receptors. ur-144 for sale,fab-144

Those actions seem to result in an effect profile reminiscent of THC and other synthetic cannabinoids. It’s considered more “psychedelic” than some other drugs in the category, but psychedelic-like effects haven’t been reported by all users.ur 144f,xlr-11 for sale,jwh-018

Inhalation (tentative due to a lack of information)

• Range: 2.5 to 20 mg

Most people have been exposed to the drug in the form of “blends” that contain varying levels of UR-144. It’s not wise to use those products.
