This article is about the recreational drug. For the rocket motor, see Reaction Motors XLR11.

XLR-11 (5"-fluoro-UR-144 or 5F-UR-144) is a drug that acts as a potent agonist for the cannabinoid receptors CB1 and CB2 with EC50 values of 98 nM and 83 nM, respectively.[2] It is a 3-(tetramethylcyclopropylmethanoyl)indole derivative related to compounds such as UR-144, A-796,260 and A-834,735, but it is not specifically listed in the patent or scientific literature alongside these other similar compounds,[3][4] and appears to have not previously been made by Abbott Laboratories, despite falling within the claims of patent WO 2006/069196. XLR-11 was found to produce rapid, short-lived hypothermic effects in rats at doses of 3 mg/kg and 10 mg/kg, suggesting that it is of comparable potency to APICA and STS-135.[2]

Detection

edit

A forensic standard for this compound is available, and a representative mass spectrum has been posted on Forendex.[5]

Recreational use

edit

XLR-11 was instead first identified by laboratories in 2012 as an ingredient in synthetic cannabis smoking blends, and appears to be a novel compound invented specifically for grey-market recreational use.[6]

edit

XLR-11 was banned in New Zealand by being added to the temporary class drug schedule, as of 13 July 2012.[7]

The U.S. Drug Enforcement Administration (DEA) made XLR11 illegal under the Federal Controlled Substances act for the foreseeable future as of January 2024.[8]

It has also been banned in Florida as of 11 December 2012.[9]

Arizona banned XLR-11 on 3 April 2013.[10]

As of October 2015, XLR-11 is a controlled substance in China.[11]

XLR-11 is banned in the Czech Republic.[as of?][12]

Side effects

edit

XLR-11 has been linked to hospitalizations due to its use.[13]

Toxicity

edit

XLR-11 has been linked to acute kidney injury in some users,[14] along with AM-2201.[15][16]
