PB-22 (QUPIC or 1-pentyl-1H-indole-3-carboxylic acid 8-quinolinyl ester) is a designer drug offered by online vendors as a cannabimimetic agent, and detected being sold in synthetic cannabis products in Japan in 2013.[1] The structure of PB-22 appears to use an understanding of structure-activity relationships within the indole class of cannabimimetics,[original research?] although its design origins are unclear. PB-22 represents a structurally unique synthetic cannabinoid chemotype, since it contains an ester linker at the indole 3-position, rather than the precedented ketone of JWH-018 and its analogs, or the amide of APICA and its analogs.
PB-22 has an EC50 of 5.1 nM for human CB1 receptors, and 37 nM for human CB2 receptors.[2] PB-22 produces bradycardia and hypothermia in rats at doses of 0.3–3 mg/kg, suggesting potent cannabinoid-like activity.[2] The magnitude and duration of hypothermia induced in rats by PB-22 was notably greater than JWH-018, AM-2201, UR-144, XLR-11, APICA, or STS-135, with a reduction of body temperature still observable 6 hours after dosing.[2] One clinical toxicology study found PB-22 to be the cause of seizures in a human and his dog.[3]

Detection
A forensic standard of PB-22 is available, and the compound has been posted on the Forendex website of potential drugs of abuse.[4]
Legal status
As of 9 May 2014, PB-22 is no longer legal in New Zealand.[citation needed]
In January 2014, PB-22 was designated as a Schedule I controlled substance in the United States.[5][6]
Florida also has banned PB-22.[8]
Since 13 December 2014 it is also illegal in Germany because of adding the substance to the BtMG Anlage II.
As of October 2015 PB-22 is a controlled substance in China.[9]
