5F-PB-22 (5F-QUPIC or Quinolin-8-yl 1-pentyfluoro-1H-indole-3-8-carboxylate) is a designer drug which acts as a cannabinoid agonist.[1] The structure of 5F-PB-22 appears to have been designed with an understanding of structure-activity relationships within the indole class of cannabinoids.[2]


5F-PB-22 acts as a full agonist with a binding affinity of 0.468nM at CB1 and 0.633nM at CB2 cannabinoid receptors.[3]

Legal Status[edit]

As of October 2015 5F-PB-22 is a controlled substance in China.[4]

In January 2014, 5F-PB-22 was designated as a Schedule I controlled substance in the United States after several deaths were associated with its use.[5][6]
