FUB-PB22 with the formal name of quinolin-8-yl 1-(4-fluorobenzyl)-1H-indole-3-carboxylate and is a substitute of 5F-PB22 and PB22. The molecular formula is C25H17FN2O2 with a molecular weight of 396.41 and an exact mass of 396.13. FUB-PB22 is a white powder, developed on an indazole base, which sets it apart from several other JWH compounds having an indolyl base. At this time, research on FUB-PB22 has not determined the biochemical, physiological, and toxicological properties, thus more research is needed.
FUB-PB-22 acts as a full agonist with a binding affinity of 0.386nM at CB1 and 0.478nM at CB2cannabinoid receptors.
As of October 2015 FUB-PB-22 is a controlled substance in China.
It is also banned in Sweden.
