5F-PB22 powder online is a designer drug which acts as a cannabinoid agonist.The structure of 5F-PB-22 appears to have been designed with an understanding of structure–activity relationships within the indole class of cannabinoids
Cannabinoids are commonly smoked or vaporized to achieve a quick onset of effects and rapid offset. 5F-PB-22 is orally active when dissolved in a lipid, which can increase the duration significantly. Like other cannabinoids, it is insoluble in water but dissolves in ethanol and lipids.
5F-PB-22, or quinolin-8-yl 1-pentyfluoro-1H-indole-3-8-carboxylate, is a synthetic indolecarboxylate as it contains a substituted core indole structure. This indole core is shared with other cannabinoid substances including PB-22, JWH-018, and AM2201. 5F-PB-22 is an ether with formula R-O-R’, which can be understood as a substance with two sub-units joined through an oxygen bridge. The indole group of 5F-PB-22 is substituted at R5 with a fluoropentyl chain, a substitution shared with 5F-AKB48. Additionally, the indole core is substituted at R3 with a carboxylic acid group. The terminal oxygen of this carboxylic acid is bonded through an ether bond to a quinoline group at location R8 of the heterocycle.
Although this substance has not been formally studied, from analysis of the structure, it is presumed that 5F-PB-22 has a similar binding profile to that of other cannabinoids and matches many of the in vivo properties of Δ9-THC. However, the role of these interactions and how they result in the cannabinoid high experience continues to remain elusive.
