5F-APINACA, also recognized as 5F-AKB-48 or 5F-AKB48, is a synthetic cannabinoid based on the indazole structure and has been available for purchase as a designer drug online. In terms of its chemical structure, it closely resembles cannabinoid compounds outlined in patent WO 2003/035005, differing by the presence of a 5-fluorophenyl chain on the indazole 1-position. Interestingly, 5F-APINACA falls under the claims of this patent despite not being explicitly disclosed as an example. This is due to its striking similarity to the pentane nitrile and 4-chlorobutyl compounds described in examples 3 and 4 in the patent.
5F-APINACA was initially identified in South Korea. It is anticipated to exhibit strong agonistic activity towards both the CB1 and CB2 receptors, as suggested by available research. Furthermore, the metabolism of 5F-APINACA has been documented in scientific literature.
