PX-3, or APP-CHMINACA, is a synthetic cannabinoid rooted in the indazole structure. Developed by Pfizer in 2009, its original purpose was as an analgesic medication, showcasing potential pharmaceutical utility.
This compound’s acronym, ‘APP,’ signifies its structural elements: ‘amino,’ ‘phenyl,’ and ‘propanone.’ In late 2014, the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) reported three related compounds: PX-1 (5F-APP-PICA, SRF-30), PX-2 (5F-APP-PINACA, FU-PX), and APP-FUBINACA, demonstrating the evolution and diversification of synthetic cannabinoids.
