5F-AB-PINACA is an indazole-based synthetic cannabinoid that is derived from a series of compounds originally developed by Pfizer in 2009 as an analgesic medication, and has been sold online as a designer drug. 5F-AB-PINACA has been reported to be a potent agonist of the CB1 receptor and CB2 receptor with EC50 values of 0.48 nM and 2.6 nM respectively. Its metabolism has been described in literature
5F-AMB is an novelty analogue of AB-PINACA with a systematic name of (R)-methyl 2-(1-(5-fluoropentyl)-1H-indazole-3-carboxamido)-3-methylbutanoate. The chemical formula for 5F-AMB is C19H26FN3O3 with a molecular weight of 363.43 and an exact mass of 363.20.
There have been a number of reported cases of deaths and hospitalizations in relation to this synthetic cannabinoid.It was originally developed by Pfizer in 2009 as an analgesic medication
3,4-Methylenedioxypyrovalerone (also known as MDPV, NRG-1, and imprecisely as Bath Salts, among many others) is a novel, extremely potent synthetic stimulant substance of the cathinone and pyrrolidine chemical classes that produces states of extreme stimulant euphoria, disinhibition, and sexual arousal when administered. MDPV is thought to act primarily as as a norepinephrine-dopamine reuptake inhibitor (NDRI) and possesses powerful euphoric stimulant qualities. It was first developed in the 1960s by a team at Boehringer Ingelheim.
MDPV remained an obscure stimulant until around 2004, when it was reportedly first made available to the public as a designer drug. Products labeled as “bath salts” containing MDPV were previously sold as recreational drugs in gas stations and convenience stores in the United States, similar to the marketing strategy of Spice and K2 as incense.
Historical reports show records of the preparation of MDPV for potential use as a CNS stimulant. It was claimed to have potential to be an alternative for racemic amphetamine and, although showing some desirable qualities such as reduced toxicity as compared to amphetamine, MDPV was chosen to not be developed as a medicinal drug.
