ADB-P7AICA is a cannabinoid designer drug that has been found as an ingredient in some synthetic cannabis products, first identified by the DEA in early 2021. [1]
ADBICA (also known as ADB-PICA) is a designer drug identified in synthetic cannabis blends in Japan in 2013. ADBICA had not previously been reported in the scientific literature prior to its sale as a component of synthetic cannabis blends. ADBICA features a carboxamide group at the 3-indole position, like SDB-001 and STS-135. The stereochemistry of the tert-butyl side-chain in the product is unresolved, though in a large series of indazole derivatives structurally similar to ADBICA that are disclosed in Pfizer patent WO 2009/106980, activity resides exclusively in the (S) enantiomers. ADBICA is a potent agonist of the CB1 receptor and CB2 receptor with an EC50 value of 0.69 nM and 1.8 nM respectively.
ADB-FUBINACA is a designer drug identified in synthetic cannabis blends in Japan in 2013. In 2018, it was the third-most common synthetic cannabinoid identified in drugs seized by the Drug Enforcement Administration.
AB-CHMINACA is an indazole-based synthetic cannabinoid. It is a potent agonist of the CB1 receptor (Ki = 0.78 nM) and CB2 receptor (Ki = 0.45 nM) and fully substitutes for Δ9-THC in rat discrimination studies, while being 16x more potent. Continuing the trend seen in other cannabinoids of this generation, such as AB-FUBINACA and AB-PINACA, it contains a valine amino acid amide residue as part of its structure, where older cannabinoids contained a naphthyl or adamantane residue.
ADB-PINACA is a cannabinoid designer drug that is an ingredient in some synthetic cannabis products. It is a potent agonist of the CB1 receptor and CB2 receptor with EC50 values of 0.52 nM and 0.88 nM respectively. Like MDMB-FUBINACA, this compound contains an amino acid residue of tert-leucine.
5F-ADB (also known as 5F-MDMB-PINACA) is an indazole-based synthetic cannabinoid from the indazole-3-carboxamide family, which has been used as an active ingredient in synthetic cannabis products and has been sold online as a designer drug. 5F-ADB is a potent agonist of the CB1 receptor, though it is unclear whether it is selective for this target. 5F-ADB was first identified in November 2014 from post-mortem samples taken from an individual who had died after using a product containing this substance. Subsequent testing identified 5F-ADB to have been present in a total of ten people who had died from unexplained drug overdoses in Japan between September 2014 and December 2014. 5F-ADB is believed to be extremely potent based on the very low levels detected in tissue samples, and appears to be significantly more toxic than earlier synthetic cannabinoid drugs that had previously been sold.
ADB-CHMINACA (also known as MAB-CHMINACA) is an indazole-based synthetic cannabinoid. It is a potent agonist of the CB1 receptor with a binding affinity of Ki = 0.289 nM and was originally developed by Pfizer in 2009 as an analgesic medication. It was identified in cannabinoid blends in Japan in early 2015.
5F-APINACA is an indazole-based synthetic cannabinoid that has been sold online as a designer drug. Structurally it closely resembles cannabinoid compounds from patent WO 2003/035005 but with a 5-fluoropentyl chain on the indazole 1-position, and 5F-APINACA falls within the claims of this patent, as despite not being disclosed as an example, it is very similar to the corresponding pentanenitrile and 4-chlorobutyl compounds which are claimed as examples 3 and 4.
APP-FUBINACA is an indazole-based synthetic cannabinoid that has been sold online as a designer drug. Pharmacological testing showed APP-FUBINACA to have only moderate affinity for the CB1 receptor, with a Ki of 708 nM, while its EC50 was not tested. It contains a phenylalanine amino acid residue in its structure.
MMB-2201 is a potent indole-3-carboxamide based synthetic cannabinoid, which has been sold as a designer drug and as an active ingredient in synthetic cannabis blends. It was first reported in Russia and Belarus in January 2014, but has since been sold in a number of other countries. In the United States, MMB-2201 was identified in Drug Enforcement Administration drug seizures for the first time in 2018.
AMB-FUBINACA (also known as FUB-AMB and MMB-FUBINACA) is an indazole-based synthetic cannabinoid that is a potent agonist for the cannabinoid receptors, with Ki values of 10.04 nM at CB1 and 0.786 nM at CB2 and EC50 values of 0.5433 nM at CB1 and 0.1278 nM at CB2, and has been sold online as a designer drug. It was originally developed by Pfizer which described the compound in a patent in 2009, but was later abandoned and never tested on humans. AMB-FUBINACA was the most common synthetic cannabinoid identified in drug seizures by the Drug Enforcement Administration in 2017 and the first half of 2018.
CUMYL-4CN-BINACA (also known as CUMYL-CYBINACA or SGT-78) is an indazole-3-carboxamide based synthetic cannabinoid that has been sold online as a designer drug. It is a potent agonist for cannabinoid receptors CB1 and CB2, with in vitro EC50 values of 0.58 nM and 6.12 nM, respectively. In mice, CUMYL-4CN-BINACA produces hypothermic and pro-convulsant effects via the CB1 receptor, and anecdotal reports suggest it has an active dose of around 0.1 mg in humans.
5F-CUMYL-P7AICA is a pyrrolo[2,3-b]pyridine-3-carboxamide based synthetic cannabinoid that has been sold as a designer drug. It was first identified by the EMCDDA in February 2015.
MDMB-4en-PINACA is an indazole-based synthetic cannabinoid that has been sold online as a designer drug. MDMB-4en-PINACA differs from 5F-MDMB-PINACA due to replacement of 5-fluoropentyl with a pent-4-ene moiety (4-en).
4F-MDMB-BINACA (also known as 4F-MDMB-BUTINACA or 4F-ADB) is an indazole-based synthetic cannabinoid from the indazole-3-carboxamide family. It has been used as an active ingredient in synthetic cannabis products and sold as a designer drug since late 2018. 4F-MDMB-BINACA is an agonist of the CB1 receptor (EC50 = 7.39 nM), though it is unclear whether it is selective for this target. In December 2019, the UNODC announced scheduling recommendations placing 4F-MDMB-BINACA into Schedule II throughout the world.
5F-CUMYL-PEGACLONE (5F-SGT-151, SGT-269) is a gamma-carboline based synthetic cannabinoid that has been sold as a designer drug, first being identified in Germany in 2017. It acts as a potent full agonist of the CB1 receptor. It appears to be more toxic than related compounds such as CUMYL-PEGACLONE, and has been linked to numerous serious adverse reactions, some fatal.
CUMYL-CH-MEGACLONE is a gamma-carboline based synthetic cannabinoid receptor agonist that has been sold as a designer drug, first being identified in Hungary in December 2018.
CUMYL-CBMICA (SGT-280) is an indole-3-carboxamide based synthetic cannabinoid receptor agonist which has been sold as a designer drug, first being identified in Germany in August 2019. Since the structure fell outside the German drug analogue law provisions at the time, an amendment was made to the law to expand the relevant definition, which came into effect in April 2020. It has been shown to act as a CB1 receptor agonist with an EC50 of 62.9nM.
ADB-BINACA is a cannabinoid designer drug that has been found as an ingredient in some synthetic cannabis products. It was originally developed by Pfizer as a potential analgesic, and is a potent agonist of the CB1 receptor with a binding affinity (Ki) of 0.33 nM and an EC50 of 14.7 nM.
ADB-HEXINACA is a cannabinoid designer drug that has been found as an ingredient in some synthetic cannabis products, first appearing in early 2021. It is a longer chain homologue of previously encountered synthetic cannabinoid compounds such as ADB-BUTINACA and ADB-PINACA.
ADB-4en-PINACA is a cannabinoid designer drug that has been found as an ingredient in some synthetic cannabis products, first appearing in early 2021. It is a reasonably potent cannabinoid agonist in vitro but has not been so widely sold as related compounds such as ADB-PINACA and MDMB-4en-PINACA.
