AB-FUBINACA Chemical compound

AB-FUBINACA is a drug that acts as a potent agonist for the cannabinoid receptors, with Ki values of 0.9 nM at CB1 and 23.2 nM at CB2 and EC50 values of 1.8 nM at CB1 and 3.2 nM at CB2. It was originally developed by Pfizer in 2009 as an analgesic medication but was never pursued for human use. In 2012, it was discovered as an ingredient in synthetic cannabinoid blends in Japan, along with a related compound AB-PINACA, which had not previously been reported.

ADBICA Group of stereoisomers

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 Chemical compound

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 Chemical compound

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 Chemical compound

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 Chemical compound

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 Chemical compound

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-AMB Chemical compound

5F-AMB (also known as 5F-MMB-PINACA and 5F-AMB-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. It was first identified in Japan in early 2014. Although only very little pharmacological information about 5F-AMB itself exists, its 4-cyanobutyl analogue (instead of 5-fluoropentyl) has been reported to be a potent agonist for the CB1 receptor (KI = 0.7 nM).

5F-APINACA Chemical compound

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.

MDMB-FUBINACA Chemical compound

MDMB-FUBINACA (also known as MDMB(N)-Bz-F and FUB-MDMB) is an indazole-based synthetic cannabinoid that is a potent agonist for the cannabinoid receptors, with Ki values of 1.14 nM at CB1 and 0.1228 nM at CB2 and EC50 values of 0.2668 nM at CB1 and 0.1411 nM at CB2, and has been sold online as a designer drug. Its benzyl analogue (instead of 4-fluorobenzyl) has been reported to be a potent agonist for the CB1 receptor (Ki = 0.14 nM, EC50 = 2.42 nM). The structure of MDMB-FUBINACA contains the amino acid 3-methylvaline or tert-leucine methyl ester.

PX-1 Chemical compound

PX-1 is an indole-based synthetic cannabinoid that has been sold online as a designer drug.

PX-2 Chemical compound

APP-FUBINACA Chemical compound

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.

5F-ADB-PINACA Chemical compound

5F-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 0.24 nM and 2.1 nM respectively.

AB-PICA Chemical compound

AB-PICA is a potent agonist for the CB1 receptor (EC50 = 12 nM) and CB2 receptor (EC50 = 12 nM).

AMB-FUBINACA Chemical compound

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.

AMB-CHMINACA Chemical compound

AMB-CHMINACA or MMB-CHMINACA (also known as MA-CHMINACA) is an indazole-based synthetic cannabinoid that is a potent agonist of the CB1 receptor and has been sold online as a designer drug.

FUB-APINACA Chemical compound

FUB-APINACA (also known as AFUBINACA and FUB-AKB48) is an indazole-based synthetic cannabinoid that is presumed to be a potent agonist of the CB1 receptor and has been sold online as a designer drug. It is an analog of APINACA and 5F-APINACA where the pentyl chain has been replaced with fluorobenzyl.

Adamantyl-THPINACA Chemical compound

Adamantyl-THPINACA is an indazole-based synthetic cannabinoid, which was first reported to Europol in Slovenia in January 2015. It is known as both the 1-adamantyl and 2-adamantyl isomers, which can be distinguished by GC-EI-MS. It is banned in Sweden and Russia. Both the 1-adamantyl and 2-adamantyl isomers are specifically listed as illegal drugs in Japan. Given the known metabolic liberation of amantadine in the related compound APINACA, it is suspected that metabolic hydrolysis of the amide group of Adamantyl-THPINACA may also release amantadine.

5F-EMB-PINACA Chemical compound

5F-EMB-PINACA is an indazole-based synthetic cannabinoid from the indazole-3-carboxamide family that has been sold online as a designer drug.
