Agonist
An agonist is a chemical that activates a receptor to produce a biological response. Receptors are cellular proteins whose activation causes the cell to modify what it is currently doing. In contrast, an antagonist blocks the action of the agonist, while an inverse agonist causes an action opposite to that of the agonist. Etymology From the Greek αγωνιστής (agōnistēs), contestant; champion; rival < αγων (agōn), contest, combat; exertion, struggle < αγω (agō), I lead, lead towards, conduct; drive Types of agonists can be activated by either endogenous agonists (such as |
ADB-FUBINACA
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. The (''S'')-enantiomer of ADB-FUBINACA is described in a 2009 Pfizer patent and has been reported to be a potent agonist of the CB1 receptor and the CB2 receptor with EC50 values of 1.2 nM and 3.5 nM, respectively. ADB-FUBINACA features a carboxamide group at the 3-indazole position, like SDB-001 and STS-135. ADB-FUBINACA appears to be the product of rational drug design, since it differs from AB-FUBINACA only by the replacement of the isopropyl group with a ''tert''-butyl group. An analogue of ADB-FUBINACA, ADSB-FUB-187, containing a more functionalized carboxamide substituent was recently reported. Side effects One death through coronary arterial thrombosis has been linked to ADB-FUBINACA intoxication. At least an additional 8 deaths in Hungary ...

Cannabinoids
Cannabinoids () are several structural classes of compounds found in the cannabis plant primarily and most animal organisms (although insects lack such receptors) or as synthetic compounds. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary intoxicating compound in cannabis. Cannabidiol (CBD) is a major constituent of temperate Cannabis plants and a minor constituent in tropical varieties. At least 113 distinct phytocannabinoids have been isolated from cannabis, although only four (i.e., THCA, CBDA, CBCA and their common precursor CBGA) have been demonstrated to have a biogenetic origin. It was reported in 2020 that phytocannabinoids can be found in other plants such as rhododendron, licorice and liverwort, and earlier in Echinacea. Phytocannabinoids are multi-ring phenolic compounds structurally related to THC, but endocannabinoids are fatty acid derivatives. Nonclassical synthetic cannabinoids (cannabimimetics) include amin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PX-3
PX-3 (also known as APP-CHMINACA) is an indazole-based synthetic cannabinoid. It is a potent agonist of the CB1 receptor with a binding affinity of ''K''i = 47.6 nM and was originally developed by Pfizer in 2009 as an analgesic medication. The acronym 'APP' signifies the 'amino', 'phenyl' and 'propanone' elements of the structure. Three related compounds, PX-1 (5F-APP-PICA, SRF-30), PX-2 (5F-APP-PINACA, FU-PX) and APP-FUBINACA were reported by the EMCDDA in late 2014. Legality Sweden's public health agency suggested to classify APP-CHMINACA as hazardous substance on June 1, 2015.

MDMB-CHMICA
MDMB-CHMICA is an indole-based synthetic cannabinoid that is a potent agonist of the CB1 receptor and has been sold online as a designer drug. While MDMB-CHMICA was initially sold under the name "MMB-CHMINACA", the compound corresponding to this code name (i.e. the isopropyl instead of t-butyl analogue of MDMB-CHMINACA) has been identified on the designer drug market in 2015 as AMB-CHMINACA. Chemistry Several commercial samples of MDMB-CHMICA were found to exclusively contain the (''S'')-enantiomer based on vibrational and electronic circular dichroism spectroscopy and X-ray crystallography. An (S)-configuration for the ''tert''-leucinate group is unsurprising since MDMB-CHMICA is likely synthesized from the abundant and inexpensive "L" form of the appropriate ''tert''-leucinate reactant. Pharmacology MDMB-CHMICA acts as a highly potent full agonist of the CB1 receptor with an efficacy of 94% and an EC50 value of 0.14 nM, which is approximately 8 times lower than the EC ...

APINACA
APINACA (AKB48, ''N''-(1-adamantyl)-1-pentyl-1''H''-indazole-3-carboxamide) is a drug that acts as a reasonably potent agonist for the cannabinoid receptors, with a Ki of 304.5nM and an EC50 of 585nM at CB1. It had never previously been reported in the scientific or patent literature, and was first identified by laboratories in Japan in March 2012 as an ingredient in synthetic cannabis smoking blends, along with a related compound APICA. Structurally, it closely resembles cannabinoid compounds from a University of Connecticut patent (WO 2003/035005), but with a simple pentyl chain on the indazole 1-position, and APINACA falls within the claims of this patent despite not being disclosed as an example. Legality APINACA was made illegal in Japan in 2012, and was banned as a temporary class drug in New Zealand from 13 July 2012. APINACA has been banned in Latvia since 14 November 2013. Since 2013, APINACA has been a Schedule I controlled substance in the United States. It is al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
APICA (synthetic Cannabinoid Drug)
APICA (2NE1, SDB-001, ''N''-(1-adamantyl)-1-pentyl-1''H''-indole-3-carboxamide) is an indole based drug that acts as a potent agonist for the cannabinoid receptors. It had never previously been reported in the scientific or patent literature, and was first identified by laboratories in Japan in March 2012 as an ingredient in synthetic cannabis smoking blends, along with its indazole derivative APINACA (sold as "AKB48"). Structurally it closely resembles cannabinoid compounds from patenWO 2003/035005but with an indole core instead of indazole, and a simple pentyl chain on the indole 1-position. Given the known metabolic liberation (and presence as an impurity) of amantadine in the related compound APINACA, it is suspected that metabolic hydrolysis of the amide group of APICA may also release amantadine. Pharmacological testing determined APICA to have an IC50 of 175 nM at CB1, only slightly less potent than JWH-018 which had an IC50 of 169 nM, but over four times more ...

ADBICA
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. Legal Status As of October 2015 ADBICA is a controlled substance in China.

CB1 Receptor
Cannabinoid receptor type 1 (CB1), also known as cannabinoid receptor 1, is a G protein-coupled cannabinoid receptor that in humans is encoded by the ''CNR1'' gene. The human CB1 receptor is expressed in the peripheral nervous system and central nervous system. It is activated by: endocannabinoids, a group of retrograde neurotransmitters that include anandamide and 2-arachidonoylglycerol (2-AG); plant phytocannabinoids, such as the compound THC which is an active ingredient of the psychoactive drug cannabis; and, synthetic analogs of THC. CB1 is antagonized by the phytocannabinoid tetrahydrocannabivarin (THCV). The primary endogenous agonist of the human CB1 receptor is anandamide. Structure The CB1 receptor shares the structure characteristic of all G-protein-coupled receptors, possessing seven transmembrane domains connected by three extracellular and three intracellular loops, an extracellular N-terminal tail, and an intracellular C-terminal tail. The receptor may exist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
