MCHB-1
MCHB-1 is a benzimidazole derived drug which was researched as an analgesic but never developed for medical use. It acts as a potent agonist of the CB2 receptor, with an EC50 of 0.52nM at CB2, and ~30x selectivity over CB1 (Ki of 110nM at CB1 vs 3.7nM at CB2). It has been sold online as a designer drug, first being identified in Germany in December 2013.

Etazen
Etodesnitazene (Desnitroetonitazene, Etazen, Etazene, Etazone) is a benzimidazole derived opioid analgesic drug, which was originally developed in the late 1950s alongside etonitazene and a range of related derivatives. It is many times less potent than etonitazene itself, but still 70x more potent than morphine in animal studies. Corresponding analogues where the N,N-diethyl group is replaced by piperidine or pyrrolidine rings also retain significant activity (10x and 20x morphine respectively). Etodesnitazene has been sold as a designer drug, first being identified in both Poland and Finland in March 2020.

BIM-018
BIM-018 is a synthetic cannabinoid that is the benzimidazole analog of JWH-018. It is presumed to be a potent agonist of the CB2 receptor and has been sold online as a designer drug.

Benzimidazole
Benzimidazole is a heterocyclic aromatic organic compound. This bicyclic compound may be viewed as fused rings of the aromatic compounds benzene and imidazole. It is a colorless solid. Preparation Benzimidazole is produced by condensation of o-phenylenediamine with formic acid,. or the equivalent trimethyl orthoformate: :C6H4(NH2)2 + HC(OCH3)3 → C6H4N(NH)CH + 3 CH3OH 2-substituted derivatives are obtained when the condensation is conducted with aldehydes in place of formic acid, followed by oxidation.Robert A. Smiley "Phenylene- and Toluenediamines" in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH, Weinheim. Reactions Benzimidazole is a base: :C6H4N(NH)CH + H+ → 6H4(NH)2CHsup>+ It can also be deprotonated with stronger bases: :C6H4N(NH)CH + LiH → Li 6H4N2CH + H2 The imine can be alkylated and also serves as a ligand in coordination chemistry.

Analgesic
An analgesic drug, also called simply an analgesic (American English), analgaesic (British English), pain reliever, or painkiller, is any member of the group of drugs used to achieve relief from pain (that is, analgesia or pain management). It is typically used to induce cooperation with a medical procedure. Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and anesthetic effects. Analgesic choice is also determined by the type of pain: For neuropathic pain, traditional analgesics are less effective, and there is often benefit from classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants. Various analgesics, such as many NSAIDs, are available over the counter in most countries, whereas various others are prescription drugs owi ...

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 Receptors can be activated by either agonists (such as[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CB2 Receptor
The cannabinoid receptor type 2, abbreviated as CB2, is a G protein-coupled receptor from the cannabinoid receptor family that in humans is encoded by the ''CNR2'' gene. It is closely related to the cannabinoid receptor type 1 (CB1), which is largely responsible for the efficacy of endocannabinoid-mediated presynaptic-inhibition, the psychoactive properties of tetrahydrocannabinol (THC), the active agent in cannabis, and other phytocannabinoids (plant cannabinoids). The principal endogenous ligand for the CB2 receptor is 2-Arachidonoylglycerol (2-AG). CB2 was cloned in 1993 by a research group from Cambridge looking for a second cannabinoid receptor that could explain the pharmacological properties of tetrahydrocannabinol. The receptor was identified among cDNAs based on its similarity in amino-acid sequence to the cannabinoid receptor type 1 (CB1) receptor, discovered in 1990. The discovery of this receptor helped provide a molecular explanation for the established effects of c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Designer Drug
A designer drug is a structural or functional analog of a controlled substance that has been designed to mimic the pharmacological effects of the original drug, while avoiding classification as illegal and/or detection in standard drug tests. Designer drugs include psychoactive substances that have been designated by the European Union as new psychoactive substances (NPS) as well as analogs of performance-enhancing drugs such as designer steroids. Some of these were originally synthesized by academic or industrial researchers in an effort to discover more potent derivatives with fewer side effects, and shorter duration (and possibly also because it is easier to apply for patents for new molecules) and were later co-opted for recreational use. Other designer drugs were prepared for the first time in clandestine laboratories. Because the efficacy and safety of these substances have not been thoroughly evaluated in animal and human trials, the use of some of these drugs may result i ...

AZD1940
AZD-1940 is a drug developed by AstraZeneca, that is a peripherally selective cannabinoid agonist which binds with high affinity to both the CB1 and CB2 receptors. It was developed for the treatment of neuropathic pain, but while it showed good peripheral selectivity in animal studies, in human clinical trials it failed to show sufficient analgesic efficacy and produced unexpectedly strong side effects associated with central cannabinoid activity, and so was discontinued from further development.

AZ-11713908
AZ-11713908 is a drug developed by AstraZeneca which is a peripherally selective cannabinoid agonist, acting as a potent agonist at the CB1 receptor and a partial agonist at CB2. It has poor blood–brain barrier penetration, and so while it is an effective analgesic in animal tests, it produces only peripheral effects at low doses, with much weaker symptoms of central effects compared to other cannabinoid drugs such as WIN 55,212-2. Many related benzimidazole-derived cannabinoid ligands are known.

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) includ ...
