MDMB-4en-PINACA
MDMB-4en-PINACA (also incorrectly known as 5-CL-ADB-A) is an indazole-based synthetic cannabinoid that has been sold online as a designer drug. In 2021, MDMB-4en-PINACA was the most common synthetic cannabinoid identified by the Drug Enforcement Administration in the United States. MDMB-4en-PINACA differs from 5F-MDMB-PINACA due to replacement of 5-fluoropentyl with a pent-4-ene moiety (4-en). It acts as a potent agonist of the CB1 receptor with an EC50 value of 2.47 nM. Legal status Sweden's public health agency suggested classifying MDMB-4en-PINACA as a hazardous substance, on December 18, 2019.

Indazole
Indazole, also called isoindazole, is a heterocyclic aromatic organic compound. This bicyclic compound consists of the fusion of benzene and pyrazole. Indazole is an amphoteric molecule which can be protonated to an indazolium cation or deprotonated to an indazolate anion. The corresponding ''pKa'' values are 1.04 for the equilibrium between indazolium cation and indazole and 13.86 for the equilibrium between indazole and indazolate anion. Indazole derivatives display a broad variety of biological activities. Indazoles are rare in nature. The alkaloids nigellicine, nigeglanine, and nigellidine are indazoles. Nigellicine was isolated from the widely distributed plant ''Nigella sativa'' L. (black cumin). Nigeglanine was isolated from extracts of ''Nigella glandulifera''. The Davis–Beirut reaction can generate 2''H''-indazoles. Indazole, C7H6N2, was obtained by E. Fischer (''Ann.'' 1883, 221, p. 280) by heating ortho-hydrazine cinnamic acid, : Some derivatives ; indazole-3- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthetic Cannabinoid
Synthetic cannabinoids are a class of designer drug molecules that bind to the same receptors to which cannabinoids (THC, CBD and many others) in cannabis plants attach. These novel psychoactive substances should not be confused with synthetic phytocannabinoids (THC or CBD obtained by chemical synthesis) or synthetic endocannabinoids from which they are in many aspects distinct. Typically, synthetic cannabinoids are sprayed onto plant matter and are usually smoked, although they have also been ingested as a concentrated liquid form in the US and UK since 2016. They have been marketed as herbal incense, or "herbal smoking blends", and sold under common names like K2, spice, and synthetic marijuana. They are often labeled "not for human consumption" for liability defense. A large and complex variety of synthetic cannabinoids are designed in an attempt to avoid legal restrictions on cannabis, making synthetic cannabinoids designer drugs. Most synthetic cannabinoids are agonists o ... [...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 ...

5F-ADB
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. In 2018, 5F-ADB was the most common synthetic cannabinoid to be identified in Drug Enforceme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 |
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] |
EC50
] Half maximal effective concentration (EC50) is a measure of the concentration of a drug, antibody or toxicant which induces a Stimulus%E2%80%93response_model, response halfway between the baseline and maximum after a specified exposure time. More simply, EC50 can be defined as the ''concentration required to obtain a 50% ..effect'' and may be also written as sub>50. It is commonly used as a measure of a drug's potency, although the use of EC50 is preferred over that of 'potency', which has been criticised for its vagueness. EC50 is a measure of concentration, expressed in molar units (M), where 1 M is equivalent to 1 mol/ L. The EC50 of a ''graded'' dose response curve therefore represents the concentration of a compound where 50% of its maximal effect is observed. The EC50 of a ''quantal'' dose response curve represents the concentration of a compound where 50% of the population exhibit a response, after a specified exposure duration. For clarification, a grade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ADB-PINACA
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. Side effects ADB-PINACA has been linked to multiple hospitalizations and deaths due to its use. Metabolism Nineteen ADB-PINACA major metabolites were identified in several incubations with cryopreserved human hepatocytes. Major metabolic reactions included pentyl hydroxylation, hydroxylation followed by oxidation (ketone formation), and glucuronidation. Legality ADB-PINACA is listed in the Fifth Schedule of the Misuse of Drugs Act (MDA) and therefore illegal in Singapore as of May 2015. In the United States, it is a Schedule I controlled substance. As of October 2015 ADB-PINACA is a controlled substance in China. See also * 5F-AB-PINACA * 5F-ADB * 5F-ADB-PINACA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
