HU-211
Dexanabinol (HU-211 or ETS2101) is a synthetic cannabinoid derivative in development by e-Therapeutics plc. It is the "unnatural" enantiomer of the potent cannabinoid agonist HU-210. Unlike other cannabinoid derivatives, HU-211 does not act as a cannabinoid receptor agonist, but instead as an NMDA antagonist. It therefore does not produce cannabis-like effects, but is anticonvulsant and neuroprotective, and is widely used in scientific research as well as currently being studied for applications such as treating head injury, stroke, or cancer. It was shown to be safe in clinical trials and is currently undergoing Phase I trials for the treatment of brain cancer and advanced solid tumors. Clinical trials Dexanabinol has been studied in IV administration and oral dosing. e-Therapeutics is evaluating the compound in clinical trials for brain and solid cancers. Phase II studies are planned based on the results of the current trials. A phase 1b study for hepatocellular carcinoma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthetic Cannabinoid
Synthetic cannabinoids, or neocannabinoids, are a class of designer drug molecules that Binding affinity, bind to the same receptors to which cannabinoids (Tetrahydrocannabinol, THC, Cannabidiol, CBD and many others) in cannabis plants attach. These novel Psychoactive drug, psychoactive substances should not be confused with synthetic phytocannabinoids (obtained by chemical synthesis) or synthetic Cannabinoid, endocannabinoids from which they are distinct in many aspects. 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 United States and United Kingdom since 2016. They have been marketed as herbal incense, or "herbal smoking blends", and sold under common names such as 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 leg ...

HU-210
HU-210 is a synthetic cannabinoid that was first synthesized in 1988 from (1''R'',5''S'')- myrtenol by a group led by Raphael Mechoulam at the Hebrew University. HU-210 is 100 to 800 times more potent than natural THC from cannabis and has an extended duration of action. HU-210 has a binding affinity of 0.061 nM at CB1 receptors compared to 40.7 nM for Δ9-THC. The binding pose of HU-210 to the CB1 receptor is similar to other synthetic cannabinoids. Effects and research HU-210, the (–) enantiomer, is an ultrapotent cannabinoid, while its (+) enantiomer HU-211 is not a cannabinoid, but an NMDA antagonist with neuroprotective effects. HU-210 has an oral LD50 of 5,000 mg/kg in rats and 14,200 mg/kg in rabbits, and an LDLO (lowest lethal dose) of 143 mg/kg in humans. This is more toxic than Δ8-THC; in monkeys and dogs, 9,000 mg/kg of Δ8-THC was nonlethal. Chemistry HU-210 is the enantiomer of HU-211 ( dexanabinol). The original synthesis ...

NMDA Antagonist
NMDA receptor antagonists are a class of drugs that work to antagonize, or inhibit the action of, the ''N''-Methyl-D-aspartate receptor ( NMDAR). They are commonly used as anesthetics for humans and animals; the state of anesthesia they induce is referred to as dissociative anesthesia. Several synthetic opioids function additionally as NMDAR-antagonists, such as pethidine, levorphanol, methadone, dextropropoxyphene, tramadol, and ketobemidone. Some NMDA receptor antagonists, such as ketamine, dextromethorphan (DXM), phencyclidine (PCP), methoxetamine (MXE), and nitrous oxide (N2O), are sometimes used as recreational drugs, for their dissociative, hallucinogenic, and euphoriant properties. When used recreationally, they are classified as dissociative drugs. Uses and effects NMDA receptor antagonists induce a state called dissociative anesthesia, marked by catalepsy, amnesia, and analgesia. Ketamine is a favored anesthetic for emergency patients with unkno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabinoid
Cannabinoids () are several structural classes of compounds found primarily in the ''Cannabis'' plant or as synthetic compounds. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary psychoactive compound in Cannabis (drug), cannabis. Cannabidiol (CBD) is also a major constituent of temperate cannabis plants and a minor constituent in tropical varieties. At least 100 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 aminoalkylindoles, 1,5-diarylpyrazoles, qu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydroxyarenes
Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile and can catch fire. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. It is acutely toxic and is considered a health hazard. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 million tonnes a year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds, and is a liquid when manufactured. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, explosives such as picric acid, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical dru ...

Etonitazene
Etonitazene, also known as EA-4941 or CS-4640, is a List of benzimidazole opioids, benzimidazole opioid, first reported in 1957, that has been shown to have approximately 1,000 to 1,500 times the potency (pharmacology), potency of morphine in animals. Because it is characterized by a strong drug dependence, dependency potential and a tendency to produce profound respiratory depression, it is not used in humans. It is, however, useful in animal models for addiction studies, particularly those requiring the animals to drink or ingest the agent, because it is not as bitter as opiate salts like morphine sulfate. Synthesis Etonitazene and related nitazenes, nitazene opioids were discovered in the late 1950s, by a team of Swiss researchers working at the pharmaceutical firm CIBA (now Novartis). One of the first compounds investigated by the Swiss team was 1-(β-diethylaminoethyl)-2-benzylbenzimidazole, which was found to possess 10% of the analgesic activity of morphine when tested in ...

Controlled Substance
A controlled substance is generally a drug or chemical whose manufacture, possession and use is regulated by a government, such as illicitly used drugs or prescription medications that are designated by law. Some treaties, notably the Single Convention on Narcotic Drugs, the Convention on Psychotropic Substances, and the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, provide internationally agreed-upon "schedules" of controlled substances, which have been incorporated into national laws; however, national laws usually significantly expand on these international conventions. Some precursor chemicals used for the production of illegal drugs are also controlled substances in many countries, even though they may lack the pharmacological effects of the drugs themselves. Substances are classified according to schedules and consist primarily of potentially psychoactive substances and anabolic steroids. The controlled substanc ...
