JWH-133
JWH-133 (Dimethylbutyl-deoxy-Delta-8-THC) is a potent selective CB2 receptor agonist with a Ki of 3.4nM and selectivity of around 200x for CB2 over CB1 receptors. It was discovered by and named after John W. Huffman. JWH-133 has been confused with other analogs of Delta-8-THC in peer-reviewed literature. It has been confused with Dimethylpentyl-Delta-8-THC as well as Dimethylbutyl-Delta-8-THC, including confusing the chemical name with Dimethylbutyl-Delta-8-THC itself. It has been confused with the Delta-9 isomer The 3-(1',1'-Dimethylbutyl)-1-deoxy-delta-8-THC is a selective CB2 agonist, binding 677nM at Cb1 and 3.4nM at CB2 while 3-(1',1'-Dimethylbutyl)-delta-8-THC itself binds 65nM at CB1. Structurally the only difference between JWH-133 and dimethylbutyl-D8-THC is that JWH-133 lacks the hydroxy group seen on dimethylbutyl-D8-THCs phenol structure (the C1 position of the A ring), turning this group into a phenyl (JWH-133) instead of phenol. It is generally accepted that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabinoid Receptor Type 2
The cannabinoid receptor 2 (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 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 1 (CB1) receptor, discovered in 1990. The discovery of this receptor helped provide a molecular explanation for the established effects of cannabinoids on the immu ...

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] |
WIN 55,212-2
WIN 55,212-2 is a chemical described as an aminoalkylindole derivative, which produces effects similar to those of cannabinoids such as tetrahydrocannabinol (THC) but has an entirely different chemical structure. WIN 55,212-2 is a potent cannabinoid receptor agonist that has been found to be a potent analgesic in a rat model of neuropathic pain. It activates p42 MAP kinase, p42 and p44 MAP kinase, p44 MAP kinase via receptor-mediated signaling. At 5 μM WIN 55,212-2 inhibits Adenosine Triphosphate, ATP production in sperm in a CB1 receptor, CB1 receptor-dependent fashion. WIN 55,212-2, along with HU-210 and JWH-133, may prevent the inflammation caused by amyloid beta proteins involved in Alzheimer's disease, in addition to preventing cognitive impairment and loss of neuronal genetic markers, markers. This anti-inflammatory action is induced through agonist action at cannabinoid receptors, which prevents microglial activation that elicits the inflammation. WIN 55,212-2 is a ful ...

Microglia
Microglia are a type of glia, glial cell located throughout the brain and spinal cord of the central nervous system (CNS). Microglia account for about around 5–10% of cells found within the brain. As the resident macrophage cells, they act as the first and main form of active immune defense in the CNS. Microglia originate in the yolk sac under tightly regulated molecular conditions. These cells (and other neuroglia including astrocytes) are distributed in large non-overlapping regions throughout the CNS. Microglia are key cells in overall brain maintenancethey are constantly scavenging the CNS for senile plaques, plaques, damaged or unnecessary neurons and synapses, and infectious agents. Since these processes must be efficient to prevent potentially fatal damage, microglia are extremely sensitive to even small pathological changes in the CNS. This sensitivity is achieved in part by the presence of unique potassium channels that respond to even small changes in extracellular pota ...

BtMG
The Narcotic Drugs Act (, or BtMG) is the controlled substances law of Germany. In common with the Misuse of Drugs Act of 1971 of the United Kingdom and Controlled Substances Acts of the US and Canada, it is a consolidation of prior regulation and an implementation of treaty obligations under the Single Convention on Narcotic Drugs, Convention on Psychotropic Substances and other treaties. The BtMG updated the German Opium Law 1929 and mirrors the Swiss BtMG and Austrian Suchtmittelgesetz. The German Narcotics Act was re-announced on 1 March 1994. The last change to the law was the legalization of Cannabis in Germany on 1 April 2024. Since then, the handling of this drug has been subject to the German cannabis control bill.

Federal Analogue Act
The Federal Analogue Act, , is a section of the United States Controlled Substances Act passed in 1986 which allows any chemical "substantially similar" to a controlled substance listed in Schedule I or II to be treated as if it were listed in Schedule I, but only if intended for human consumption. These similar substances are often called designer drugs. The law's broad reach has been used to successfully prosecute possession of chemicals openly sold as dietary supplements and naturally contained in foods (e.g., the possession of phenethylamine, a compound found in chocolate, has been successfully prosecuted based on its "substantial similarity" to the controlled substance methamphetamine). The law's constitutionality has been questioned by now Supreme Court Justice Neil Gorsuch on the basis of Vagueness doctrine. Definition (32) *(A) Except as provided in subparagraph (C), the term ''controlled substance analogue'' means a substance - **(i) the chemical structure of which ...

Controlled Substances Act
The Controlled Substances Act (CSA) is the statute establishing federal government of the United States, federal drug policy of the United States, U.S. drug policy under which the manufacture, importation, possession, use, and distribution of certain substances is regulated. It was passed by the 91st United States Congress as Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970 and signed into law by President Richard Nixon. The Act also served as the national implementing legislation for the Single Convention on Narcotic Drugs. The legislation created five schedules (classifications), with varying qualifications for a substance to be included in each. Two federal agencies, the Drug Enforcement Administration (DEA) and the Food and Drug Administration (FDA), determine which substances are added to or removed from the various schedules, although the statute passed by Congress created the initial listing. Congress has sometimes scheduled other substances t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neurotoxicity
Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant– alters the normal activity of the nervous system in such a way as to cause permanent or reversible damage to nervous tissue. This can eventually disrupt or even kill neurons, which are cells that transmit and process signals in the brain and other parts of the nervous system. Neurotoxicity can result from organ transplants, radiation treatment, certain drug therapies, recreational drug use, exposure to heavy metals, bites from certain species of venomous snakes, pesticides, certain industrial cleaning solvents, fuels and certain naturally occurring substances. Symptoms may appear immediately after exposure or be delayed. They may include limb weakness or numbness, loss of memory, vision, and/or inte ...

Amyloid Beta
Amyloid beta (Aβ, Abeta or beta-amyloid) denotes peptides of 36–43 amino acids that are the main component of the amyloid plaques found in the brains of people with Alzheimer's disease. The peptides derive from the amyloid-beta precursor protein (APP), which is cleaved by Beta-secretase 1, beta secretase and gamma secretase to yield Aβ in a cholesterol-dependent process and substrate presentation. Both neurons and oligodendrocytes produce and release Aβ in the brain, contributing to formation of amyloid plaques. Aβ molecules can aggregate to form flexible soluble oligomers which may exist in several forms. It is now believed that certain misfolded oligomers (known as "seeds") can induce other Aβ molecules to also take the misfolded oligomeric form, leading to a chain reaction akin to a prion infection. The oligomers are toxic to nerve cells. The other protein implicated in Alzheimer's disease, tau protein, also forms such prion-like misfolded oligomers, and there is some ev ...

Alzheimer's Disease
Alzheimer's disease (AD) is a neurodegenerative disease and the cause of 60–70% of cases of dementia. The most common early symptom is difficulty in remembering recent events. As the disease advances, symptoms can include problems with language, disorientation (including easily getting lost), mood swings, loss of motivation, self-neglect, and behavioral issues. As a person's condition declines, they often withdraw from family and society. Gradually, bodily functions are lost, ultimately leading to death. Although the speed of progression can vary, the average life expectancy following diagnosis is three to twelve years. The causes of Alzheimer's disease remain poorly understood. There are many environmental and genetic risk factors associated with its development. The strongest genetic risk factor is from an allele of apolipoprotein E. Other risk factors include a history of head injury, clinical depression, and high blood pressure. The progression of the di ...
