Nabidrox
Canbisol (Nabidrox), is a synthetic cannabinoid derivative that is the dimethylheptyl homologue of 9-''nor''-9β-hydroxyhexahydrocannabinol ( HHC). It is a potent agonist at both the CB1 and CB2 receptors, with a binding affinity of 0.1nM at CB1 and 0.2nM at CB2. It is mainly used in scientific research, in receptor binding studies to determine the structure and function of the cannabinoid receptors, but has been made illegal in some countries due to its possible abuse potential as a cannabinomimetic drug. See also * HU-210 * HU-243 * Nabilone Nabilone, sold under the brand name Cesamet among others, is a synthetic cannabinoid with therapeutic use as an antiemetic and as an adjunct analgesic for neuropathic pain.

HU-243
HU-243 (AM-4056) is a synthetic cannabinoid drug that is a single enantiomer of the hydrogenated derivative of the commonly used reference agonist HU-210. It is a methylene homologue of canbisol. It is a potent agonist at both the CB1 and CB2 receptors, with a binding affinity of 0.041 nM at the CB1 receptor, making it marginally more potent than HU-210, which had an affinity of 0.061 nM in the same assay. Legal status HU-243 is not listed in the schedules set out by the United Nations' Single Convention on Narcotic Drugs from 1961 nor their Convention on Psychotropic Substances from 1971, so the signatory countries to these international drug control treaties are not required by said treaties to control HU-243. United States HU-243 is not listed in the list of scheduled controlled substances in the USA. It is therefore not scheduled at the federal level in the United States, but it is possible that HU-243 could legally be considered an analog of THC (which i ...

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] |
Homology (chemistry)
In chemistry, homology is the appearance of homologues. A homologue (also spelled as homolog) is a compound belonging to a series of compounds differing from each other by a repeating unit, such as a methylene bridge −−, a peptide residue, etc. A homolog is a special case of an analog. Examples are alkanes and compounds with alkyl side chains of different length (the repeating unit being a methylene group -CH2-). Periodic table On the periodic table, homologous elements share many electrochemical properties and appear in the same group (column) of the table. For example, all noble gases are colorless, monatomic gases with very low reactivity. These similarities are due to similar structure in their outer shells of valence electrons. Mendeleev used the prefix eka- for an unknown element below a known one in the same group. See also * Homologous series * Analog Analog or analogue may refer to: Computing and electronics * Analog signal, in which information is enco ...

9-nor-9β-Hydroxyhexahydrocannabinol
9-Nor-9β-hydroxyhexahydrocannabinol (9-Nor-9beta-HHC, sometimes incorrectly confused with 11-nor-9β-hydroxyhexahydrocannabinol),is a cannabinoid first discovered from early modifications to the structure of THC, in a search for the simplest compound that could still fulfill the binding requirements to produce cannabis-like activity. 11-Hydroxyhexahydrocannabinol is the structurally related methylene homologue of 11-Nor-9β-hydroxyhexahydrocannabinol that has been found as a minor active metabolite of tetrahydrocannabinol, and also a metabolite of the trace cannabinoid hexahydrocannabinol.

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 |
Cannabinoid Receptor 1
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] |
Cannabinoid Receptor 2
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Receptor (biochemistry)
In biochemistry and pharmacology, receptors are chemical structures, composed of protein, that receive and transduce signals that may be integrated into biological systems. These signals are typically chemical messengers which bind to a receptor and cause some form of cellular/tissue response, e.g. a change in the electrical activity of a cell. There are three main ways the action of the receptor can be classified: relay of signal, amplification, or integration. Relaying sends the signal onward, amplification increases the effect of a single ligand, and integration allows the signal to be incorporated into another biochemical pathway. Receptor proteins can be classified by their location. Transmembrane receptors include ligand-gated ion channels, G protein-coupled receptors, and enzyme-linked hormone receptors. Intracellular receptors are those found inside the cell, and include cytoplasmic receptors and nuclear receptors. A molecule that binds to a receptor is called a ligand ...

Dissociation Constant
In chemistry, biochemistry, and pharmacology, a dissociation constant (K_D) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its component ions. The dissociation constant is the inverse of the association constant. In the special case of salts, the dissociation constant can also be called an ionization constant. For a general reaction: : A_\mathit B_\mathit \mathit A + \mathit B in which a complex \ce_x \ce_y breaks down into ''x'' A subunits and ''y'' B subunits, the dissociation constant is defined as : K_D = \frac where and ''x'' B''y''are the equilibrium concentrations of A, B, and the complex A''x'' B''y'', respectively. One reason for the popularity of the dissociation constant in biochemistry and pharmacology is that in the frequently encount ...

Cannabinoid
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] |
HU-210
HU-210 is a synthetic cannabinoid that was first chemical synthesis, synthesized in 1988 from (1R,5S)-myrtenol by a group led by Raphael Mechoulam at the Hebrew University. HU-210 is 100 to 800 times more potent than natural Tetrahydrocannabinol, THC from cannabis (drug), cannabis and has an extended duration of action. HU-210 has a binding affinity of 0.061nM at CB1 and 0.52nM at CB2 in cloned human cannabinoid receptors. Compared to Delta-9-THC of 40.7nM at CB1. HU-210 is the (–)-1,1-dimethylheptyl analog of 11-hydroxy- Δ8- tetrahydrocannabinol; in some references it is called 1,1-dimethylheptyl- 11-hydroxytetrahydrocannabinol. The abbreviation "HU" stands for Hebrew University. Effects and research HU-210, the (–) enantiomer of 11-OH-D8-THC-DMH, has almost all of the cannabinoid activity, while the (+) enantiomer, known as HU-211, is inactive as a cannabinoid and instead acts as an NMDA antagonist having neuroprotective effects.
