O-1871
O-1871 is a potent cannabinoid agonist which was invented by Billy R Martin and Raj K Razdan at Organix Inc in 2002. It has a CB1 receptor affinity of 2.0nM and a CB2 receptor affinity of 0.3nM. Structurally, O-1871 is a cyclohexylphenol derivative related to CP 47,497, and so is illegal in some jurisdictions where CP 47,497 and its derivatives are banned. However the 3,3-dimethylcyclohexyl substituent of O-1871 can be replaced by various other groups, producing other potent compounds such as the cycloheptyl derivative O-1656 and the 2-adamantyl derivative O-1660, as well as the corresponding 3,5-dichlorophenyl derivative, which are not cyclohexylphenol derivatives. ] ] See also * CP 55,940 * Cannabidiol * Cannabicyclohexanol Cannabicyclohexanol (CCH, CP 47,497 dimethyloctyl homologue, (C8)-CP 47,497) is a cannabinoid receptor agonist drug, developed by Pfizer in 1979.

CP 47,497
CP 47,497 or (C7)-CP 47,497 is a cannabinoid receptor agonist drug, developed by Pfizer in the 1980s. It has analgesic effects and is used in scientific research. It is a potent CB1 agonist with a ''K''d of 2.1 nM. Homologue On the 19th of January 2009, the University of Freiburg in Germany announced that an analog of CP 47,497 is the main active ingredient in the herbal "incense" product Spice, specifically the 1,1-dimethyloctyl homologue of CP 47,497. Both the dimethylheptyl and dimethyloctyl homologues were detected in different batches, with considerable variation in the concentration present in different samples that were analysed. The weaker dimethylhexyl and dimethylnonyl homologues were not found in any batches of smoking blends tested, but have been legally scheduled alongside the others in some jurisdictions, to forestall any potential use for this purpose. The 1,1-dimethyloctyl homologue of CP 47,497 is several times more potent than the parent compound, which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
O-1656
O-1656 is a cannabinoid agonist which was invented by Billy R Martin and Raj K Razdan at Organix Inc in 2002. It is moderately selective for the CB2 receptor with a CB1 receptor affinity of 18 nM and a CB2 receptor affinity of 2 nM. Since it has a cycloheptyl ring attached to the phenol core, it falls outside the definition of a "cyclohexylphenol derivative", but may still be controlled by generic legislation in some jurisdictions.

Cannabicyclohexanol
Cannabicyclohexanol (CCH, CP 47,497 dimethyloctyl homologue, (C8)-CP 47,497) is a cannabinoid receptor agonist drug, developed by Pfizer in 1979. On 19 January 2009, the University of Freiburg in Germany announced that an analog of CP 47,497 was the main active ingredient in the herbal incense product ''Spice'', specifically the 1,1-dimethyloctyl homologue of CP 47,497, which is now known as cannabicyclohexanol. The 1,1-dimethyloctyl homologue of CP 47,497 is in fact several times more potent than the parent compound, which is somewhat unexpected as the 1,1-dimethylheptyl is the most potent substituent in classical cannabinoid compounds such as HU-210. Enantiomers Cannabicyclohexanol has four enantiomers, which by analogy with other related cannabinoid compounds can be expected to have widely varying affinity for cannabinoid receptors, and consequently will show considerable variation in potency. While the (-)-''cis'' enantiomer (-)-cannabicyclohexanol discovered in the original ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabinor
Cannabinor (PRS-211,375) is a drug which acts as a potent and selective cannabinoid CB2 receptor agonist. It is classed as a "nonclassical" cannabinoid with a chemical structure similar to that of cannabidiol. It has a CB2 affinity of 17.4nM vs 5585nM at CB1, giving it over 300x selectivity for CB2. It showed analgesic effects in animal studies especially in models of neuropathic pain, but failed in Phase IIb human clinical trials due to lack of efficacy.

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] |
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] |

CP 55,940
55,940 is a synthetic cannabinoid which mimics the effects of naturally occurring THC (one of the psychoactive compounds found in cannabis). CP 55,940 was created by Pfizer in 1974 but was never marketed. It is currently used to study the endocannabinoid system. A study found that CP 55,940 can upregulate 5-HT2A receptors in mice. CP 55,940 is 45 times more potent than Δ9-THC, and fully antagonized by rimonabant (SR141716A). CP 55,940 is considered a full agonist at both CB1 and CB2 receptors and has Ki values of 0.58 nM and 0.68 nM respectively, but is an antagonist at GPR55, the putative "CB3" receptor. CP 55,940 showed protective effects on rat brain mitochondria upon paraquat exposure. It also showed neuroprotective effects by reducing intracellular calcium release and reducing hippocampal cell death in cultured neurons subjected to high levels of NMDA. CP 55,940 induced cell death in NG 108-15 Mouse neuroblastoma x Rat glioma hybrid brain cancer (geneticall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
