THC is tetrahydrocannabinol, the main active chemical compound in cannabis.
Tetrahydrocannabinol (THC) is one of at least 113 cannabinoids identified in cannabis. THC is the principal psychoactive constituent of cannabis. With chemical name (−)-trans-Δ⁹-tetrahydrocannabinol, the term THC also refers to cannabinoid isomers.
A cannabinoid is one of a class of diverse chemical compounds that acts on cannabinoid receptors in cells that alter neurotransmitter release in the brain. Ligands for these receptor proteins include the endocannabinoids, the phytocannabinoids, and synthetic cannabinoids. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC), the primary psychoactive compound in cannabis. Cannabidiol (CBD) is another major constituent of the plant. There are at least 113 different cannabinoids isolated from cannabis, exhibiting varied effects.
Cannabinol (CBN) is a non-psychoactive cannabinoid found only in trace amounts in Cannabis, and is mostly found in aged Cannabis. Pharmacologically relevant quantities are formed as a metabolite of tetrahydrocannabinol (THC). CBN acts as a partial agonist at the CB1 receptors, but has a higher affinity to CB2 receptors; however, it has lower affinities relative to THC. Degraded or oxidized cannabis products, such as low-quality baled cannabis and traditionally produced hashish, are high in CBN.
Cannabidiol (CBD) is a phytocannabinoid discovered in 1940. It is one of some 113 identified cannabinoids in cannabis plants, accounting for up to 40% of the plant's extract. As of 2018, preliminary clinical research on cannabidiol included studies of anxiety, cognition, movement disorders, and pain.
Tetrahydrocannabivarin is a homologue of tetrahydrocannabinol (THC) having a propyl (3-carbon) side chain instead of a pentyl (5-carbon) group on the molecule, which makes it produce very different effects from THC.
THC-O-phosphate is a water-soluble organophosphate ester derivative of THC, which functions as a metabolic prodrug for THC itself. It was invented in 1978 in an attempt to get around the poor water solubility of THC and make it easier to inject for the purposes of animal research into its pharmacology and mechanism of action. The main disadvantage of THC phosphate ester is the slow rate of hydrolysis of the ester link, resulting in delayed onset of action and lower potency than the parent drug. Pharmacologically, it parallels the action of psilocybin as a metabolic prodrug for psilocin.
Parahexyl is a synthetic homologue of THC, which was invented in 1949 during attempts to elucidate the structure of Δ9-THC, one of the active components of cannabis.
THC acetate ester is the acetate ester of THC. It acts as a metabolic prodrug for THC itself, and chemically works the same way that heroin does as a metabolic prodrug for morphine. It has been reported to be approximately two times as potent as THC to approximately three times as potent as THC with a unique psychedelic high described as follows.
"The effect of the acetate is more spiritual and psychedelic than that of the ordinary product. The most unique property of this material is that there is a delay of about thirty minutes before its effects are felt."
11-Hydroxy-Δ9-tetrahydrocannabinol (11-OH-THC), usually referred to as 11-hydroxy-THC, is the main active metabolite of tetrahydrocannabinol (THC), which is formed in the body after decarboxylated cannabis is consumed.
Dimethylheptylpyran is a synthetic analogue of THC, which was invented in 1949 during attempts to elucidate the structure of Δ9-THC, one of the active components of cannabis. DMHP is a pale yellow, viscous oil which is insoluble in water, but dissolves in alcohol or non-polar solvents.
Tetrahydrocannabinol-C4, also known as THC-C4 and butyl-THC, is a homologue of tetrahydrocannabinol (THC), the active component of cannabis. They are only different by the pentyl side chain being replaced by a butyl side chain. It is unknown whether THC-C4 is an agonist, partial agonist, or antagonist at the cannabinoid receptors. The propyl analog, THCV, is a cannabinoid receptor type 1 and cannabinoid receptor type 2 antagonist, while THC is a CB1 agonist. THC-C4 has rarely been isolated from cannabis samples, but appears to be less commonly present than THC or THCV. It is metabolised in a similar manner to THC. Similarly to THC, it has 7 double bond isomers and 30 stereoisomers.
11-Nor-9-carboxy-Δ9-tetrahydrocannabinol, often referred to as 11-nor-9-carboxy-THC or THC-11-oic acid, is the main secondary metabolite of tetrahydrocannabinol (THC), which is formed in the body after cannabis is consumed.
AM-087 (part of the AM cannabinoid series) is an analgesic drug which acts as a cannabinoid agonist. It is a derivative of Δ8THC substituted on the 3-position side chain. AM-087 is a potent CB1 agonist with a Ki of 0.43nM, making it around 100x more potent than THC itself. This is most likely due to the bulky bromine substituent on the side chain.
Liquiritigenin is a flavanone that was isolated from Glycyrrhiza uralensis, and is found in a variety of plants, including Glycyrrhiza glabra (licorice). It is an estrogenic compound which acts as a selective agonist of the ERβ subtype of the estrogen receptor (ER), though it is also reported to act as an ERα partial agonist at sufficient concentrations. It also has a choleretic effect.
Methylpiperidinopyrazole (MPP) is a synthetic, nonsteroidal, and highly selective antagonist of ERα that is used in scientific research to study the function of this receptor. It has 200-fold selectivity for ERα over ERβ and 1000-fold selectivity for blocking ERα-mediated gene transcription relative to that of ERβ.
PHTPP is a synthetic, nonsteroidal, and highly selective antagonist of ERβ that is used in scientific research to study the function of this receptor. It possesses 36-fold selectivity for ERβ over ERα, and is a silent antagonist of ERβ.
