HHC-P is a partial agonist of the CB1 receptors with an EC50 of 44.4nM for 9R-HHCP and 134nM for 9S-HHCP. Compared to Hexahydrocannabinol (HHC) with an EC50 of 101nM for 9R-HHC and 1,190nM for 9S-HHC [ 5 ] In 2021, HHC-P was positively identified in multiple retail electronic vaping products in the United States.
Hexahydrocannabinol (HHC) is a hydrogenated derivative of tetrahydrocannabinol (THC). It is a naturally occurring phytocannabinoid that has rarely been identified as a trace component in Cannabis sativa, [1] [2] but can also be produced synthetically by firstly acid cyclization of cannabidiol and then hydrogenation of tetrahydrocannabinol.
Hexahydrocannabihexol (HHCH) is a semi-synthetic cannabinoid derivative. It was first synthesised by Roger Adams in 1942 and found to be more potent than either the pentyl or heptyl homologues, or the unsaturated tetrahydrocannabinol analogue. [1] [2] HHCH was first identified as a designer drug in Sweden in September 2023. [3]
Hexahydrocannabutol (HHCB, HHC-B) is a semi-synthetic cannabinoid derivative, the hydrogenated derivative of tetrahydrocannabutol (THCB). It was first synthesised by Roger Adams in 1942 and produces only weak cannabinoid-like effects in animals. [1] More recently it has been sold as an ingredient in grey-market cannabinoid products. [2]
Cannabinoids, including tetrahydrocannabinol (THC), the active drug in cannabis, can also be produced by bioengineered yeast, a process colloquially known as pharming. [1] In 2007, a research group reported the successful transgenic placement of a THCA synthase gene from Cannabis plant into the Pichia pastoris yeast, giving the yeast the ability to turn the precursor molecule cannabigerolic ...
Four stereoisomers of 8-OH-HHC arise from C8-hydroxylation of hexahydrocannabinol. There are four possible 8-OH-HHC metabolites arising from naturally derived HHCs: cis-and trans-8-OH-9α-HHC & cis-and trans-8-OH-9β-HHC. All four have been prepared synthetically to probe stereochemical effects on cannabinoid biological activity. [5]
The Δ 9 isomer of THCP occurs naturally in cannabis, but in small amounts.A 2021 study reported the content of Δ 9-THCP ranging from 0.0023% to 0.0136% (w/w) (approximately 0.02–0.13 mg/g) without correlation to THC percentage in Δ 9-THC-dominant strains of cannabis; that study failed to detect THCP in CBD-dominant strains.
9-Nor-9β-hydroxyhexahydrocannabinol (9-nor-9beta-HHC; sometimes incorrectly confused with 11-nor-9β-hydroxyhexahydrocannabinol [1]) 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.
