Hexahydrocannabiphorol (HHCP, sometimes mistakenly referred to as hexahydroxycannabiphorol) is a semi-synthetic cannabinoid derivative which has been marketed since around 2021. [1] [2] It is believed to be made from the hydrogenation of tetrahydrocannabiphorol (THCP). THCP is only reported as a trace component of cannabis in 2019. [3] HHCP was studied by Roger Adams as early as 1942. [4]

Pharmacology

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. [1]

Legality

The legal status of hexahydrocannabinol and derivatives varies between countries, leading to widespread sale in some jurisdictions in Europe and the US.

In France, HHCP was banned in 2023. [6]

In Japan, Japanese Health Ministry announced that six synthetic cannabinoids with structures similar to HHCH, including HHCP, were to be banned from 6 January 2024 [7]

HHCP was banned in Slovakia as of 13 January 2024.[ citation needed ]

THC-O-acetate is the acetate ester of THC. The term THC-O-acetate and its variations are commonly used for two types of the substance, dependent on which cannabinoid it is synthesized from. The difference between Δ8-THC and Δ9-THC is bond placement on the cyclohexene ring.

Dimethylheptylpyran (DMHP) is a synthetic cannabinoid and analogue of tetrahydrocannabinol (THC). It 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.

Δ9-Tetrahydrocannabutol is a phytocannabinoid found in cannabis that is a homologue of tetrahydrocannabinol (THC), the main active component of Cannabis. Structurally, they are only different by the pentyl side chain being replaced by a butyl side chain. THCB was studied by Roger Adams as early as 1942

JWH-018 (1-pentyl-3-(1-naphthoyl)indole, NA-PIMO or AM-678) is an analgesic chemical from the naphthoylindole family that acts as a full agonist at both the CB1 and CB2 cannabinoid receptors, with some selectivity for CB2. It produces effects in animals similar to those of tetrahydrocannabinol (THC), a cannabinoid naturally present in cannabis, leading to its use as synthetic cannabinoid products that, in some countries, are sold legally as "incense blends".

UR-144 (TMCP-018, KM-X1, MN-001, YX-17) is a drug invented by Abbott Laboratories, that acts as a selective full agonist of the peripheral cannabinoid receptor CB2, but with much lower affinity for the psychoactive CB1 receptor.

<span class="mw-page-title-main">AM-2389</span> Chemical compound

AM-2389 is a classical cannabinoid derivative which acts as a potent and reasonably selective agonist for the CB1 receptor, with a Ki of 0.16 nM, and 26× selectivity over the related CB2 receptor. It has high potency in animal tests of cannabinoid activity, and a medium duration of action. Replacing the 1',1'-dimethyl substitution of the dimethylheptyl side chain of classical cannabinoids with cyclopropyl or cyclopentyl results in higher potency than cyclobutyl, but only the cyclobutyl derivatives show selectivity for CB1 over CB2. High selectivity for CB1 over CB2 is difficult to achieve (cf. AM-906, AM-1235), as almost all commonly used CB1 agonists have similar or greater affinity for CB2 than CB1, and the only truly highly selective CB1 agonists known as of 2012 are eicosanoid derivatives such as O-1812.

In 2021, MDMB-4en-PINACA was the most common synthetic cannabinoid identified by the Drug Enforcement Administration in the United States. MDMB-4en-PINACA differs from 5F-MDMB-PINACA due to replacement of 5-fluoropentyl with a pent-4-ene moiety (4-en).

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, but can also be produced synthetically by firstly acid cyclization of cannabidiol and then hydrogenation of tetrahydrocannabinol.

<span class="mw-page-title-main">ADB-FUBIATA</span> Chemical compound

ADB-FUBIATA (AD-18, FUB-ACADB, ADB-FUBIACA) is a synthetic cannabinoid compound first identified in 2021. It is closely related in structure to the older compound ADB-FUBICA but with the amide linker group extended by the addition of a methylene bridge. It started to be sold as an ingedient in grey-market synthetic cannabis blends following the introduction of legislation in China which for the first time introduced general controls on various classes of synthetic cannabinoids, but did not encompass compounds where the linker group had been extended in this fashion. ADB-FUBIATA has many times lower affinity for cannabinoid receptors than ADB-FUBICA with an EC50 of only 635 nM at CB1, but retains full agonist activity at this target, while being practically inactive at CB2.
