CBN was the first cannabinoid to be isolated from cannabis extract in the late 1800s. Specifically, it was discovered by Barlow Wood, Newton Spivey, and Easterfield in 1896. [ 21 ] In the early 1930s, CBN's structure was identified by Cahn , [ 22 ] [ 23 ] marking the first development of a cannabis extract .
Cannabinol (CBN) is a mildly psychoactive cannabinoid that acts as a low affinity partial agonist at both CB1 and CB2 receptors. [ 31 ] [ 32 ] [ 33 ] Through its mechanism of partial agonism at the CB1R, CBN is thought to interact with other kinds of neurotransmission (e.g., dopaminergic, serotonergic, cholinergic, and noradrenergic).
Cannabinoids (/ k ə ˈ n æ b ə n ɔɪ d z ˌ ˈ k æ n ə b ə n ɔɪ d z /) are compounds found in the cannabis plant or synthetic compounds that can interact with the endocannabinoid system. [ 1 ] [ 2 ] The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (Delta-9-THC), the primary intoxicating compound in cannabis .
The use of THC in any capacity may lead to health concerns and users should consult medical personnel before consumption. Local and state laws for use and possession of THC vary by jurisdiction ...
11-Hydroxycannabinol (11-OH-CBN) is the main active metabolite of cannabinol (CBN), one of the active components of cannabis, [1] and has also been isolated from cannabis itself. [2] It is more potent than CBN itself, acting as an agonist of CB 1 with around the same potency as THC , but is a weak antagonist at CB 2 .
Like Δ 9-THC, 11-hydroxy-THC is a partial agonist at the cannabinoid receptor CB 1, but with significantly higher binding affinity (K i = 0.37 nM compared to Δ 9-THC K i = 35 nM). [7] With respect to cAMP inhibition at CB 1 it displays a similar efficacy to that of Δ 9 -THC (EC 50 = 11 nM vs. EC 50 = 5.2 nM, respectively), but a lower ...
The cannabinoid receptor 2 (CB2), is a G protein-coupled receptor from the cannabinoid receptor family that in humans is encoded by the CNR2 gene. [5] [6] It is closely related to the cannabinoid receptor 1 (CB1), which is largely responsible for the efficacy of endocannabinoid-mediated presynaptic-inhibition, the psychoactive properties of tetrahydrocannabinol (THC), the active agent in ...
Nabiximols (brand name Sativex), an oromucosal spray made of a complex botanical mixture containing cannabidiol (CBD), delta-9-tetrahydrocannabinol (THC), and additional cannabinoid and non-cannabinoid constituents from cannabis sativa plants, was approved by Health Canada in 2005, to treat central neuropathic pain in multiple sclerosis, and in ...
