Cannabis Compound Identification
Common NameCannabinol-C4
DescriptionCannabinol-C4, also known as CBN-C4, belongs to the class of organic compounds known as dibenzopyrans. These are organic heterocyclic compounds with a structure containing a dibenzopyran moiety, made up of two benzene rings fused to a central pyran ring. Cannabinol-C4 also belongs to the class of cannabis compounds known as cannabinols or CBNs. The best known and most abundant CBN is cannabinol or cannabinol-C5 (CBN or CBN-C5). CBN has a 5-carbon aliphatic chain attached to its phenol group, while CBN-C4 has a 4-carbon aliphatic chain. Other CBNs have 1, 2 or 3 carbon atom chains. These shorter chain cannabinols are even less abundant than CBN-C5. Cannabinols are mildly psychoactive cannabinoids found only in trace amounts (PMID: 1221432 ) and are mostly found in aged cannabis (PMID:26870049 ). Pharmacologically relevant quantities are formed as a metabolite of tetrahydrocannabinol (THC) (PMID: 1140243 ). Cannabinols act as partial agonists of the CB1 receptors but tend to have higher affinities to CB2 receptors. The relative activity and CB1/CB2 affinity of CBN-C4 versus CBN-C5 has not been determined. Cannabinol-C4 is one of more than 120 cannabinoid compounds that can be found in cannabis plants (PMID: 6991645 ).
