Cannabichromene (CBC), also called cannabichrome, cannanbichromene, pentylcannabichromene or cannabinochromene, [1] exhibits anti-inflammatory properties in vitro, which may, theoretically, contribute to cannabis analgesic effects. [2] It is a phytocannabinoid, one of the hundreds of cannabinoids found in the Cannabis plant. [3] It bears structural similarity to the other natural cannabinoids, including tetrahydrocannabinol (THC), tetrahydrocannabivarin (THCV), cannabidiol (CBD), and cannabinol (CBN), among others. [3] [4] It is not scheduled by the Convention on Psychotropic Substances.

Biosynthesis

Within the Cannabis plant, CBC occurs mainly as cannabichromenic acid (CBCA, 2-COOH-CBC, CBC-COOH). Geranyl pyrophosphate and olivetolic acid combine to produce cannabigerolic acid (CBGA; the sole intermediate for all other phytocannabinoids), which is cyclized by the enzyme CBCA synthase to form CBCA. Over time, or when heated above 93 °C, CBCA is decarboxylated, producing CBC. See also the biosynthetic scheme image below.[ citation needed ]

Pharmacology

Cannabichromene has been hypothesized to affect THC psychoactivity, though in vivo effects have not been demonstrated. [5] CBC acts on the TRPV1 and TRPA1 receptors, interfering with their ability to break down endocannabinoids (chemicals such as anandamide and 2-AG that the body creates naturally). [6] [ unreliable source? ] CBC has shown antitumor effects in breast cancer xenoplants in mice. [7] It also has anticonvulsant activity in a mouse model. [8]

In vitro , CBC binds weakly to CB1 and CB2 with binding affinities of 713 nM and 256 nM, respectively, which are significantly lower than that for THC with 35 nM at CB1. [9] [10] acting as an agonist for cAMP stimulation and an antagonist at beta-arrestin. [9] Additionally, CBC is an agonist of TRPA1, and less potently TRPV3 and TRPV4. [3] CBC has two stereoisomers.
