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.Script error: No such module "Unsubst".
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]Script error: No such module "Unsubst". 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.
