Cannabichromene (CBC) is one of the 120 cannabinoids found in the Cannabis plant, and therefore can be also described as a phytocannabinoid – from ancient Greek phyton = “plant”. It bears structural similarity to the other natural cannabinoids, including tetrahydrocannabinol, tetrahydrocannabivarin, cannabidiol, and cannabinol, among others. Cannabichromene and its derivatives are as abundant as cannabinols in cannabis. It is not active at CB1 or CB2 receptors, but is an agonist of TRPA1 and less potently, an agonist of TRPV3 and TRPV4. CBC has two stereoisomers. It is not scheduled by the Convention on Psychotropic Substances.
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 (a key intermediate for multiple cannabinoids), which is cyclized by the enzyme CBCA synthase to give CBCA. Over time, or when heated, CBCA is decarboxylated, producing CBC. See biosynthetic scheme below the chemical data table.
