Cannabichromene (CBC), also called cannabichrome, cannanbichromene, pentylcannabichromene or cannabinochromene,^[1] is one of the hundreds of cannabinoids found in the Cannabis plant,^[2] and is therefore a phytocannabinoid. It bears structural similarity to the other natural cannabinoids, including tetrahydrocannabinol (THC), tetrahydrocannabivarin (THCV), cannabidiol (CBD), and cannabinol (CBN), among others.^[2]^[3] CBC and its derivatives are as abundant as cannabinols in cannabis.^[2] 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 200° F, CBCA is decarboxylated, producing CBC. See also the biosynthetic scheme image below.^{[citation needed]}

Pharmacology

As of 2017, CBC is under laboratory research to identify its possible pharmacological properties. No in vivo human studies exist as of 2019.^[1]^[2]^[4]^[5] In vitro, CBC is not active at CB1 or CB2 receptors, but is an agonist of TRPA1 and less potently, an agonist of TRPV3 and TRPV4.^[2] CBC has two stereoisomers.
