Cannabidivarin (CBDV) is a non-psychoactive cannabinoid found in Cannabis. It is a homolog of cannabidiol (CBD), with the side-chain shortened by two methylene bridges (CH2 units). Similarly to CBD, it has 7 double bond isomers and 30 stereoisomers (see: Cannabidiol#Double bond isomers and their stereoisomers). It is not scheduled by Convention on Psychotropic Substances. Cannabidivarin (CBDV) suppresses pentylenetetrazole (PTZ)-induced increases in epilepsy-related gene expression. To date, anticonvulsant effects of the plant cannabinoid, cannabidivarin (CBDV), have been reported in several animal models of seizure. However, these behaviourally observed anticonvulsant effects have not been confirmed at the molecular level. Epilepsy is the most prevalent neurological disease and is characterized by recurrent seizures.
