Activation of CB2 Receptors by (−)-Cannabichromene but Not (+)-Cannabichromene

Cannabichromene (CBC) is a minor constituent of cannabis that is a selective cannabinoid CB2 receptor agonist and activator of TRPA1. To date, it has not been shown whether (-)-CBC, (+)-CBC, or both can mediate these effects. In this study, we investigate the activity of the CBC enantiomers at CB1, CB2, and Transient receptor potential ankyrin 1 (TRPA1) receptors
