Cannabimovone, a Cannabinoid with a Rearranged Terpenoid Skeleton from Hemp

“An investigation of the polar fractions from a nonpsychotropic variety of hemp (Cannabis sativa L.) afforded cannabimovone, a polar cannabinoid with a rearranged 2(34) abeo-terpenoid skeleton, biogenetically originating from the intramolecular aldolization of a 2′,3′-seco-menthanyl precursor.

The structure of cannabimovone was elucidated by spectroscopic analysis, whereas attempts to mimic its biogenetic derivation from cannabidiol gave only anhydrocannabimovone, the intramolecular oxy-Michael adduct of the crotonized version of the elusive natural products.

Biological evaluation of cannabimovone against metabotropic (CB1, CB2) and ionotropic (TRPs) cannabinoid receptors showed a significant activity only for ionotropic receptors, especially TRPV1, whereas anhydrocannabimovone exhibited strong activity at both ionotropic and metabotropic cannabinoid receptors.

Overall, the biological profile of anhydrocannabimovone was somewhat similar to that of THC, suggesting a remarkable tolerance to constitutional and configurational changes.”
