Fig. 1 in Biosynthetic origins of unusual cannabimimetic phytocannabinoids in Cannabis sativa L: A review

Fig. 1. Topological arrangement and structural relationships of alkyl phytocannabinoids. (a) Alkyl phytocannabinoid isoprenyl subclasses and biosynthetic relationships. (b) Major pharmacophore and common structural features between the phytocannabinoid Δ 9-THC and the endocannabinoid anandamide (N-arachidonoylethanolamine; AEA).Compound subclass abbreviations: CBC - cannabichromene; CBD - cannabidiol; CBE - cannabielsoin; CBF - cannabifuran; CBG - cannabigerol; CBL - cannabicyclol; CBN - cannabinol; CBND - cannabinodiol; THC – Δ9 tetrahydrocannabinol; red colour phytocannabinoid moieties derived from a = resorcinol origin, blue colour = phytocannabinoid moieties derived from an isoprenoid origin. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
