Abstract
Although Cannabis sativa L. is well known for being prolific in phytocannabinoids, their biosynthetic modular mechanism is ruled by a main enzyme: the geranyltransferase able to pursue the C-isoprenylation of olivetolic acid with the geranyldiphosphate. However, the existence of more than 160 meroterpenoids can be partially explained by a side degree of promiscuity of the geranyltransferase itself, able to recognise different substrate than the ordinary ones. This biological process led to the identification of several unconventional phytocannabinoids with a limited distribution in the plant both for occurrence and concentration. Taking advance of the existing synthetic protocols and using as example the enzymatic promiscuity, we propose a bio-inspired synthesis of naturally occurring minor cannabinoids related to the cannabigerol-type and their preliminary biological inspection in U87, U251 and T98 human glioblastoma cell lines to investigate their potential contribute as supplement in anticancer therapy.
