Biomimetic synthesis of rare cannabigerol-type cannabinoids and evaluation of their cytotoxic effect on human glioblastoma cell lines.

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.

Untargeted metabolomics profiling of Morus alba twigs extract and antibacterial activity of pure metabolites.

Plant natural products offer promise in combating multi-drug resistance by acting as antibacterial agents through various mechanisms. A metabolomic-guided phytochemical investigation, based on a LC-HRMS/MS and Molecular Networking combined approach, was carried out on an extract of M. alba L.

Metabolites from Aerial Parts of as Modulators of Targets Related to Metabolic Syndrome.

A detailed phytochemical investigation has been carried out on the aerial parts of leading to the isolation of 29 pure compounds, mainly belonging to the amorfrutin and polyphenol classes. Among them, the new amorfrutin N () and exiguaflavone L () were isolated and their structures elucidated by means of HR-ESIMS and NMR. All the isolated compounds were investigated for modulation of mitochondrial activity and stimulation of glucose uptake via GLUT transporters, two metabolic processes involved in intracellular glucose homeostasis, which, therefore, correlate with the incidence of metabolic syndrome.

Effect of saline irrigation and plant-based biostimulant application on fiber hemp ( L.) growth and phytocannabinoid composition.

Phytocannabinoids represent the hallmark of the secondary metabolism of . The content of major phytocannabinoids is closely related to genetic variation as well as abiotic elicitors such as temperature, drought, and saline stress. The present study aims to evaluate hemp response to saline irrigation supplied as NaCl solutions with an electrical conductivity (EC) of 2.
