Four new compounds (1-4) together with six known compounds (5-10) were isolated from the leaf extract of Garcinia nigrolineata. Compound 4 is a rare tocotrienol quinone dimer. The structures were elucidated based on NMR and MS data. All isolated compounds were evaluated for their antibacterial activities.

Article Synopsis
  • * This study introduces a new strategy that uses a chemosynthesis-like method to emphasize the value of biobased intermediates, specifically focusing on geranylgeraniol (GGOH) production.
  • * Through advanced metabolic engineering and a novel yeast strain, researchers achieved significant GGOH production, which led to the semi-synthesis of several pharmaceuticals, suggesting new possibilities for industrial production improvements and innovations.

Chlorophyll degradation causes the release of phytol, which is converted into phytyl diphosphate (phytyl-PP) by phytol kinase (VITAMIN E PATHWAY GENE5 [VTE5]) and phytyl phosphate (phytyl-P) kinase (VTE6). The kinase pathway is important for tocopherol synthesis, as the Arabidopsis (Arabidopsis thaliana) vte5 mutant contains reduced levels of tocopherol. Arabidopsis harbors one paralog of VTE5, farnesol kinase (FOLK) involved in farnesol phosphorylation.
