Merine-derived fungi are considered a particularly important group as a source of bioactive natural products. Among the natural products isolated from these fungi, polyketides constitute the largest number of metabolites, which often have biological activities. The objective of this project is to investigate biosynthetic routes of polyketides and alkaloids which have already been isolated (and identified) from marine-derived fungi. Biosynthesis studies of metabolites previously isolated and identified will be carried out using incorporation experiments with 13C labeled precursors for alkaloids and polyketides. The results of the experiments of incorporation will be analyzed by NMR - 13C and high resolution mass spectrometry. (AU)
