Abstract:As part of a study examining polar metabolites produced by cyanobacterial strains, we examined media extracts of a Calothrix sp. (strain R-3-1) and a Scytonema sp. (strain U-3-3). The cell mass of each was separated from the media, and HP20 resin was added for adsorption of secreted metabolites, a relatively unexplored area of cyanobacterial chemistry. HPLC-UV-LCMS-guided isolation led to the discovery of seven sesquiterpenoid compounds with five new, one known, and one previously isolated as the methyl ester.… Show more
“…106 Three eudesmane-type sesquiterpenes 261 – 263 were isolated from media extracts of Scytonema sp. 107 While these sesquiterpene NPs are typically reported from fungi, no attempt was made to show the presence of the compounds in the cyanobacterial cell mass.…”
