A detailed chemical investigation of the mycelial extract of the endophytic fungus Aureobasidium pullulans isolated from leaves of the Moroccan Aloe vera yielded one new amide pestalotiopamide E (1) and its corresponding new acid pestalotiopin B (2) together with two indole metabolites (3 and 4), isoochracinic acid (5) and two hydronaphthalene derivatives (6 and 7). All isolated compounds were tested...
Chemical investigation of the endophytic fungus Talaromyces wortmannii, isolated from Aloe vera, yielded two new cyclic peptides, talaromins A and B. Their structures were established on the basis of extensive NMR spectroscopic and mass spectrometric analysis. Both cyclopeptides contain ring systems comprised of six α-amino acid residues connected to a β-amino acid. The absolute configurations of...
