New Cyclic Peptide and Bisindolyl Benzenoid Metabolites from the Sclerotia of <i>Aspergillus sclerotiorum</i>

Abstract

Scleramide (1), a new cyclic hexapeptide, and a new oxidized bisindolyl benzenoid derivative (2' '-oxoasterriquinol D methyl ether, 2) were isolated from extracts of the sclerotia of Aspergillus sclerotiorum (NRRL 5167). The structures of these compounds were determined by analysis of 1D and 2D NMR experiments.
