- Abstract
A novel lumazine peptide, aspergilumamide A ( 1), as well as a known analog penilumamide ( 2), were isolated from the mycelia of a marine-derived fungus Aspergillus sp. (33241), obtained from the mangrove Bruguiera sexangula var. rhynchopetala collected from the South China Sea. The structure of 1 was identified by comprehensive spectroscopic analysis, including 1D- and 2D-NMR, ESI-MS, and MS/MS experiments. The absolute configuration of 1 was determined by Marfey's method.
