Abstract

In the course of our chemical screening program for novel metabolites by LC-MS monitoring, we isolated a new aspochracin derivative, JBIR-15 (1), together with aspochracin, from the culture broth of a sponge-derived fungus, Aspergillus sclerotiorum Huber Sp080903f04. The structure of 1 was determined to be N-demethyl aspochracin at the alanyl residue on the basis of extensive NMR and MS analyses.
