Popis: | Chemical profiling of extracts from a mud dauber wasp-associated fungus, Aspergillus sp. (CMB-W031), revealed a remarkably diverse array of secondary metabolites, with many biosynthetic gene clusters being transcriptionally responsive to specific culture conditions. Chemical fractionation of a jasmine rice cultivation yielded many known fungal metabolites, including the highly cytotoxic (-)-stephacidin B and an unprecedented nonribosomal peptide synthase derived nitro depsi-tetrapeptide diketopiperazine, waspergillamide A (1). All structures were assigned by detailed spectroscopic analysis and, where appropriate, chemical degradation and Marfey's analysis. |
