Abstract

Terpeptin A (1) and B (2), two new members of the indolic enamides, along with three known compounds (3–5) were identified from a strain of Aspergillus sp. (w‐6), an endophytic fungus associated with Acanthus ilicifolius. The complete ^1^H and ^13^C NMR assignments for these compounds were carried out using ^1^H, ^13^C, DEPT, COSY, HMQC, and HMBC NMR experiments. Terpeptin A and B exhibited modest cytotoxicity against A‐549 cell line. Copyright © 2008 John Wiley & Sons, Ltd.
