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.
