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.
