Four cyclic peptides, kapakahines A-D, were isolated from the marine sponge Cribrochalina olemda. Their structures including complete stereochemistry were elucidated by spectral analysis and chemical degradation. The unique structural feature of these peptides is the lack of an amide linkage between two tryptophan residues. Instead the ring is closed by a bond from the indole nitrogen of Trp-1 to the β-carbon of Trp-2.
