<jats:title>Abstract</jats:title><jats:p>Two new cyclic pentapeptides, named versicotides A (<jats:bold>1</jats:bold>) and B (<jats:bold>2</jats:bold>), were obtained from a marine‐derived fungus strain ZLN‐60, identified as <jats:italic>Aspergillus versicolor.</jats:italic> Their structures were established on the basis of chemical and spectroscopic evidence. Versicotides are new cyclic pentapeptides which contain an <jats:sc>L</jats:sc>‐alanine residue, two anthranilic acid (=2‐aminobenzoic acid) residues, and two <jats:italic>N</jats:italic>‐methyl‐<jats:sc>L</jats:sc>‐alanine residues. Antitumor activities were evaluated by the SRB and MTT methods.
