Four new cyclic decapeptides, auyuittuqamides A–D (14), were obtained from Sesquicillium microsporum RKAG 186 obtained from marine sediment collected from the intertidal zone of Frobisher Bay, Nunavut, Canada. The structures of the compounds were elucidated by NMR spectroscopy and tandem mass spectrometry. The absolute configurations of the amino acids were determined using Marfey’s method.
