Determination of absolute structures of cyclic peptides, PF1171A and PF1171C, from unidentified ascomycete OK-128.
Two cyclic peptides, PF1171A (1) and PF1171C (2), were isolated from okara that had been fermented with unidentified ascomycete OK-128. Their absolute configurations were determined by Marfey's method. These peptides showed paralytic activity against silkworms.
