Culicinin D (1), a 10 aminoacid peptaibol containing several unusual residues, has been shown to exhibit potent anticancer activity. Previous work in our group towards developing a structure-activity relationship (SAR) for this peptaibol has concentrated on replacement of the synthetically challenging AHMOD (3) and AMD (4) residues, resulting in the discovery of analogues with equivalent or better
The peptideantibioticstrichopolynI and II produced by Trichodermapolysporum were shown by chemical degradation and spectral analysis to have the structure (14) and (15) respectively.
