- Abstract
- The antifungal antibiotics, neopeptin A, B, C, were found to be cyclic lipopeptides containingunusual amino acids, their structures being elucidated on the basis of chemical and spectroscopic evidence. They inhibited mannoprotein and β-1,3-gllucan synthestases from Saccharomyces cerevisiae. The structure-biological activity relationship is discussed.
