title: Chrysospermins, new peptaibol antibiotics from Apiocrea chrysosperma Ap101.
abstract: Four new members of peptaibol antibiotics, designated as chrysospermins A, B, C, and D, were isolated from the mycelium of Apiocrea chrysosperma Ap101 by solvent extraction, silica gel chromatography and preparative recycling HPLC. Their structures as new nonadecapeptides were settled by detailed spectroscopic analysis and chemical degradation experiments. The chrysospermins display antibacterial and antifungal activity, and induce pigment formation by the fungus Phoma destructiva.
