Anwendung
Iturin A was used in the study of Bacillomycin D (an iturin with antifungal activity against Aspergillus flavus).
Biochem./physiol. Wirkung
IturinA exhibits strong antifungal activity against pathogenic yeast and fungi. It interacts with the cytoplasmic membrane of the target cell forming ion conducting pores. Its mode of action could be attributed to its interaction with sterols and phospholipids. The compound causes the release of exo-vesicles from human erythrocytes.
Sonstige Hinweise
