Application

Iturin A was used in the study of Bacillomycin D (an iturin with antifungal activity against Aspergillus flavus).

Biochem/physiol Actions

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.

Other Notes

A family of lipopeptides characterized by a heptapeptide cyclized with a C13-C17 β-amino fatty acid. Composed mainly of C14-C15 β-amino acids.

Partial least squares (PLS) regression modeling was used to relate the antifungal activity of Bacillus subtilis solid-state fermentation extracts to the individual high-performance liquid chromatography (HPLC) peaks from those extracts. A model was developed that predicted bioassay inhibition based on
