应用
伊枯草菌素A 用于 Bacillomycin D(一种具有抗黄曲霉抗真菌活性的 伊枯草菌素)的研究
生化/生理作用
伊枯草菌素A 对致病性酵母和真菌有很强的抗真菌活性。它与靶细胞的细胞质膜相互作用,形成离子传导孔。其作用方式可归因于其与固醇和磷脂的相互作用。该化合物导致人红细胞释放外囊泡(exo-vesicle)。

The removal of many synthetic fungicides from the market has created a demand for new, environmentally safe fungicides. Iturin A, a cyclic lipopeptide produced by Bacillus subtilis, has strong antifungal properties and low mammalian toxicity. To determine the efficacy of
Journal of agricultural and food chemistry, 55(23), 9530-9536 (2007-10-24)
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
FEBS letters, 584(14), 3209-3214 (2010-06-15)
Subtulene A, a new cyclic lipopeptide, was isolated from the culture broth of Bacillus subtilis SSE4. This antibiotic compound contained the seven common alpha-amino acids, L-Asn-1, D-Tyr-2, D-Asn-3, L-Gln-4, L-Pro-5, D-Asn-6, L-Ser-7 and the unique beta-amino acid-8 present in the
