说明

纳他霉素是一种多烯类抗生素，通常用作抗真菌剂，因为它缺乏耐药性，具有广泛的活性。然而，它的作用模式尚不清楚，直接结合和等温滴定量热法研究表明，纳他霉素与模型膜中存在的麦角甾醇特异性结合。
纳他霉素对霉菌和酵母菌都有活性。它在食品工业中用作杀菌剂和抗生素防腐剂。
纳他霉素可作为分析参考标准，用于使用高性能液相色谱法（HPLC-ESI-HR-MS）和反相高效液相色谱串联质谱技术（UHPLC-MS/MS）对葡萄酒样品中的分析物进行定量。

一般描述

Natamycin is a polyene antibiotic that generally finds application as an antifungal agent as it lacks development of resistance and has a broad spectrum of activity. However, its mode of action is yet unclear, direct binding and isothermal titration calorimetry studies has revealed that natamycin binds specifically to ergosterol present in model membranes.

Natamycin shows activity against both molds and yeasts. It finds applications as a fungicidal and antibiotic preservative in the food industry.

应用

Natamycin may be used as an analytical reference standard for the quantification of the analyte in wine samples using high-performance liquid chromatography coupled to electrospray ionization in positive mode high resolution mass spectrometry (HPLC-ESI-HR-MS) and reversed-phase high-performance liquid chromatography-tandem mass spectrometry technique (UHPLC-MS/MS).

生化/生理作用

与麦角固醇特异性结合并阻止真菌生长的抗真菌多烯大环内脂。但不同于制霉菌素和菲律宾菌素不同，那他霉素不会改变细胞质膜的渗透性
