一般描述

两性霉素B是一种大环内酯,具有亲水性多羟基链和亲脂性多烯烃链。

应用

两性霉素B溶液已被用于:
  • 作为腹腔注射剂用于治疗烟曲霉感染小鼠
  • 作为中国美利奴绵羊卵巢培养的理想培养基的组成部分
  • 在收集马黄体时用作运输培养基中的组成成分
  • 作为RPMI培养基中的补充剂,用于培养小鼠-小鼠B细胞杂交瘤55-6细胞系

生化/生理作用

两性霉素B对真菌和酵母最有效。它通过结合与膜相关的固醇而形成跨膜通道,从而导致小分子的泄漏。尽管两性霉素B是治疗真菌病的有效抗生素,它会引起毒性。
两性霉素B是一种来自链霉菌的多烯抗真菌抗生素,临床上用于治疗系统性真菌感染。它对真菌和细菌细胞膜的固醇,尤其是麦角固醇具有很高的亲和力。 维持抗真菌细胞培养的正常用量为2.5 mg/L,同时在培养基中使用青霉素和链霉素。

包装

20、50、100 ml

组分

该产品以250 μg/mL溶于去离子水中的两性霉素B提供。它是一种含有两性霉素B和以下提高其溶解度的组分组成的溶液:脱氧胆酸钠、氯化钠和磷酸钠。

注意

两性霉素B在37°C的培养条件下可保持活性3天。

制备说明

其在水溶液中形成沉淀是正常现象。 对溶液进行混合可重新溶解大部分沉淀物,但是,如果无法完全溶解,两性霉素B仍然适合使用。
