General description

该产品是约 2.5% 匹马菌素的盐水悬浮液γ-经过辐照

匹马菌素是一种多烯类抗真菌抗生素,由南非彼得马里茨堡附近土壤中的纳塔尔链霉菌产生。1 匹马菌素具有与制霉菌素相似的抗菌活性。此外,它对阴道毛滴虫有活性。 匹马菌素用于治疗念珠菌病、滴虫病、真菌性角膜炎和曲霉病。 在一些国家它也被用作食品添加剂。一些研究表明它可以减少与屋尘螨相关的霉菌数量。2

Application

匹马菌素是一种来自纳塔尔链霉菌恰塔努加链霉菌的两性抗生素。它用于多种真菌感染,主要为外用。 它可用作麦角固醇和胆固醇结合剂,用于研究脂质双层动力学,尤其是在真菌细胞中。 它用于研究匹马菌素的生物合成,并作为琼脂培养基中的杀菌剂

Biochem/physiol Actions

与麦角甾醇特异性结合并阻断真菌生长的抗真菌多烯大环内酯。 然而,与制霉菌素和菲律宾菌素不同,匹马菌素不会改变质膜的通透性。

Preparation Note

产品不会因单次冻融循环而降解。 稀释后的产品应分装并冷冻保存。
该产品也可用 0.5 M 氯化钠进一步稀释为悬浮液。该产品也可以进一步在二甲基甲酰胺等有机溶剂中稀释(也可溶于DMSO)。

该产品和任何水性稀释液将是悬浮液,不应无菌过滤。

Other Notes

20ml
保存于密闭容器内,置于干燥通风处。打开后的容器必须小心重新密封并保持直立以防止泄漏。对光敏感
