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。

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

A chemically novel autoinducer (PI factor) has been purified from cultures of the pimaricin producer Streptomyces natalensis ATCC27448. The chemical structure of the PI molecule was identified as 2,3-diamino-2,3-bis (hydroxymethyl)-1,4-butanediol. Pimaricin biosynthesis in S. natalensis npi287, a mutant impaired in

Fungal inhibition in four commonly used agar media was improved by substituting natamycin (pimaricin) for cycloheximide. The recovery of bacteria was not affected by natamycin, whereas fungal contamination from a variety of samples was significantly suppressed. Furthermore, natamycin lacks the

Control of polyene macrolide production in Streptomyces natalensis is mediated by the transcriptional activator PimR. This regulator combines an N-terminal domain corresponding to the Streptomyces antibiotic regulatory protein (SARP) family of transcriptional activators with a C-terminal half homologous to guanylate
