General Description

Chemical structure: polyene Nystatin is a polyene macrolide antifungal, which is a polyketide produced by Streptomyces noursei ATCC 11455. This antibiotic contains a macrolactone ring, and its natural synthesis is initiated with acetyl CoA, which is followed by the condensation of three ethylmalonyl-CoA and 15 malonyl-CoA extender moieties.

Application

Nystatin has been used – for the treatment of human macrophage cell line U937, to study the effect of nystatin on the production of IL-8 (interleukin 8) by silver nanoparticle-treated U937 cell line to determine its effect on intracellular accumulation of OxLDL (oxidized low density lipoprotein) mediated by SR-BI (scavenger receptor class B type I) in COS-7 cell line as a lipid raft modulator on mice macrophages to study the relationship between increased number of lipid rafts and the heightened response of TNF-α (tumor necrosis factor) Nystatin is a polyene antibiotic. Its uses include preventing cell culture contamination and inducing interleukin (IL)-1, IL-8, and tumor necrosis factor α secretion in TLR2-expressing THP1 cells. This product is recommended for use in cell culture applications at 50 mg/L.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.Store under inert gas. Air and light sensitive. Keep in a dry place.

制霉菌素即用型溶液

一般描述

制霉菌素是一种抑制真菌和杀真菌的多烯抗生素。它与麦角甾醇结合，可增加敏感真菌的细胞膜通透性。制霉菌素主要对念珠菌属有临床活性。然而，据报道它对抗曲霉菌、球孢子菌、新型隐球菌、荚膜组织胞浆菌、芽孢杆菌和其他酵母和真菌也有效。制霉菌素也被用于通过酵母中的阴性选择来富集突变体。据报道，制霉菌素对酿酒酵母的最小抑制浓度（MIC）为 3μg/ml，而对于白色念珠菌的临床分离株，最小抑制浓度为 4-16μg/ml。

General Description

Nystatin is a fungistatic and fungicidal polyene antibiotic. It binds to ergosterol which increases cell membrane permeability in sensitive fungi. Nystatin is mainly clinically active against Candida species. However, it is also reported to be effective against Aspergillus, Coccidioides immitis, Cryptococcus neoformans, Histoplasma capsulatum, Blastomyces dermatidis, and other yeasts and fungi. Nystatin has also been used to enrich mutants by negative selection in yeasts. The minimum inhibitory concentration (MIC) of Nystatin to Saccharomyces cerevisiae was reported to be 3μg/ml while for clinical isolates of Candida albicans the MIC was reported to be 4-16μg/ml.
