Thermo Scientific Chemicals Nystatin, 85+%

General Description

• Nystatin is a polyene compound that shows anti-bacterial and antifungal activities against Streptomyces noursei, Streptomyces aureus, and other Streptomyces species

• It is also an ionophore with the capacity to increase membrane permeability

• Nystatin is a channel-forming ionophore and exerts its activity via formation of a membrane-spanning pore in the fungal plasma membrane, thus altering membrane permeability, allowing the leakage of intracellular contents, and the subsequent disruption of electrochemical gradients essential for proper cell function

Applications

• In in vitro experiments, Nystatin is an antifungal that is both fungistatic and fungicidal against a wide variety of yeasts and yeast-like fungi

• It has a higher selectivity for fungal cells over mammalian cells since nystatin presents greater binding affinity with ergosterol, a key sterol found in fungal cell walls, as opposed to its mammalian counterpart, cholesterol

• This compound is not active against organisms that do not contain sterols in their cell membrane (for example, bacteria)

• It is used on human macrophage cell line U937, to study its effect on the production of interleukin-8 by silver nanoparticle-treated U937 cell line

• It has the ability to prevent cell culture contamination as well as induce interleukin-1 and -8, and tumor necrosis factor α secretion in TLR2-expressing THP1 cells

• It modulates lipid raft profile in mice macrophages
