생화학적/생리학적 작용

Nigericin is a polyether ionophore which catalyzes the electroneutral exchange of alkali metal (K+) for H+ (antiport). Nigericin transports monovalent cations across membranes with the following specificity: K+ >Rb+ >Cs+ >>Na+ and thus, disrupts membrane potential and stimulates ATPase activity in mitochondria.
Nigericin kills bacteria by facilitating the diffusion of ions across membranes.
Low concentration (0.5 μM) of Nigericin rapidly decreases pHi, causing stimulation of PG production 1.5- to 2-fold in cerebral microvascular endothelial cells and arresting of DNA synthesis in Erlich acites carcinoma cells. Treatment of Hela cells, after entry of poliovirus, with nigericin, prevents the inhibition of host protein synthesis by poliovirus. Nigericin is also widely used in studies of the consequences of changes in membrane potential in variable systems.

제조 메모

Nigericin sodium salt ready made solution is provided at 6.7 mM concentration. The solution can be further diluted with a desired solvent to a working concentration (0.5-10 μM).

The mode of action of reutericyclin was determined with fluorescent dyes that probed the permeability of the cytoplasmic membrane by large molecules, protons, and potassium. A comparison of reutericyclin activity with those of nisin, nigericin, and valinomycin demonstrated that reutericyclin

Acidification of the cytoplasm of Ehrlich ascites carcinoma cells to pH 6.3 arrests DNA synthesis in these cells. Such an effect can be achieved by incubating the cells at pH 6.2 or by adding low concentrations of the K+/H+ antiporter

Valinomycin, nigericin and trichlorocarbanilide were assessed for their ability to control the protonmotive force in Escherichia coli cells. Valinomycin, at high K+ concentrations, was found to decrease the membrane potential delta phi and indirectly to decrease the pH gradient delta
