Nigericin

Chemical compound

Nigericin is an antibiotic derived from Streptomyces hygroscopicus. Its isolation from soil from Nigeria was described in the 1950s, by R.L Harned, and in 1968 the structure could be elucidated by X-ray crystallography. The structure and properties of nigericin are similar to the antibiotic monensin. Commercially it is obtained as a byproduct, or contaminant, at the fermentation of geldanamycin. It is also called polyetherin A, azalomycin M, helixin C, antibiotic K178, and antibiotic X-464.
