What is Ionomycin?

Plain description, key identifiers and synonyms

Ionomycin is a very long-chain fatty acid that is docosa-10,16-dienoic acid which is substituted by methyl groups at positions 4, 6, 8, 12, 14, 18 and 20, by hydroxy groups at positions 11, 19 and 21, and by a (2',5-dimethyloctahydro-2,2'-bifuran-5-yl)ethanol group at position 21. An ionophore produced by Streptomyces conglobatus, it is used in research to raise the intracellular level of Ca2+ and as a research tool to understand Ca2+ transport across biological membranes. It has a role as a calcium ionophore and a metabolite. It is a polyunsaturated fatty acid, a very long-chain fatty acid, an enol and a cyclic ether.

Pharmacology

Ionomycin is a polyether antibiotic isolated from Streptomyces conglobatus sp. nov. Trejo with antineoplastic activity. Ionomycin is a calcium ionophore that increases intracellular Ca++ levels, possibly relating to endonuclease activation of lymphocytes and decreased ratio of Bcl-2 to Bax and ultimately apoptosis. In addition, this agent is used to investigate the role of intracellular calcium in cellular processes. (NCI)
