IONOMYCIN Chemical Properties,Usage,Production

Description

Ionomycin (56092-81-0) is a highly selective nonfluorescent calcium (Ca2+) ionophore.1 Induces a rapid rise in cytosolic Ca2+ in human neutrophils which is due to both release from cytosolic Ca2+ stores as well as Ca2+ influx.2 It activates (2 μM) and primes (20-200 nM) neutrophil NADPH oxidase2. Down regulates beta-catenin/Tcf signaling in a colon cancer cell line via suppressing the binding of Tcf to its specific DNA-binding site.3 In rat hepatoma cells, sub-lethal ionomycin activates the stress response by activating SAPK/JNK and HSF/HSE interaction leading to upregulation of HSP70 biosynthesis.4

Chemical Properties

White powder

Uses

Ionomycin was isolated from Streptomyces conglobatus as a potent Gram positive antibiotic . During isolation, it was recognised that ionomycin exhibits a very high affinity and selectivity for calcium ions, suggesting the metabolite acts as a calcium ionophore. More recently, ionomycin has been used in cell biology as a universal calcium ionophore to explore the role of calcium regulation in the cell.

Uses

Ionomycin is more effective than A23187 as a Ca++ionophore. Ionomycin is used in research on Ca++ transport across biological membranes; Ionomycin induces apoptotic degeneration of embryonic cortical neurons

Uses

Ionomycin free acid is a beneficial tool in research to raise intracellular calcium levels. Also this antibiotic can be used to study the calcium transport across the plasma membrane. It has been shown to induce central demyelination , inhibit adrenal bovine TREK-1 channels , and to regulate cell division of mature human B cells . It is used to study the effects of calcium flux on endoplasmic reticulum (ER) stress, mitochondrial stress and intrinsic apoptosis mechanisms. It is also used to stimulate the intracellular production of the cytokines, interferon, perforin, IL-2, and IL-4 usually in conjunction with PMA.

Definition

ChEBI: 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 osition 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 memb anes.

General Description

Highly specific for divalent cations (Ca²⁺ > Mg²⁺ >> Sr²⁺ = Ba²⁺). More effective than antibiotic A23187 as a mobile ion carrier for Ca²⁺. Complexes with Ca²⁺ between pH 7 and 9.5, causing significant absorption in the UV range; however, in contrast to A23187 (Cat. No. 100105), it is not fluorescent. Useful for studies of Ca²⁺ transport across biological membranes and measurement of cytoplasmic free Ca²⁺. Induces apoptotic neuronal degeneration in embryonic cortical neurons. Also induces cell cycle arrest in the G₁ interval of mature Burkitt lymphoma cell lines.

Biological Activity

Calcium ionophore; more specific than A23187 (5-(Methylamino)-2-[[2R,3R,6S,8S,9R,11R)-3,9,11-trimethyl-8-[(1S)-1-methyl-2-oxo-2-(1H-pyrrol-2-yl)-ethyl]-1,7-dioxaspiro[5.5]undec-2-yl]methyl]-4-benzoxazolecarboxylic acid ).

Biochem/physiol Actions

Cell permeable: yes

in vitro

calcium ion can be extracted by ionomycin fom the queous phase into the organic phase. ionomycin also acts as a mobile ion carrier, which transports the cation across a solvent barrier [1].

in vivo

efficiency of ionomycin on oocyte activation and subsequent development was evaluated, which identified ionomycin as an efficient activator at the concentation of 10 μmol/l. with a second exposure to 5 μmol/l ionomycin on blastocyst development, an improved effect was found. no adverse effects of ionomycin on mouse embryo development were identified [2].

storage

-20°C
