| Hazard Information | Back Directory | [Description]
Dinactin is a macrotetrolide antibiotic that acts as an ionophore for monovalent cations, such as K+, NH4+, and Rb+. It is commonly used to study membrane properties. Dinactin is a component of a macrotetralide-rich antifungal mixture produced by Streptomyces. Dinactin inhibits T-cell proliferation and cytokine production in vitro and reduces pulmonary eosinophilia in antigen-challenged mice. | [Uses]
Dinactin is a hydrophobic cyclic ester that inhibits T-cell proliferation induced by IL-2. | [Uses]
Dinactin is a member of the macrotetrolide complex produced by a range of Streptomyces species. It is a monovalent cation ionophore with high selectivity for ammonium and potassium. Dinactin inhibits T-cell proliferation induced by IL-2 and cytokine production at nanomolar levels for IL-2, IL-4, IL-5 and interferon-γ. Dinactin has not previously been available for intensive investigation. | [in vitro]
dinactin inhibited t-cell proliferation induced by il-2, by mab to cd3, and by mabs to cd3 plus α-cd28 with identical dose-response curves. the ic50 was 10–20 ng/ml. dinactin inhibited cytokine production with ic50 values of 10 ng/ml for il-4 and il-5, 30 or 60 ng/ml for interferong or il-2, respectively [3].dinactin inhibited cytokine production through a post-transcriptional mechanism. dinactin also reduced pulmonary eosinophilia when administered within 1 d of airway antigen challenge [3]. | [References]
