Wortmannin ≥98% (durch TLC)
Lieferant: ENZO LIFE SCIENCES AG
PI3 kinase inhibitor
Potent and selective inhibitor of phosphatidyl-inositol 3-kinase. Active in purified preparations and cytosolic fractions(IC50 = 5nM) and is highly cell permeable. Inhibits fMLP induced PIP3 and superoxide anion production (IC50 = 50nM) in guinea pig neutrophils and blocks the metabolic effects of insulin in isolated rat adipocytes without affecting the insulin receptor tyrosine kinase activity. Covalently binds to PI 3-kinase and is selective, inhibiting other kinases such as PI 4-kinase and myosin light chain kinase at concentrations 100-fold higher than that required for inhibition of PI 3-kinase. The half-life of wortmannin in culture media is quite short (8-13 minutes), care should be taken to account for this decomposition when planning experiments. Markedly potentiates the LPS-induced nitric oxide (NO) production from macrophages. Induces in vivo Alzheimer-like hyperphosphorylation in tau.
