Wortmannin is the first described PI3K inhibitor with IC50 of 3 nM, with little selectivity within the PI3K family. Also blocks autophagosome formation and potently inhibits DNA-PK/ATM with IC50 of 16 nM and 150 nM.
A fungal metabolite which inhibits Pl3-kinase
A cell-permeable fungal metabolite that acts as a potent, selective and irreversible inhibitor of phosphatidylinositol 3-kinase in purified preparations and cytosolic fractions (IC50=5 nM). Blocks the catalytic activity of PI 3-kinase without affecting upstream signaling events. Preincubation of fibroblasts with wortmannin abolishes PDGF-mediated Ins(3,4,5)P3 formation (IC50=5 nM). Blocks the metabolic effects of insulin in isolated rat adipocytes without affecting insulin receptor tyrosine kinase activity. Inhibits platelet-activating factor-induced MAP kinase activation in guinea pig neutrophils (200-300 nM). Also inhibits other kinases such as myosin light chain kinase (IC50=200 nM) and PI 4-kinase at concentrations higher than those required for inhibition of PI 3-kinase. Also blocks phospholipase D.
