体外研究：

The inhibition of MLCK by Wortmannin is not affected by calmodulin or peptide substrat, while reduced by high concentration of ATP. Wortmannin directly interacts with the catalytic domain of MLCK and leads to an irreversible loss of the enzyme activity. Wortmannin has no inhibitory to cAMP-dependent protein kinase, cGMP-dependent protein kinase, and calmodulin-dependent protein kinase II, and has little effect on protein kinase C activity. Wortmannin inhibits N-formylmethionyl-leucylphenylalanine (fMLP)-stimulated PtdInsP3 (phosphatidylinositol 3,4,5-trisphosphate) formation with IC50 of 5 nM and this inhibition is completely abolished when pretreated with 100 nM Wortmannin in human neutrophils, with increased PtdInsP2 levels and no effects on cellular PtdInsP and PtdIns contents. Wortmannin could develop oscillatory changes in F-actin content and does not inhibit fMLP-stimulated actin polymerization in neutrophils. Wortmannin irreversibly inhibits phosphatidylinositol 3-kinase (PI3-kinase) activity with binding to the 110-kDa protein (IC50 of 3 nM) and has no effect PI4-kinase in RBL-2H3 cells. Wortmannin also inhibits both Fc epsilon RI-mediated histamine secretion and leukotriene release, with no effect on the activation of the tyrosine kinase Lyn. Wortmannin completely abolishes the insulin-induced hexose uptake in isolated rat adipocytes at 0.1 μM, without impairing isoproterenol-stimulated lipolytic activity. Wortmannin suppresses insulin-induced production of nitric oxide by 50% at 500 nM in human umbilical vein endothelial cells, which is in response to IGF-1. Wortmannin suppresses DNA double strand break (DSB) repair and has no effect on DSB levels or the kinetics of single strand break (SSB) repair in Chinese hamster ovary cells at 50 μM. Wortmannin could potentiate ionizing radiation (IR)-induced cytotoxicity with no toxicity by itself. Wortmannin inhibits polo-like kinase (PLK1) activity IC50 of 24 nM in intact G2/M-arrested cells. Wortmannin increases Toll-like receptor (TLR)-mediated accumulation of IL-6 in human macrophages with EC50 of 50 nM. Meanwhile Wortmannin significantly enhances TLR-mediated inducible nitric-oxide synthase (iNOS) expression and nitrite accumulation in mouse macrphages. Wortmannin activates the nuclear factor-κB and up-regulates the cytokine mRNA production. Wortmannin also inhibits Polo-like kinase (PlK) 1 and PlK3, which play important roles in mitosis. Wortmannin treatment could lead to a reduction in phosphorylation of p53 on serine 20 induced by DNA damage. Wortmannin suppresses hyaluronan-induced Akt phosphorylation and cell motility/migration in SW1990 cells.

体内研究：Wortmannin inhibits peritoneal metastasis of SW1990 in mice at 1 mg/kg, without any weight loss. Wortmannin inhibits phosphatidylinositide 3-kinase-protein kinase B (PKB)/Akt phosphorylation in both normal tissues (lung, heart and brain homogenates) and tumor tissue in mice, without mortality or acute toxicity at 0.7 mg/kg. Combination with LY188011, Wortmannin significantly increases apoptosis and inhibit tumor growth in orthotopic tumor, while both monotherapy could not.
