General description

A cell-permeable quinone reductase inhibitor with anti-coagulant properties. Binds competitively with NADH or NADPH to inhibit NAD(P)H:quinone oxidoreductase (NQO1). Shown to inhibit IGF-I-, menadione-, and DMNQ-mediated activation of stress-activated protein kinase/c-jun NH2-terminal kinase (SAPK/JNK) and subsequent phosphorylation of c-Jun, as well as stress-induced activation (hypertonic sorbitol) of SAPK/JNK. Does not affect p38 phosphorylation or protein kinase B (AKT) activation. Also shown to induce apoptosis in MCF7 breast carcinoma cells. Inhibits glutathione-S transferase (GST) A1-1 enzyme (Kiu = 4.4 µM, Kic = 3.6 µM) in vitro and in MCF7/VPα cells (a multidrug resistant derivative of MCF7 transfected with GST A1-1). Blocks brefeldin A-dependent mono-ADP-ribosylation in vitro and Golgi disassembly in living cells (IC50 = 180 µM and 150 µM, respectively).
A cell-permeable quinone reductase inhibitor with anticoagulant properties. Potentiates apoptosis by simultaneously blocking SAPK/JNK and NF-κB pathways. Does not affect phosphorylation of p38 or activation of AKT. Blocks brefeldin A-dependent mono-ADP-ribosylation in vitro and Golgi disassembly in living cells (IC50 = 180 µM and 150 µM, respectively).
