Protein disulfide isomerase (PDI) is a ubiquitously expressed oxidoreductase required for proper protein folding. It is highly concentrated in the endoplasmic reticulum, but can also be released into the extracellular environment. Several in vivo thrombosis models have demonstrated that vascular PDI secreted by platelets and endothelial cells is essential for normal thrombus formation. Inhibition of extracellular PDI thus represents a potential strategy for antithrombotic therapy. Yet this approach requires the discovery of well-tolerated PDI inhibitors. A recent high throughput screen identified the commonly ingested flavonoid, quercetin-3-rutinoside, as an inhibitor of PDI. Quercetin-3-rutinoside blocked thrombus formation at concentrations that are commonly ingested as nutritional supplements. The observation that a compound with Generally Recognized As Safe status inhibits PDI and blocks thrombosis in animal models forms a rationale for clinical trials evaluating PDI inhibitors as a new class of antithrombotics.
