Galangin as a direct inhibitor of vWbp protects mice from Staphylococcus aureus-induced pneumonia.

ABSTRACT: The surge in multidrug resistance in Staphylococcus aureus (S. aureus) and the lag in antibiotic discovery necessitate the development of new anti-infective strategies to reduce S. aureus infections. In S. aureus, von Willebrand factor-binding protein (vWbp) is not only the main coagulase that triggers host prothrombin activation and formation of fibrin cables but also bridges the bacterial cell wall and von Willebrand factor, thereby allowing S. aureus to bind to platelets and endothelial cells, playing a vital role in pathogenesis of S. aureus infections. Here, we have identified that galangin, a bioactive compound found in honey and Alpinia officinarum Hance, is a potent and direct inhibitor of vWbp by coagulation activity inhibition assay, thermal shift assay and biolayer interferometr
