Razuprotafib
Razuprotafib is a small molecule inhibitor of vascular endothelial protein tyrosine phosphatase (VE-PTP), with potential vasculature stabilizing activity. Upon administration, razuprotafib targets, binds to and inhibits VE-PTP, which is a negative regulator of the endothelial cell (EC)-specific receptor tyrosine kinase (RTK) Tie2. This restores Tie2 activation, which may improve endothelial function and stabilize blood vessels. VE-PTP is upregulated in stressed endothelium associated with a variety of diseases. Tie2 plays an important role in endothelial function and vascular stability. A decrease in Tie2 activation leads to vascular leakage and inflammation.
