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.

4 Pharmacology and Biochemistry

4.1 Mechanism of Action

Razuprotafib inhibits [VE-PTP](https://go.drugbank.com/bio_entities/BE0003769) (a negative regulator of Tie2 in diseased blood vessels) by binding and inhibiting the intracellular catalytic domain of VE-PTP that inactivates Tie2. This in turn allows razuprotafib to restore Tie2 activation to allow for enhancement of endothelial function and stabilization of blood vessels. Razuprotafib is being investigated against diabetic vascular complications and acute respiratory distress syndrome (ARDS) in COVID-19.
