Razuprotafib (CAT: I008984) is indeed a small molecule inhibitor of vascular endothelial protein tyrosine phosphatase (VE-PTP). By targeting and inhibiting VE-PTP, razuprotafib prevents the dephosphorylation of the endothelial cell (EC)-specific receptor tyrosine kinase (RTK) Tie2. This inhibition leads to the restoration of Tie2 activation, which is crucial for maintaining endothelial function and vascular stability. Upregulation of VE-PTP is observed in stressed endothelium associated with various diseases. By restoring Tie2 activation, razuprotafib has the potential to improve endothelial function, stabilize blood vessels, and mitigate vascular leakage and inflammation. This makes razuprotafib a promising candidate for therapeutic interventions in conditions where endothelial dysfunction is implicated.
