Cenupatide
Based on 1 Customer Validation
Cenupatide (UPARANT) is a uPAR and FPR antagonist with anti-angiogenic, anti-inflammatory, and vascular barrier regulatory activities, as well as high stability and resistance to enzymatic degradation in blood/plasma. Cenupatide blocks the uPAR-FPR interaction, reduces VEGF-induced phosphorylation levels of AKT, VEGFR-2, STAT3, JNK, p38 MAPK, ERK1/2, and NF-κB p65, and inhibits αvβ3 integrin activation. Cenupatide suppresses endothelial cell migration, invasion, tube formation, and angiogenic signaling pathways, restores tight junctions and blood-retinal barrier integrity, reduces pro-inflammatory marker levels, and inhibits apoptosis. Cenupatide reduces retinal neovascularization, renal fibrosis, and vascular leakage, and restores visual function in preclinical models. Cenupatide is applicable to research related to retinopathy, diabetic complications, ocular diseases, cancer, and inflammatory diseases.
