Description_x000D_ Application_x000D_ Cilengitide trifluoroacetic acid salt has been used as an inhibitor of integrin αvβ5._x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ Cilengitide is a vascular targeting agent (VTA) that acts as an integrin antagonist. Cilengitide is a cyclized Arg-Gly-Glu(RGD)-containing pentapeptide that selectively blocks activation of the αvβ3 and αvβ5 integrins._x000D_ It exhibits antitumor activity in glioblastoma multiforme tumors. Integrins are heterodimers of α and β chain. They are transmembrane receptors which are responsible for cell-to-cell and cell-extracellular matrix interactions. They control tumor angiogenesis, invasion and migration.
