Application

Cilengitide trifluoroacetic acid salt has been used as an inhibitor of integrin αvβ5.

Biochem/physiol Actions

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.
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.

Glioblastoma multiforme (GBM), a highly invasive and vascular cancer, responds poorly to conventional cytotoxic therapy. Integrins, widely expressed in GBM and tumor vasculature, mediate cell survival, migration and angiogenesis. Cilengitide is a potent alphavbeta3 and alphavbeta5 integrin inhibitor. To summarize
