Cilengitide is a cyclic Arg-Gly-Asp peptide with potential antineoplastic activity. Cilengitide binds to and inhibits the activities of the alpha(v)beta(3) and alpha(v)beta(5) integrins, thereby inhibiting endothelial cell-cell interactions, endothelial cell-matrix interactions, and angiogenesis.

How to use
Cilengitide is a cyclized RGD (Arg-Gly-Asp motif)-containing pentapeptide. Cilengitide blocks integrin ανβ3- and ανβ5-mediated endothelial cell attachment and migration. Cilengitide inhibits integrin-mediated binding to Vitronectin with IC50's of 0.4 and 0.4 μM in cell adhesion studies assessing the human melanoma M21 or UCLA-P3 human lung carcinoma cell lines . Cilengitide inhibits the attachment of human umbilical vein endothelial cells to Vitronectin with an IC50 of 2 μM .
Cilengitide (i.p. at 10, 50, and 250 μg three times per week) inhibits M21-L melanoma tumors growth in nude mice.
