Cyclo(RGDfK) – Immunology – Antigens/Epitotes/Pools/Librairies

The cyclic pentapeptide cyclo(Arg-Gly-Asp-[D-Phe]-Lys) is a highly potent and selective inhibitor for the alphavβ3 integrin receptor. A related compound, cyclo(Arg-Gly-Asp-[D-Phe]-Val), is a promising anticancer drug candidate- it inhibits angiogenesis and induces apoptosis in vascular cells. Cyclic RGD-containing peptides are selective antagonists of integrins, proteins that play important roles in cell-cell and cell-matrix interactions. In a suitably labelled form, these peptides may serve as useful tools for diagnostic imaging and peptide targeted therapy of some types of cancer.
