Background:
Cyclo(RGDyK) is a cyclic peptide ligand of αVβ3 integrin (IC50= 37.5 nM) that contains the αVβ3 integrin-binding sequence arginine-glycine-aspartate (RGD).1It has been conjugated to radiolabels or fluorescent probes for the visualization of αVβ3-mediated neoangiogenesis or optical imaging of αVβ3-expressing tumors in live mice.2,1Cyclo(RGDyK) has also been conjugated to the DNA topoisomerase I inhibitor SN38 and an SN38-releasing trigger moiety to form a prodrug that targets cells overexpressing αVβ3 integrin and induces cytotoxicity in KB human cervical carcinoma cells.3
