conformation and that this cyclization chemistry modulated the geometry of macrocycles of different residue lengths. In vitro studies showed that cPRGDA and cPRGDAA both selectively bound to αVβ3-overexpressing U87 glioblastoma cells, and that cPRGDA had a better bindingaffinity compared to cPRGDAA. The improvedbindingaffinity of cPRGDA was attributed to the fixed Pro-Cα-Asp-Cα distance surrounding
