Arginine–glycine–aspartic acid (RGD)-containing peptides have been traditionally used as PET probes to noninvasively image angiogenesis, but recently, small selective molecules for α₅β₁ integrin receptor have been developed with promising results. Sixty-one antagonists were screened, and tert-butyl...

The development of RGD-based antagonist of αvβ3 integrin receptor has enhanced the interest in PET probes to image this receptor for the early detection of cancer, to monitor the disease progression and the response to therapy. In this work, a novel prosthetic group (N-(4-fluorophenyl)pent-4-ynamide or FPPA) for the 18F-labeling of an αvβ3 selective RGD-peptide was successfully prepared....
