BioAssay: AID 780744

Activation of alphaVbeta3 integrin in HUVEC at 10 uM by flow cytometry

The development of RGD-based antagonist of alphavbeta3 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 (18)F-labeling of an alphavbeta3 selective RGD-peptide was successfully more ..

Description:
Title: Synthesis and in vitro evaluation of a novel radioligand for alphavbeta3 integrin receptor imaging: [18F]FPPA-c(RGDfK).

Abstract: The development of RGD-based antagonist of alphavbeta3 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 (18)F-labeling of an alphavbeta3 selective RGD-peptide was successfully prepared. [(18)F]FPPA was obtained in three steps with a radiochemical yield of 44% (decay corrected). Conjugation to c(RGDfK(N3)) by the Cu(II) catalyzed Huisgen azido alkyne cycloaddition provided the [(18)F]FPPA-c(RGDfK) with a radiochemical yield of 29% (decay corrected), in an overall synthesis time of 140 min.
