Radiometallated receptor-avid peptide conjugates for specific in vivo targeting of cancer cells

Nucl Med Biol. 2001 Jul;28(5):527-39. doi: 10.1016/s0969-8051(01)00209-8.

Abstract

New receptor-avid radiotracers are being developed for site-specific in vivo targeting of a myriad of receptors expressed on cancer cells. This review exemplifies strategies being used to design radiometallated peptide conjugates that maximize uptake in tumors and optimize their in vivo pharmacokinetic properties. Efforts to produce synthetic peptide analogues that target the following three receptor systems are highlighted: Gastrin releasing peptide (GRP), alpha-melanocyte stimulating hormone (alpha-MSH), and guanylate cyclase-C (GC-C) receptors.
