Several bifunctional chelates (BFCs) were investigated as carriers of (64)Cu for PET imaging. The most widely used chelator for (64)Cu labeling of BFCs is DOTA (1,4,7,10-tetraazacyclododecane-N,N',N″,N'''-tretraacetic acid), even though this complex exhibits only moderate in vivo stability. In this study, we prepared a series of alternative chelator-peptide conjugates labeled with (64)Cu, measured in vitro receptor binding affinities in human breast cancer T47D cells expressing the gastrin… CONTINUE READING
