We have developed a radiolabeling strategy for synthetic polymers based on the formation of azo dye usable for both covalent and chelating labeling modalities under mild conditions. Poly[N-(2-hydroxypropyl)methacrylamide] and poly(N-isopropyl acrylamide) were used as model polymers. N-methacryloyl tyrosinamide was introduced into the polymers and the phenolic moiety was then reacted with diazotized chelator precursors. The conjugates were radiolabeled with both the covalently bound (iodine-125) and chelated (indium-111) radionuclides in high yields and sufficient in vitro stability of the labels was proven.
