Designing new radiolabeled hypoxia-targeted drugs is of great help in the diagnosis of tumors. Hypoxia-targeted drugs with dual bioactive groups can enhance hypoxia selectivity, strengthen the binding of drugs to targets, and improve diagnostic accuracy compared with traditional hypoxia-targeted drugs containing only one nitroimidazole group. In this study, a series of novel radioiodine labeled tyrosine derivatives containing 2-nitroimidazole and benzenesulfonamide groups were synthesized and in vitro evaluated. In the uptake experiments of S180 cells that didn't express carbonic anhydrase IX (CAIX), the compound [
