The objective of this study was to develop a positron emission tomography (PET) probe with hypoxia targeting specificity and a relatively long half-life. The synthesis, Cu-64-labeling in vitro and in vivo study of the novel 2-nitroimidazole complex Cu-64-BMS2P2 is presented in this study. The hypoxia targeting capacity of Cu-64-BMS2P2 in vitro was evaluated and compared with the Cu-64-BMS181321, and confirmed by PET imaging in vivo and immunohistochemistry for carbonic anhydrase 9 (CA9) in a tumor mouse model. These results suggest that Cu-64-BMS2P2 is a promising candidate for PET hypoxia imaging and worthy of further investigations in dynamic hypoxia imaging. (C) 2016 Elsevier Ltd. All rights reserved.
