The synthetic bis(zinc(II)-dipicolylamine) (DPAZn2) coordination complexes are known to have a high specific and selective affinity to target the exposed phosphatidylserine (PS) on the surface of dead and dying cells. An (18)F-labeled DPAZn2 complex (4-(18)F-Fluoro-benzoyl-bis(zinc(II)-dipicolylamine), (18)F-FB-DPAZn2) as positron emission tomography (PET) tracer was developed and evaluated for in vivo imaging of tumor treated with a chemical agent. The in vitro cell stain studies revealed that fluorescent DPAZn2 complexes (Dansyl-DPAZn2) stained the same cells (apoptotic and necrotic cells) as fluorescein isothiocyanate (FITC) labeled Annexin V (FITC-Annexin V). The radiosynthesis of (18)F-FB-DPAZn2 was achieved through the amidation the precursor bis(2,2'-dipicolylamine) derivative (DPA2) with the prosthetic group N-succinimidyl-4-[(18)F]-fluorobenzoate ((18)F-SFB) and chelation with zinc nitrate. In the biodistribution study, the fast clearance of (18)F-FB-DPAZn2 from blood and kidney was observed and high uptake in liver and intestine within 90 min postinjection was also found. For the PET imaging, significantly higher tumor uptake of (18)F-FB-DPAZn2 was observed in the adriamycin (ADM)-treated Hepa1-6 hepatocellular carcinoma-bearing mice than that in the untreated tumor-model mice, while a slightly decreased tumor uptake of (18)F-FDG was found in the ADM-treated tumor-bearing mice. The results indicate that (18)F-FB-DPAZn2 has the similar capability of apoptosis detection as FITC-Annexin V and seems to be a potential PET tracer for noninvasive evaluation and monitoring of anti-tumor chemotherapy. The high uptake of (18)F-FB-DPAZn2 in the abdomen needs to optimize the structure for improving its pharmacokinetics characteristics in the future work.
