  Synthesis and Preclinical Evaluation of Bifunctional Ligands for Improved Chelation Chemistry of ⁹⁰Y and ¹⁷⁷Lu for Targeted Radioimmunotherapy

  摘要：

  We report a practical and high-yield synthesis of a bimodal bifunctional ligand 3p-C-NETA-NCS containing the isothiocyanate group for conjugation to a tumor targeting antibody. 3p-C-NETA-NCS was conjugated to a tumor-targeting antibody, trastuzumab, and the corresponding 3p-C-NETA-trastuzumab conjugate was evaluated and compared to trastuzumab conjugates of the known bifunctional ligands C-DOTA, C-DTPA, and 3p-C-DEPA for radiolabeling kinetics with Y-90 and Lu-177. 3p-C-NETA-trastuzumab conjugate exhibited extremely rapid complexation kinetics with Y-90 and Lu-177. Y-90-3p-C-NETA-trastuzumab and Lu-177-3p-C-NETA-trastuzumab conjugates were stable in human serum for 2 weeks. A pilot biodistribution study was conducted to evaluate in vivo stability and tumor targeting of Lu-177-radiolabeled trastuzumab conjugate using nude mice bearing ZR-75-1 human breast cancer. Lu-177-3p-C-NETA-trastuzumab conjugate displayed low radioactivity level at blood (1.6%), low organ uptake (<2.2%), and high tumor-to-blood ratio (6.4) at 120 h. 3p-C-NETA possesses favorable in vitro and in vivo profiles and is an excellent bifunctional chelator that can be used for targeted RIT applications using Y-90 and Lu-177 and has the potential to replace DOTA and DTPA analogues in current clinical use.

  A new bifunctional ligand 3p-C-DEPA was synthesized and evaluated for use in targeted alpha-radioimmunotherapy. 3p-C-DEPA was efficiently prepared via regiospecific ring opening of an aziridinium ion and conjugated with trastuzumab. The 3p-C-DEPA-trastuzumab conjugate was extremely rapid in binding Bi-205/6, and the corresponding Bi-205/6-3p-C-DEPA-trastuzumab complex was stable in human serum. Biodistribution studies were performed to evaluate in vivo stability and tumor targeting of Bi-205/6-3p-C-DEPA-trastuzumab conjugate in tumor bearing athymic mice. Bi-205/6-3p-C-DEPA-trastuzumab conjugate displayed excellent in vivo stability and targeting as evidenced by low organ uptake and high tumor uptake. The results of the in vitro and in vivo studies indicate that 3p-C-DEPA is a promising chelator for radioimmunotherapy of Bi-212 and Bi-213.
