  Rational Design and Generation of a Bimodal Bifunctional Ligand for Antibody-Targeted Radiation Cancer Therapy

  摘要：

  An antibody-targeted radiation therapy (radioimmunotherapy, RIT) employs a bifunctional ligand that can effectively hold a cytotoxic metal with clinically acceptable complexation kinetics and stability while being attached to a tumor-specific antibody. Clinical exploration of the therapeutic potential of RIT has been challenged by the absence of adequate ligand, a critical component for enhancing the efficacy of the cancer therapy. To address this deficiency, the bifunctional ligand C-NETA in a unique structural class possessing both a macrocyclic cavity and a flexible acyclic moiety was designed. The practical, reproducible, and readily scalable synthetic route to C-NETA was developed, and its potential as the chelator of Bi-212, Bi-213, and Lu-177 for RIT was evaluated in vitro and in vivo. C-NETA rapidly binds both Lu(III) and Bi(III), and the respective metal complexes remain extremely stable in serum for 14 days. Lu-177-C-NETA and Bi-205/6-C-NETA possess an excellent or acceptable in vivo biodistribution profile.

  The present application discloses compositions and methods of synthesis and use of F-18 labeled molecules of use, for example, in PET imaging techniques. The labeled molecules may be peptides or proteins, although other types of molecules may be labeled by the described methods. Preferably, the F-18 may be conjugated to a targeting molecule by formation of a metal complex and binding of the F-18-metal complex to a chelating moiety. Alternatively, the metal may first be conjugated to the chelating group and subsequently the F-18 bound to the metal. In other embodiments, the F-18 labeled moiety may comprise a targetable construct used in combination with a bispecific or multi specific antibody to target F-18 to a disease-associated antigen, such as a tumor-associated antigen. The F-18 labeled targetable construct peptides are stable in serum at 37° C. for a sufficient time to perform PET imaging analysis.
