Monoclonal antibodies have been widely exploited for both diagnostic and therapeutic purposes. For antibody radiolabeling with Cu-64, requirement of a bifunctional chelator which can hold the radio metal robustly is essential. Thus development of ultrastable chelator is needed. However, most heat-sensitive antibodies cannot be radiolabeled utilizing these chelators because of their high temperature radiolabeling profile. It thus limits its wide applications. Herein we develop a new type of versatile cross-bridged macrocyclic chelator (PCB-TE2A-alkyne), which can be transformed to any functional group prior to radiolabeling for easy conjugation with antibody. Modifications to different functionality did not require any tedious purification and after radiolabeling it can be conjugated to antibody in excellent yield. It thus facilitates a general and broad platform for antibody radiolabeling with Cu-64. The applicability was demonstrated using trastuzumab in NIH3T6.7 tumor-bearing BALB/c nude mice.
