Abstract: Described herein are Tz/TCO-based pretargeting strategies using an Al[18F]-NOTA-labeled tetrazine radioligand. This imaging strategy enables delineation of cancer at earlier time points compared to other imaging strategies and further decreases the radiation dose to healthy tissues compared to directly labeled antibodies. Al-based 18F imaging of small molecules, such as tetrazine, has not been previously achieved due to the decomposition of tetrazine during radiofluorination. Radiofluorination is advantageous over other radiolabeling methods because, in addition to having a shorter half-life, 18F is more readily available to produce and therefore integrated into hospital workflows.

Abstract: A label that permits rebridging of disulfide linkages in antibodies or proteins. The label has a general formula given by wherein R1 is methyl, ethyl or propyl and R2 is a metal chelator, a fluorophore or a click-chemistry synthon.

Abstract: Peptide formulations of a general formula of X-mtp53ODP, where mtp53ODP is a peptide that binds to tetrameric mp53 tetramers in vivo. X is a detection agent, such a fluorophore or radioligand, and/or a DNA-damaging agent. The primary structures of suitable mtp53ODPs are given as SEQ ID NOS: 1-8.
