Low temperature and late-stage radiolabeling of peptides with fluorine-18 enabled by electron-deficient pyridine tag. Transposition to an automated “on-resin” radiolabeling.
The present invention relates to new and improved methods of synthesizing radiolabelling agents which can be used to label biomolecules for use as radiopharmaceuticals. It further relates to certain novel radiolabelling agents and their use in such methods. PET imaging methods and methods of diagnosis employing such radiolabelling agents form a further aspect of the invention.
The present technology is directed to compounds, intermediates thereof, compositions thereof, medicaments thereof, and methods related to the imaging of mammalian tissue overexpressing PSMA. The compounds are of Formula I
or a pharmaceutically acceptable salt thereof, wherein one of R
1
, R
2
, and R
3
is
and of Formula IV
or a pharmaceutically acceptable salt thereof.
