Vinylsulfone-based 18f-labeling compositions and methods and uses thereof

摘要

A thio-selective radioactive labeling agent has the following general formula: *R-L-VS, wherein said *R is a radioisotope, L is a linking group, and VS is a vinylsulfone functional group, wherein said labeling agent is capable of covalently bonding to thiol containing biomolecules such as proteins or peptides. Use of said labeling agents for labeling neurotensin and its variants are also disclosed.
