(±)-H3RESCA-TFP

(±)-H3RESCA-TFP ((±)-H3L28) is a tetrafluorophenyl ester derivative of restrained complexing agent (RESCA). (±)-H3RESCA-TFP can be used to conjugate the chelator with a biomolecule via amine coupling (e.g., N terminus and/or the ε-amino groups of lysine)[1].

The aluminum fluoride restrained complexing agent (Al18F-RESCA) method combines the chemical advantages of a chelator-based radiolabeling method with the unique physical properties of the radionuclide of choice, fluorine-18. Proteins of interest can be conjugated to RESCA via amine coupling using (±)-H3RESCA-TFP. Al18F-labeled proteins can be obtained with moderate (12-17 GBq/µmol) to good (80-85 GBq/µmol) apparent molar activity, depending on the starting activity of 18F-[1].
