Abstract

Abstract Aiming to develop new strategies for the labeling of hydroxyl-containing biomolecules with the organometallic core fac-[99m Tc (CO) 3]+, we have prepared a new model bifunctional chelator, L4 (ethyl hydrogen (2-{[2-(3, 5-dimethyl-1H-pyrazol-1-yl) ethyl] amino} ethyl) phosphonate), combining a pyrazolyl-amine chelating group and a monophosphonate ethyl ester function (–P (O) OHOEt). The phosphonate group allows ...
