Effect of the Tc-Nitrido group on the behaviour of 99mTc-radiopharmaceuticals
The preparation of the 99mTcN-complexes of gluconate, EHDP, HIDA and PIPIDA by substitution reactions of 99mTcNCl4− is described. Studies of the distribution of these complexes in mice indicate that the presence of the Tc-nitrido group significantly alters the biological properties of the 99mTc-complexes formed using these ligands. Results suggest that the 99mTcN-complexes of these ligands are labile and undergo some ligand exchange in vivo.
