New hydroxybenzyl and hydroxypyridylmethyl substituted triazacyclononane ligands for use with gallium(III) and indium(III)

The 67Ga(III) and/or 111In(III) complexes of four new hexadentate ligands have been prepared and evaluated in vitro and in vivo. These substituted triazacyclononane ligands bind the metal ion through three tertiary ring nitrogens and three oxygens from pendant phenolic or hydroxypyridyl arms. The hy...
