Ligands for molecular imaging: the synthesis of bis(thiosemicarbazone) ligands.
Bis(thiosemicarbazones) have been of interest to chemists for over fifty years; they display antitumour, antibiotic and antiviral properties. Recently it has become apparent that they may also provide a convenient way of labelling biologically active molecules by using metallic radionuclides and/or fluorescence. Although apparently simple, the synthesis of bis(thiosemicarbazone) ligands can be problematic. This article provides a summary of the published literature, based on the synthetic strategies used and indicates some of the difficulties that may arise.
