Abstract: In this paper, some new BAT derivatives are designed and synthesized in order to find some ideal myocardial imaging agents. These ligands form penta-coordinated complexes with indium cation. The structures of ligand BAT-TE and complexes In-BAT-TE and In-BAT-ETE are determined by X-ray crystallography at first. Biodistribution shows that the higher lipophilicity of complex induces apparently higher myocardial accumulation. Up to date, complex B is the best 113mIn-labeled myocardial imaging agent. It is also suited to 111In.
