摘要
A series of Tc-99m-DADT complexes substituted with heterocyclic amines were synthesized and tested for their ability to cross the BBB. Each Tc-99m-DADT complex analysed by HPLC was found to consist of two epimers. The more lipophilic epimers were biodistributed in mice. The data demonstrated a significant brain uptake (3-12% dose/g whole brain) and a high lung accumulation (11-85% dose/g) at 2 min p.i. Between the partition coefficients of the technetium complexes, a linear correlation for lung accumulation was observed, while a parabolic curve for brain uptake was found.
