摘要

A novel class of ligands, phenylenediamine-thiol-thioether (PhAT), was synthesized, and their-Tc complexes were evaluated for potential use as a functional brain imaging agent. The ligands reacted with Na-TcOd and SnCl2 to form single, stable, neutral, and lipophilic- Tc complexes. Several of these complexes showed significant brain uptake and retention in rats. In particular, the S-ethyl, allyl, and propargyl derivatives had high initial brain uptake ( ...
