Termination of glutamate receptor activation and maintenance of low extracellular glutamate concentrations are mainly achieved by glutamate transporters [excitatory amino acid transporters 1\u20135 (EAAT1\u20135)] located in nerve endings and surrounding glial cells. Selective and potent inhibitors have long been required to investigate the physiological significance of transporters in the regulation of synaptic transmission and the pathogenesis of neurological diseases. Non\u2010transportable blockers are desirable because, unlike competitive substrates, they do not cause ion flux and heteroexchange. After a series of possible candidate molecules, we synthesized\n                    <jats:italic>threo<\/jats:italic>\n                    \u2010\u03b2\u2010benzyloxyaspartate (TBOA), the first non\u2010transportable blocker for all subtypes of EAATs. In addition, TBOA analogs with a bulky substituent on their benzene ring showed enhanced inhibition of labeled glutamate uptake. Comparing the effects of substrates and non\u2010transportable blockers revealed the physiological roles of EAATs. We also developed a novel binding assay system using a tritium\u2010labeled TBOA analog. In this review, we describe the design and synthesis of these blockers and the functions of the EAATs elucidated with them. \u00a9 2008 The Japan Chemical Journal Forum and Wiley Periodicals, Inc.
