  • .beta.-hydroxyaspartic acid derivatives
    Patent number: 6147113
    Abstract: The present invention provides blockers for glutamate transporters. During a series of syntheses searching for glutamate uptake inhibition in Xenopus oocytes injected with bovine glutamate transporter genes (BGLAST), we obtained .beta.-hydroxyaspartic acid derivatives of the following chemical formula (1): ##STR1## wherein R represents an aromatic acyl group which may be substituted on the ring, a straight or branched lower aliphatic acyl group, an aryl group which may be substituted on the ring, an aralkyl group which may be substituted on the ring, or a straight or branched lower alkyl group; and salts thereof. These compounds are blockers of glutamate transporters, which are useful for the understanding of the function of glutamate transporters and show promise for the treatment of various neurodegenerative diseases.
