A series of beta-benzylaspartate derivatives were prepared from N-trityl-L-aspartate dimethyl ester and evaluated as inhibitors of neuronal glutamate transporter EAAT3. The result of the structure-activity studies suggests that the position occupied by the aromatic ring of beta-benzylaspartate within the binding site of EAAT3 may be different from that occupied by comparable groups in previously identified inhibitors, such as L-threo-benzyloxy aspartate (TBOA). Further, halogen substitutions at the 3-postition of the aromatic ring of beta-benzylaspartate can increase the potency with which the analogues inhibit EAAT3. (C) 2008 Elsevier Ltd.

[EN] The present invention provides an L-aspartate derivative compound represented by the following structure (I) wherein Ar represents an aromatic group; L represents a linking moiety; R represents hydrogen, alkyl, aryl, or heteroaryl; and ~~~ indicates that the stereochemistry at the 3-position can be R or S. The compounds of the invention are useful for selectively inhibiting EAAT3 and for enhancing synaptic transmission. Additionally, the inventive compounds can be used to treat a patient suffering from Alzheimers disease or a neuropathy or a neurodegenerative disease in which L-glutamate transporter activity is involved in the onset of the disease. [FR] L'invention concerne un composé dérivé de L-aspartate, représenté par la formule suivante: (I), dans laquelle Ar représente un groupe aromatique; L représente un groupe caractéristique de liaison; R représente hydrogène, alkyle, aryle ou hétéroaryle; et ~~~ indique que la stéréochimie en position 3 peut être R ou S. Les composés selon l'invention sont utiles dans l'inhibition sélective de EAAT3 et dans le renforcement de la transmission synaptique. Lesdits composés peuvent également être utilisés pour traiter un patient souffrant de la maladie d'Alzheimer, d'une neuropathie ou d'une maladie neurodégénérative dans laquelle l'activité des transporteurs de L-glutamate est impliquée dans l'apparition de la maladie.
