(3-Alkoxyisoxazol-4-yl)-substituted 2-amino carboxylic acid derivatives and sulfur analogues thereof having general formula (I) or (II),
wherein R1 is hydrogen, alkyl, alkenyl, alkynyl, cycloalk(en)yl, cycloalk(en)yl-alk(en/yn)yl or optionally substituted phenyl-alk(en/yn)yl; A is a bond or a hydrocarbon spacer group; B is a group —CRa(NRbRc)—COOR5 wherein Ra-Rc are independently hydrogen or alkyl, and R5 is defined as R1 or pivaloyloxymethyl, or B is a group of Formula (III),
wherein R2, R3 and R4 are independently selected from hydrogen, a non-aromatic hydrocarbon group, phenyl- and thienyl-alkyl, and a hetero aliphatic group, or R3 and R4 are connected, thereby forming an alkylene, alkenylene or alkynylene group, or R4 and R2 are connected in order to form an alkylene, alkenylene or alkynylene group, optionally substituted with hydroxy or methyl, or to form CH2—O—CH2; E is COOR6, where R6 is defined as R5, or E is a tetrazolyl or triazolyl; X is O or S; and Y is O or S; are excitatory amino acid (EAA), in particular AMPA and/or NMDA receptor ligands, useful in the treatment of cerebral ischaemia, Huntington's disease, epileptic disorders, Parkinson's disease, Alzheimer's disease, schizophrenia, pain, depression and anxiety.
