(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.
具有通式(I)或(II)的[(3-烷氧基异噁唑-4-基)-取代基] 2-氨基羧酸衍生物和硫化物类似物,其中R1为氢,烷基,烯基,炔基,环烷(烯)基,环烷(烯)基-烷(炔)基或可选取代的苯基-烯(炔)基; A为键或烃基间隔基; B为CRa(NRbRc)-COOR5基团,其中Ra-Rc独立地为氢或烷基,R5定义为R1或异丙氧甲基,或B为式(III)中的基团,其中R2,R3和R4独立地选自氢,非芳香烃基,苯基和噻吩基-烷基,以及异构脂肪基,或R3和R4连接,从而形成一个烷基,烯基或炔基,或R4和R2连接以形成一个烷基,烯基或炔基,可选地用羟基或甲基取代,或形成CH2-O-CH2; E为COOR6,其中R6定义为R5,或E为四唑基或三唑基; X为O或S; Y为O或S; 是兴奋性氨基酸(EAA),特别是AMPA和/或NMDA受体配体,在治疗脑缺血,亨廷顿病,癫痫障碍,帕金森病,阿尔茨海默病,精神分裂症,疼痛,抑郁和焦虑方面有用。
