The present invention concerns compounds of formula. In a preferable embodiment, X represents O; R1 represents C1-6alkyl; cycloC3-12alkyl or (cycloC3-12alkyl)C1-6alkyl, wherein one or more hydrogen atoms in a C1-6alkyl-moiety or in a cycloC3-12alkyl-moiety optionally may be replaced by C1-6alkyloxy, aryl, halo or thienyl; R2 represents hydrogen; halo; C1-6alkyl or amino; R3 and R4 each independently represent hydrogen or C1-6alkyl; or R2 and R3 may be taken together to form —R2-R3-, which represents a bivalent radical of formula -Z4-CH2-CH2-CH2- or -Z4-CH2-CH2- with Z4 being O or NR11 wherein R11 is C1-6alkyl; and wherein each bivalent radical is optionally substituted with C1-6alkyl; or R3 and R4 may be taken together to form a bivalent radical of formula —CH2-CH2-CH2-CH2-; R5 represents hydrogen; Y represents O; and aryl represents phenyl optionally substituted with halo. The invention also relates to the use of a compound according to the invention as a medicament and in the manufacture of a medicament for treating or preventing glutamate-induced diseases of the central nervous system, as well as formulations comprising such a compound and processes for preparing such a compound.
本发明涉及以下结构的化合物。在一个较好的实施方式中,X代表O;R1代表C1-6烷基;环C3-12烷基或(环C3-12烷基)C1-6烷基,其中C1-6烷基中的一个或多个氢原子或环C3-12烷基中的一个或多个氢原子可以选择性地被C1-6烷氧基,芳基,卤素或噻吩基所取代;R2代表氢;卤素;C1-6烷基或氨基;R3和R4各自独立地代表氢或C1-6烷基;或者R2和R3可以结合形成—R2-R3-,它表示一个式为-Z4-CH2-CH2-CH2-或-Z4-CH2-CH2-的二价基团,其中Z4为O或NR11,其中R11为C1-6烷基;并且每个二价基团可以选择性地被C1-6烷基取代;或者R3和R4可以结合形成一个式为—CH2-CH2-CH2-CH2-的二价基团;R5代表氢;Y代表O;芳基代表苯基,可以选择性地取代卤素。该发明还涉及根据该发明的化合物作为药物的用途以及用于治疗或预防中枢神经系统谷氨酸诱导疾病的药物的制造,以及包含这种化合物的配方和制备这种化合物的方法。
