The invention is concerned with the use of sulfonamide derivatives of the general formula ##STR1## wherein R signifies lower-alkyl, phenyl, benzyl, naphthyl, pyridyl or thienyl, optionally substituted by one or more lower-alkyl, lower-alkoxy, lower-alkyl carbonyl-amino, halogen, cycloalkyl, nitro, amino, methylenedioxy, phenoxy or benzyloxy substituents, and the aromatic rings, can, in turn, be substituted by nitro, halogen or amino, R.sup.1 -R.sup.4 signify hydrogen, halogen, hydroxy, lower-alkyl, nitro, cyano, amino, lower-alkoxy, benzyloxy, trifluoromethyl or phenyl, optionally substituted by one or more lower-alkyl, trifluoromethyl, nitro, amino or hydroxy substituents, and wherein R.sup.1 and R.sup.2 or R.sup.2 and R.sup.3 together can form a benzene ring which optionally can be substituted by halogen, trifluoromethyl, nitro, lower-alkyl or lower alkoxy, and of their pharmaceutically acceptable salts as kynurenin-3-hydroxylase inhibitors in the control or prevention of neuro-degenerative disorders, neurological disorders resulting from an activation of the immune system, or psychiatric illnesses and, respectively, for the production of corresponding medicaments.
本发明涉及磺酰胺衍生物的使用,其一般式为 ##STR1## 其中R表示低烷基、苯基、苄基、萘基、吡啶基或噻吩基,可选地被一个或多个低烷基、低烷氧基、低烷基羰基氨基、卤素、环烷基、硝基、氨基、亚甲二氧基、苯氧基或苄氧基基团取代,芳香环可以被硝基、卤素或氨基取代,R.sup.1 -R.sup.4表示氢、卤素、羟基、低烷基、硝基、氰基、氨基、低烷氧基、苄氧基、三氟甲基或苯基,可选地被一个或多个低烷基、三氟甲基、硝基、氨基或羟基基团取代,其中R.sup.1和R.sup.2或R.sup.2和R.sup.3可以共同形成一个苯环,该苯环可选地被卤素、三氟甲基、硝基、低烷基或低烷氧基取代,以及其药学上可接受的盐,作为酪氨酸-3-羟化酶抑制剂,用于控制或预防神经退行性疾病、由免疫系统激活引起的神经系统疾病或精神疾病,分别用于生产相应的药物。
