The invention relates to compounds of formula (I) and salts thereof
wherein R¹ and R² are the same or different and are each selected from hydroxy, or a group NR⁹R¹⁰ wherein R⁹ and R¹⁰ are each hydrogen, alkyl, aryl, arylalkyl or together with the nitrogen atom to which they are attached form a ring, optionally containing a further heteroatom and optionally further substituted by alkyl, aryl or arylalkyl;
R³ is selected from hydrogen, haloalkyl, alkyl and halo, R⁴ to R⁸ are the same or different, and are each selected from hydrogen, halo, nitro, amino, sulphonamido or alkylsulphonylamino;
or R⁴ and R⁵ or R⁵ and R⁶ may together form a carbocyclic ring;
with the proviso that at least one of R⁴ to R⁸ is other than hydrogen.
The compounds may be used for the treatment or prophylaxis of a neurodegenerative or other neurological disorder of the CNS, the aetiology of which includes excessive release of the neurotransmitter glutamate.
本发明涉及公式(I)的化合物及其盐,其中R¹和R²相同或不同,分别选择自羟基或NR⁹R¹⁰基团,其中R⁹和R¹⁰各自是氢、烷基、芳基、芳基烷基或与它们所连接的氮原子一起形成一个环,可选地含有另一个杂原子,并可选地进一步被烷基、芳基或芳基烷基取代;R³选择自氢、卤代烷基、烷基和卤素,R⁴到R⁸相同或不同,分别选择自氢、卤素、硝基、氨基、磺酰胺基或烷基磺酰胺基;或R⁴和R⁵或R⁵和R⁶可以共同形成一个碳环;但至少R⁴到R⁸中的一个不是氢。这些化合物可用于治疗或预防中枢神经系统的神经退行性或其他神经疾病,其发病机制包括神经递质谷氨酸过度释放。
