The invention provides new compounds of formula (I) ##STR1## wherein, subject to a proviso, n is zero or an integer of 1 to 3; each of R and R.sub.1, which may be the same or different, is hydrogen, halogen, trifluoromethyl or C.sub.1 -C.sub.4 alkoxy; R.sub.2 is hydrogen or C.sub.1 -C.sub.4 alkyl optionally substituted by hydroxy; each of R.sub.3 and R.sub.4 independently is hydrogen or C.sub.1 -C.sub.4 alkyl; or a pharmaceutically acceptable salt thereof; and of formula (IA) ##STR2## wherein R.sub.5 is hydrogen, halogen, trifluoromethyl or C.sub.1 -C.sub.4 alkoxy, or a pharmaceutically acceptable salt thereof, which are active on the central nervous system (CNS) and can be used in therapy as anti-epileptics, anti-Parkinson, neuroprotective, antidepressant, anti-spastic and hypnotic agents.
本发明提供了新的化合物,其化学式为(I) ##STR1## 在该式中,n为零或1至3的整数,但需满足某种条件;每个R和R.sub.1,可以相同也可以不同,分别为氢、卤素、三氟甲基或C.sub.1-C.sub.4烷氧基;R.sub.2为氢或C.sub.1-C.sub.4烷基,可选择性地被氢氧基取代;每个R.sub.3和R.sub.4独立地为氢或C.sub.1-C.sub.4烷基;或其药学上可接受的盐;以及化学式(IA) ##STR2## 在该式中,R.sub.5为氢、卤素、三氟甲基或C.sub.1-C.sub.4烷氧基,或其药学上可接受的盐,这些化合物在中枢神经系统(CNS)上具有活性,并可用于治疗癫痫、帕金森病、神经保护、抗抑郁、抗痉挛和催眠剂。
