A method of treating a mammalian subject for Parkinson's disease or to provide a central muscle relaxant effect, which comprises the step of administering to the mammalian subject in need of the treatment, a therapeutically effective amount of a compound of the Formula (I) ##STR1## wherein m is 1,2 or 3; R.sub.1 and R.sub.2 each independently stand for hydrogen, C.sub.1 to C.sub.4 straight or branched chain alkyl, C.sub.1 to C.sub.4 alkoxy, C.sub.5 to C.sub.7 cycloalkyl, or halogen; and B is a 5- or 6-membered saturated or unsaturated heterocyclic group containing a nitrogen heteroatom, the heterocyclic group being bound through its heterocyclic nitrogen atom to the remainder of the compound, and which can contain one or two additional heteroatoms selected form the group consisting of an oxygen heteroatom, a sulfur heteroatom, and one or two additional nitrogen heteroatoms, which may be as an .dbd.N--, --NH-- or --NR-- group, where R is a C.sub.1 to C.sub.5 alkyl or C.sub.1 to C.sub.5 alkycarbonyl group, the nitrogen-containing heterocyclic group is unsubstituted or substituted on one of its carbon atoms by C.sub.1 to C.sub.4 alkyl or C.sub.1 to C.sub.4 alkoxycarbonyl; or a pharmaceutically acceptable salt thereof.
一种治疗哺乳动物主体帕
金森病或提供中枢肌肉松弛效应的方法,包括向需要治疗的哺乳动物主体施用化合物的有效治疗量,该化合物为式(I)##STR1## 其中m为1、2或3;R.sub.1和R.sub.2分别独立代表氢、C.sub.1到C.sub.4直链或支链烷基、C.sub.1到C.sub.4烷氧基、C.sub.5到C.sub.7环烷基或卤素;B为含有氮杂原子的5-或6-成员饱和或不饱和杂环基,该杂环基通过其杂环氮原子与化合物的其余部分结合,并且可以包含来自氧杂原子、
硫杂原子和一到两个额外氮杂原子的群组中选择的一个或两个额外杂原子,可能是作为.dbd.N--,--NH--或--NR--基团,其中R为C.sub.1到C.sub.5烷基或C.sub.1到C.sub.5烷基羰基基团,含氮杂环基未取代或在其碳原子之一上取代为C.sub.1到C.sub.4烷基或C.sub.1到C.sub.4烷氧羰基;或其药学上可接受的盐。
