The invention relates to new anellated indole derivatives of general formula 2, ##STR1## wherein p1 R.sub.0 is alkyl or alkoxy having 1-4 C-atoms, phenylalkoxy having 1-3 C-atoms in the alkoxy group, hydroxy, halogen, trifluoromethyl, trifluoromethoxy, trifluoromethylthio, or a group R.sub.7 S(O).sub.p, wherein R.sub.7 is alkyl having 1-4 C-atoms and p has the value 0, 1 or 2, or R.sub.0 is a group R.sub.8 R.sub.9 N, R.sub.8 R.sub.9 N--CO--CH.sub.2 -- or R.sub.8 R.sub.9 --N--CO wherein R.sub.8 and R.sub.9 are hydrogen or alkyl having 1-4 C-atoms or R.sub.8 R.sub.9 N forms a saturated 5- or 6-membered ring and n has the value 0, 1 or 2, Z together with the carbon atom and nitrogen atom to which Z is bound and the intermediate carbon atom, forms a heterocyclic group consisting of 5-8 ring atoms, in which, in addition to the nitrogen atom already present, a --CO--group or a second hetero atom from the group N, O, S, S-O or SO.sub.2 may be present, which ring may be substituted with 1-3 alkyl groups having 1-4 C-atoms, a phenyl group or a spiroalkyl group (C.sub.2 -C.sub.5), or which ring may be anellated with a saturated or non-saturated carbocyclic or heterocyclic ring which consists of 5- or 6-ring atoms and which may be substituted with halogen, alkyl or alkoxy having 1-4 C-atoms, and m has the values 1-5, one of the groups R.sub.2, R.sub.3 and R.sub.4 is hydrogen, alkyl having 1-6 C-atoms, cycloalkyl having 3-7 C-atoms, alkenyl having 2-6 C-atoms or phenylalkyl having 1-3 C-atoms in the alkyl group, and the two other groups independently of each other are hydrogen or alkyl having 1-6 C-atoms, and the pharmaceutically acceptable acid addition salts thereof. These compounds are strong and selective antagonists of "neuronal" 5-hydroxytryptamine (5-HT) receptors, and have a considerably longer-lasting effect and lower toxicity in comparison with related known compounds.
本发明涉及一种新的环化吲哚衍生物,其通式为2,其中p1R0是具有1-4个C原子的烷基或烷氧基,具有1-3个C原子的苯基烷氧基,羟基,卤素,三氟甲基,三氟甲氧基,三氟甲基硫基或R7S(O)p基团,其中R7是具有1-4个C原子的烷基,p的值为0、1或2,或R0是R8R9N基团,R8R9N-CO-CH2-基团或R8R9-N-CO基团,其中R8和R9是氢或具有1-4个C原子的烷基,或R8R9N形成饱和的5-或6-成员环且n的值为0、1或2,Z与其所结合的碳原子和氮原子以及中间的碳原子一起形成由5-8个环原子组成的杂环基团,其中除了已经存在的氮原子外,还可以存在一个-CO-基团或来自N、O、S、S-O或SO2的第二个杂原子,该环可以用具有1-4个C原子的1-3个烷基基团,苯基或螺环烷基(C2-C5)取代,或者该环可以与由5-或6个环原子组成的饱和或非饱和碳环或杂环环并联,该环可以用卤素、具有1-4个C原子的烷基或烷氧基取代,m的值为1-5,R2、R3和R4中的一个是氢,具有1-6个C原子的烷基,具有3-7个C原子的环烷基,具有2-6个C原子的烯基或具有1-3个C原子的苯基烷基,而另外两个基团独立地是氢或具有1-6个C原子的烷基,并且其药学上可接受的酸盐。这些化合物是“神经”5-羟色胺(5-HT)受体的强效和选择性拮抗剂,并且与相关已知化合物相比,具有更长的持续作用时间和更低的毒性。
