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.
该发明涉及一般式2的新的环化吲哚衍生物,其中p1 R.sub.0是具有1-4个碳原子的烷基或烷氧基,苯基烷氧基在烷氧基中具有1-3个碳原子,羟基,卤素,三氟甲基,三氟甲氧基,三氟甲硫基,或者一个基团R.sub.7 S(O).sub.p,其中R.sub.7是具有1-4个碳原子的烷基,p的值为0、1或2,或者R.sub.0是一个基团R.sub.8 R.sub.9 N,R.sub.8 R.sub.9 N--CO--CH.sub.2 --或R.sub.8 R.sub.9 --N--CO,其中R.sub.8和R.sub.9是氢或具有1-4个碳原子的烷基,或者R.sub.8 R.sub.9 N形成饱和的5-或6-成员环,n的值为0、1或2,Z与碳原子和氮原子一起形成一个由5-8个环原子组成的杂环基团,在该基团中,除了已经存在的氮原子外,还可能存在一个--CO--基团或来自N、O、S、S-O或SO.sub.2组的第二个杂原子,该环可能被1-3个具有1-4个碳原子的烷基、苯基或螺环烷基(C.sub.2 -C.sub.5)取代,或者该环可能与由5个或6个环原子组成的饱和或非饱和碳环或杂环环相连,该环可能被卤素、具有1-4个碳原子的烷基或烷氧基取代,m的值为1-5,R.sub.2、R.sub.3和R.sub.4中的一个是氢、具有1-6个碳原子的烷基、具有3-7个碳原子的环烷基、具有2-6个碳原子的烯基或者在烷基中具有1-3个碳原子的苯基烷基,另外两个基团独立地是氢或具有1-6个碳原子的烷基,以及其药用可接受的酸盐。这些化合物是“神经元”5-羟色胺(5-HT)受体的强效和选择性拮抗剂,与相关已知化合物相比,具有更持久的效果和更低的毒性。
