Benzo-fused heterocyclic compounds having a 5-membered ring, processes for their preperation, their use as medicaments, their use as diagnostic agents and medicaments containing them. Benzo-fused heterocyclic compounds having a 5-membered ring, of the formula I ##STR1## where X is N or CR(6); Y is oxygen, S or NR(7); A and B together are a bond or are both hydrogen, if, at the same time, X is CR(6) and Y is NR(7), one of the substituents R(1) to R(6) is a --CO--N.dbd.C(NH.sub.2).sub.2 group; the other respective substituents R(1) to R(6) are H, Hal or alkyl; up to two of the other substituents R(1) to R(6) are CN, NO.sub.2, N.sub.3, (C.sub.1 -C.sub.4)-alkoxy, CF.sub.3 ; up to one of the other substituents is R(8)--C.sub.n H.sub.2n --Z-- or phenyl; R(7) is H, alk(en)yl or R(8)--C.sub.n H.sub.2n --, and pharmaceutically tolerated salts there of, are described. A process f or the preparation of the compounds I which comprises reacting a compound of the formula II ##STR2## in which one of the substituents R(1)' to R(5)' is a --CO--L group and L is a leaving group which can easily be replaced nucleophilically, with guanidine, and, if appropriate, converting the product into the pharmacologically tolerated salt, furthermore is also described.
有5个成员环的苯并杂环化合物,其制备方法,作为药物的用途,作为诊断试剂的用途以及含有它们的药物。 公式I的有5个成员环的苯并杂环化合物,其中X为N或CR(6); Y为氧,S或NR(7); A和B共同为键合或都是氢,如果同时X是CR(6)且Y是NR(7),则R(1)至R(6)中的一个取代基是- CO- N = C(NH2)2基团;其他各自的取代基R(1)至R(6)是H,Hal或烷基;最多两个其他取代基R(1)至R(6)是CN,NO2,N3,(C1-C4)-烷氧基,CF3;最多一个其他取代基是R(8)- CnH2n- Z-或苯基; R(7)为H,烷(烯)基或R(8)- CnH2n-,以及其药物耐受的盐。还描述了一种化合物I的制备方法,其中包括将公式II的化合物反应在一起,其中R(1)'至R(5)'中的一个是- CO- L基团,L是可以轻松被亲核取代的离去基团,并且如果适当,将产物转化为药理学上耐受的盐。
