The invention relates to compounds of formula I and pharmaceutically acceptable salts and in vivo hydrolysable esters and amides thereof and processes for their preparation, their use as therapeutic agents and pharmaceutical compositions containing them. ##STR1## In formula I, A is a ring system in which the --CH(R.sup.3)N(R.sup.2)B--R.sup.1 and --OR.sup.4 groups are positioned in a 1,2 relationship to one another on ring carbon atoms. B is a ring system having R.sup.1 in a 1,3 or 1,4 relationship with the --CH(R.sup.3)N(R.sup.2)-- linking group. R.sup.2 is hydrogen or C.sub.1 -C.sub.6 -alkyl, R.sup.3 is hydrogen, methyl or ethyl, and R.sup.4 is C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -cycloalkyl-C.sub.1 -C.sub.3 -alkyl, C.sub.3 -C.sub.7 -cycloalkyl, N-oxides of --NR.sup.2, where chemically possible, or S-oxides of sulphur containing rings, where chemically possible. A, B, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 may be substituted, as defined in the specification.
该发明涉及公式I的化合物及其药学上可接受的盐和体内可水解的酯和酰胺,以及它们的制备方法、作为治疗剂的用途和含有它们的药物组合物。在公式I中,A是一个环系统,其中--CH(R^3)N(R^2)B--R^1和--OR^4基团在环碳原子上以1,2的关系定位。B是一个具有R^1在与--CH(R^3)N(R^2)--连接基团的1,3或1,4关系的环系统。R^2是氢或C1-C6-烷基,R^3是氢、甲基或乙基,R^4是C1-C6-烷基、C1-C6-环烷基-C1-C3-烷基、C3-C7-环烷基、--NR^2的N-氧化物(在化学上可能的情况下)或含硫环的S-氧化物(在化学上可能的情况下)。A、B、R^1、R^2、R^3和R^4可以被取代,如规范中定义的那样。
