This invention relates to new, therapeutically active compounds of the general formula ##SPC1## In which A represents one of the groupings ##EQU1## R.sup.2 --S--, R.sup.2 --OS--, and R.sup.2 --O.sub.2 S--, R.sup.1, R.sup.2, R.sup.3, and R.sup.4 each represents hydrogen, an aliphatic radical, a cycloaliphatic radical, or an aromatically, cycloaliphatically, or heterocyclically substituted aliphatic radical, in addition to which R.sup.2 and R.sup.3 may each represent an aromatic or heterocyclic radical, and when A is ##EQU2## R.sup.1 and R.sup.2 may be linked to form a 5- to 8-membered heterocyclic ring system, which may have one or more nitrogen atoms, sulphur atoms, or oxygen atoms in addition to the nitrogen atom linked to R.sup.1 and R.sup.2 ; R.sup.5 is hydrogen or lower alkyl; and R.sup.6 is hydrogen or lower alkyl or acyl; to salts, esters, and amides of the said compounds; and to methods for the production of the compounds.
这项发明涉及一般式##SPC1##的新的具有治疗活性的化合物,其中A代表以下分组之一##EQU1##R.sup.2--S--,R.sup.2--OS--和R.sup.2--O.sub.2S--,R.sup.1,R.sup.2,R.sup.3和R.sup.4分别代表氢,脂肪基,环脂基或芳香族,环脂基或杂环基取代的脂肪基,此外R.sup.2和R.sup.3可能分别代表芳香族或杂环基,当A为##EQU2##时,R.sup.1和R.sup.2可以连接形成一个5-至8-成员的杂环系统,该系统除了与R.sup.1和R.sup.2连接的氮原子外,还可以具有一个或多个氮原子、硫原子或氧原子;R.sup.5为氢或较低的烷基;R.sup.6为氢或较低的烷基或酰基;以及所述化合物的盐、酯和酰胺;以及该化合物的生产方法。
