The invention concerns novel, pharmaceutically useful, benzheterocyclyl sulphones of the formula I: ##STR1## in which ring A may bear optional halogeno, (1-4C)alkyl or fluoro(1-4C)alkyl substituents; X is oxygen, or a group of the formula --S(O).sub.n -- or --NR.sup.1 -- in which n is zero, 1 or 2 and R.sup.1 is hydrogen, (1-4C)alkyl, (1-6C)alkanoyl, benzoyl or phenyl(1-4C)alkyl, the last two optionally substituted; Y is various linking groups defined hereinafter, such as ethylene or trimethylene; and in which the group --SO.sub.2 CH.sub.2 NO.sub.2 is located at position a, b or c in ring A; together with the non-toxic thereof. Other aspects of the invention include the production of the novel compounds by analogy processes and pharmaceutical compositions of the novel compounds for use in the treatment of diabetic complications.
本发明涉及式I的新型、具有药用价值的苯杂环磺酰基化合物:##STR1## 其中环A可以具有可选的卤素、(1-4C)烷基或氟代(1-4C)烷基取代基;X是氧,或者是式--S(O).sub.n --或--NR.sup.1--的基团,其中n为0、1或2,R.sup.1是氢、(1-4C)烷基、(1-6C)脂肪酰基、苯甲酰基或苯基(1-4C)烷基,最后两种基团可以选用取代基;Y是定义如下的各种连接基团,例如乙烯或三亚甲基;而且基团--SO.sub.2 CH.sub.2 NO.sub.2位于环A的位置a、b或c;以及其非毒性物质。本发明的其他方面包括通过类似的方法生产新型化合物和新型化合物的制药组合物,用于治疗糖尿病并发症。
