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.
这项发明涉及具有以下式I的新型、药用的苯杂环砜化合物:其中环A可能带有可选的卤素、(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为零、1或2,R.sup.1是氢、(1-4C)烷基、(1-6C)烷酰基、苯甲酰基或苯基(1-4C)烷基,最后两者可选择性地取代;Y是下文定义的各种连接基团,如乙烯或三亚甲基;以及基团--SO.sub.2 CH.sub.2 NO.sub.2 位于环A的位置a、b或c;以及其无毒物质。该发明的其他方面包括通过类似的方法制备新型化合物以及用于治疗糖尿病并发症的新型化合物的药物组合物。
