A series of novel 4-arylsulfonyl-3,4-dihydro-2(1H)-quinoxalinone-1-alkanoic acid compounds have been prepared, including their lower alkyl ester derivatives, as well as the base salts of said acids with pharmacologically acceptable cations. These particular compounds are useful in therapy as agents for the control of certain chronic diabetic complications. Typical members include those compounds derived from 3,4-di-hydro-2-(1H)-quinoxalinone-1-acetic acid wherein an unsubstituted or substituted phenylsulfonyl moiety is located at the 4-position of the molecule. Ethyl 4-benzenesulfonyl-3,4-dihydro-2(1H)-quinoxalinone-1-acetate and 4-benzenesulfonyl-3,4-dihydro-2(1H)-quinoxalinone-1-acetic acid represent typical and preferred member compounds. Methods for preparing all these compounds from known starting materials are provided.
一系列新型的4-芳基磺酰基-3,4-二氢-2(1H)-喹啉酮-1-烷酸化合物已经制备出来,包括它们的低烷基酯衍生物,以及与药理学上可接受的阳离子形成的酸的碱性盐。这些特定的化合物在治疗某些慢性糖尿病并发症的作用中非常有用。典型的成员包括从3,4-二氢-2-(1H)-喹啉酮-1-乙酸衍生的化合物,其中4-位置上有未取代或取代的苯磺酰基基团。乙基4-苯磺酰基-3,4-二氢-2(1H)-喹啉酮-1-乙酸酯和4-苯磺酰基-3,4-二氢-2(1H)-喹啉酮-1-乙酸是典型和首选的成员化合物。提供了从已知起始材料制备所有这些化合物的方法。
