The present invention relates to novel 4- or 5-(substituted sulfonyl)methyl-3(2H)-furanones having the formula (I) ##STR1## wherein R.sup.1 and R.sup.2 are independently alkyl containing 1 to 6 branched or straight chain carbon atoms, phenyl, or halogen substituted phenyl; or R.sup.1 and R.sup.2 are joined by 5 to 7 carbon atoms; R.sup.3 and R.sup.4 are independently hydrogen, alkyl containing 1 to 6 branched or straight chain carbon atoms or R.sup.3 and R.sup.4 are joined by 4 to 6 carbon atoms; R.sup.5 is alkyl containing 1 to 6 branched or straight chain carbon atoms, phenyl, naphthyl or substituted phenyl wherein the substituent is selected from the group consisting of alkyl containing 1 to 6 branched or straight chain carbon atoms, halogen, methoxy, nitro and acetamide which possess blood-glucose lowering activity and inhibit cholesterol absorption, and which have cytoprotective and antiulcer activity, to processes for preparation thereof, pharmaceutical compositions comprising the same, and to the method of using the same in the reduction of excess glucose and cholesterol and of treatment of ulcers in human beings and animals.
本发明涉及具有以下式(I)的新型4-或5-(取代磺酰基)甲基-3(2H)-呋喃酮:
其中R.sup.1和R.sup.2分别是独立的,包含1至6个支链或直链碳原子的烷基,苯基,或卤素取代的苯基;或者R.sup.1和R.sup.2由5至7个碳原子连接;R.sup.3和R.sup.4分别是独立的氢,包含1至6个支链或直链碳原子的烷基,或者R.sup.3和R.sup.4由4至6个碳原子连接;R.sup.5是包含1至6个支链或直链碳原子的烷基,苯基,萘基或取代的苯基,其中取代基选择自包含1至6个支链或直链碳原子的烷基,卤素,甲氧基,硝基和乙酰胺的基团,具有降低血糖和抑制胆固醇吸收的活性,并具有细胞保护和抗溃疡活性,以及制备这些化合物的方法,包括相同的药物组合物,以及在人类和动物中减少多余葡萄糖和胆固醇以及治疗溃疡的方法。
