4'-imidazolidine]-2',5'-diones were synthesized stereoselectively from (+)-, (-)-, and (+/-)-6-fluoro-3, 4-dihydro-4-oxo-2H-1-benzopyran-2-carboxylic acid [(+)-1, (-)-1, and (+/-)-1], respectively, for evaluation as new aldose reductase inhibitors. Among these compounds, the 2S,4S compounds were found to be more potent inhibitors of aldose reductase in vitro and in vivo than the corresponding 2R,4R
由(+)-,(-)立体选择性合成旋光和外消旋的2-取代的6-氟-2,3-二氢螺[4H-1-苯并吡喃-4,4'-咪唑烷] -2',5'-二酮。 -和(+/-)-6-氟-3、4-二氢-4-氧代-2H-1-苯并吡喃-2-羧酸[(+)-1,(-)-1和(+ / -)-1],分别作为新的醛糖还原酶抑制剂进行评估。在这些化合物中,发现2S,4S化合物在体外和体内是比相应的2R,4R对映异构体更有效的醛糖还原酶抑制剂。氯甲基化合物[(+)-5]在抑制大鼠晶状体白内障形成和大鼠坐骨神经中多元醇积累方面表现出强大的活性。
