A series of aldose reductase inhibitors were prepared which were analogues of the potent, orally active inhibitor tolrestat (1). These compounds (5, 7, 9, and 10) have an extra substituent on one of the unoccupied positions on the naphthalene ring of 1. Primary amide prodrugs of several members from the series 5 and 7, namely 6 and 8, respectively, were also prepared. These compounds were evaluated
制备了一系列醛糖还原酶抑制剂,它们与有效的口服活性抑制剂托瑞司他(1)类似。这些化合物(5、7、9和10)在1的萘环的一个未占用位置上具有一个额外的取代基。分别来自5和7系列的几个成员的伯酰胺前药分别是6和8。也准备好了。在两个体外系统中对这些化合物进行了评估:从牛晶状体分离的酶制剂以评估其内在的抑制活性,在坐骨神经测定法中进行分离以测定其穿透神经组织膜的能力。还对这些化合物作为半乳糖醇在半乳糖喂养大鼠的晶状体,坐骨神经和隔膜中蓄积的抑制剂进行了体内评估。通常,系列5、7、9中的化合物 和10种是牛晶状体醛糖还原酶的有效抑制剂。来自系列5、7和9的2-卤代类似物在用4天半乳糖喂养的大鼠的神经中表现出高活性,在某些情况下,伯酰胺前药8增强了各自的体内效力羧酸7.两种2-氟衍生物8a和9a在体内具有特别高的活性,因此被选择用于其他研究。在这些试验中,通过它们的ED50判断,发现这些化合物与半乳
