The hypothesis that clinical side effects of the aldose reductase inhibitor (ARI) sorbinil were related to its hydantoin ring led to a bioisosteric analysis and replacement of the hydantoin by a spiro hydroxy acetic acid moiety as in 40. These hydroxy acids, compared to hydantoins, showed a similar potency increase on chroman 2-methyl substitution, a similar orthogonal relationship of acidic to aromatic
醛糖还原酶抑制剂(ARI)山梨醇的临床副作用与其乙内酰脲环有关的假说导致了生物立体分析并用螺羟基乙酸部分取代乙内酰脲,如40所示。与乙内酰脲相比,这些羟酸在苯并二氢吡喃2-甲基取代时,效价增加相似,酸性与芳族部分的正交关系相似,ARI对映选择性也相似。在该系列中,六元螺羟基乙酸乙酸阴离子阵列是螺乙内酰脲阴离子的生物等排体,可导致ARI具有出色的体内活性。像第4步那样,通过苯并二氢吡喃-2-甲基化和通过芳香族6,7-卤素取代,使体外和体内活性提高了40倍以上。将大鼠体内具有最佳急性体内活性的化合物的慢性体内活性进行了比较。
