N-Acetic acidderivatives of 6-aryl-pyrazolo-triazin-4-ones were synthesized for evaluation as new aldosereductase inhibitors. The intrinsic activity of each compound was assessed by measuring the inhibition of enzymatic activity in an isolated pig lens enzyme preparation. All the prepared compounds exhibited a significant in vitro aldosereductaseinhibitory effect (10(-6) M less than or equal to
合成了6-芳基-吡唑并三嗪-4-酮的N-乙酸衍生物作为新的醛糖还原酶抑制剂进行评估。通过测量分离的猪晶状体酶制剂中酶活性的抑制作用来评估每种化合物的固有活性。所有制备的化合物均显示出显着的体外醛糖还原酶抑制作用(10(-6)M小于或等于IC50小于或等于10(-4)M)。此外,大多数数据集的生物活性(log 1 / IC50)可直接与电子和空间参数相关。最后,使用分子模型系统将活性最高的衍生物6c(IC50 = 2 x 10(-6)M)的空间构型与托列司他的空间构型以及醛糖还原酶抑制剂位点的药效比进行了比较。
