NMR) and mass spectrometry. The hybrid compounds were evaluated as aldehyde and aldose reductase inhibitors. The biological screening results identified several compounds as remarkable inhibitors of ALR1 and ALR2. Among them, compounds 9c and 9k showed excellent activity (and complete selectivity) towards the aldose reductase enzyme with IC50 values of 1.22 ± 0.67, and 2.34 ± 0.78 μM, respectively, as
为了开发新型的有效醛糖还原酶抑制剂,设计并合成了一系列1,3-二芳基吡唑同化的3-取代的4-oxo-2-thioxo-1,3-thiazolidines(9a–n)。通过药效基团整合方法获得了良好或优异的产量。新合成的吡唑-若丹宁衍生物的结构是通过容易获得的光谱方法(FTIR,1 H和13 C NMR)和质谱确定的。杂合化合物被评估为醛和醛糖还原酶抑制剂。生物学筛选结果确定了几种化合物是ALR1和ALR2的显着抑制剂。其中,化合物9c和9k与标准药物(山梨醇; IC 50 = 3.10±0.20μM)相比,对醛糖还原酶具有优异的活性(完全选择性),IC 50值分别为1.22±0.67和2.34±0.78μM 。进行了最有效的抑制剂9c的分子对接分析,以鉴定酶活性口袋内部的假定结合模式。据信,这些新发现的醛糖还原酶抑制剂代表有价值的先导结构,可进一步简化候选化合物的产生,以针对多种病理状况,最令人震惊的是长期的糖尿病并发症。
