analogs synthesized by Claisen–Schmidt condensation were tested for inhibition of aldose reductase, which is the key enzyme in the development of secondary diabetic complications. The most active compounds exerted IC50 values within the micromolar scale, and their interactions with the enzyme were described in a molecular docking study. Antioxidant activity of several representative compounds was explored
摘要测试了通过Claisen-Schmidt缩合反应合成的Chalcones及其吡嗪类似物对醛糖还原酶的抑制作用,醛糖还原酶是继发性糖尿病并发症发展中的关键酶。活性最高的化合物的IC 50在分子对接研究中描述了微摩尔量级内的最大值,以及它们与酶的相互作用。在DPPH(2,2-二苯基-1-picylhydrazyl)分析中探索了几种代表性化合物的抗氧化活性,揭示了对在环B位置3上带有供电子甲氧基取代基的4-羟基取代衍生物的清除作用。 ,在B环及其吡嗪类似物中被羟基化和甲氧基化的新型查耳酮显示出明显的醛糖还原酶抑制活性,尽管与参考依帕司他相比更低。被测试的代表性化合物显示出中等的抗氧化活性(不超过标准Trolox的抗氧化功效)。 图形概要
