tested for their inhibitory activity against aldosereductase (ALR2). These derivatives were found to be potentaldosereductaseinhibitors with IC50 values ranging from 0.038 μM to 11.29 μM. Most but not all of them showed a strong ALR2 inhibition activity and significant selectivity, which were further supported by docking studies. Of these inhibitors, compound 7d exhibited highest inhibition activity
合成了一系列的吡啶并[2,3- e ]-[1,2,4]-噻二嗪1,1-二氧化物乙酸衍生物,并测试了其对醛糖还原酶(ALR2)的抑制活性。发现这些衍生物是有效的醛糖还原酶抑制剂,IC 50值为0.038μM至11.29μM。它们中的大多数但不是全部都显示出强大的ALR2抑制活性和显着的选择性,对接研究进一步证明了这一点。在这些抑制剂中,化合物7d表现出最高的抑制活性。结构-活性关系研究表明,在吡啶并噻二嗪支架中需要具有吸电子取代基的N2-苄基和N4-乙酸基。

Abstract 2-Aminopyridine-3-sulfonyl chlorides undergo a reaction with tertiary amines in the presence of air to produce sulfonylethenamines. The 2-aminopyridine-3-sulfonyl chloride apparently plays a dual role in the process promoting the aerobic oxidation of the amine and electrophilically trapping the resulting enamine.
