In the current study, new 4-aryl-2-[2-((3,4-dihydro-2H-1,5-benzodioxepine-7-yl)methylene)hydrazinyl]thiazole derivatives (1–12) were synthesized and screened for their inhibitory effects on AR which was purified by diverse chromatographic methods with a yield of 1.40% and a specific activity of 2.00 EU/mg. All compounds were determined as promising AR inhibitors with the Ki values in the range of 0
醛糖还原酶(AR)催化多元醇途径中依赖NADPH的葡萄糖还原为山梨糖醇,这在糖尿病并发症的发展中起重要作用,包括白内障,视网膜病变,肾病和神经病。AR被认为是治愈这些长期糖尿病并发症的重要目标,因此,开发新的AR抑制剂是现代药物化学中的重要方法。在当前的研究中,新的4-芳基-2- [2-(((3,4-二氢-2 H -1,5-苯并二氧杂庚烷-7-基)亚甲基)肼基]噻唑衍生物(1 – 12合成)并筛选其对AR的抑制作用,其通过多种色谱方法纯化,收率为1.40%,比活性为2.00EU / mg。与槲皮素相比,所有化合物均被确定为有前途的AR抑制剂,其K i值在0.018± 0.005μM -3.746± 1.321μM范围内(K i = 7.025±1.780μM)。尤其是,检测到的最多的是4-(4-氰基苯基)-2- [2-(((3,4-二氢-2 H -1,5-苯并二氧杂庚-7-基)亚甲基)肼
