4-oxadiazole-2-thiol analog (4) to afford a range of N-substituted derivatives (8a-l). The structural confirmation of all the synthetic compounds was carried out by IR, 1H-, 13C NMR, EI-MS, and CHN analysis data. All synthesized molecules (8a-l) were tested for their antidiabetic potential via inhibition of the α-glucosidase enzyme followed by their in silico study. Their cytotoxicity profile was also ascertained via
当前的研究基于通过化学转化将吲哚基丁酸(1)依次转化为吲哚基丁酸乙酯(2),吲哚基丁酰肼(3)和1,3,4-恶二唑-2-硫醇类似物(4)。在一系列平行的反应中,通过使不同的胺衍生物(5a-1)与2-溴乙酰基溴(6)反应用作亲电试剂来合成2-溴-N-苯基/芳基乙酰胺(7a-1)。然后,用亲核的1,3,4-恶二唑-2-硫醇类似物(4)处理合成的亲电试剂(7a-1),得到一系列N-取代的衍生物(8a-1)。通过IR,1 H-,13 C NMR,EI-MS和CHN分析数据进行所有合成化合物的结构确认。通过抑制α-葡萄糖苷酶,然后进行计算机模拟研究,测试了所有合成分子(8a-1)的抗糖尿病潜力。还通过溶血活性确定了它们的细胞毒性谱,并且它们都具有非常低的细胞毒性。发现化合物8h和8l最具有IC 50活性值分别为9.46±0.03 µM和9.37±0.03 µM。但是,与标准阿卡波糖(IC 50 =
