diabetes. In the current study, new molecules as a hybrid of isoxazole and dibenzazepine scaffolds were designed, based on their literature as antidiabetic agents. For this, a series of dibenzazepine-linked isoxazoles (33-54) was prepared using Nitrile oxide-Alkyne cycloaddition (NOAC) reaction, and evaluated for their α-glucosidase inhibitory activities to explore new hits for treatment of diabetes
α-葡萄糖苷酶抑制是控制糖尿病高血糖的有效方法。在目前的研究中,根据他们作为抗糖尿病药物的文献,设计了作为异恶唑和二苯并氮杂支架混合体的新分子。为此,使用氧化腈-炔环加成 (NOAC) 反应制备了一系列二苯并氮杂连接的异恶唑 ( 33-54 ),并评估了它们的α-葡萄糖苷酶抑制活性,以探索治疗糖尿病的新方法。大多数化合物显示出对强效的抑制效力α葡糖苷酶(EC 3.2.1.20)的酶(IC 50 = 35.62±1.48至333.30±1.67 μ M)使用阿卡波糖作为参考药物(IC 50= 875.75 ± 2.08 µ M)。还确定了活性异恶唑的构效关系、动力学和分子对接研究,以研究酶-抑制剂相互作用。化合物33,40,41,46,48-50,和54显示结合与关键的氨基酸残基相互作用α葡糖苷酶的酶,如Lys156,Ser157,Asp242和Gln353。
