flavonoids, isoxazoles and halogenated derivatives are of great interest in medicinal chemistry due to their considerable bioactivities. Therefore, this work describes the design, the synthesis and the α-amylase inhibitory potential of new halogenated flavonoid-based isoxazoles, and their biological properties. In fact, the condensation of a previously synthesized halogenated flavonol with different aryl
碳水化合物是大多数饮食中卡路里的主要来源,α-淀粉酶被认为是启动消化的主要酶之一。因此,α-淀粉酶的抑制被认为是用于治疗葡萄糖吸收障碍例如龋齿、牙周病、超重、肥胖症和糖尿病的治疗策略。另一方面,类黄酮、异恶唑和卤代衍生物由于其相当大的生物活性而在药物化学中引起了极大的兴趣。因此,这项工作描述了设计、综合和α- 新型卤化类黄酮异恶唑的淀粉酶抑制潜力及其生物学特性。事实上,先前合成的卤化黄酮醇与不同芳基腈氧化物的缩合提供了十三种新的杂化环加合物 ( 2a-m )。它们的结构通过1 H NMR、13 C NMR 和 HRMS 分析表征。还评估了这些化合物 ( 2a-m )的理化性质。在体外对新合成的环加合物的α-淀粉酶抑制活性进行了评估,并注意到了优异的结果。化合物2b (IC 50 = 16.2 ± 0.3 µM) 表现出最高的抗α-淀粉酶活性与标准物质相当(阿卡波糖,IC 50 = 15
