Thirty benzofuran-2-yl(phenyl)methanones 1–30 were synthesized and characterized their structures by spectroscopic techniques. Substituted phenacyl bromide and different derivatives of 2-hydroxy-benzaldehyde treated in the presence of anhydrous K2CO3 in acetonitrile at room temperature to afford the desired benzofurans 1–30. All compounds were screened for their in vitro α-amylase inhibitory and radical
三十苯并呋喃-2-基(苯基)甲酮1 - 30合成,并通过光谱技术,其特征在于它们的结构。取代的苯甲酰甲基溴和无水K的存在下处理2-羟基-苯甲醛的不同衍生物2 CO 3在室温下在乙腈中反应,得到所需的苯并呋喃1 - 30。筛选所有化合物的体外α-淀粉酶抑制和自由基清除(DPPH和ABTS)活性。结果表明,对位取代的化合物比α-的IC 50值范围大的活性更高。-淀粉酶抑制(IC 50 = 18.04–48.33 µM),DPPH(IC 50 = 16.04–32.33 µM)和ABTS(IC 50 = 16.99–33.01 µM)自由基清除活性。将活性结果分别与α-淀粉酶的标准阿卡波糖(IC 50 = 16.08±0.07 µM),DPPH和ABTS自由基清除活性的抗坏血酸(IC 50 = 15.08±0.03和15.09±0.17 µM)进行比较。动力学研究预测,所有化合物均遵循
