less reactive functional groups under catalyst-free conditions is an interesting aspect and requires a typical protocol. Herein, we report the synthesis of various primary, secondary, and tertiary amines through hydroboration of amides using pinacolborane under catalyst-free and solvent-freeconditions. The deoxygenative hydroboration of primary and secondary amides proceeded with excellent conversions

synthesized and evaluated as innovative multifunctionalagentsagainstAlzheimer'sdisease. In vitro biological assays indicated that most of the hybrids were endowed with great AChE inhibitory activity, excellent antioxidant activity and moderate Aβ1-42 aggregation inhibition. Taken both efficacy and balance into account, 12a was identified as the optimal multifunctional ligand with significant inhibition
基于多靶点定向配体方法,通过两轮筛选,设计、合成了一系列2-氨基烷基-6-(2-羟基苯基)哒嗪-3( 2H )-one衍生物作为抗阿尔茨海默病的创新多功能药物. 体外生物学试验表明,大多数杂种具有很强的 AChE 抑制活性、优异的抗氧化活性和适度的 A β 1-42聚集抑制作用。综合考虑功效和平衡,12a被确定为具有显着抑制AChE的最佳多功能配体(Ee AChE,IC 50 = 0.20 μM;Hu AChE,IC 50 = 37.02 nM) 和抗 A β活性( 自诱导 A β 1-42聚集的 IC 50 = 1.92 μM;A β 1-42原纤维分解的 IC 50 = 1.80 μM ; Cu 2的 IC 50 = 2.18 μM + -诱导的 A β 1-42聚集;对于 Cu 2+ -诱导的 A β 1-42原纤维的解聚,IC 50 = 1.17 μM ;对于Hu AChE
