Abstract

A novel series of boron-containing compounds were designed, synthesized and evaluated as multi-target-directed ligands against Alzheimer's disease. The biological activity results demonstrated that these compounds possessed a significant ability to inhibit self-induced Aβ aggregation (20.5-82.8%, 20 μM) and to act as potential antioxidants (oxygen radical absorbance capacity assay using fluorescein (ORAC-FL) values of 2.70-5.87). In particular, compound is a potential lead compound for AD therapy (IC = 3.41 μM for self-induced Aβ aggregation; ORAC-FL value = 4.55). Compound also functions as a metal chelator. These results indicated that boron-containing compounds could be new structural scaffolds for the treatment of AD.

摘要

设计、合成了一系列新型含硼化合物,并将其作为针对阿尔茨海默病的多靶点导向配体进行了评估。生物活性结果表明,这些化合物具有显著抑制自身诱导的Aβ聚集的能力(20 μM时为20.5 - 82.8%),并可作为潜在的抗氧化剂(使用荧光素的氧自由基吸收能力测定(ORAC-FL)值为2.70 - 5.87)。特别地,化合物 是AD治疗的潜在先导化合物(自身诱导的Aβ聚集的IC = 3.41 μM;ORAC-FL值 = 4.55)。化合物 还可作为金属螯合剂。这些结果表明,含硼化合物可能是治疗AD的新型结构骨架。
