  Synthesis and biological evaluation of 2-arylbenzofuran derivatives as potential anti-Alzheimer’s disease agents

  摘要：

  Alzheimer's disease (AD) is a type of progressive dementia caused by degeneration of the nervous system. A single target drug usually does not work well. Therefore, multi-target drugs are designed and developed so that one drug can specifically bind to multiple targets to ensure clinical effectiveness and reduce toxicity. We synthesised a series of 2-arylbenzofuran derivatives and evaluated their in vitro activities. 2-Arylbenzofuran compounds have good dual cholinesterase inhibitory activity and β-secretase inhibitory activity. The IC50 value of compound 20 against acetylcholinesterase inhibition (0.086 ± 0.01 µmol·L-1) is similar to donepezil (0.085 ± 0.01 µmol·L-1) and is better than baicalein (0.404 ± 0.04 µmol·L-1). And most of the compounds have good BACE1 inhibitory activity, of which 3 compounds (8, 19 and 20) show better activity than baicalein (0.087 ± 0.03 µmol·L-1). According to experimental results, 2-arylbenzofuran compounds provide an idea for drug design to develop prevention and treatment for AD.

  cross‐coupling reaction. In the presence of tetra‐(n‐butyl)ammonium fluoride (TBAF), palladium(II) acetate [Pd(OAc)2] and triphenylphosphine (PPh3), the reaction of 2‐(gem‐dibromovinyl)phenols(thiophenols) with phenyl(trialkoxy)silanes proceeded smoothly and generated the corresponding products with good yields in one‐pot. It should be noted that TBAF plays an important role in the tandem reaction.

  通过有效的串联消除-分子内加成-Hiyama交叉偶联反应制备了2-芳基苯并呋喃（噻吩）。在四（正丁基）氟化铵（TBAF），乙酸钯（II）[Pd（OAc）2 ]和三苯膦（PPh 3）的存在下，2-（宝石-二溴乙烯基）苯酚（硫酚）的反应与苯基（三烷氧基）硅烷的合成过程顺利进行，一次生成的相应产物收率很高。应当指出，TBAF在串联反应中起重要作用。
