  摘要：

  设计，合成和研究了一系列新的香豆素衍生物以抑制胆碱酯酶，包括乙酰胆碱酯酶（AChE）和丁酰胆碱酯酶（BuChE）。这项生物学研究表明，这些含有哌嗪环的化合物对AChE而不是BuChE具有明显的抑制活性。进一步的研究表明，9x作为这种结构衍生物之一，对AChE表现出最强的抑制活性，IC 50值为34 nM。此外，分子对接，流式细胞术（FCM）和蛋白质印迹试验表明9x可以诱导细胞保护性自噬以减弱H 2 O 2。诱导的神经母细胞瘤SH-SY5Y细胞死亡。这些发现凸显了一种新的方法，可用于开发针对AChE的新型潜在神经保护化合物，该化合物在未来的阿尔茨海默氏病（AD）治疗中具有自噬诱导活性。

This approach enables controlled protodecarboxylation/regioselective C–H arylation of coumain-3-carboxylic acids in one-pot using a monometallic catalytic system. A wide variety of electron-donating and -withdrawing substituents on both coumarins and arylboronic acid are tolerated under the reaction conditions and 4-aryl coumarins are constructed in high yields.

  d release of the catalyst enables the process to proceed efficiently with high enantio‐ and diastereoselectivity. Furthermore, a one‐pot procedure for either a LiAlH4‐ or NaBH4‐mediated reduction with subsequent acid‐catalyzed intramolecular cyclization of the Diels–Alder adducts was identified for the efficient formation of the chiral bridged tricyclic benzopyrans.
