  A novel series of coumarin derivatives were designed, synthesized and investigated for inhibition of cholinesterase, including acetyl cholinesterase (AChE) and butyrylcholinesterase (BuChE). This biological study showed that these compounds containing piperazine ring had significant inhibition activities on AChE rather than BuChE. Further study suggested that 9x, as one of this kind of structure derivative

  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。

  In an attempt to identify potential new agents that are active against HIV-1 IN, a series of novel coumarin-3-carbohydrazide derivatives were designed and synthesised. The toxicity profiles of these compounds showed that they were non-toxic to human cells and they exhibited promising anti-HIV-1 IN activities with IC50 values in nM range. Also, an accompanying molecular modeling study showed that the

  BuChE. The in vitro assessment of the synthesized compounds 4a-o revealed that most of them had significant activity toward AChE. The SAR study demonstrated that the introduction of benzyloxy moiety on the 7-position of coumarin scaffold can improve the anti-AChE activity. The best result was obtained with 7-(4-fluorobenzyl)oxy moiety in the case of compound 4o, displaying IC50 value of 0.16 μM. Based on

  A highly selective color sensor based on naphthalimide and coumarin was reported. Upon addition of F–, the solution color changed from pale yellow to deep blue. The sensor shows excellent selectivity against other common anions. The underlying mechanism for the color change is based on the deprotonation/protonation of the dye. Frontier molecular orbitals analysis gives further insight about the signaling mechanism.

Moreover, the new compounds were tested as potential antineurodegenerative agents via their ability to act as acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitors. Compared to the commercial standards, only a few compounds demonstrated moderate AChE and BuChE activities. Moreover, the novel derivatives were tested for
