for Alzheimer's disease, a series of deferiprone derivatives has been synthesized and evaluated in vitro with the hypothesis that they can restore the cholinergic tone and attenuate the dyshomeostasis of the metals mainly involved in the pathology. These compounds were designed as dual binding site AChE inhibitors: they possess an arylalkylamine moiety connected via an alkyl chain to a 3-hydroxy-4-pyridone

has prompted researchers to develop new ChEIs that could also reduce the oxidative stress by exhibiting antioxidant properties and by chelating the main metals involved in the disease. Recently, we developed some derivatives constituted by a 2-amino-pyrimidine or a 2-amino-pyridine moiety connected to various aromatic groups by a flexible amino-alkyl linker as new dual inhibitors of AChE and butyrylcholinesterase

A new series of pyrimidine and pyridine diamines was designed as dualbindingsiteinhibitors of cholinesterases (ChEs), characterized by two small aromatic moieties separated by a diaminoalkyl flexible linker. Many compounds are mixed or uncompetitive acetylcholinesterase (AChE) and/or butyrylcholinesterase (BChE) nanomolar inhibitors, with compound 9 being the most active on Electrophorus electricus
一系列新的嘧啶和吡啶二胺被设计为胆碱酯酶 (ChE) 的双结合位点抑制剂,其特征在于两个小的芳香部分被二氨基烷基柔性接头隔开。许多化合物是混合的或非竞争性乙酰胆碱酯酶 (AChE) 和/或丁酰胆碱酯酶 (BChE) 纳摩尔抑制剂,化合物9对电电泳AChE ( Ee AChE) ( K i = 0.312 μM)最活跃,化合物22对马 BChE ( eq BChE) ( K i= 0.099 μM)。分子对接和分子动力学研究证实了我们的化合物与酶活性位点的相互作用模式。紫外-可见光谱研究表明,这些化合物可以与 Cu 2+和 Fe 3+形成络合物,并且化合物18、20和30具有抗氧化特性。有趣的是,一些化合物还能够减少 Aβ 42和 tau 聚集,其中化合物28最有效(100 μM 时对 Aβ 42和 tau 的抑制分别为 22.3% 和 17.0% )。此外,最活跃的化合物对人脑细胞系显示出低细胞毒性,并且它们被预测为
