应用
BChE活性的选择性抑制可用于对有机磷酸酯的检测。 其在有机磷酸酯毒性治疗中的用途已有探究。据报道，人血中BChE的水平与对潜在毒性神经毒剂的防护程度有关。 胆碱酯酶在阿尔茨海默病中的作用也已有研究。
生化/生理作用
丁酰胆碱酯酶 (BChE) 是一种丝氨酸水解酶，结构与乙酰胆碱酯酶 (AChE) 相似，但底物特异性和抑制剂敏感性不同。与 AChE 不同，BChE 能有效地水解较大的胆碱酯，如丁酰胆碱和苯甲酰胆碱。该酶是一种四聚体糖蛋白，具有 4 个相等的亚单位（各 110 kDa）。该酶可被 Ca 2 + 和 Mg 2 + 激活，在 pH 6.0-8.0 范围内活性恒定。可被甜菜碱、尼古丁、有机磷酸盐和氨基甲酸酯抑制。
单位定义
在pH8.0，37℃条件下，一个单位每分钟可将1.0μmole丁酰胆碱水解为胆碱和丁酸盐。使用丁酰胆碱作为底物获得的活性是使用乙酰胆碱作为底物所获得的活性的约2.5倍。

Alzheimer's disease (AD) is a neurodegenerative disorder. The disease is characterized by dementia, memory impairment, cognitive impairment, and speech impairment. Cholinesterases (ChEs; AChE, acetylcholinesterase and BChE, butyrylcholinesterase) inhibitors and their benefits of cholinergic replacement in the treatment of AD have

Current studies have found that butyrylcholinesterase (BuChE) replaces the biological function of acetylcholinesterase (AChE) in the late stage of Alzheimer's disease. Species in the genus of Fallopia, rich in polyphenols with diverse chemical structures and significant biological activities, are considered

The present study describes the synthesis, pharmacological evaluation (BChE/AChE inhibition, Aβ antiaggregation, and neuroprotective effects), and molecular modeling studies of novel 2-[4-(4-substitutedpiperazin-1-yl)phenyl]benzimidazole derivatives. The alkyl-substituted derivatives exhibited selective inhibition on BChE with varying efficiency. Compounds 3b and 3d were found
