AChE
Acetylcholinesterase (AChE) is the principal cholinergic enzyme that rapidly hydrolyzes acetylcholine at cholinergic synapses and neuromuscular junctions, thereby terminating neurotransmission and maintaining synaptic signaling fidelity[1]. Mechanistically, AChE regulates cholinergic pathway activity through efficient acetylcholine clearance, a process that is essential for normal neuronal communication and neuromuscular function[1]. Beyond its catalytic role, AChE displays multiple molecular forms and has been implicated in cellular interactions, neuronal activity modulation, and pathological states, supporting broader biological functions outside classical neurotransmission[1]. In neurodegenerative disease models, particularly Alzheimer’s disease (AD), altered cholinergic signaling is closely associated with cognitive impairment, and cholinesterase inhibition remains a major symptomatic therapeutic strategy[2][3]. Compared with the related isoform butyrylcholinesterase (BChE), AChE is the predominant cholinesterase in the brain and plays a primary role in synaptic acetylcholine hydrolysis, whereas BChE may compensate when AChE activity is reduced and exhibits distinct pathological changes during AD progression[3][4]. For experimental and translational applications, reversible and dual AChE/BChE inhibitors, including rivastigmine, are widely used to enhance cholinergic neurotransmission and investigate mechanisms underlying neurodegeneration and cognitive dysfunction[2][3].

Propoxur (Standard)
0 ImagesPropoxue (Standard) is the analytical standard of Propoxue (HY-B0916). This product is intended for research and analytical applications. Propoxur is a reversible, competitive, orally active AChE inhibitor that can cross the blood-brain barrier. Propoxur inhibits AChE activity to induce neurotoxicity, while promoting MMP-2 expression and enhancing tumor cell migration and invasion by inducing intracellular ROS generation and activating the ERK/Nrf2 signaling pathway. On the one hand, Propoxur inhibits AChE, leading to acetylcholine accumulation and causing neurological dysfunction; on the other hand, it promotes Nrf2 nuclear translocation through ROS-dependent ERK1/2 phosphorylation, and upregulates MMP-2 and other invasion-related proteins. Propoxur is also a carbamate insecticide used to combat turf, forestry, and household pests.
