This compound, Velnacrine, is a potent acetylcholinesterase (AChE) inhibitor (IC50 = 3.27 μM), primarily used in neurodegenerative disease research and pharmaceutical development. It is a derivative of Tacrine, designed to improve efficacy and reduce hepatotoxicity. In pharmacology, it enhances cholinergic neurotransmission by blocking AChE, making it a key candidate for treating Alzheimer’s disease and cognitive impairment. It is widely used in laboratory studies to explore cholinergic system mechanisms and screen therapeutic agents. Additionally, it serves as a critical intermediate in synthesizing other bioactive acridine derivatives for neurological disorder treatments. With high biological activity and clear mechanism, it is favored by research institutions and pharmaceutical enterprises. As aging populations increase, demand for anti-dementia drugs grows, expanding its application in academic research and drug development.

This chemical is irritating and biologically active, requiring strict protection during handling, storage, and transportation. Direct skin contact may cause redness, itching, or dermatitis. Eye contact can lead to stinging, swelling, or tearing. Inhalation of dust may irritate the respiratory tract, causing cough or sore throat. Ingestion may cause nausea, vomiting, or gastrointestinal discomfort; do not induce vomiting—seek medical help immediately. Operators must wear chemical-resistant gloves, sealed goggles, and dust masks, working in well-ventilated areas. Store in cool, dry, dark places with sealed containers, away from heat, flames, oxidants, and strong acids. Do not store with food or daily items. Waste must comply with hazardous waste regulations. Avoid prolonged exposure. Equip work areas with emergency flushing facilities and first-aid kits. All personnel must complete safety training before operation.
