The α4β2-nicotinic acetylcholine receptor(nAChR) is a ligand-gated ion channel that is distributed throughout the nervous system. It is involved in the regulation of various neurotransmitters including acetylcholine, dopamine, γ-aminobutyric acid, and norepinephrine. α4β2-nAChR plays an important role in learning, memory, cognition, attention, inflammation, and pain. A large number of studies have shown that α4β2-nAChR is an important therapeutic target for neurological diseases such as Alzheimer's disease, Parkinson's disease, epilepsy, depression, nicotine dependence, pain, etc. It is an important target in the early diagnosis and curative effect detection of neurodegenerative diseases including Alzheimer's disease. This review summarizes the role, mechanisms and related drug research advances on α4β2-nAChR ligand drugs in neurological diseases, as well as providing a theoretical basis for identifying and developing more suitable α4β2-nAChR-related compounds.
