Acetylcholinesterase (AChE) inhibitors block the enzyme that breaks down acetylcholine at cholinergic synapses. By ending acetylcholine signaling within milliseconds, AChE controls transmission in the brain and at the neuromuscular junction. The 1991 crystal structure of AChE from Torpedo californica showed the active site at the base of a deep, narrow gorge. AChE also has non-catalytic roles, which broaden its interest beyond synaptic transmission. Inhibitors here include donepezil hydrochloride and galanthamine hydrobromide, which are reversible inhibitors. The carbamates rivastigmine tartrate and neostigmine bromide, used in studies of cholinergic signaling and neurodegeneration, are also listed.
