Acetylcholinesterase

From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history

Acetylcholinesterase is the enzyme that breaks down acetylcholine.

Inhibitors[edit | edit source]

Aceytlcholinesterase inhibitors inhibit acetylcholinesterase from breaking down acetylcholine, resulting in higher circulating levels of the neurotransmitter.

They are used to treat myasthenia gravis and postural orthostatic tachycardia, and to improve cognitive function in Alzheimer's disease[1] and Parkinson's disease.

Examples of potential therapeutic inhibitors[edit | edit source]

Compounds which function as reversible competitive or noncompetitive inhibitors of cholinesterase are those most likely to have therapeutic uses. These include:

Examples of irreversible inhibitors[edit | edit source]

Irreversible inhibitors can lead to muscular paralysis, convulsion and death by asphyxiation. Organophosphates, some insecticides, and nerve gases for chemical warfare are examples of irreversible inhibitors.[citation needed]
