Acetylcholinesterase (AChE or acetylhydrolase) is a hydrolase that hydrolyzes the neurotransmitter acetylcholine. AChE is found at mainly neuromuscular junctions and cholinergic brain synapses, where its activity serves to terminate synaptic transmission. It belongs tocarboxylesterase family of enzymes. It is the primary target of inhibition by organophosphorus compounds such as nerve agents and pesticides. AChE has a very high catalytic activity - each molecule of AChE degrades about 25000 molecules ofacetylcholine (ACh) per second, approaching the limit allowed by diffusion of the substrate. ACh is released from the nerve into the synaptic cleft and binds to ACh receptors on the post-synaptic membrane, relaying the signal from the nerve. AChE, also located on the post-synaptic membrane, terminates the signal transmission by hydrolyzing ACh. The liberated choline is taken up again by the pre-synaptic nerve and ACh is synthetized by combining with acetyl-CoA through the action of choline acetyltransferase.

Rivastigmine (tartrate)

Rivastigmine tartrate, an cholinesterase inhibitor(IC50= 5.5 uM), inhibits both butyrylcholinesterase and acetylcholinesteraseIC50 value: 5.5 uMTarget: AChERivastigmine is a parasympathomimetic or cholinergic agent for the treatment of mild to moderate dementia of the Alzheimer's type and dementia due to Parkinson's disease. The drug can be administered orally or via a transdermal patch; the latter form reduces the prevalence of side effects, which typically include nausea and vomiting. The drug is eliminated through the urine, and appears to have relatively few drug-drug interactions. Rivastigmine, a cholinesterase inhibitor, inhibits both butyrylcholinesterase and acetylcholinesterase. It is thought to work by inhibiting these cholinesterase enzymes, which would otherwise break down the brain chemical acetylcholine.
