Disease

CHLE_HUMAN Defects in BCHE are the cause of butyrylcholinesterase deficiency (BChE deficiency) [MIM:177400. BChE deficiency is a metabolic disorder characterized by prolonged apnoea after the use of certain anesthetic drugs, including the muscle relaxants succinylcholine or mivacurium and other ester local anesthetics. The duration of the prolonged apnoea varies significantly depending on the extent of the enzyme deficiency. BChE deficiency is a multifactorial disorder. The hereditary condition is transmitted as an autosomal recessive trait.

Function

CHLE_HUMAN Esterase with broad substrate specificity. Contributes to the inactivation of the neurotransmitter acetylcholine. Can degrade neurotoxic organophosphate esters.[1] [2]

Publication Abstract from PubMed

We have identified tryptophan-based selective nanomolar butyrylcholinesterase (BChE) inhibitors. They are defined according to their chemical modularity, novel binding mode revealed by five solved crystal structures with human BChE, low cytotoxicity, and predicted permeability of the blood-brain barrier. Altogether, these factors indicate their potential as unique lead compounds for symptomatic therapy against Alzheimer's disease.
