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. Publication Abstract from PubMed Structure-based virtual screening of two libraries containing 567981 molecules was used to discover novel, selective BuChE inhibitors, which are potentially superior symptomatic treatments in late-stage Alzheimer's disease. Compound 16 was identified as a highly selective submicromolar inhibitor of BuChE (huBuChE IC50 = 0.443 muM) with high permeability in the PAMPA-BBB model. The X-ray crystal structure of huBuChE in complex with 16 revealed the atomic-level interactions and offers opportunities for further development of the series.
