Caffeine Inhibits Acetylcholinesterase, But Not Butyrylcholinesterase [PDF]

International Journal of Molecular Sciences, 2013
Caffeine is an alkaloid with a stimulant effect in the body. It can interfere in transmissions based on acetylcholine, epinephrine, norepinephrine, serotonin, dopamine and glutamate. Clinical studies indicate that it can be involved in the slowing of Alzheimer disease pathology and some other effects. The effects are not well understood. In the present

Electrochemical Biosensors based on Acetylcholinesterase and Butyrylcholinesterase. A Review

International Journal of Electrochemical Science, 2016
Two cholinesterases are known: acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). The both enzymes are presented in the body under physiological conditions and the both enzymes have broad use in pharmacology, toxicology and analyses.

Pursuing the Complexity of Alzheimer’s Disease: Discovery of Fluoren-9-Amines as Selective Butyrylcholinesterase Inhibitors and N-Methyl-d-Aspartate Receptor Antagonists

Biomolecules, 2020
Alzheimer’s disease (AD) is a complex disorder with unknown etiology. Currently, only symptomatic therapy of AD is available, comprising cholinesterase inhibitors and N-methyl-d-aspartate (NMDA) receptor antagonists. Drugs targeting only one pathological

Synthesized flavone attenuates diabetes‐induced neurodegeneration through regulation of oxidative stress and metabolic‐neurodegenerative molecular pathways

Ibrain, EarlyView.
Neuroprotective efficacy of flavone (2‐phenyl‐4H‐chromen‐4‐one). The study aimed to explore the potential of a synthetic derivative (flavone) of a phytocompound, which is involved in neuroprotection activities. Experimental strategies included the characteristics of compound, in‐silico analysis, and in vivo assessments.

Human butyrylcholinesterase polymorphism: Molecular modeling

International Journal of Risk & Safety in Medicine, 2015
BACKGROUND: Prolonged apnoea following injection of ester-containing myoralaxants was first described in 1953. Because a large part of administered succinylcholine is shortly hydrolyzed by plasma butyrylcholinesterase (BChE) under normal conditions, prolonged apnoea was attributed to deficiency in BChE.

Multi‐Targeting Ligands as Prospective Therapeutics for Alzheimer's Disease, a Prevalent Neurodegenerative Disorder: Mechanistic Insights, Emerging Targets and Drug Discovery Campaigns

Medicinal Research Reviews, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a debilitating neurodegenerative condition characterized by progressive cognitive impairment, memory deterioration, and neuronal dysfunction. Its complex pathophysiology involves multiple interlinked processes, including amyloid‐β (Aβ) aggregation, tau hyperphosphorylation, oxidative stress, neuroinflammation ...

Intranasal diamorphine population pharmacokinetics modeling and simulation in pediatric breakthrough pain

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 435-447, March 2025.
Abstract Intranasal diamorphine (IND), approved for managing breakthrough pain in the UK, has been identified as an acceptable alternative offering effective, expedient, and less traumatic analgesia for children. However, the current dose regimen in pediatric populations relies on clinical expertise while the pharmacokinetics properties are poorly ...

Emerging significance of butyrylcholinesterase

World Journal of Experimental Medicine
Butyrylcholinesterase (BChE; EC 3.1.1.8), an enzyme structurally related to acetylcholinesterase, is widely distributed in the human body. It plays a role in the detoxification of chemicals such as succinylcholine, a muscle relaxant used in anesthetic practice.

Synthesis, Structural Characterization, and Cholinesterase Inhibition of Sulfonamide Derivatives Incorporating Dipeptide Units

Journal of Chemistry
Five new sulfonamide deriatives bearing dipeptide moieties (4a-e) were synthesized and assessed for their inhibitory activity against acetylcholinesterase and butyrylcholinesterase. First, the condensation reaction of benzenesulfonyl chlorides (1a-c) and
