To explore new scaffolds for the treat of Alzheimer's disease appears to be an inspiring goal. In this context, a series of varyingly substituted flavonols and 4-thioflavonols have been designed and synthesized efficiently. All the newly synthesized compounds were characterized unambiguously by common spectroscopic techniques (IR, H-, C NMR) and mass spectrometry (EI-MS). All the derivatives (1-24) were evaluated in vitro for their inhibitory potential against cholinesterase enzymes. The results exhibited that these derivatives were potent selective inhibitors of acetylcholinesterase (AChE), except the compound 11 which was selective inhibitor of butyrylcholinesterase (BChE), with varying degree of IC values. Remarkably, the compounds 20 and 23 have been found the most potent almost dual inhibitors of AChE and BChE amongst the series with IC values even less than the standard drug. The experimental results in silico were further validated by molecular docking studies in order to find their binding modes with the active pockets of AChE and BChE enzymes.

Owing to the desperate need of new drugs development to treat Alzheimer's ailment the synthesis of 1-aroyl-3-(5-(4-chlorophenyl)-1,2,4-triazole-3-thioneaminylthioureas (2-6) starting from (4-amino-5-(...
Due to the role of butyrylcholinesterase (BChE) in acetylcholine hydrolysis in the late stages of the Alzheimer's disease (AD), inhibitors of butyrylcholinesterase (BChE) have been recently envisaged,...
Alkaloids have always been a great source of cholinesterase inhibitors. Numerous studies have shown that inhibiting acetylcholinesterase as well as butyrylcholinetserase is advantageous, and have bett...
An efficient, borax-catalyzed protocol for the synthesis of novel 4-aryl-substituted-4H-pyran derivatives fused to α-pyrone ring in a one-pot is described. By this achievement, some novel 4-aryl subs...
In this study, a series of novel bis-sulfone compounds (2a-2j) were synthesized by oxidation of the bis-sulfides under mild reaction conditions. The bis-sulfone derivatives were characterized by H-NM...
The level of acetylcholinesterase is suspected to correlate with postoperative delirium. The investigators therefore score patients once preoperatively and twice postoperatively with the g...
Cholinergic deficiency in the brain can be related to gait and balance problems in Parkinson disease (PD). Recent clinical trials suggested a beneficial role of acetylcholinesterase inhibi...
HMG CoA reductase inhibitors (statins) are commonly used to treat high cholesterol (HC) in both type 1 and type 2 diabetes mellitus (DM). Several studies have shown benefits of statin amon...
To establish efficacy of Lu AE58054 as adjunctive therapy to acetylcholinesterase inhibitors (AChEIs) for symptomatic treatment of patients with mild-moderate Alzheimer's disease (AD).
The purpose of this placebo-controlled study is to evaluate the safety, tolerability and pharmacokinetics of a single dosage of human butyrylcholinesterase (HuBChE) in healthy adults. HuBC...
A sulfur-containing analog of butyrylcholine which is hydrolyzed by butyrylcholinesterase to butyrate and thiocholine. It is used as a reagent in the determination of butyrylcholinesterase activity.
Compounds that bind to and inhibit enzymes involved in the synthesis of STEROIDS.
An aspect of cholinesterase (EC 184.108.40.206).
Compounds which inhibit the synthesis of proteins. They are usually ANTI-BACTERIAL AGENTS or toxins. Mechanism of the action of inhibition includes the interruption of peptide-chain elongation, the blocking the A site of ribosomes, the misreading of the genetic code or the prevention of the attachment of oligosaccharide side chains to glycoproteins.
Compounds that inhibit cell production of DNA or RNA.
