Hydroxylated 6H-benzo[c]chromen-6-one derivatives (i.e., urolithins) are the main bioavailable metabolites, and biomarkers of ellagitannins present in various nutrition. Although these dietaries, the sources of urolithins, are employed in folk medicine as cognitive enhancer in the treatment of Alzheimer's Disease, urolithins have negligible potential to inhibit acetylcholinesterase and butyrylc...
In this study, we have employed in silico methodology combining double pharmacophore based screening, molecular docking, and ADME/T filtering to identify dual binding site acetylcholinesterase inhibitors that can preferentially inhibit acetylcholinesterase and simultaneously inhibit the butyrylcholinesterase also but in the lesser extent than acetylcholinesterase. 3D-pharmacophore models of ACh...
Five sesquiterpene coumarin ethers: umbelliprenin, umbelliprenin-10',11'-monoepoxide, conferone, mogoltacin and feselol were isolated from the fruits of Heptaptera cilicica. Their structures were identified by means of spectroscopic methods. AChE and BuChE inhibitory activities of the compounds were determined by molecular docking method which were confirmed by in vitro experiments. According t...
The levels of pseudocholinesterase and its nature were studied in 390 leprosy patients and 343 control subjects. The levels of the enzyme in both leprosy patients and normal controls were comparable. The study of the nature of the enzyme by determining its dibucaine number showed that a statistically significant number of lepromatous patients had the atypical variety of the enzyme compared with...
the present study reports the synthesis of a series n-substituted derivatives of brominated 2-phenitidine. first, the reaction of 2-phenitidine (1) with benzenesulfonyl chloride (2) in aqueous media yielded n-(2-ethoxyphenyl) benzenesulfonamide (3), which was then subjected to bromination with bromine in the presence of glacial acetic acid to give n-(4,5-dibromo-2-ethoxyphenyl)benzenesulfonamid...
Butyrylcholinesterase (BChE) is a serine hydrolase (EC 3.1.1.8) which can be found in most animal tissues. This enzyme has a broad spectrum of efficacy against organophosphorus compounds, which makes it a prime candidate for the role of stoichiometric bioscavenger. Development of a new-age DNA-encoded bioscavenger is a vival task. Several transgenic expression systems of human BChE were develop...
A new assay has been developed for detection of butyrylcholinesterase (EC 3.1.1.8) activity based upon the change in absorbance of phenol red, caused by the r e l ease of bu ty r i c acid from the substrate. Using c o m m e r c i a l l y avai lable enzyme prepared from horse serum, linear, dose-related decreases in absorbance were obtained, generally with correlation values of 0.965 or greater....
Isosorbide-2-carbamate-5-esters are highly potent and selective butyrylcholinesterase inhibitors with potential utility in the treatment of Alzheimer's Disease (AD). They are stable in human plasma but in mouse plasma they undergo hydrolysis at the 5-ester group potentially attenuating in vivo potency. In this paper we explore the role of the 5-position in modulating potency. The focus of the s...
Recombinant proteins represent a large sector of the biopharma market. Determination of the main elimination pathways raises the opportunities to significantly increase their half-lives in vivo. However, evaluation of biodegradation of pharmaceutical biopolymers performed in the course of pre-clinical studies is frequently complicated. Noninvasive pharmacokinetic and biodistribution studies in ...
