The power of chosen carbamates and hydrazinium derivatives (carbazates) to inhibit the hydrolysis of acetylthiocholine by butyrylcholinesterase or acetylcholinesterase was tested. The determined pI50 values (= negative logarithm of the molar concentration inhibiting the enzyme activity by 50%) of the tested substances were compared with pI50 values of the commercially used drugs for the Alzheim...
Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) are thought to be the result of a gene duplication event early in vertebrate evolution. To learn more about the evolution of these enzymes, we expressed in vitro, characterized, and modeled a recombinant cholinesterase (ChE) from a teleost, the medaka Oryzias latipes. In addition to AChE, O. latipes has a ChE that is different from ei...
Acetylcholinesterase (AChE), a serine hydrolase, is potentially susceptible to inactivation by phenylmethylsulfonyl fluoride (PMSF) and benzenesulfonyl fluoride (BSF). Although BSF inhibits both mouse and Torpedo californica AChE, PMSF does not react measurably with the T. californica enzyme. To understand the residue changes responsible for the change in reactivity, we studied the inactivation...
Abstract Alzheimer’s disease (AD) is a multifactorial incurable neurodegenerative disorder. To date, cholinesterase inhibitors (ChEI) are the mainstay line of treatment to ameliorate symptoms AD. Tacrine and donepezil considered two important cornerstones anti-dementia drugs. Accordingly, novel series hexahydrobenzothienocyclopentapyridines, octahydrobenzo-thienoquinolines, hexahydrocyclopenta(...
To date there is no diagnostic biomarker for mild stroke, although elevation of inflammatory biomarkers has been reported at early stages. Previous studies implicated acetylcholinesterase (AChE) involvement in stroke, and circulating AChE activity reflects inflammatory response, since acetylcholine suppresses inflammation. Therefore, carriers of polymorphisms that modify cholinergic activity sh...
