Abstract:Worldwide use of
organophosphate pesticides as agricultural chemicals
aims to maintain a stable food supply, while their toxicity remains
a major public health concern. A common mechanism of acute neurotoxicity
following organophosphate pesticide exposure is the inhibition of
acetylcholinesterase (AChE). To support Next Generation Risk Assessment
for public health upon acute neurotoxicity induced by organophosphate
pesticides, physiologically based kinetic (PBK) modeling-facilitated
quantitative

“…We adopted pH = 6 to simulate all apo and ligand bound systems because the p K a of the piperidine N -carboxylic acid moiety (R–N–COOH) of DB08385 was found to be ∼5.8, obtained from the MolGpka web server, 46 a small molecule p K a predictor based on graph-convolutional neural network, which has been widely used in recent studies. 47–50 In this context, DB08385 and its variants were modelled in both the protonated and deprotonated forms with the MexB L protomer. Some important studies 11,51 extensively discussed about the MexAB–OprM antibiotic transport activity and functioning mechanism at different pH values, where it was considered that the proton-powered AcrB or MexB pump would be highly active in a lower pH environment.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
