Two Step Synthesis of a Non-symmetric Acetylcholinesterase Reactivator [PDF]

open access: goldMolecules, 2007
The newly developed and very promising acetylcholinesterase reactivator (E)-1- (2-hydroxyiminomethylpyridinium)-4-(4-hydroxyiminomethylpyridinium)-but-2-ene dibromide was prepared using two different pathways via a two-step synthesis involving the ...

Pyridinium-2-carbaldoximes with quinolinium carboxamide moiety are simultaneous reactivators of acetylcholinesterase and butyrylcholinesterase inhibited by nerve agent surrogates [PDF]

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2021
The pyridinium-2-carbaldoximes with quinolinium carboxamide moiety were designed and synthesised as cholinesterase reactivators. The prepared compounds showed intermediate-to-high inhibition of both cholinesterases when compared to standard oximes. Their

A rapid in vitro assay for evaluating the effects of acetylcholinesterase inhibitors and reactivators in the rat basolateral amygdala [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2022
We established a novel brain slice assay to test the ability of acetylcholinesterase (AChE) reactivators to prevent ACh-induced M1 muscarinic acetylcholine receptor (mAChR) dependent hyperexcitability observed after exposure to the organophosphate (OP ...

Rezatapopt: A promising small-molecule “refolder” specific for TP53Y220C mutant tumors [PDF]

open access: yesNeoplasia: An International Journal for Oncology Research
Inactivation of p53 due to mutation is observed in approximately half of all human cancer cases, therefore, restoration of the tumor suppressor function of oncogenic p53 mutants represents an attractive and rational therapeutic approach.

Deep learning untangles the resistance mechanism of p53 reactivator in lung cancer cells [PDF]

open access: yesiScience, 2023
Summary: Tumor suppressor p53 plays a pivotal role in suppressing cancer, so various drugs has been suggested to upregulate its function. However, drug resistance is still the biggest hurdle to be overcome.

Reactivation of Human Acetylcholinesterase and Butyrylcholinesterase Inhibited by Leptophos-Oxon with Different Oxime Reactivators in Vitro [PDF]

open access: gold, 2010
We have evaluated in vitro the potency of 23 oximes to reactivate human erythrocyte acetylcholinesterase (AChE) and plasma butyrylcholinesterase (BChE) inhibited by racemic leptophos-oxon (O-[4-bromo-2,5-dichlorophenyl]-O-methyl phenyl-phosphonate), a ...

In-silico drug repositioning studies of Candida albicans Nitrogen permease reactivator 1 (Npr1) kinase [PDF]

open access: yesScientific Reports
Npr1 is an essential protein in C. albicans, maintains ion homeostasis and nutrient transportation at cell membrane, and regulates the activity of ammonium transporter protein Mep2.

Tannic acid reactivates HIV-1 latency by mediating CBX4 degradation [PDF]

open access: yesJournal of Virology
HIV-1 can integrate viral DNA into host cell chromosomes and establish a long-term stable latent viral reservoir, a major obstacle in curing HIV-1 infection. The reactivation of latent proviruses with latency-reversing agents (LRAs) is a prerequisite for

Structure of HI-6*sarin-acetylcholinesterase determined by X-ray crystallography and molecular dynamics simulation: reactivator mechanism and design. [PDF]

open access: yesPLoS ONE, 2009
Organophosphonates such as isopropyl metylphosphonofluoridate (sarin) are extremely toxic as they phosphonylate the catalytic serine residue of acetylcholinesterase (AChE), an enzyme essential to humans and other species.
