Synthesis, in vitro screening and molecular docking of isoquinolinium-5-carbaldoximes as acetylcholinesterase and butyrylcholinesterase reactivators

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2020
The series of symmetrical and unsymmetrical isoquinolinium-5-carbaldoximes was designed and prepared for cholinesterase reactivation purposes. The novel compounds were evaluated for intrinsic acetylcholinesterase (AChE) or butyrylcholinesterase (BChE ...

Ambident Reactivity in the Phenyl + NO Radical Recombination

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT The recombination reaction of nitric oxide (NO) with radicals via its oxygen atom, rather than the more common nitrogen site, offers an intriguing pathway to the formation of oxynitrenes. The photochemical isomerization of nitroso compounds into their corresponding oxynitrenes may involve such a step.

The Design, Synthesis, and Antioxidant Activity of Amphiphilic Oximes and Amidoximes

open access: yesActa Chimica Slovenica, 2013
New amphiphilic benzamidoxime, benzoxime, and aliphatic oxime derivatives of glycolipid mimetics were synthesized. The total antioxidant capacity of these amphiphilic derivatives was evaluated using DPPH assay.

An Analytical Method for Detecting Toxic Metal Cations Using Cyclotriveratrylene Derivative Capped Gold Nanoparticles [PDF]

open access: yes, 2015
Cyclotriveratrylene-oxime (CTV-oxime) derivatives that terminate with a dithiolate linker were synthesized enabling the supramolecular scaffold to adhere to gold nanoparticles (AuNPs) with the bowl-shaped cavity of the CTV scaffold exposed for ...

Electrochemical Dehydration of Carboxamides to Their Nitriles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Electrochemical dehydration of carboxamides to nitriles is achieved using thiocyanate‐mediated activation, avoiding stoichiometric reagents. In an undivided cell at ambient conditions, 18 aromatic and aliphatic substrates give good‐to‐excellent yields (up to 84%) with functional‐group tolerance. Cyclic voltammetry supports an EC‐type‐mediated oxidation.

Novel Bisquaternary Oximes—Reactivation of Acetylcholinesterase and Butyrylcholinesterase Inhibited by Paraoxon

open access: yesMolecules, 2009
Four novel bisquaternary aldoxime cholinesterase reactivators differing in their chemical structure were prepared. Afterwards, their biological activity was evaluated for their ability to reactivate acetylcholinesterase (AChE; EC 3.1.1.7) and ...

Vitamin A Status of Women and Children in Yaoundé and Douala, Cameroon, is Unchanged One Year after Initiation of a National Vitamin A Oil Fortification Program. [PDF]

open access: yes, 2017
Vitamin A (VA) fortification of cooking oil is considered a cost-effective strategy for increasing VA status, but few large-scale programs have been evaluated. We conducted representative surveys in Yaoundé and Douala, Cameroon, 2 years before and 1 year
