Functionalised oximes : emergent precursors for carbon-, nitrogen- and oxygen-centred radicals [PDF]

open access: yes, 2016
The author thanks EaStCHEM for financial support.Oxime derivatives are easily made, are non-hazardous and have long shelf lives. They contain weak N–O bonds that undergo homolytic scission, on appropriate thermal or photochemical stimulus, to initially ...

Synthesis of Trifluoromethylated Monoterpene Amino Alcohols

open access: yesMolecules, 2022
For the first time, monoterpene trifluoromethylated β-hydroxy-benzyl-O-oximes were synthesized in 81–95% yields by nucleophilic addition of the Ruppert–Prakash reagent (TMSCF3) to the corresponding β-keto-benzyl-O-oximes based on (+)-nopinone ...

A Comparison of the Therapeutic Efficacy of Conventional and Modern Oximes Against Supralethal Doses of Highly Toxic Organophosphates in Mice

open access: yesActa Medica, 1998
1. The therapeutic efficacy of various oximes (pralidoxime, obidoxime, methoxime, HI-6, HLö-7, BI-6) against supralethal nerve agent poisoning (soman, sarin, cyclosin) in mice was tested. 2. New oxime BI-6, synthesized in our laboratory, is significantly

Conversion of Natural Aldehydes from Eucalyptus citriodora, Cymbopogon citratus, and Lippia multiflora into Oximes: GC-MS and FT-IR Analysis †

open access: yesMolecules, 2009
Three carbonyl-containing extracts of essential oils from Eucalyptus citriodora (Myrtaceae), Cymbopogon citratus (Gramineae) and Lippia multiflora (Verbenaceae) were used for the preparation of oximes.

Comparison of pKa values for oxy-enzymase derivatives derived from 3-acetyl and 4-acetyl-3 serotonin by using glass pole [PDF]

open access: yesمجلة التربية والعلم, 2014
The study includes the preparation of four syn and anti oximes derived from mother ketones, namely 3-acetyl and 4-acetyl pyridine by standard method. The structures of these oximes were confirmed by using UV and IR spectra, melting points and specific ...

Preparing a rat brain tissue samples for acetylcholinesterase activity measurement: The MM method [PDF]

open access: yesScripta Medica, 2021
Background/Aim: Organophosphorus compounds (OP) bind to acetylcholinesterase (AChE) causing an irreversible inhibition of the enzyme. When doing in vivo studies of OP intoxication, to precisely measure AChE activity in the brain tissue it is necessary to
