The first crystal structure of a phenylcyanamide cobaltoxime (cobaloxime) complex is reported. This compound is trans-[Co((DO)(DOH)pn)(2,5-Cl2pcyd)2], and consits of an imine-oxime equatorial ligand ((DO)(DOH)pn) and two 2,5-dichlorophenylcyanamide ligands in axial positions. Crystals of trans- [Co((DO)(DOH)pn)(2,5-Cl2pcyd)2] were grown by ether diffusion into an acetonitrile solution of the co...

Alanine is widely employed for synthesizing polymers, pharmaceuticals, and agrochemicals. Electrocatalytic coupling of biomass molecules waste nitrate attractive the removal alanine production under ambient conditions. However, reaction efficiency relatively low due to activation stable substrates, two reactive intermediates remains challenging. Herein, we realize integrated tandem electrochemi...

oxime extractants 3-tert-butyl-2-hydroxy-5-methyl benzaldehyde oxime (hl1) and 3-tert-butyl-2-hydroxy-5-methoxy benzaldehyde oxime (hl2) were synthesized and characterized by conventional spectroscopic methods. suitable lipophilic nature of the prepared extractants allowed examining the ability of these molecules for extraction-separation of copper from its mixture with normally associated meta...

organophosphate (op) poisoning is one of the most common causes of poisoning in developing countries especially in southeastern asia. poisoning with phosphorus-containing organic chemicals or op compounds can be managed with antidotes like oximes which are potential reactivators of acetylcholinesterase (ache). the efficacy of oxime therapy in op poisoned patients mainly depends upon various fac...

The reactivating and therapeutic efficacy of two combinations of oximes (HI ‐6 + trimedoxime and HI ‐6 + K203) was compared with the effectiveness of antidotal treatment involving single oxime (hi ‐6, trimedoxime, K203) using in vivo methods. In vivo determined percentage of reactivation of cyclosarin ‐inhibited blood and tissue acetylcholinesterase in poisoned rats showed that the reactivating...

Quaternary salts of pyridoxal oxime have been synthesized by the quaternization of pyridoxal oxime with substituted phenacyl bromides using microwave heating. Microwave-assisted rapid synthesis was done both in solvent (acetone) and under solvent-free conditions. Good to excellent yields (58%-94%) were obtained in acetone in very short reaction times (3-5 min) as well as in the solvent-free pro...

The reactivation of nerve agent-inhibited acetylcholinesterase (AChE) by oxime is the most important step in the treatment of nerve agent poisoning. Since the evaluation of nerve agent antidotes cannot be conducted in humans, results from animal experiments are extrapolated to humans. Guinea pig is one of the animal models that is frequently used for conducting nerve agent antidote evaluations....

The conjugation of oligonucleotides with reporters is of great interest for improving their intrinsic properties or endowing new ones. In this context, we report herein a new procedure for the bis-labelling of oligonucleotides through oxime ligation (Click-O) and copper(I)-catalyzed alkyne-azide cycloaddition (Click-H). 5'-Azido and 3'-aldehyde precursors were incorporated into oligonucleotides...

Nitrite was formed from hydroxylamine and several oximes by intact cells and extracts of Pseudomonas aeruginosa. The activity was induced by the presence of oximes in the culture medium. Nitroalkanes were not intermediates in the conversion of acetaldoxime, acetone oxime, or butanone oxime to nitrite, since nitromethane inhibited the formation of nitrite from the nitro compounds but not from th...
