Synthesis and Research of Reactivation of Phosphorylated Cholinesterase by Quaternary Pyridinium-aldoxime Salts
The interaction of pyridine-4(-3,-2)aldoxime has been studied whit 3-bromo-N,N,N-trialkyl-2oxo(-hydroxyimino)-1-propanaminium bromide. The structure of all synthesized compounds was determined by elemental analysis as well as by physical and chemical methods. All synthesized compounds were tested for reactivation of phosphorylated acetylcholinesterase. Using fragments of the molecules (an oxime...
متن کاملThermolysis of pyridinium perchlorate salts
Three perchlorate salts of pyridine have been prepared and characterized by gravimetric and elemental analyses. Thermogravimetry (TG) and differential thermal analysis (DTA) have been carried out in static air, to examine the thermal decomposition process of these salts. Isothermal TG of these salts have been done to evaluate the kinetics of thermal decomposition in the temperature range 290-41...
متن کاملSynthesis of Quaternary Heterocyclic Salts
The microwave synthesis of twenty quaternary ammonium salts is described. The syntheses feature comparable yields to conventional synthetic methods reported in the current literature with reduced reaction times and the absence of solvent or minimal solvent.
متن کاملPyridinium Salts, Insertion Reaction, Oximes Pyridinium Salts with electron-withdrawing groups in the 3-position react with aliphatic ketoximes
Die Anlagerung von Nucleophilen an quartäre Pyridinium-Salze ist seit langem bekannt [2], ebenso die Beobachtung, daß Ringöffnungsund Umlagerungsreakt ionen sich anschließen können, gerade bei der Einwirkung von z.B. Hydroxidoder Alkoxid-Ionen und Aminen [3, 4]. Quartäre Salze von Pyridincarbaldoximen, die ausgeprägt hydrophile Eigenschaf ten haben, werden als Reaktivatoren bei In toxika t ion ...
متن کاملMicrowave synthesis of quaternary ammonium salts.
The microwave synthesis of several quaternary ammonium salts is described. The synthesis provides comparable or better yields than published methods with reduced reaction times and in the absence of solvent.
