Competitive extraction of some bases by carbollyl-cobaltate anion from water into chloroform

The bis[undecahydro-7,8-dicarbaundecaborato(2-)]cobaltate(1-) (X-) has been used for complementary study of its ionic associates with some cations of organic bases and quaternary salts. For the optimization of present analytical methods, quinuclidin-3-yl hydroxy(diphenyl)acetate, 1-(1-phenylcyclohexyl)piperidine, dibenzo[b,f][1,4]oxazepine and cocaine, were studied by competitive extraction method. X- labelled with Co-60 was used as carrier anion, triphenylmethane and azo dyes as competitive anions, The aqueous phase was 0.1 and 0.01 M HCl, the organic phase was chloroform. A comparison was made with earlier results obtained by extraction spectrophotometry.

New synthesized oximes active in nerve agents’ hazards

Object: The aim of the study is to select the most active new imidazolium-quinuclidinumoxime, from some similar chemical compounds synthesized in our chemistry department, with sufficient efficacy to decrease the acute toxicity of neurotoxic organophosphates known as nerve agents. Method: The experimental study consist in vivo testing the antidotal efficacy of obidoxime and of selected imidazolium oximes synthesized in our chemistry department. Each oxime was included, by equimolar replacing the obidoxime, in an antidotal formula, which also contains atropine. The above mentioned formula containing atropine and obidoxime was used as reference. The protective ratio, defined as the ratio between the lethal median dose of the poisoned and treated study group and the median lethal dose (LD50) of the poisoned and untreated study groups was one of the used parameters in order to select a new active chemical structure in counteracting the neurotoxic organophosphorus compounds acute toxicity. Another studied parameter was the erythrocyte acetylcholinesterase value measured in whole blood 24 hours after exposure. Results: The protective ratio against an organophosphorus compound were the follow: obidoxime chloride: 2; 1,3dimethyl-2-hydroxyethyl-imidazolyliodide: 1,75;3-oxime-[3-(2-hidroxyimino-methyl-1-imidazolyl-)-2oxapropyl] quinuclidin-dichl-oride: 2,5; 1-methyl-quinuclidin-3-iodide: 1,5. The erythrocyte acetycholinesterase main values were the following: the unpoisoned and untreated study group: 3,45 +/- 0,13mmol/dl; the poisoned and untreated study group: 0,89 +/- 0,09 mmol/dl; the poisoned and 3oxime-[3-(2-hidroxyimino-methyl-1-imidazolyl-)-2oxapropyl]quinuclidindichloride treated study group: 2,89 +/- 0,11 mmol/dl; the poisoned and obidoxime treated study group: 2,53 +/- 0,15 mmol/dl. Conclusions: 3-oxime-[3-(2-hidroxyimino-methyl-1-imidazolyl-)-2oxapropyl] quinuclidindichloride synthesized in our chemistry department, has shown a better protective ratio and a more prolonged surviving time than the reference (obidoxime). It has shown the best AChE reactivation of all the synthetized compounds. This compound can be a cheap and good option for replacing obidoxime in the antidotal formula active in nerve agent exposure.

Interactions of chiral quinuclidin-3-yl benzoates with butyrylcholinesterase: kinetic study and docking simulations

Both enantiomers of quinuclidin-3-yl benzoate (RQBz and SQBz) were synthesized in order to examine the stereoselectivity of the hydrolysis of these esters catalyzed by horse serum butyrylcholinesterase (BChE). The hydrolysis of benzoylcholine (BzCh) was also studied in order to determine the influence of the alcohol part of the esters upon the kinetics. The k(cat) value for the substrates decreased in order BzCh > RQBz (4-fold slower) much greater than SQBz (76-fold slower reaction). K-M values determined for quinuclidinium substrates revealed that the binding affinity of RQBz (0.28 mm) is approximately 2-fold lower than that of SQBz (0.13 mM) towards BChE. From the ratio of the enantiomeric k(cat)/K-M values, an enantiomeric excess of 78% was calculated, indicating that the resolution of racemic quinuclidin-3-yl benzoate can be achieved by hydrolysis with BChE. The orientations of all the studied benzoate esters and butyrylcholine (BuCh) in the active site of human BChE were proposed by flexible ligand docking with AutoDock 3.0. Analyses of the Michaelis complexes obtained revealed that there are numerous similar close contacts in the active site. The main difference in binding of quinuclidinium and choline esters was found in the ammonium electrostatic region which includes cation-pi interaction of the ammonium moiety of substrates with the indole ring of Trp(84). The important cation-pi interaction with Trp(84) was lowest in the case of the S-enantiomer of QBz, which might be the main explanation for the slowest rate of hydrolysis of that compound.
