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.

The orientations of chiral quinuclidin-3-ol esters and benzoylcholine in the active site of horse butyrylcholinesterase have been investigated by flexible ligand docking. Change of the esters’ acyl moiety as well as the substituent at the quinuclidinium nitrogen atom affected the activity and stereoselectivity of the biotransformations. Analysis of interactions in the active site revealed the most important binding patterns for enantiomers, which define their reactivity. Calculated Gibbs energies of binding obtained by molecular docking simulations were well correlated to the experimentally determined binding affinities of the investigated chiral esters.

Effects of (R)-N-(quinuclidin-3-yl)-2-(1-methyl-1H-indol-3-yl)-2-oxo-acetamide (RS-056812-198) on 5-HT3 receptors have been investigated in whole-cell voltage-clamped N1E-115 mouse neuroblastoma cells and on 5-HT3 receptors composed of either long (5-HT(3)R-A(L)) or short (5-HT(3)R-A(S)) subunits expressed in Xenopus laevis oocytes. In N1E-115 cells RS-056812-198 evokes small transient inward currents, which are completely and reversibly inhibited by the selective 5-HT3 receptor antagonist MDL 72222 and cross-desensitizes with the 5-hydroxytryptamine (5-HT)-evoked current. The concentration-effect curve of RS-056812-198 yields an EC(50) of 18 nM and a maximum amplitude of 15% of the maximum 5-HT-evoked current. In contrast to its effects on N1E-115 cells, RS-056812-198 does not evoke an ion current on cloned 5-HT3 receptors expressed in Xenopus oocytes, but acts as an antagonist. For 5-HT(3)R-A(L) receptors, the IC50 of RS-056812-198 is 0.4 nM. The results show that (1) RS-056812-198 is a high-affinity partial agonist on 5-HT3 receptors in N1E-115 cells, thus providing a valuable tool to study agonist-receptor interaction in more detail; (2) 5-HT3 receptors in N1E-115 cells differ from the homo-oligomeric 5-HT3 receptors expressed in Xenopus oocytes. Whether the difference is caused by differences in protein processing in the two preparations or by expression of additional, yet unidentified subunits in N1E-115 cells and consequent formation of hetero-oligomeric 5-HT3 receptors remains to be determined.
