Uranium pollution involves high toxicity and radioactivity and, therefore, constitutes a grave threat to human health and the environment. Chelation is an effective method for sequestering uranium. It is well known that chelators based on oxime groups are able to complex uranyl cations efficiently. To this end, various bis(amidoxime)s were synthesized by reaction of hydroxylamine with the corresponding dinitriles. In these compounds the amidoximes are separated by chains of various lengths, some including a heterocycle (pyridine or 1,3,5-triazine). The abilities of these bis(amidoxime)s to complex uranyl cation in water were evaluated by determining their affinity constants and thermodynamic parameters by means of Isothermal Titration Calorimetry (ITC). DFT calculations were also performed, to determine the optimum structures of the complexes formed between uranyl cations and the oximate groups. A tetrakis(amidoxime), also synthesized in this work, shows good affinity for uranium, and a single molecule is able chelate several uranyl cations. These results are of importance for the remediation of uranium-polluted wastewaters, and open up several perspectives for the design and synthesis of new amidoxime compounds.

Protein conformational fluctuations are critical for biological functions, although the relationship between protein motion and function has yet to be fully explored. By a thorough bioinformatics analysis of cholinesterases (ChEs), we identified specific hot spots, responsible for protein fluctuations and functions, and those active-site residues that play a role in modulating the cooperative network among the key substructures. This drew the optimization of our design strategy to discover potent and reversible inhibitors of human acetylcholinesterase and butyrylcholinesterase (hAChE and hBuChE) that selectively interact with specific protein substructures. Accordingly, two tricyclic moieties differently spaced by functionalized linkers were investigated as molecular yardsticks to probe the finest interactions with specific hot spots in the hChE gorge. A number of SAR trends were identified, and the multisite inhibitors 3a and 3d were found to be the most potent inhibitors of hBuChE and hAChE known to date.

Studies on the mechanism of chelate degradation in iron-based, liquid redox H2S removal processes

Available data on the oxidation of nitrilotriacetic acid (NTA), ethylenedinitrilotetraacetic acid (EDTA), N-hydroxyethylethylenediaminetriacetic acid (HEDTA), and other aminopolycarboxylate chelating agents are reviewed and the intermediates and products of the oxidative degradation of each chelating agent are described and compared.The oxidation of these chelating agents occurs during the reoxidation of the ferrous chelatre to the ferric chelate, during which a Fenton type side reaction occurs in which hydrogen peroxides is formed and which in turn generates the hydroxyl radical by reaction with ferrous ion.The site of oxidative attack by the hydroxyl radical on these ligands seems to be the -CH2- groups α to the carboxylate groups, as well as the -CH2- groups in the ethylene bridges between the nitrogens.The evidence for the implication of the hydroxyl radical as the active oxidant is discussed, and the use of phenyl-tert-butylnitrone (PBN) as the trapping agent for the hydroxyl radical is described.The use of chelating agents as Fe3+/Fe2+ redox catalysts for the oxidation of H2S to sulfur that are less reactive toward the hydroxyl radical is recommended. Key words: chelate degradation, H2S oxidation, nitrilotriacetic acid (NTA), ethylenedinitrilotetraacetic acid (EDTA), N-hydroxyethylethylenediaminetriacetic acid (HEDTA).
