Résumé :
We explore the detection of paraoxon, a model compound for nonvolatile organophosphate nerve agents such as VX. The detection utilizes europium complexes with 1,10 phenanthroline and thenoyltrifluoroacetone as sensitizing ligands. Both europium luminescence quenching and luminescence enhancement modalities are involved in the detection, which is simple, rapid, and sensitive. It is adaptable as well to the more volatile fluorophosphate nerve agents. It involves nothing more than visual luminescence observation under sample illumination by an ordinary hand-held ultraviolet lamp.

Through reduction of coordinated P– Cl ligands in selected complexes II and III complexes bearing PH3, P(C6H5)H2 and P(C6H5)2H ligands are available. With anhydrous KF in acetonitrile solution in the presence of dibenzo-18-crown-6, the coordinated P– Cl ligands in selected complexes II and HIII undergo Cl/F-exchange with formation of related complexes with P(CH3)ClF, P(CH3)F2, PF2Cl and PF3 ligands.

Résumé :
Post-translational modifications were recently shown to be responsible for the short circulatory mean residence time (MRT) of recombinant human acetylcholinesterase (rHuAChE) [Kronman, Velan, Marcus, Ordentlich, Reuveny and Shafferman (1995) Biochem. J. 311, 959–967; Chitlaru, Kronman, Zeevi, Kam, Harel, Ordentlich, Velan and Shafferman (1998) Biochem. J. 336, 647–658; Chitlaru, Kronman, Velan and Shafferman (2001) Biochem. J. 354, 613–625], which is one of the major obstacles to the fulfilment of its therapeutic potential as a bioscavenger. In the present study we demonstrate that the MRT of rHuAChE can be significantly increased by the controlled attachment of polyethylene glycol (PEG) side chains to lysine residues. Attachment of as many as four PEG molecules to monomeric rHuAChE had minimal effects, if any, on either the catalytic activity (Km = 0.09mM and kcat = 3.9×105min−1) or the reactivity of the modified enzyme towards active-centre inhibitors, such as edrophonium and di-isopropyl fluorophosphate, or to peripheral-site ligands, such as propidium, BW284C51 and even the bulky snake-venom toxin fasciculin-II. The increase in MRT of the PEG-modified monomeric enzyme is linearly dependent, in the tested range, on the number of attached PEG molecules, as well as on their size. It appears that even low level PEG-conjugation can overcome the deleterious effect of under-sialylation on the pharmacokinetic performance of rHuAChE. At the highest tested ratio of attached PEG-20000/rHuAChE (4:1), an MRT of over 2100min was attained, a value unmatched by any other known form of recombinant or native serum-derived AChE reported to date.

DELGADO, CALVO FUENCISLA. « Some advances in low valent phosphorus chemistry : fluorophosphines, naked polyphosphorus compounds and metal phosphide nanoparticles ». Doctoral thesis, 2016. http://hdl.handle.net/2158/1019937.

Résumé :
Phosphorus chemistry is a very broad field with a great range of applications. The goals of this Ph.D. thesis are related to different aspects of low-valent phosphorus chemistry: going from the synthesis of fluorophosphine ligands through a “green” and innovative pathway, to the activation and functionalization of elemental white phosphorus in the presence of late transition metals, and, finally, to the not yet explored synthesis of ruthenium phosphide nanoparticles starting from white phosphorus. In Chapter 1, different points related to the phosphorus chemistry are mentioned. The opening section reports a general description of the element phosphorus and its allotropic modifications before taking into detailed consideration the reactivity of white phosphorus, emphasizing on the production of organophosphorus compounds through catalytic processes involving the activation of P4 mediated by transition metal complexes. The second section depicts a brief introduction about the importance of phosphine ligands in catalysis, particularly giving attention to the role of fluorophosphine ligands. Finally, the last section deals with the synthesis of metal phosphides nanoparticles, which are of great interest on diverse fields, particularly in catalysis, aiming at P4-derived metal phosphide nanoparticles. Chapter 2 describes the study of the transformation of phosphorous oxyacids, such as PhPO(OH)H, H3PO3, H3PO2, into the corresponding fluorophosphines mediated by [CpRu(PPh3)2Cl] under mild reaction conditions using a soft deoxyfluorinating agent, commercially available as XtalFluor-E. The reaction is selective, proceeds with high yields and can be extended to a wide range of phosphorous oxyacids once coordinated to the ruthenium fragment {CpRu(PPh3)2}+ as their hydroxyphosphine tautomer. Deoxyfluorination of phenylphosphinic acid was also mediated by [CpRRu(CH3CN)3]PF6, where CpR: Cp = C5H5, Cp* = C5Me5, and {η6-(p-cymene)Ru(µ-Cl)Cl}2. On chapter 3, the coordination chemistry of white phosphorus towards a 16 electron ruthenium organometallic complex [Cp*RuPCy3X], where Cp* = C5Me5, X = Cl, Br, I is described. The different electronegativity and steric bulk in the series of halogens changes the reactivity with white phosphorus. Migration of the halogen from ruthenium to the P4 moiety was observed, in the case of chloride and bromide, obtaining bimetallic complexes bearing unexpected P4X2 (X = Cl, Br) moiety as bridging ligands. In the case of iodide, a completely different structure is proposed, containing the not yet previously reported P4I ligand as a bridging moiety between two Ru(II) centers. Chapter 4 deals with the synthesis and characterization of ruthenium phosphide nanoparticles using white phosphorus as P-source. The novelty introduced is the use of white phosphorus as phosphorus source to react with previously prepared ruthenium nanoparticles. A preliminary catalytic study on hydrogenation of phenylacetylene under mild conditions shows very good catalytic activity and selectivity towards the fully hydrogenated product, ethylbenzene.
