Treatment of Cu2(OAc)4¡¤2H2O with 2,2?-dipyridylamine (dpa) in 1:2 molar ratio in MeCN-H2O results neutral [Cu(OAc)2(dpa)]¡¤2H2O (1) which on subsequent treatment with 1 equiv of NaBF4 affords [Cu(OAc)(dpa)2]BF4 (2). The complexes are characterized using microanalytical, spectroscopic, magnetic, thermal, electrochemical, and other physicochemical results. Electrochemical electron transfer study of 1 and 2 in MeCN solutions show a reductive response presumably due to copper(II)-copper(I) couple. Thermal study (TG-DTA) of 1 reveals a weight loss of 9.21% at 70-85 K corresponding to two crystalline water molecules. Structures of 1 and 2 are solved by X-ray diffraction study. Compound 1 adopts a distorted octahedral CuN2O4 environment coordinated through two N atoms of dpa and four O atoms of two chelating acetates with elongated axial bonds. In 2, copper(II) is ligated by four N atoms of two dpa units and two O atoms of an acetate in chelating fashion resulting a cationic core of [Cu(OAc)(dpa)2]+. Crystal packings show that mononuclear units of 1 self-assemble through cooperative hydrogen bonds and pi…pi interaction and of 2, through hydrogen bonds along with C-H…pi interaction leading to 2D sheets. Both the complexes show high-energy intraligand 1(pi…pi*) fluorescence and intraligand 3(pi…pi*) phosphorescence in glassy solutions (DMF at 77 K).

Hypochlorous acid and its acid-base counterpart, hypochlorite ions, produced under inflammatory conditions, may produce chloramides of glycosaminoglycans, these being significant components of the extracellular matrix (ECM). This may occur through the binding of myeloperoxidase directly to the glycosaminoglycans. The N-Cl group in the chloramides is a potential selective target for both reducing and oxidizing radicals, leading possibly to more efficient and damaging fragmentation of these biopolymers relative to the parent glycosaminoglycans. In this study, the fast reaction techniques of pulse radiolysis and nanosecond laser flash photolysis have been used to generate both oxidizing and reducing radicals to react with the chloramides of hyaluronan (HACl) and heparin (HepCl). The strong reducing formate radicals and hydrated electrons were found to react rapidly with both HACl and HepCl with rate constants of 1-1.7 x 108 and 0.7-1.2 x 108 M-1 s-1 for formate radicals and 2.2 x 109 and 7.2 x 10 8 M-1 s-1 for hydrated electrons, respectively. The spectral characteristics of the products of these reactions were identical and were consistent with initial attack at the N-Cl groups, followed by elimination of chloride ions to produce nitrogen-centered radicals, which rearrange subsequently and rapidly to produce C-2 radicals on the glucosamine moiety, supporting an earlier EPR study by M.D. Rees et al. (J. Am. Chem. Soc. 125: 13719-13733; 2003). The oxidizing hydroxyl radicals also reacted rapidly with HACl and HepCl with rate constants of 2.2 x 108 and 1.6 x 108 M-1 s-1, with no evidence from these data for any degree of selective attack on the N-Cl group relative to the N-H groups and other sites of attack. The carbonate anion radicals were much slower with HACl and HepCl than hydroxyl radicals (1.0 x 105 and 8.0 x 10 4 M-1 s-1, respectively) but significantly faster than with the parent molecules (3.5 x 104 and 5.0 x 10 4 M-1 s-1, respectively). These findings suggest that these potential in vivo radicals may react in a site-specific manner with the N-Cl group in the glycosaminoglycan chloramides of the ECM, possibly to produce more efficient fragmentation. This is the first study therefore to conclusively demonstrate that reducing radicals react rapidly with glycosaminoglycan chloramides in a site-specific attack at the N-Cl group, probably to produce a 100% efficient biopolymer fragmentation process. Although less reactive, carbonate radicals, which may be produced in vivo via reactions of peroxynitrite with serum levels of carbon dioxide, also appear to react in a highly site-specific manner at the N-Cl group. It is not yet known if such site-specific attacks by this important in vivo species lead to a more efficient fragmentation of the biopolymers than would be expected for attack by the stronger oxidizing species, the hydroxyl radical. It is clear, however, that the N-Cl group formed under inflammatory conditions in the extracellular matrix does present a more likely target for both reactive oxygen species and reducing species than the N-H groups in the parent glycosaminoglycans.
