Abstract
The structure of 2,5-dicarboxy-1-methylpyridinium inner salt (1), has been studied by X-ray diffraction, B3LYP/6-311G(d,p) calculations, FTIR, Raman and NMR spectroscopy. The molecules are linked by short intermolecular and asymmetric O-H⋯O hydrogen bonds of 2.486(2)Å between carboxyl and carboxylate groups of neighboring molecules into infinite chains. The hydrogen bonds in the molecules optimized by the B3LYP/6-311G(d,p) approach in trimer (2) and dimer (3) are slightly longer than in the crystal. The FTIR spectrum of the investigated inner salt is dominated by a broad and intense absorption in the 1500-800 cm(-1) region attributed to the ν(as)(OHO) and γ(OHO) vibrations of the strong hydrogen bond. In the Raman spectrum the broad absorption is absent. Linear correlations, δ(exp)=a+b σ(calc) between the experimental (1)H and (13)C NMR chemical shifts (δ(exp)) of the investigated inner salt in D2O and the calculated magnetic isotropic shielding constants (σ(calc)) for the optimized monomer (4a) solvated in water are reported. The pKa value for 1 of 2.31±0.02 was determined by the potentiometric titration.

Abstract
In this study, four mononuclear M(II)-pyridine-2,5-dicarboxylate (M = Co(II), Ni(II), Cu(II) and Zn(II) complexes with pyridine-2,5-dicarboxylic acid or isocinchomeronic acid, 1,10-phenanthroline (phen), [Co(Hpydc)(2)(phen)]·H(2)O (1), [Ni(pydc)(phen)(2)]·6.5H(2)O (2) [Cu(pydc)(phen)(H(2)O)(2)] (3) and [Zn(pydc)(phen)(H(2)O)(2)]·H(2)O (4) have been synthesized. Elemental, thermal and mass analyses, molar conductance, magnetic susceptibilities, IR and UV/vis spectroscopic studies have been performed to characterize the complexes. Subsequently, these ligands and complexes were tested for antimicrobial activity by disc diffusion method on Gram positive, negative bacteria and yeast. In addition, cytotoxic activity tests were performed on rat glioma (C6) cells by MTT viability assay for 24 and 48 h. Antimicrobial activity results demonstrated that when compared to the standard antibiotics, phen displayed the most effective antimicrobial effect. The effect of synthesized complexes was close to phen or less. Cytotoxic activity results showed that IC(50) value of phen was determined as 31 μM for 48 h. (1) and (2) compared to the alone ligand had less toxic activity. IC(50) values of (3) for 24 and 48 h treatments were 2.5 and 0.6 μM, respectively. IC(50) value of (4) for 48 h was 15 μM. In conclusion, phen, (3) and (4) may be useful as antibacterial and antiproliferative agents in the future.

Abstract
2-Oxoglutarate (2OG) dependent oxygenases are ubiquitous iron enzymes that couple substrate oxidation to the conversion of 2OG to succinate and carbon dioxide. In humans their roles include collagen biosynthesis, fatty acid metabolism, DNA repair, RNA and chromatin modifications, and hypoxic sensing. Commercial applications of 2OG oxygenase inhibitors began with plant growth retardants, and now extend to a clinically used pharmaceutical compound for cardioprotection. Several 2OG oxygenases are now being targeted for therapeutic intervention for diseases including anaemia, inflammation and cancer. In this critical review, we describe studies on the inhibition of 2OG oxygenases, focusing on small molecules, and discuss the potential of 2OG oxygenases as therapeutic targets (295 references).

Abstract
Within the mass spectrometric study of bisubstituted isoquinolines that possess great potential as prolylhydroxylase inhibitor drug candidates (e.g., FG-2216), unusually favored gas-phase formations of carboxylic acids after collisional activation were observed. The protonated molecule of [(1-chloro-4-hydroxy-isoquinoline-3-carbonyl)-amino]-acetic acid was dissociated, yielding the 1-chloro-4-hydroxy-isoquinoline-3-carboxylic acid methyleneamide cation. Subsequent dissociation caused the nominal elimination of 11 u that resulted from the loss of HCN and concomitant addition of oxygen to the product ion, which formed the protonated 1-chloro-4-hydroxy-isoquinoline-3-carboxylic acid. The preference of this structure under mass spectrometric conditions was substantiated by tandem mass spectrometry analyses using the corresponding methyl ester (1-chloro-4-hydroxy-isoquinoline-3-carboxylic acid methyl ester) that eliminated methylene (-14 u) upon collisional activation. Moreover, the major product ion of 1-chloro-4-hydroxy-isoquinoline-3-carboxylic acid, which resulted from the loss of water in MS3 experiments, restored the precursor ion structure by re-addition of H2O. Evidences for these phenomena were obtained by chemical synthesis of proposed gas-phase intermediates, H/D exchange experiments, high-resolution/high accuracy mass spectrometry at MSn level, and "ping-pong" analyses (MS7, in which the precursor ion was dissociated and the respective product ion isolated to regenerate the precursor ion for repeated dissociation. Based on these results, dissociation pathways for [(1-chloro-4-hydroxy-isoquinoline-3-carbonyl)-amino]-acetic acid were suggested that can be further utilized for the characterization of structurally related compounds or metabolic products in clinical, forensic, or doping control analysis.

Abstract
The new compound sodium 5-(1-dodecylaminocarbonyl) picolinate (NaDPA) has been prepared and found to have the unusual surfactant property of forming stable water-oil (w/o) emulsions in the presence of water and a variety of organic liquids. A study of droplet size (diameters=0.1-1.0 mm) as a function of the amount of surfactant used shows that a near constant coverage of surfactant molecules exists at the water-oil interface and that the interface is made up of multiple layers. The structure of NaDPA, with its multiple hydrogen-bonding possibilities, probably contributes to the observed stability of the emulsions. The emulsions are made up of droplets that are stable for months and can be filled with dyes, buffers, and solutions of high ionic strength.

Abstract
Prolyl 4-hydroxylases catalyze the formation of 4-hydroxyproline in collagens and other proteins with an appropriate collagen-like stretch of amino acid residues. The enzyme requires Fe(II), 2-oxoglutarate, molecular oxygen, and ascorbate. This review concentrates on recent progress toward understanding the detailed mechanism of 4-hydroxylase action, including: (a) occurrence and function of the enzyme in animals; (b) general molecular properties; (c) intracellular sites of hydroxylation; (d) peptide substrates and mechanistic roles of the cosubstrates; (e) insights into the development of antifibrotic drugs; (f) studies of the enzyme's subunits and their catalytic function; and (g) mutations that lead to Ehlers-Danlos Syndrome. An account of the regulation of collagen hydroxylase activities is also provided.

Abstract
Prolyl 4-hydroxylases (EC 1.14,11.2) catalyze the formation of 4-hydroxyproline in collagens and other proteins with collagen-like sequences. The vertebrate type I and type II enzymes are [alpha (I)]2 beta 2 and [alpha (II)]2 beta 2 tetramers, respectively, whereas the enzyme from the nematode Caenorhabditis elegans is an alpha beta dimer. The type I enzyme is the major form in most but not all vertebrate tissues. The catalytic properties of the various enzyme forms are highly similar, but there are distinct, although small, differences in K(m) values for various peptide substrates between the enzyme forms and major differences in Ki values for the competitive inhibitor, poly(L-proline). Prolyl 4-hydroxylase requires Fe2+, 2-oxoglutarate, O2 and ascorbate. Kinetic studies and theoretical considerations have led to elucidation of the reaction mechanism, and recent extensive site-directed mutagenesis studies have identified five critical residues at the cosubstrate binding sites. A number of compounds have been characterized that inhibit it competitively with respect to some of the cosubstrates, and three groups of suicide inactivators have also been identified. The beta subunit in all forms of prolyl 4-hydroxylase is identical to protein disulfide isomerase (PDI), a multifunctional polypeptide that also serves as a subunit in the microsomal triglyceride transfer protein, as a chaperone-like polypeptide that probably assists folding of a number of newly synthesized proteins, and in several other functions. The main role of the PDI polypeptide as a protein subunit is probably related to its chaperone function. Recent expression studies of recombinant human prolyl 4-hydroxylase subunits in a yeast have indicated that the formation of a stable enzyme tetramer in vivo requires coexpression of collagen polypeptide chains.
