The direct visible light-mediated C-H alkylation of heteroarenes using aliphatic carboxylic acids is reported. This mild method proceeds at low catalyst loadings (0.5 mol %) and has a high functional group tolerance and a broad substrate scope. Notably, functionalization of (iso)quinoline, pyridine, phthalazine, benzothiazole, and other heterocyclic derivatives with both cyclic and acyclic primary, secondary, and tertiary carboxylic acids as well as amino and fatty acids proceeded under the standard conditions at room temperature. This protocol enables the rapid conversion of abundant feedstock materials into medically relevant drug-like moieties.

Four new complex compounds of bis(phthalazine-1-hydrazone)-2,6-diacetylpyridine (Hz(2)DAP) ligand with Ni-II, Co-III, Cu-II and Zn-II metal centres were synthesised and characterised by single-crystal X-ray diffraction and IR spectral data. The antimicrobial activity of Hz(2)DAP and the obtained complexes [Co(Hz(2)DAP-H)Cl-2]center dot MeOH, [Ni(Hz(2)DAP-H)]Cl center dot MeOH, [Cu(Hz(2)DAP-H)Cl] and [Zn(Hz(2)DAP-2H)]center dot H2O were tested in vitro against selected Gram(-) and Gram(+) bacterial strains and fungi. The antimicrobial activity of the ligand is negligible, while its complexes with Ni-II, Co-III and Cu-II show considerable activity against Escherichia coli, Staphylococcus aureus and Micrococcus lysodeikticus. On the contrary, [Zn(Hz(2)DAP-2H)]center dot H2O promotes the growth of Candida albicans, while its antibacterial activity is negligible. On the basis of thermal data and those from coupled TG/MS measurements the decomposition mechanisms were determined and evaluated. (C) 2014 Elsevier Ltd. All rights reserved.

In a document, author is Barr, John T., introduce the new discover, Application of 7507-86-0.

The goal of this study was to provide a reasonable assessment of how probe substrate selection may impact the results of in vitro aldehyde oxidase (AO) inhibition experiments. Here, we used a previously studied set of seven known AO inhibitors to probe the inhibition profile of a pharmacologically relevant substrate N-[(2-dimethylamino)ethyl]acridine-4-carboxamide (DACA). DACA oxidation in human liver cytosol was characterized with a measured V-max of 2.3 +/- 0.08 nmol product . min(-1) . mg(-1) and a K-m of 6.3 +/- 6 0.8 mu M. The K-ii and K-is values describing the inhibition of DACA oxidation by the panel of seven inhibitors were tabulated and compared with previous findings with phthalazine as the substrate. In every case, the inhibition profile shifted to a much less uncompetitive mode of inhibition for DACA relative to phthalazine. With the exception of one inhibitor, raloxifene, this change in inhibition profile seems to be a result of a decrease in the uncompetitive mode of inhibition (an affected K-ii value), whereas the competitive mode (K-is) seems to be relatively consistent between substrates. Raloxifene was found to inhibit competitively when using DACA as a probe, and a previous report showed that raloxifene inhibited uncompetitively with other substrates. The relevance of these data to the mechanistic understanding of aldehyde oxidase inhibition and potential implications on drug-drug interactions is discussed. Overall, it appears that the choice in substrate may be critical when conducting mechanistic inhibition or in vitro drug-drug interactions prediction studies with AO

A tridentate Schiff base ligand, (E)-3-((2-hydroxy-3-methoxybenzylidene)amino)-2-methylquinazolin-4(3H)-one [HL], and its mixed-ligand Ni(II) complex [Ni(L)(imi)], were synthesized and fully characterized using elemental analysis, FT-IR, UV-Vis and (HNMR)-H-1 spectroscopy techniques. The structure of the synthesized ligand and complex was determined with single crystal X-ray diffraction method. In the complex, a square planner geometry was observed around the Ni(II) central atom coordinated with the donor atoms of the Schiff base ligand and one nitrogen of imidazole group. In addition, the catalytic activity of the complex on the three-component condensation of hydrazine hydrate with phthalic anhydride and dimedone to obtain 2H-indazolo[2,1-b]phthalazine-triones was investigated. Furthermore, in-vitro antimicrobial studies were performed that indicated the great antibacterial activities of the Ni(II) complex against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus cereus bacteria.
