  Molecular design and the optimum synthetic route of the compounds with multi-pyrazole and its derivatives and the potential application in antibacterial agents

  摘要：

  Molecular design and efficient synthetic procedures have been developed for pyrazole and its derivatives with different linkers. In particular, twelve compounds with -I or -NO2 substituted groups on the pyrazole ring were synthesized for the first time. These compounds are characterized by element analysis, IR, HNMR, M.P. and X-ray diffraction. In addition, some compounds and corresponding complexes were also assayed in vitro for their ability to inhibit the growth of representative Gram-positive bacteria, Gram-negative bacteria and the fungus. It was worthwhile to note that some compounds could be used as potential antibacterial agents. (C) 2015 Elsevier Ltd. All rights reserved.

  A metal-organic complex [Cd-2(L)(N-3)(4)]. DMF was prepared by the reaction of Cd(NO3)(2)center dot 4H(2)O, NaN3 and ligand L (L: 1,4-bis(bis(3,5-dimethyl-1H-pyrazol-1-yl)methyl)benzene) in a DMF system. And the complex was characterized by elemental analysis, IR spectroscopy, UV-vis spectroscopy, thermal gravimetric technology, X-ray powder diffraction and single-crystal X-ray diffraction. Furthermore, the complex was combined with Bi2WO6 to form a composite, which was used as photocatalyst to degrade the basic dye methylene blue (MB) under the Xe lamp irradiation. The result revealed that the photocatalytic activity of the composite was better than that of the pure Bi2WO6 and the complex. In addition, the mechanism of the photocatalysis was also studied.

  New approaches have been proposed for the synthesis of compounds containing two bis(1H-pyrazol-1-yl)methane fragments. Nucleophilic replacement of the halogen atoms in appropriate tetrabromo derivatives by pyrazoles in the superbasic system KOH-DMSO gave ditopic chelating ligands: 1,1,2,2-tetrakis(1H-pyrazol-1-yl)ethane, 1,4-bis[bis(1H-pyrazol-1-yl)methyl]benzene, and 1,4-bis[bis(3,5-dimethyl-1H-pyrazol-1-yl)methyl]benzene. 1,4-Bis[bis(1H-pyrazol-1-yl)methyl]benzene was also synthesized by reaction of 1H-pyrazole with terephthalaldehyde in the presence of thionyl chloride. 1,1,2,2-Tetrakis(1H-pyrazol-1-yl)ethane was converted into the corresponding tetraiodo and tetranitro derivatives.
