  Synthesis, structural, and biological evaluation of the arene-linked pyrazolyl methane ligands and their d9/d10 metal complexes

  摘要：

  A series of the p-bis[(1-pyrazolyl)methyl] benzene ligands (L-1-L-6) in the DMSO system were synthesized. In the mean time, by using the ligands as a linker, a new family of transition metal coordination polymers, namely, [Cu-2(L-1)(2)Cl-4] (1), [Cu-2(L-2)(2)Cl-4] (2), [Ag(L-2)(NO3)] (3). [Zn-2(L-2)(2)(SCN)(4)] (4) and [Cd-2(L-2)(SCN)(4)] (5) [L-1 = 1,4-bis((1H-pyrazol-1-yl)methyl)benzene; L-2 = 1,4-bis(3,5-dimethyl-1H-pyrazol-1-yl)methyl)benzene] have been constructed by the reaction of the p-bis[(1-pyrazolyl)methyl]benzene and corresponding to the transition metal compounds in a mixed solution of CH3OH/C2H5OH at mild temperature condition. All the coordination polymers and p-bis[(1-pyrazolyl)methyl]benzene ligands were characterized by elemental analysis, IR spectroscopy, H-1 NMR and C-13 NMR, and some of them were characterized by UV spectroscopy, thermogravimetric analysis, X-ray powder and X-ray single-crystal diffraction. Structural analyses reveal that the ligands L-3-L-5 (L-3 = 1,4-bis((4-iodo-1H-pyrazol-1-yl)methyl)benzene, L-4 = 1,4-bis((4-iodo-3,5-dimethyl-1H-pyrazol-1-yl)methyl)benzene, L-5 = 1,4-bis((4-nitro-1H-pyrazol-1-yl)methyl) benzene,L-6 = 1,4-bis((4-nitro-3,5-dimethyl-1H-pyrazol-1-yl) methyl) benzene) are discrete organic compound molecules and the complexes 1-5 are 1D M-L-M coordination polymers, which are further interlinked via hydrogen bonds resulting in 2D or even 3D supermolecular networks. The luminescent properties of the coordination polymers 3,4 and 5 were examined by luminescence spectra. The analytic results indicate that different metal complexes with the same ligand have different influence on the characteristic photoluminescence. Furthermore, the cytotoxicity of the ligands L-1-L-6 and complexes 1-5 were evaluated against hepG2 cells. For the ligands of L-1-L-6, the different substituents of the pyrazole ring slightly influenced the cytotoxicity of the cell. It is found that nitro-compounds have shown the highest cytotoxicity under the same concentration condition. The cytotoxic activity of the complexes 1-5 are strongly increased by the introduction of the transition metals. (c) 2012 Elsevier Ltd. All rights reserved.

  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.
