  Zinc(II) complexes with novel 1,3-thiazine/pyrazole derivative ligands: Synthesis, structural characterization and effect of coordination on the phagocytic activity of human neutrophils

  摘要：

  The new ligands 2-(1-pyrazolil)-1,3-thiazine (PzTz), 2-(3,5-dimethyl-1-pyrazolil)-1,3-thiazine (DMPzTz) and 2-(3,5-diphenyl-1-pyrazolil)-1,3-thiazine (DPhPzTz) and the complexes [ZnCl2(H2O)(PzTz)] (1), [ZnCl2(DMPzTz)] (2) and [ZnCl2(DPhPzTz)] (3) have been isolated and then characterized by elemental analysis, IR spectra and UV-Vis spectroscopy. Besides, the crystal structure of ligands PzTz and DPhPzTz and complexes 1-3 have been determined by single-crystal X-ray diffraction. In 1, the geometry around the Zn(II) atom can be considered a highly distorted trigonal bipyramid, with the metallic atom bonded to two chlorine atoms, one water molecule and one bidentate PzTz ligand. In 2 and 3, the environment around the metal ion can be described as a distorted tetrahedron with the zinc atom coordinated to one bidentate organic ligand molecule and two chloro ligands. In addition, the phagocytic function of human neutrophils treated with complexes 1-3, their organic ligands and ZnCl2 has been evaluated. The activity of cells enhanced in samples treated with 1, 2 and 3 with respect to the ones to which the inorganic salt, PzTz. DMPzTz or DPhPzTz were added. (C) 2011 Elsevier Ltd.

  ability was studied in three different human tumor cell lines, i.e., histiocytic lymphoma (U-937), promyelocytic leukemia (HL-60) and epithelial cervix carcinoma (HeLa) via cytotoxicity assay. The results showed moderate cytotoxic effect of the complexes on leukemic cell lines, with scarce effect on solid tumor cell line HeLa. Lower IC50 values were found for U-937 cell line, being 32.3 ± 1.2 µmol/dm3 for

  顺铂是当今最常用的化疗药物之一。然而，它会带来一些严重的副作用。为此，合成新的顺铂类似物对于改善当前的疗法至关重要。在这项工作中，提出了两种顺铂的方形平面 Pt(II) 类似物。这些类似物包括具有 3,5-二甲基吡唑环和噻嗪 (DMPzTz) 或噻唑啉 (DMPzTn) 环的双齿配体分子。化学表征包括单晶X射线衍射、红外光谱(IR)和元素分析。通过细胞毒性测定，在三种不同的人类肿瘤细胞系，即组织细胞淋巴瘤（U-937）、早幼粒细胞白血病（HL-60）和上皮性宫颈癌（HeLa）中研究了它们的潜在抗癌能力。结果表明，该复合物对白血病细胞系具有中等的细胞毒性作用，而对实体瘤细胞系 HeLa 几乎没有作用。U-937 细胞系的IC 50值较低， PtDMPzTn为 32.3 ± 1.2 µmol/dm 3 ，PtDMPzTz 为 43.0 ± 1.4 µmol/dm 3。与先前合成的吡唑环中具有苯

  The new ligands 2-(3,5-dimethyl-1-pyrazolyl)-2-thiazoline (DMPyTn) and 2-(3,5-diphenyl-1-pyrazolyl)-2-thiazoline (DPhPyTn) have been synthesized and characterized, and six cadmium(II) nitrato complexes with these two ligands and four other pyrazole/S,N-heterocyclic derivative ligands with different steric features, previously reported, have been prepared and structurally characterized by means of elemental analysis, single crystal X-ray diffraction and IR spectra, with the objective of determining the role played by the steric strains of the ligands on the metal ion coordination index and geometry. The effect of two factors has been analyzed: the bulk of the pyrazole ring substituents and the size of the S,N-heterocycle. The data indicate that there is a clear influence of the size of the organic ligands on the coordination environment of the Cd(II) ion. (C) 2011 Elsevier Ltd. All rights reserved.
