  synthetic method for the synthesis of the complexes cis-Pt(amine)2R(COO)2 is compared to two other methods involving the use of either barium dicarboxylate or sodium carboxylate. Pt(II) compounds with monodentate and bidentate amines were studied. The reaction involves the use of a silver dicarboxylato complex, which is the intermediate in the new synthetic procedure. The crystal structure of the silver intermediate

  摘要将一种新颖的合成顺式-Pt（胺）2R（COO）2配合物的合成方法与另外两种涉及使用二羧酸钡或羧酸钠的合成方法进行了比较。研究了含单齿和双齿胺的Pt（II）化合物。该反应涉及使用二羧酸银配合物，该配合物是新的合成方法的中间体。通过X射线衍射测定具有配体1，1-环丁烷二羧酸酯（1，1-CBDCA）的银中间体的晶体结构。晶体Ag2（1,1-CBDCA）具有非常有趣的3-D扩展结构。通过多核（1H，13C和195Pt）磁共振波谱研究了溶液中的顺式-Pt（胺）2R（COO）2配合物，但溶解度很低。发现D2O是最好的溶剂。在195Pt NMR中，与含有单齿胺的那些相比，在更高的视野下观察到了含有二齿胺形成五元螯合物的配合物。NH3化合物的共振也比伯胺配合物的共振场低。除1，2-CBDCA以外，所有二羧基配体均形成六元螯合物，其Pt（II）化合物在比其他化合物更低的电场下观察到。通过X射线衍射法确认了Pt（en）（1

  D2O. Under these experimental conditions, a very slow cleavage of the Met–Gly amide bond was observed and this hydrolytic reaction proceeds through the intermediate [Pt(L)(H2O)(MeCOMet–Gly–S)]+ complex. In general, it can be concluded that faster hydrolytic cleavage of the MeCOMet–Gly dipeptide was observed in the reaction with the chloride complex than with corresponding CBDCA Pt(II) complexes. The

  可以得出结论，与相应的CBDCA Pt（II）配合物相比，在与氯化物配合物的反应中观察到MeCOMet-Gly二肽的水解裂解更快。还通过1H NMR光谱研究了Pt（II）配合物对MeCOMet-Gly二肽中酰胺键水解裂解的空间效应。已发现，水解速率随着CBDCA和氯铂Pt（II）配合物的空间体积增加而降低（en> 1,2-pn> dach）。这些结果有助于更好地理解Pt（II）抗肿瘤药物的毒副作用，在设计新的潜在的Pt（II）抗肿瘤药物（最好是低毒副作用）时应予以考虑。还通过1H NMR光谱研究了Pt（II）配合物对MeCOMet-Gly二肽中酰胺键水解裂解的空间效应。已发现，水解速率随CBDCA和氯铂Pt（II）配合物的空间体积增加而降低（en> 1,2-pn> dach）。这些结果有助于更好地理解Pt（II）抗肿瘤药物的毒副作用，在设计新的潜在的Pt（II）抗肿瘤药物（最好是低毒副作用）时应予以考虑。还通过1H

  The X-ray crystal structure of [Pt(en)(CBDCA-O,O′)] 1, an analogue of the anticancer drug carboplatin, shows that platinum has an approximate square-planar coordination. The crystals are orthorhombic with space group Pnma. The Pt-CBDCA chelate ring adopts a flattened-boat conformation, similar to that found for carboplatin, and the Pt-ethylenediamine chelate ring exhibits both δ and λ conformations

  抗癌药卡铂类似物[Pt（en）（CBDCA- O，O '）] 1的X射线晶体结构表明铂具有近似的方形-平面配位。晶体是正交晶体，具有空间群PnMA。Pt-CBDCA螯合环采用扁平的舟形构象，与卡铂相似，Pt-乙二胺螯合环同时具有相同的δ和λ构象。通过13 C CP / MAS NMR光谱观察到乙二胺螯合环的倒置。确定317 K处的交换速率和活化自由能（ΔG ‡）约为。415 s -1和62 kJ mol-1。CBDCA配体似乎对环的动力学有直接影响。还讨论了CBDCA环的构象灵活性。螯合铂络合物中的这种动态过程可能在抗癌络合物的生物识别中发挥作用。

  A series of platinum(II) complexes of formulae cis-[Pt(Am)(2)X-2] (where Am represents an inert amine and X a labile (carboxylato) ligand) have been prepared and characterized by elemental analysis, ESI-MS, IR and H-1 NMR spectroscopy. The single-crystal molecular structures were determined for cis-[Pt(opea)(cbdca-2H)], cis-[Pt(hmpy)(cbdca-2H)], cis-[Pt(NH3)(2)(bzmal-2H)] and cis-[Pt(hmpy)(mu-dcch-2H)(2)] (where opea is picolylamine, hmpy represents 4-hydroxymethylpyridine, cbdca-2H, is 1,1-cyclobutanedicarboxylate anion, bzmal-2H stands for benzylmalonate anion and dcch-2H is trans-1,2-cyclohexanedicarboxylate anion). The interaction of all compounds with DNA was investigated with different techniques: viscosity measurements and emission fluorescence spectroscopy were used to investigate the changes induced by the binding of the platinum compounds to calf-thymus DNA, while atomic force microscopy and electrophoretic mobility allowed evaluating the potential alterations of pBR322 plasmid DNA. The cytotoxic behavior of the platinum compounds on human leukemia HL-60 tumor cell lines was also examined. (C) 2012 Elsevier B. V. All rights reserved.
