  • Synthesis of New Cationic Schiff Base Complexes of Copper(II) and Their Selective Binding with DNA

    A series of cationic salen-type Schiff base complexes of copper(II), the general formula of which is [CuR3N+–CH2–C6H3(O−)–CH=N–}2X]Br2 (R: CH3, C2H5, C3H7, C4H9; X: C2H4, C3H6, C6H10, C6H4, C10H6), was newly prepared, and the molecular structure of complex 1 (R = CH3, X = C2H4) was determined by an X-ray crystal structure analysis. The binding mode and binding constants (Kb) of all the complexes with calf thymus DNA were investigated at an ionic strength of I = 0.05(NaCl + HEPES buffer, pH = 7.2) using induced CD and the UV-vis spectra. Those complexes with aliphatic X group selectively bound to the groove of DNA, and the Kb’s were in the range of 102—103 mol dm−3 (site size base pairs n = 7.2—7.4). However, those with aromatic X group selectivity intercalated to the base pairs, and the Kb’s were in the range of 104—105mol dm−3 (n = 2.8—4.0). These binding modes were confirmed based on the salt dependence of Kb’s. In addition, 1 and 10 (R = CH3, X = C6H4) were found to exhibit AT-sequence affinity from the induced CD spectra and Kb’s for poly(dA-dT)–poly(dA-dT), poly(dG-dC)–poly(dG-dC), and poly(dA-dC)–poly(dT-dG).
    一系列阳离子Salen型Schiff碱(II)络合物被新配制,其一般式为[CuR3N+–CH2C6H3(O−)–CH=N–}2X]Br2(R:CH3C2H5C3H7C4H9;X:C2H4C3H6C6H10C6H4C10H6),并通过X射线晶体结构分析确定了络合物1(R = ,X = )的分子结构。以离子强度I = 0.05(NaCl + HEPES缓冲液,pH = 7.2)为条件,使用诱导圆二色谱(CD)和紫外可见光谱研究了所有络合物与小牛胸腺DNA的结合模式和结合常数(Kb)。那些具有脂肪族X基团的络合物选择性地结合到DNA的槽口,Kb的范围在102—103 mol dm−3(位点基对数n = 7.2—7.4)。而具有芳香族X基团的络合物则选择性地插入到基对中,Kb的范围在104—105 mol dm−3(n = 2.8—4.0)。这些结合模式基于Kb的盐依赖性得到了确认。此外,发现1和10(R = ,X = )在诱导CD光谱和针对聚(dA-dT)–聚(dA-dT)、聚(dG-dC)–聚(dG-dC)和聚(dA-dC)–聚(dT-dG)的Kb中表现出AT序列亲和力。

    DNA-fibre ESR measurements reveal that the orientation of water-soluble cationic salen-type Schiff base complexes of copper(II) on DNA changes by modification of the bridging group between two imino nitrogens in the complex; the 1,2-phenylenediamine and 2,3-naphthalenediamine bridges enable the complex to intercalate to DNA, while the ethylenediamine bridge induces groove binding.

Remarkably, the Gibbs formation free energy calculated for the intercalation complexes of 1, 2 and 3 with [dodeca(dA-dT)]2 in the implicit water solution is in agreement with the experimental Gibbs free energy values obtained from the DNA-binding constants as ΔG° = −RT ln(Kb).

  • DNA interaction of CuII, NiII and ZnII functionalized salphen complexes: studies by linear dichroism, gel electrophoresis and PCR

    The interaction of salphen-type NiII, CuII and ZnII complexes with native DNA was investigated by exploiting linear dichroism experiments. The NiII complex behaves as a typical intercalator, binding strongly and stiffening and unwinding the DNA. The strength of the DNA interaction is slightly weaker for the copper complex and much weaker for the zinc complex. Plasmid-DNA gel electrophoresis experiments indicated that while CuII and ZnII complexes do not induce the unwinding of supercoiled DNA, the NiII complex has a nuclease activity without the addition of external agents. On the other hand, as shown in the PCR assays, we demonstrate that, at the used concentrations, only the CuII complex is able to inhibit the DNA amplification mediated by Taq DNA polymerase. In this paper we have also reported a detailed characterization of the three compounds including 2D-NMR and ESI-mass experiments and X-ray single crystal structure of the copper and nickel compounds.
    通过线性二色性实验研究了 Salphen 型 NiII、CuII 和 ZnII 配合物与天然 DNA 的相互作用。 NiII 复合物表现为典型的嵌入剂,强烈结合并使 DNA 硬化和解旋。络合物的 DNA 相互作用强度稍弱,而络合物的 DNA 相互作用强度则弱得多。质粒-DNA凝胶电泳实验表明,虽然CuII和ZnII复合物不会诱导超螺旋DNA解旋,但NiII复合物在不添加外部试剂的情况下具有核酸酶活性。另一方面,如 PCR 测定所示,我们证明,在所使用的浓度下,只有 CuII 复合物能够抑制 Taq DNA 聚合酶介导的 DNA 扩增。在本文中,我们还报道了这三种化合物的详细表征,包括化合物的 2D-NMR 和 ESI 质量实验以及 X 射线单晶结构。

    Novel nickel(II) (1) and zinc(II) (2) complexes of a Salen-like ligand, carrying a pyrimidine ring on the N,N' bridge, were synthesized and characterized. Their interaction with duplex and G-quadruplex DNA was investigated in aqueous solution through UV-visible absorption, circular dichroism and viscometry measurements. The results obtained point out that, while the zinc(II) complex does not interact
