    Syntheses, spectra, photoinduced nitric oxide release and interactions with biomacromolecules of three nitrosylruthenium complexes
    摘要:
    Three nitrosylruthenium complexes, [RuCl(qn)L(NO)] (qn = 8-hydroxyquinoline; L = L-Asp, L-Lys and picp), have been synthesized. The photodynamic reactions of the three complexes were analyzed with time resolved FTIR spectroscopy and the photoinduced release of NO was confirmed by EPR via spin trapping of the NO free radical. The binding constants of the complexes with calf thymus DNA and human serum albumin were quantitatively determined by fluorescence spectroscopy, with a stronger binding being found for the [RuCl(qn)(picp)(NO)] (picp = 2-(4-carboxylphenyl)-imidazolium[4,5-f][1,10] phenanthroline) complex compared to the other two complexes. Photoirradiation of the complexes mixed with HSA solution resulted in a blue-shift of the vibrational frequency of NO and an increased amount of released NO. The cell toxicity of the complexes was screened to understand the effects of the different ligands on the biological activity of the Ru complexes. The [RuCl(qn)(picp)(NO)] complex showed better activity against the HepG-2 cell, with an IC50 value of 24.9 mu M without light and 13.8 mu M upon photoirradiation. Moreover, a comparison of photoinduced DNA cleavage and photodynamic cellular toxicity suggests the important role of the NO free radical. This study provides a strategy for the design of NO-donors and the potential application of Ru-NO complexes in photodynamic therapy. (C) 2020 Elsevier Ltd. All rights reserved.

Moreover, the binding constants of the complexes with calf thymus DNA and human serum albumin were calculated by fluorescence spectroscopy to understand the effects of the substituent groups on the biological activity. The [RuCl3(2cqn)(NO)]− complex had the highest binding constant, consistent with its high cytotoxicity. Thus, we developed an effective and simple method to control cytotoxic activities
    摘要(Ru)配合物由于其良好的光化学和光生物学特性,已潜在地用作DNA结构探针,细胞显像剂和抗癌药物,因此已被广泛研究。在这里,我们使用8-羟基喹啉(Hhqn)及其衍生物(2-甲基-8-喹啉[H2mqn]和2-配体为cholo-8-quiolinoline [H2cqn])(QN = hqn,2mqn或2cqn);通过X射线晶体衍射确认了它们的结构。[RuCl3(2cqn)(NO)]-络合物显示出比其他两种络合物更高的活性,在光下的IC50值为21.5 µM,在没有光照射的情况下的IC50值为100 µM。复合物诱导的抗增殖作用使细胞周期停滞在G2 / M期。此外,通过自旋捕获NO自由基确认了复合物中的光控实时NO释放。还证明了复合物的光化学DNA裂解,这可能是由于光诱导的自由基引起的。此外,通过荧光光谱法计算了与小牛胸腺DNA和人血清白蛋白的复合物的结合常数,以了解取代基对生物活性的影
