homogeneous catalysis in oxidative coupling of substrates and designing of metallo-therapeutics, this research study demonstrates the synthesis, structural description, bio-mimics of phenazine oxidase activity and in-vitroantibacterial as well as antiproliferative activity of a mononuclear aurum(III) complex, [Au(bpy)Cl2]NO3 (1) [bpy = 2,2′-bipyridine]. The crystal structure analysis of 1 reveals that
worldwide. To prevent bacterial infectious diseases from spreading, it is of critical importance to develop convenient, ultrasensitive, and cost-efficient methods for bacteria detection. Here, an electrochemicaldetector of a functional two-dimensional (2D) metal–organic framework (MOF) nanozyme was developed for the sensitive detection of pathogenic Staphylococcus aureus. A dual recognition strategy consisting

revealing relatively fast exchange with no significant influence from the polycyclic aromaticdiamines. The calf thymus DNA (CT-DNA) binding of the complexes increased dramatically upon extending the aromatic component of the diamines, as evaluated by changes in absorption spectra upon titration with different concentrations of CT-DNA. An intercalation binding mode was established for the complexes
添加复合物 1 和 2 后,利用 CT-DNA 相对粘度的增加,为复合物建立了嵌入结合模式。 理论研究表明,所有复合物都强烈倾向于用鸟嘌呤代替水,并且相对强的 Ru–鸟嘌呤键。芳香系统的平面可以呈现支持与 DNA 和共价结合的非经典相互作用的角度,从而导致更高的结合亲和力。本研究中说明的钌芳烃具有有希望的抗癌活性,其对三种细胞系的半数最大抑制浓度 (IC50) 值与顺铂相当或更好。和相对较强的 Ru-Nguanine 键。芳香系统的平面可以呈现支持与 DNA 和共价结合的非经典相互作用的角度,从而导致更高的结合亲和力。本研究中说明的钌芳烃具有有希望的抗癌活性,其对三种细胞系的半数最大抑制浓度 (IC50) 值与顺铂相当或更好。和相对较强的 Ru-Nguanine 键。芳香系统的平面可以呈现支持与 DNA 和共价结合的非经典相互作用的角度,从而导致更高的结合亲和力。本研究中说明的钌芳烃具有有
