  Anticancer Activity of Self-Assembled Molecular Rectangles via Arene–Ruthenium Acceptors and a New Unsymmetrical Amide Ligand

  摘要：

  Two new and large molecular rectangles 4 and 5 were synthesized from two different arene-ruthenium [Ru-2(mu-eta(4)-C2O4)(MeOH)(2)(eta(6)-p-(PrC6H4Me)-C-i)(2)][O3SCF3](2) (2) and [Ru-2(p-cymene)(2)(donq)(OH2)(2)][O3SCF3](2) (donq = 5,8-dioxydo-1,4-naphthaquinonato) (3) acceptors and a new unsymmetrical N-(4-(pyridin-4-ylethynyl)phenyl) isonicotinamide (1) donor ligand. Xray crystallography of 4 confirmed a molecular rectangle. The H-1 NMR spectra of both rectangles 4 and 5 showed a mixture of two structural, head-to-tail (HTT) and head-to-head (HTH), type isomers in a 1:1 ratio. The cytotoxicities, of both rectangles have been established against Colo320 (colorectal cancer), A549 (lung cancer), MCF-7 (breast cancer), and H1299 (lung cancer) human cancer,cell lines. The cytotoxicity of rectangle 5 was found to be considerably stronger against all cancer cell lines than that of the reference drug cisplatin.

  tetranuclear cations of the general formula [Ru4(arene)4()2(O O)2]4+. Both rectangles were isolated in good yields as triflate salts and were characterized by multinuclear NMR, ESI‐MS, UV/Vis, and photoluminescence spectroscopy. The crystal structure of 5 was determined by X‐ray diffraction. Luminescent rectangle 5 was used for anion sensing with an amide ligand as a hydrogen‐bond donor and an arene–ruthenium

  Two new crystalline coordination polymers have been synthesized with Zn2+ and Cd2+ ions using an N-(4-(pyridinyl-4-ethynyl)phenyl)-isonicotinamide (HL) donor ligand. The ligand readily reacts with metal nitrate in DMF to afford 1-dimensional (1D) coordination polymers 1 and 2 comprising a repeating unit of [Zn(HL)(NO3)(2)(DMF)]center dot DMF and [Cd(HL)(NO3)(2)(DMF)]center dot DMF, respectively. Both complexes 1 and 2 were characterized by IR spectroscopy, elemental analysis, thermogravimetric analysis (TGA), and X-ray diffraction. Both complexes contained a 1D chain in which crystallography revealed two metal ions were connected by each ligand. The weak pi-pi stacking interactions and intermolecular hydrogen bonds resulted in the one-dimensional network structures. The photoluminescent properties for both complexes were also investigated.
