A series of polypyridyl complexes have been synthesized. All polypyridyl complexes and some of the soluble ligands have been assayed for antitumor activity in vitro against the HL-60 (the human leucocytoma) cells, BEL-7402 (the human liver carcinoma) cells, KB (the human nasopharyngeal carcinoma) cells and HELA (the human adenocarcinoma of cervix) cells.(More)
The ligand ODHIP (3,4-dihydroxyl-imidazo[4,5-f][1,10]phenanthroline) and its cobalt(III) complex [Co(bpy)(2)(ODHIP)](3+) were synthesized and characterized. Binding of this complex with calf thymus DNA has been investigated by spectroscopic methods and viscosity. The experimental results indicated that the complex bound to DNA by intercalation. In Tris(More)
The Aspergillus niger strain ZBY-7 was selected as the original strain of glucose-6-phosphate dehydrogenase production. After mutagenesis of the strain by means of UV irradiation and nitrosoguanidine, mutants of Aspergillus niger resistant to a certain metabolic inhibitor were obtained. Five of the mutants showed increased glucose-6-phosphate dehydrogenase(More)
Two novel ruthenium(II) complexes, [Ru(pztp)2(phen)](ClO4)2 and [Ru(pztp)2(bpy)](ClO4)2, have been synthesized and characterized by UV/Vis and 1H NMR spectroscopies and mass spectrometry. The MeCN solutions of both complexes display fluorescence that was found to be highly sensitive to the presence and concentration of water. The complexes behave like a(More)
A series of enantiomeric polypyridyl ruthenium(II) complexes Delta- and Lambda-[Ru(bpy)2CNOIP](PF6)2 (Delta-1 and Lambda-1; BPY=2,2'-bipyridine, CNOIP=2-(2-chloro-5-nitrophenyl)imidazo[4,5-f][1,10]phenanthroline), Delta- and Lambda-[Ru(bpy)2HPIP](PF6)2 (Delta-2 and Lambda-2; HPIP=2-(2-hydroxyphenyl)imidazo[4,5-f][1,10]phenanthroline), Delta- and(More)
A mitochondria-targeting nanoplatform for near-infrared-light-controlled release of nitric oxide accompanied by photothermal therapy was developed, which consists of ruthenium nitrosyl functionalized N-doped graphene quantum dots and a triphenylphosphonium moiety. The nanoplatform demonstrated both in vitro and in vivo anti-tumor efficacy upon irradiation(More)
A facile approach to prepare Cu complexes for an efficient oxygen reduction reaction (ORR) was developed. Copper complexes of 5-nitrophenanthroline were sandwiched between polyvinylimidazole layers wrapped on carbon nanotubes, which showed ORR activity comparable to a Pt/C catalyst in alkaline media.
Nitric oxide (NO) plays a key role in various physiological and pathological processes. It is of great significance in developing a platform that enables exogenous delivery of NO spatiotemporally to a targeted site for realizing NO-mediated therapy. We report herein a stable, multifunctional NO-delivery nanoplatform that is capable of target directing,(More)
