A circular dichroism study uncovers a two-step interaction of antitumor azolato-bridged dinuclear platinum(II) complexes with calf thymus DNA.

چکیده
The interactions of four antitumor azolato-bridged dinuclear platinum(II) complexes, [{cis-Pt(NH(3))(2)}(2)(μ-OH)(μ-azolato)](2+), with calf thymus DNA were monitored dose- and time-dependently, by using circular dichroism. Complexes 1-4 reacted with DNA via a two-step interaction that comprised a prompt diffusion-controlled reaction, which induced a B- to C-form transition, and a relatively slow temperature-dependent reaction.

متن کاملSynthesis of antitumor azolato-bridged dinuclear platinum(ii) complexes with in vivo antitumor efficacy and unique in vitro cytotoxicity profiles.
We synthesised four tetrazolato-bridged dinuclear Pt(ii) complexes, [{cis-Pt(NH3)2}2(μ-OH)(μ-5-R-tetrazolato-N2,N3)](n+), where R is CH3 (1), C6H5 (2), CH2COOC2H5 (3), or CH2COO(-) (4) and n = 2 (1-3) or 1 (4). Their structures were characterised by (1)H, (13)C, and (195)Pt NMR spectroscopy, mass spectrometry, and elemental analysis, and the crystal structure of 1 was determined by X-ray crysta...

In this study two platinum(II) and palladium(II) complexes of the type [M(bpy)(pip-dtc)]NO3 (where M=Pt(II) or Pd(II), bpy=2,2'-bipyridine, pip-dtc=piperidinedithiocarbamate) were synthesized by reaction between diaquo-2,2'-bipyridine Pt(II)/Pd(II) nitrate and sodium salt of dithiocarbamate. These cationic water soluble complexes were characterized by elemental analysis, molar conductance, IR, ...
متن کاملChromatin folding and DNA replication inhibition mediated by a highly antitumor-active tetrazolato-bridged dinuclear platinum(II) complex
Chromatin DNA must be read out for various cellular functions, and copied for the next cell division. These processes are targets of many anticancer agents. Platinum-based drugs, such as cisplatin, have been used extensively in cancer chemotherapy. The drug-DNA interaction causes DNA crosslinks and subsequent cytotoxicity. Recently, it was reported that an azolato-bridged dinuclear platinum(II)...

The ability of small molecules to perturb the natural structure and dynamics of nucleic acids is intriguing and has potential applications in cancer therapeutics. This work reports the synthesis, characterization, cytotoxicity and DNA-binding studies of two cytotoxic and intercalative [M(bpy)(pyrr-dtc)]NO3 complexes (where M = Pt(II) and Pd(II), bpy = 2,2´-bipyridine and pyrr-dtc = p...
