Uranyle Complexes: synthesis, evaluation of biological activity
In this research, some of the inorganic complexes of uranyl with N- donor ligandswere synthesized. Complexes were characteriezed by FT-IR and UV spectra, ¹HNMR,¹³CNMR and some physical properties. The uranyl unit (UO2) is composed of a center ofuranium atom with the charge (+6) and two oxygen atom by forming two U=O double bonds.The structure is linear (O=U=O, 180) and usually stable. So other ...
متن کاملThe DNA and RNA specificity of eilatin Ru(II) complexes as compared to eilatin and ethidium bromide.
Eilatin-containing ruthenium complexes bind to a broad range of different nucleic acids including: calf thymus (CT) DNA, tRNA(Phe), polymeric RNAs and DNAs, and viral RNAs including the HIV-1 RRE and TAR. The nucleic acid specificity of Lambda- and Delta-[Ru(bpy)2eilatin]2+ have been compared to that of the 'free' eilatin ligand, and to the classic intercalating agent ethidium bromide. Interest...
متن کاملMechanism of Ethidium Bromide Fluorescence Enhancement on
The mechanism of the enhancement of the fluorescence of ethidium bromide on binding to double helical RNA and DNA has been investigated. From an examination of the effect of different solvents on the fluorescence lifetime, quenching of fluorescence by proton acceptors, and the substantial lengthening of lifetime observed upon deuteration of the amino protons, regardless of the medium, we conclu...
متن کاملEthidium bromide-resistant mutant of Bacillus subtilis.
An ethidium bromide-resistant mutant (EB8) derived from a Marburg strain of Bacillus subtilis was found to be conditionally resistant to 10 mug of ethidium bromide per ml. Expression of resistance is complete only during vegetative growth at incubation temperatures above 30 C in complex medium or minimal medium supplemented with Casamino Acids. Strain EB8 is cross-resistant to acriflavine and p...
متن کاملComparison of various ultraviolet sources for fluorescent detection of ethidium bromide-DNA complexes in polyacrylamide gels.
Ultraviolet sources with output wavelengths or 254, 300, and 366 nm were compared for detection of ethidium bromide-DNA complexes in acrylamide gels. The 254and 300-nni sources were both much more sensitive than the 366-nni source. The 254-nni .source produced a great deal of photodamage, photonickingand photodimerization, and photobleaching, while the longer wavelength sources cause little dam...
