[source] New Anthraquinone Derivatives as Electrochemical Redox Indicators for the Visualization of the DNA Hybridization ProcessELECTROANALYSIS, Issue 1 2010Agata Kowalczyk Abstract Interactions of dsDNA and ssDNA, at the surface of gold and silver electrodes, with three novel anthraquinone derivatives: 3-(9,,10,-dioxo-9,,10,-dihydro-anthracen-1-yl)-7,11-di(carboxymethyl)-3,7,11-triazatridecanedioic acid, (AQ-1); 1-(9,,10,-dioxo-9,,10,-dihydro-anthracen-1yl)-9-carboxymethyl-5-methyl-1,5,9-triazaundecanoicacid, (AQ-2); and N -(2-(9,10-dioxo-9,10-dihydro-anthracen-1-ylamino)ethyl)-2-(1,4,10,13-tetraoxa-7,16-diazacyclooctadecan-7-yl)acetamide, (AQ-3) are studied. These derivatives are well soluble in water and phosphate buffer solutions. The square wave voltammetric behavior of these redox indicators is described and the parameters of interactions with DNA are reported. It is also pointed out that these compounds can be employed as the hybridization indicators. The difference in the binding ability of the particular redox indicator to single and double stranded DNA can be used for the detection of the complementary nucleic acids.

[source] Structure of a stacked anthraquinone,DNA complexACTA CRYSTALLOGRAPHICA SECTION F (ELECTRONIC), Issue 9 2010Daniela De Luchi The crystal structure of the telomeric sequence d(UBrAGG) interacting with an anthraquinone derivative has been solved by MAD. In all previously studied complexes of intercalating drugs, the drug is usually sandwiched between two DNA base pairs. Instead, the present structure looks like a crystal of stacked anthraquinone molecules in which isolated base pairs are intercalated. Unusual base pairs are present in the structure, such as G·G and A·UBr reverse Watson,Crick base pairs.

[source] Copper Nanoparticles on Charcoal for Multicomponent Catalytic Synthesis of 1,2,3-Triazole Derivatives from Benzyl Halides or Alkyl Halides, Terminal Alkynes and Sodium Azide in Water as a "Green" SolventADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 1-2 2009Hashem Sharghi Abstract A one-pot procedure for synthesis of 1,2,3-triazole derivatives via the three-component coupling (TCC) reaction between terminal alkynes, benzyl or alkyl halides, and sodium azide in the presences of 1,mol% nanoparticles copper/carbon (Cu/C) catalyst has been developed. The catalyst showed high catalytic activity and 1,4-regioselectivity for the [3+2],Huisgen cycloaddition in water as a "green" solvent and good to excellent yields were obtained in all cases. This procedure eliminates the need to handle organic azides, and they are generated in situ. The reaction has a broad scope and is especially practical for the synthesis of new azacrown ether and anthraquinone derivatives of triazole. The heterogeneous catalysts were fully characterized by scanning electron microscopy (SEM), atomic forced microscopy (AFM), X-ray diffraction (XRD), inductively coupled plasma (ICP) analysis and FT-IR experimental techniques. The catalyst was recycled ten times without significant loss of activity. [source] | ||||||||||
