Pyrene–nucleobase conjugates: synthesis, oligonucleotide binding and confocal bioimaging studies
Fluorescent pyrene-linker-nucleobase (nucleobase = thymine, adenine) conjugates with carbonyl and hydroxy functionalities in the linker were synthesized and characterized. X-ray single-crystal structure analysis performed for the pyrene-C(O)CH2CH2-thymine (2) conjugate reveals dimers of molecules 2 stabilized by hydrogen bonds between the thymine moieties. The photochemical characterization sho...
متن کاملOligonucleotide studies. Optical rotatory dispersion of five homodinucleotides.
1. The optical rotatory dispersion (ORD) of five homodinucleotides, ApAp(3'), CpCp(3'), GpGp(3'), IpIp(3') and UpUp(3') (where A, C, G, I and U represent adenosine, cytidine, guanosine, inosine and uridine respectively, and p to the left of a nucleoside symbol indicates a 5'-phosphate and to the right it indicates a 3'-phosphate), were measured as a function of pH, ionic strength and Mg(2+) con...
متن کاملAFM and electroanalytical studies of synthetic oligonucleotide hybridization.
The first and most important step in the development and manufacture of a sensitive DNA-biosensor for hybridization detection is the immobilization procedure of the nucleic acid probe on the transducer surface, maintaining its mobility and conformational flexibility. MAC Mode AFM images were used to demonstrate that oligonucleotide (ODN) molecules adsorb spontaneously at the electrode surface. ...
متن کاملSynthesis of lipid-oligonucleotide conjugates for RNA interference studies.
The synthesis of RNA molecules carrying lipids at their 3'-termini and 5'-termini is reported. These conjugates were fully characterized by MALDI-TOF mass spectrometry and HPLC chromatography. The ability of these conjugates to silence gene expression was evaluated in the inhibition of the tumor necrosis factor. All the lipid-siRNA derivatives were compatible with RNA interference machinery if ...
متن کاملPoly(oligonucleotide)
Here we report the preparation of poly(oligonucleotide) brush polymers and amphiphilic brush copolymers from nucleic acid monomers via graft-through polymerization. We describe the polymerization of PNA-norbornyl monomers to yield poly-PNA (poly(peptide nucleic acid)) via ring-opening metathesis polymerization (ROMP) with the initiator, (IMesH2)(C5H5N)2(Cl)2RuCHPh.1 In addition, we present the ...
