A new method for the determination of the relative affinity of a ligand against various dsDNA sequences is presented by using electrospray ionization time-of-flight mass spectrometry (ESI-QTOF) mass spectrometry. The principle is described here through the complexation of double-stranded DNA...

Isopropyl-thiazole ((iPr)Th) represents a new addition to the building blocks of nucleic acid minor groove-binding molecules. The DNA decamer duplex d(CGACTAGTCG)(2) is bound by a short lexitropsin of sequence formyl-PyPy(iPr)Th-Dp (where Py represents N-methyl pyrrole, (iPr)Th represents thiazole with an...

The molecular conformation of a synthetic branched, 4-way DNA Holliday junction (HJ) was electrochemically switched between the open and closed (stacked) conformers. Switching was achieved by electrochemically induced quantitative release of Mg(2+) ions from the oxidised poly(N-methylpyrrole) film (PPy), which...

Eight novel polyamides containing N-methylpyrrole were designed to target the sequence (5'-CTGCATATAAGCAG-3'/5'-CTGCTTATATGCAG-3') of the TATA box element of the HIV-1 promoter DNA. The non-covalent complexes of the promoter DNA and the polyamides were investigated by electrospray ionization (ESI) mass spectrometry...
