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

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
In order to investigate the influence of molecular size and pyrrole (Py)/imidazole (Im) content on the cell permeability of Py-Im-polyamide-fluorescein conjugates we systematically designed the Py-polyamides and Im-polyamides. Flow cytometric analysis revealed that Py-polyamides, even those with large molecular size

Electrospray ionization mass spectrometry (ESI-MS) was used to investigate noncovalent complexes formed between four novel polyamides containing N-methylpyrrole (Py) and N-methylimidazole (Im), and human telomeric DNA. Of the four polyamides investigated, PyPyPygammaImImImbetaDp (3) had the highest binding affinity towards the

We investigated the reaction dynamics of N-methylpyrrole (NMP) along the N-CH3 coordinate, upon excitation energies below 6.4 eV. Ours and previous experiments show clearly the existence of different reaction channels leading to slow and fast fragment production whose relative efficiency
