The aim of this thesis was to explore the statistical physics and the mechanical properties of individual biomolecules, to study their interactions, and to develop new techniques based on atomic force microscopy (AFM). First, we exploit the high resolution ...
A series of ruthenium, osmium and rhodium complexes utilizing pta, (1,3,5-triaza-7-phosphatricyclo-[3.3.1.1]decane) and pta-Me+, its N-methyl derivative, have been synthesized. Their characterization by 1H and 31P NMR spectroscopy, ESI-MS and single crysta ...
The preparation of oligoribonucleotides is of great interest for structural and functional investigations in biomolecular chemistry and biology. Relevant RNAs are relatively long and contain often modifications. Two methods for their preparation are curren ...
Duocarmycins are a potent class of antitumor agents. Their activity arises by their covalent binding to adenine nucleobases of DNA. We use classical mol. dynamics and hybrid (QM/MM) Car-Parrinello mol. dynamics simulations to study non-covalent and covalen ...
The first results of a study aiming at an efficient prepn. of a large variety of 2'-O-[(triisopropylsilyl)oxy]methyl(=tom)-protected ribonucleoside phosphoramidite building blocks contg. modified nucleobases are reported. All of the here presented nucleosi ...
