Nucleic Acids – Genes, Drugs, Molecular Lego and More

Chemically modified nucleic acids find widespread use as tools in research, as diagnostic reagents and even as pharmaceutical compounds. On the background of antisense research and development, the synthesis and evaluation of modified oligonucleotides was intensively pursued in the early to mid nineties in corporate research of former Ciba. Most of these efforts concentrated on the development of sugar and/or backbone-modified derivatives for pharmaceutical applications. Additionally, oligonucleotide metal conjugates were investigated with the goal to develop artificial ribonucleases. Since the turn of the millennium also the potential of non-nucleosidic and non-hydrogen bonding building blocks has increasingly been recognized. Such derivatives possess unique properties that may have an impact in the fields of materials and genetic research. In this brief account, we take a personal look back on some past as well as some recent results.
