Description

Outline of the talkVirtually all drugs are molecular (be them large or small) capable of binding to one or more target proteins of biomedical interest. Thus, the isolation of binders to protein targets is a central step in the drug discovery process. Two methodologies, which rely on the preparation of very large encoded combinatorial libraries, have revolutionized the way protein ligands are discovered. On one hand, antibody phage display libraries (pioneered by Sir Gregory Winter, Nobel Prize Chemistry 2018) allow the construction and screening of very large collections, comprising billions of different antibodies. On the other hand, DNA-encoded chemical libraries allow the construction and screening of large collections of small molecules, individually coupled to DNA tags, serving as amplifiable indentification barcodes. In this lecture, I will show how antibody phage libraries and DNA-encoded chemical libraries have been used in my laboratory (in collaboration with the Philogen group), in order to generate products, which are currently investigated in clinical trials.
