Selection of DNA‐Encoded Small Molecule Libraries Against Unmodified and Non‐Immobilized Protein Targets

Abstract

The selection of DNA-encoded libraries against biological targets has become an important discovery method in chemical biology and drug discovery, but the requirement of modified and immobilized targets remains a significant disadvantage. With a terminal protection strategy and ligand-induced photo-crosslinking, we show that iterated selections of DNA-encoded libraries can be realized with unmodified and non-immobilized protein targets.
