Abstract
DNA-encoded library (DEL) technology provided a powerful screening platform for identifying potential bioactive small molecules with high affinity to biologically interesting targets. Essential to a successful DEL campaign are the drug-like small molecular moieties of DNA-encoded libraries with expanded chemical space. Our laboratory has been working on developing and producing novel DNA-encoded libraries that complement current reported DELs. Herein, we demonstrated a general set of DNA-compatible reactions that enable the preparation of pyrrole-based DNA-encoded libraries in which the DNA tags are linked to the N position of the pyrrole central core. Further diversification could be rapidly incorporated into the pyrrole scaffold by robust iodination and Suzuki coupling reactions.
