In-Bead Screening of Hydroxamic Acids for the Identification of HDAC Inhibitors

Katrine Qvortrup, Thomas Eiland Nielsen

Research output: Contribution to journalJournal articleResearchpeer-review


A one bead–one compound screening format is presented. Following solid-phase synthesis on a photolabile linker, library compounds were readily released and screened inside polymer beads. The release of screening compounds was readily controlled by varying photolysis time and light intensity. Dose-response experiments were carried out to effectively distinguish high- and low-affinity ligands. A library containing 55 800 compounds was synthesized and screened in a fluorometric assay, thereby identifying potent HDAC inhibitors with IC50 values in the nanomolar range.
