    We demonstrate a fragment-based lead discovery method that combines site-directed ligand discovery with dynamic combinatorial chemistry. Our technique targets dynamic combinatorial screening to a specified region of a protein by using reversible disulfide chemistry. We have used this technology to rapidly identify inhibitors of the drug target Aurora A that span the purine-binding site and the adaptive pocket of the kinase. The binding mode of a noncovalent inhibitor has been further characterized through crystallography.
