Publication Abstract from PubMed
A new strategy that combines the concepts of fragment-based drug design and dynamic combinatorial chemistry (DCC) for targeting adenosine recognition sites on enzymes is reported. We demonstrate the use of 5'-deoxy-5'-thioadenosine as a noncovalent anchor fragment in dynamic combinatorial libraries templated by Mycobacterium tuberculosis pantothenate synthetase. A benzyl disulfide derivative was identified upon library analysis by HPLC. Structural and binding studies of protein-ligand complexes by X-ray crystallography and isothermal titration calorimetry informed the subsequent optimisation of the DCC hit into a disulfide containing the novel meta-nitrobenzyl fragment that targets the pantoate binding site of pantothenate synthetase. Given the prevalence of adenosine-recognition motifs in enzymes, our results provide a proof-of-concept for using this strategy to probe adjacent pockets for a range of adenosine binding enzymes, including other related adenylate-forming ligases, kinases, and ATPases, as well as NAD(P)(H), CoA and FAD(H2) binding proteins.
