ENZYMATIC AND STRUCTURAL CHARACTERIZATION OF NON PEPTIDE LIGAND CYCLOPHILIN COMPLEXES
Overview
Piperidine ligands are described that provide the first examples of, non-peptidic ligand structures for the cyclophilin family of proteins., Crystal structures of two ligand complexes are compared with the, unliganded protein and show ligand-induced changes in side-chain, conformation and water binding. A peptidylprolyl cis-trans-isomerase assay, showed the dissociation constants of the two ligands to be 320 and 25 mM., This study also provides the first published data for both enzymatic, activity and three-dimensional structure for any protein-ligand complex, that binds with a high-millimolar dissociation constant. The structures, may be of relevance in the field of drug design, as they suggest starting, points for the design of larger tighter-binding analogues.
