Abstract

Twelve analogues of diclofenac (1), a nonsteroidal antiinflammatory drug and known inhibitor of transthyretin (TTR) amyloid formation, were prepared and evaluated as TTR amyloid formation inhibitors. High activity was exhibited by five of the compounds. Structure-activity relationships reveal that a carboxylic acid is required for activity, but changes in its position as well as the positions of other substituents are tolerated. High-resolution X-ray crystal structures of four of the active compounds bound to TTR were obtained. These demonstrate the significant flexibility with which TTR can accommodate ligands within its two binding sites.
