We describe coumarin derivatives that are non-fluorescent in aqueous buffers and that very selectively bind to transthyretin (TTR) in complex biological environments potently inhibiting TTR amyloidogenesis while also exhibiting sensitive off–on fluorescent sensing of the properly folded quaternary structure of TTR.
