Tafamidis can be used as a benzoxole derivative that is a transthyretin (TTR) amyloid fibril inhibitors. It is a new drug candidate in the treatment of TTR amyloidosis (caused my misfolding of proteins).
Tafamidis is a potent and selective transthyretin kinetic stabilizer that inhibits the amyloid cascade. It is a drug for the amelioration of transthyretin-related hereditary amyloidosis. It functions by kinetic stabilization of the correctly folded tetrameric form of the transthyretin (TTR) protein and binds selectively and with negative cooperativity to the two normally unoccupied thyroxine-binding sites of the tetramer, and kinetically stabilizes TTR.

Tafamidis binds selectively and with negative cooperativity (K(d)s ~2 nM and ~200 nM) to the two normally unoccupied thyroxine-binding sites of the tetramer, and kinetically stabilizes TTR. Patient-derived amyloidogenic variants of TTR, including kinetically and thermodynamically less stable mutants, are also stabilized by tafamidis binding. The crystal structure of tafamidis-bound TTR suggests that binding stabilizes the weaker dimer-dimer interface against dissociation, the rate-limiting step of amyloidogenesis
