| Bioactivity | Tafamidis is a potent and selective transthyretin (TTR) stabilizer, shows comparable potency and efficacy to the mutumant homotetramers V30M-TTR, V122I-TTR and wild type WT-TTR, with EC50s of 2.7-3.2 μM. Tafamidis inhibits amyloidogenesis[1]. | ||||||||||||
| Target | EC50: 2.7-3.2 μM (TTR) | ||||||||||||
| Invitro | Tafamidis binds selectively and with negative cooperativity (Kds ∼2 nM and ∼200 nM) to the two normally unoccupied thyroxine-binding sites of the tetramer, and kinetically stabilizes TTR[1].Tafamidis (0-7.2 μM) dose-dependently inhibits WT-TTR amyloidogenesis after treatment for 72 hours at a pH of 4.4-4.5[1]. | ||||||||||||
