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.
我们描述了这样一类香豆素衍生物:它们在含水缓冲液中不具荧光,但能在复杂的生物环境中高度选择性地与转运甲状腺素(TTR)结合,强力抑制TTR淀粉样蛋白生成,同时还能灵敏地通过荧光"关闭-开启"机制感知正确折叠的四级结构TTR。
