A family of covalent kinetic stabilizer compounds that selectively and covalently react with the prominent plasma protein transthyretin in preference to more than 4000 other human plasma proteins is disclosed. A contemplated compound corresponds in structure to Formula I, below, where the various substituents are defined within, and
reacts chemoselectively with one or two of four Lys-15 ε-amino groups within the transthyretin tetramer. The crystal structure confirms the binding orientation of the compound substructure and the conjugating amide bond. A covalent transthyretin kinetic stabilizer exhibits superior amyloid inhibition potency, compared to a non-covalent counterpart, and inhibits cytotoxicity associated with amyloidogenesis.
本发明揭示了一种共价动力稳定剂化合物家族,它们选择性地和共价地与显著的血浆蛋白转甲状腺素反应,而不是其他4000多种人类血浆蛋白。考虑到的化合物对应于以下公式I的结构,其中各种取代基在内部定义,并与转甲状腺素四聚体内的四个Lys-15 ε-氨基基团之一或两个发生化学选择性反应。晶体结构证实了化合物亚结构和结合酰胺键的结合方向。与非共价对应物相比,共价转甲状腺素动力稳定剂表现出优越的淀粉样抑制效力,并抑制与淀粉样生成相关的细胞毒性。
