  Kinetic Stabilization of an Oligomeric Protein by a Single Ligand Binding Event

  摘要：

  Protein native state stabilization imposed by small molecule binding is an attractive strategy to prevent the misfolding and misassembly processes associated with amyloid diseases. Transthyretin (TTR) amyloidogenesis requires rate-limiting tetramer dissociation before misassembly of a partially denatured monomer ensues. Selective stabilization of the native TTR tetramer over the dissociative transition state by small molecule binding to both thyroxine binding sites raises the kinetic barrier of tetramer dissociation, preventing amyloidogenesis. Assessing the amyloidogenicity of a TTR tetramer having only one amyloidogenesis inhibitor (1) bound is challenging because the two small molecule binding constants are generally not distinct enough to allow for the exclusive formation of (TTRI)-I-. in solution to the exclusion of (TTRI2)-I-. and unliganded TTR. Herein, we report a method to tether one fibril formation inhibitor to TTR by disulfide bond formation. Occupancy of only one of the two thyroxine binding sites is sufficient to inhibit tetramer dissociation in 6.0 M urea and amyloidogenesis under acidic conditions by imposing kinetic stabilization on the entire tetramer. The sufficiency of single occupancy for stabilizing the native state of TTR provides the incentive to search for compounds displaying striking negative binding cooperativity (e.g., K-d1 in nanomolar range and K-d2 in the micromolar to millimolar range), enabling lower doses of inhibitor to be employed in the clinic, mitigating potential side effects.

  ketosulfoxides 7 and 8 depending on the nature of the substituent at C3 and on the reaction conditions. The normal fragmentation of dioxetanes 2 to 4 competes with an intramolecular oxygen transfer to ring sulfur, which leads to 7 and 8, presumably via the labile epoxides 5. This new pathway is promoted by electron-withdrawing groups at C3 and, for unsubstituted and monosubstituted amide derivatives 1h and 1i

  单线态氧与各种取代的氧杂环丁烷1的反应产生二羰基化合物4和/或酮亚砜7和8，这取决于C 3上取代基的性质和反应条件。二氧环乙烷2到4的正常断裂与分子内的氧转移竞争成环硫，这大概是通过不稳定的环氧化物5导致的7和8。这种新的途径是由C3上的吸电子基团促进的，对于未取代的和单取代的酰胺衍生物1h和1i分别通过溶剂呈碱性。化学实验支持7为环氧化物5的中间体，而对于8为环氧化物的结论并不明确。但是，后者的形成似乎受到极性溶剂和C2上的阳离子稳定基团（如苯基或甲基）的帮助。

  [formula: see text] Single oxygen oxygenation of 5,6-dihydro-1,4-oxathiins substituted at C-3 with an electron-withdrawing group leads stereoselectively to ketosulfoxides 5 and 6, instead of the expected dicarbonyl compounds 3. A mechanism involving an unprecedented intramolecular rearrangement of the corresponding dioxetanes 2 is proposed.
