  摘要：

  选择性地结合给定蛋白质，然后进行快速化学选择性反应以形成共价缀合物的分子在药物开发中具有实用性。本文设想了一个 1,3,4-恶二唑库，其 2 位被芳基磺酰氟取代，5 位被取代的芳基取代，已知该芳基对转甲状腺素蛋白 (TTR) 的内部甲状腺素结合亚位点具有高亲和力基于结构的设计原理并通过化学合成。当结合在甲状腺素结合位点时，大多数芳基磺酰氟会与 pKa 扰动的 K15 残基发生快速且化学选择性的反应，从而在动力学上稳定 TTR，从而防止已知会导致多发性神经病的淀粉样原纤维形成。结合 t50 范围为 1 至 4 分钟，比甲状腺素结合位点外的水解反应快约 1400 倍。X 射线晶体学证实了预期的结合方向，并揭示了磺酰氟活化导致磺酰胺与 TTR 的连接。一些芳基磺酰氟在血浆中与 TTR 有效形成缀合物。合成的 11 种 TTR 共价动力学稳定剂在缀合时表现出荧光，因此由于发色团的环境敏感荧光而可能具有成像应用。

• Sulfinic Acids and Related Compounds 23. Preparation of Sulfinic Acids by the Reaction of Sulfonyl Halides with Thiols
  作者：Chew Lee、Lamar Field

  DOI：10.1055/s-1990-26884

  日期：——

  The reaction of arene- and alkanesulfonyl halides with p-thiocresol in the presence of triethylamine at - 76°C gives triethylammonium sulfinates, which after acidification afford sulfinic acids of 95-100% purity in yields of 51-92% for 18 typical representatives. The synthesis succeeds in certain instances where conventional reduction with aqueous sodium sulfite fails and in other instances often is superior. The method is rapid, mild, selective, convenient, and general, although a few limitations are reported. Characterizations of the sulfinic acids are effected by titration with aqueous sodium nitrite, by IR and 1H-NMR spectra, by preparation of either a S-benzylthiuronium salt or a p-nitrobenzyl ester, and either by elemental analyses or comparison with reported melting points of the acids and derivatives as appropriate.

  在-76°C下，芳基和烷基磺酰氯与对硫甲酚在三乙胺存在下的反应，生成了三乙铵亚磺酸盐，酸化后得到纯度为95-100%的亚磺酸，对于18个典型代表物的产率为51-92%。在某些情况下，这种合成方法成功地替代了传统的硫酸钠水溶液还原法，并且在其他情况下通常更优。该方法快速、温和、选择性强、方便且具有通用性，尽管也报道了一些局限性。亚磺酸的表征是通过水合亚硝酸钠滴定、红外和氢核磁共振光谱、制备S-苄基硫脲盐或对硝基苄酯，以及元素分析或与报道的酸及其衍生物的熔点进行比较来实现的。
