accelerated in a unique binding pocket of serum albumin. We have designed and synthesized a fluorescently activatable coumarin derivative with a benzisoxazole scaffold to enable monitoring of the Kemp elimination reaction in terms of fluorescence change for the first time. We show that this fluorescent sensor can sensitively and selectively quantitate serum albumin in blood samples. It also works in a dry-chemistry
肯普消除反应是众所周知的化学反应,其在蛋白质表面微环境上得到促进,并且特别是在血清白蛋白的独特结合口袋中被高度加速。我们已经设计并合成了具有苯并异恶唑支架的可荧光激活的香豆素衍生物,从而能够首次监测荧光变化方面的Kemp消除反应。我们表明,这种荧光传感器可以灵敏和选择性地定量血液样本中的血清白蛋白。它也可以以干化学形式使用。
