• Stability of Boronic Esters to Hydrolysis: A Comparative Study
  作者：Raffaella Bernardini、Ambrogio Oliva、Alessandro Paganelli、Ernesto Menta、Mario Grugni、Sergio De Munari、Luca Goldoni

  Boronic esters are key intermediates in the synthesis of biologically active compounds such as thrombin and proteasome inhibitors. However, they have low hydrolytic stability both during synthetic reactions and in biological media. We report the preparation of several boronic esters and a comparative study of their stability to hydrolysis vs. the corresponding pinanediol boronic esters, which are among the most hydrolytically stable. We discovered that the boronic esters derived from (1,1′-bicyclohexyl)-1,1′-diol are the most stable among those examined.

  硼酸酯是合成生物活性化合物（如凝血酶和蛋白酶体抑制剂）的关键中间体。然而，它们在合成反应过程中以及在生物介质中均表现出较低的水解稳定性。我们报道了多种硼酸酯的制备及其与相应的水解稳定性较高的二氢二醇硼酸酯的稳定性对比研究。我们发现，由(1,1′-双环己基)-1,1′-二醇衍生的硼酸酯在所研究的样品中水解稳定性最高。

  The development of potent, orally bioavailable, and selective series of 5-amino-3-hydroxy-N(1-hydroxypropane-2-yl)isothiazole-4-carboxamidine inhibitors of MEK1 and MEK-2 kinase is described. Optimization of the carboxamidine and the phenoxyanifine group led to the identification of 55 which gave good potency as in vitro MEK1 inhibitors, and good oral exposure in rat.
