  Transition-state analogues as inhibitors for GABA-aminotransferase

  摘要：

  Our previous calculations on the reaction catalysed by GABA-aminotransferase (GABA-T) have been utilized in this work in order to synthesize a series of reversible inhibitors of this enzyme. The synthesized transition-state analogues and their precursors inhibited GABA-T competitively in both the holoenzyme and apoenzyme at 10(-3) and 10(-5) M, respectively. In the case of the holoenzyme, the transition-state analogue series (the conformationally restricted series) gave a significant increase in inhibition values over the open (less conformationally restricted) series.

  3-benzoxazine and 3,4-dihydro-1,3-pyridooxazine derivatives was synthesized, and the hydrolysis of the derivatives was studied with proton nuclear magnetic resonance spectroscopy. The oxazine derivatives underwent various degrees of hydrolysis when H2O was added to dimethyl sulfoxide solutions of the compounds. The rates and extents of decomposition of the oxazine ring systems depended on the electronic effects

  合成了一系列的3,4-二氢-1,3-苯并恶嗪和3,4-二氢-1,3-吡啶并恶嗪衍生物，并利用质子核磁共振波谱研究了这些衍生物的水解。当将H 2 O加入到化合物的二甲基亚砜溶液中时，恶嗪衍生物经历了不同程度的水解。恶嗪环系统分解的速率和程度取决于分子内取代基的电子效应。对恶嗪分解期间产生的质子核磁共振谱以及恶嗪衍生物的稳定性趋势的研究表明在水解机理中形成了中间体。
