  格氏试剂介导的酰基亚硝基蒽Cyccloadduct转化为硝基

  摘要：

  酰基亚硝基化合物和9,10-二甲基蒽衍生物的分子内杂Diels-Alder环加合物被制备为潜在的硝酰基（HNO）供体。该化合物在任何测试条件下均不释放HNO。用过量的MeMgCl处理该环加合物导致形成硝酮，其结构通过X射线晶体学证实。MeMgCl充当亲核试剂，强碱和路易斯酸的机理可能解释了该产物的形成。

  A Nitroxyl Synthase Catalytic Antibody

  摘要：

  An antibody raised against acridinium hapten 1 is shown to catalyze the retro Diels-Alder reaction of the anthracene-HNO cycloadduct 2 to release anthracene 4 and nitroxyl (HNO). Nitroxyl is oxidized to nitric oxide (NO) in the presence of superoxide dismutase. Since the enzyme superoxide dismutase is ubiquitous in vivo, this catalytic antibody system may be equivalent to NO-synthase. Antibody catalysis is triggered by recognition of the phenyl rings in hapten 1 at an angle near that of the transition state of the retro Diels-Alder reaction of 2. Acridinium hapten 1 is in chemical equilibrium with its conjugate Lewis base 9-hydroxyacridane 1-OH (pK similar to 8.2). Catalytic antibody 9D9 (K-M(2) = 100 mu M, k(cat) = 0.07 min(-1), k(uncat) = 3 x 10(-4) min(-1)) is the result of an heterologous immunization and binds both 1 (K-i = 16.6 mu M at pH 6.1) and 1-OH (K-i = 0.9 mu M at pH 9.0). The more tightly bound neutral conjugate base 1-OH probably represents a more accurate mimic of the transition state of the retro Diels-Alder process.

  A series of eleven immunizations against transition-state analogs were carried out to improve the catalytic Properties of Ab 9D9, a catalytic antibody that catalyzes a fluorogenic retro-Diels-Alder reaction liberating nitroxyl. By a direct fluorescence assay of cell-culture supernatant, eight new hybridoma cell lines producing catalytic antibodies for the reaction were readily identified among more than 14000 individual samples. Our results demonstrate that early catalysis screening by fluorescence allows an efficient survey of large antibody libraries, and may lead to rapid and significant improvement in catalysis.
