  Structure-Activity Relationship of Omeprazole and Analogs as Helicobacter pylori Urease Inhibitors

  摘要：

  Helicobacter pylori urease belongs to a family of highly conserved urea-hydrolyzing enzymes. A common feature of these enzymes is the presence of two Lewis acid nickel ions and a reactive cysteine residue in the active site. The H+/K(+)-ATPase inhibitor omeprazole is a prodrug of a sulfenamide which covalently modifies cysteine residues on the luminal side of the H+/K(+)-ATPase of gastric parietal cells. Omeprazole and eight analogues were selected based on their chemical, electronic, and kinetic properties, and each was incubated with viable H. pylori in phosphate-buffered saline at pH 7.4 for 30 min, after which 100 mM urea was added and the amount of ammonia formed analyzed after a further 10 min. Inhibition between 0% and 100% at a 0.1 mM concentration was observed for the different analogues and could be expressed as a function of the pKa-value of the pyridine, the pKa-value of the benzimidazole, the overall lipophilicity, and, most importantly, the rate of sulfenamide formation, in a quantitative structure-activity relationship. The inhibition was potentiated by a lower pH (favoring the formation of the sulfenamide) but abolished in the presence of beta-mercaptoethanol (a scavenger of the sulfenamide). Structural analogues incapable of yielding the sulfenamide did not inhibit ammonia production. Treatment of Helicobacter felis-infected mice with 230 mumol/kg flurofamide b.i.d. for 4 weeks, known to potently inhibit urease activity in vivo, as a means of eradicating the infection, was tested and compared with the effect of 125 mumol/kg omeprazole b.i.d. for 4 weeks. Neither treatment proved efficacious.

  relevant diazoles. Our method can deliver both free amines and monoalkyl amines allowing access to unsymmetrical, selectively monoalkylated benzimidazoles and benzotriazoles. As well as providing concise access to valuable ortho-phenylenediamines, this work demonstrates the potential for utilizing noncovalent interactions to control positional selectivity in radical reactions.

  直接从 C-H 键形成芳烃 C-N 键非常重要，最近通过自由基机制实现这一目标的方法得到了快速发展，通常涉及反应性N中心自由基。与这些进步相关的一个主要挑战是区域控制，在大多数协议中获得了区域异构产品的混合物，限制了更广泛的应用。我们设计了一个系统，该系统利用阴离子底物和进入的自由基阳离子之间有吸引力的非共价相互作用，以将后者引导到芳烃邻位。阴离子底物采用氨基磺酸盐保护的苯胺的形式，氨基化后氨基磺酸盐基团的伸缩裂解直接导致邻位-苯二胺，一系列与药用相关的二唑的关键组成部分。我们的方法可以提供游离胺和单烷基胺，从而可以获得不对称的、选择性单烷基化的苯并咪唑和苯并三唑。除了提供对有价值的邻苯二胺的简洁访问外，这项工作还证明了利用非共价相互作用来控制自由基反应中的位置选择性的潜力。
