  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.

• Practical Chemoselective Acylation: Organocatalytic Chemodivergent Esterification and Amidation of Amino Alcohols with <i>N</i> ‐Carbonylimidazoles

  DBU-catalyzed esterification: A single esterification product was obtained from a molecule containing primary aniline, alcohol, phenol, secondary amide, and N−H indole groups. These acylation reactions are highly practical as they involve only readily available, inexpensive, and relatively safe reagents; can be performed on a multigram scale; and can be used on carboxylic acids directly by in situ formation

  化学选择性转化是高效有机合成的基石；然而，即使是简单的转化，如酰化反应，要实现这一目标也常常是一个挑战。我们报告说，N-羰基咪唑分别在吡啶鎓离子或 1,8-二氮杂双环 [5.4.0] undec-7-ene (DBU) 存在下能够催化化学发散的苯胺或醇酰化。两种酰化反应都显示出对目标基团的高而广泛的化学选择性。在 DBU 催化的酯化中观察到了前所未有的化学选择性水平：从含有伯苯胺、醇、苯酚、仲酰胺和N的分子中获得单一酯化产物-H吲哚基团。这些酰化反应非常实用，因为它们只涉及容易获得、便宜且相对安全的试剂；可以在多克规模上进行；并且可以通过原位形成酰基咪唑亲电试剂直接用于羧酸。
