    摘要:
    [(吡啶基甲基)亚磺酰基]苯并咪唑1(PSBs)是一类高度有效的抗分泌(H +,K +)-ATPase抑制剂,需要通过酸激活才能形成其活性成分,即环亚磺酰胺4。(H + ,K +)-ATPase在体内仅在低pH时会产生非选择性的亲硫基4,从而避免了与体内其他巯基的相互作用。进行酸催化转化的倾向取决于2形成中所涉及的官能团的亲核/亲电性质,因为该步骤既决定速率又取决于pH。这项研究的目的是鉴定在具有酸性pH值的刺激胃腺中具有高(H +,K +)-ATPase抑制活性的化合物,但在体外pH值(Na +,K +)-ATPase抑制活性。仔细研究了所有衍生物中存在的吡啶4-甲氧基取代基侧面的取代基的关键影响。3-甲氧基的引入使得抑制剂具有与奥美拉唑和兰索拉唑相似的高效力组合,但是增加了稳定性。这些研究的结果是,化合物1a(INN top托拉唑)被选作候选药物,目前正在进行III期临床研究。

    2-[(2-Pyridylmethyl)sulfinyl]thienoimidazoles were synthesized and investigated as potential inhibitors of gastric H+/K(+)-ATPase. The [3,4-d] isomers of the two possible thienoimidazole series were found to be potent inhibitors of gastric acid secretion in vitro and in vivo. Structure-activity relationships indicate that especially lipophilic alkoxy, benzyloxy, and phenoxy substituents with additional

  • Structure-Activity Relationship of Omeprazole and Analogs as Helicobacter pylori Urease Inhibitors
    作者:Thomas C. Kuehler、Jan Fryklund、Nils-ke Bergman、Jessica Weilitz、Adrian Lee、Haakan Larsson
    DOI:10.1021/jm00025a008
    日期:1995.12
    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.
