2′-piperidin)-1-one derivatives, which could occupy two important lipophilic pockets (described as LP-1 and LP-2) of H+,K+-ATPase and can strongly bind to the K+-binding site, were designed based on a docking model. Among the compounds synthesized, compound 4d showed a strong H+,K+-ATPase-inhibitory activity and a high stomach concentration in rats, resulting in potent inhibitory action on histamine-stimulated
为了发现一种比现有质子泵抑制剂更有效的胃分泌药,新型3,4-二氢-1 H-螺(萘-2,2'-哌啶)-1-酮衍生物可能占据两个重要的位置基于对接模型设计了H +,K + -ATPase的亲脂性口袋(称为LP-1和LP-2),它可以与K +-结合位点牢固结合。在合成的化合物中,化合物4d在大鼠中显示出强大的H +,K + -ATPase抑制活性和高胃浓度,从而对组胺刺激的大鼠胃酸分泌产生有效的抑制作用。此外,4d对大鼠的组胺刺激的胃酸分泌具有显着的抑制作用,给药后起效迅速,作用持续时间适中。这些发现可能会导致对钾竞争性酸阻滞剂药物设计的新见解。
