discover a novel potent potassium-competitive acid blocker (P-CAB) agent, a series of 5-methyl-2,4,5,6-tetrahydropyrrolo[3,4–c]pyrazole derivatives were synthesized, and their H+/K+-ATPase inhibitory activities and inhibitory action on histamine-stimulated gastric acid secretion in rats were evaluated. Among the compounds synthesized, compound 3′-((3-(2-fluorophenyl)-5-methyl-5,6-dihydropyrrolo[3,4–
为了发现一种新型强效钾竞争性酸阻滞剂 (P-CAB),合成了一系列 5-甲基-2,4,5,6-四氢吡咯并[3,4- c ]吡唑衍生物,并对其评价H + /K + -ATP酶抑制活性和对大鼠组胺刺激的胃酸分泌的抑制作用。在合成的化合物中,化合物3'-((3-(2-氟苯基)-5-甲基-5,6-二氢吡咯并[3,4- c ]吡唑-2(4H)-基)甲基)-[1, 1'-联苯]-3-甲酰胺不仅表现出有效的H + /K + -ATPase抑制活性,而且在体内也表现出有效的抑制作用关于组胺刺激的胃酸分泌。此外,该先导化合物在大鼠中表现出良好的口服药代动力学特性,作为一种新型 P-CAB 药物值得进一步研究。
