activity against gastric H+/K(+)-ATPase prepared from rabbit stomach and gastric acid secretions in Heidenhain pouch dogs. Monoalkyl substituents on the nitrogen atom of the aniline moiety markedly inhibited the enzyme activity to the same degree as omeprazole, a representative H+/K(+)-ATPase inhibitor. Most of these compounds, administered at 3 mg/kg i.v. inhibited histamine-stimulated gastric acid secretion
合成了一系列N-取代的2-[((2-咪唑基亚磺酰基)甲基]苯胺(3),并评价了其对家兔胃中制备的胃H + / K(+)-ATPase的生物学活性以及海登海因狗的胃酸分泌。苯胺部分氮原子上的单烷基取代基与奥美拉唑(一种代表性的H + / K(+)-ATPase抑制剂)相同程度地显着抑制酶活性。这些化合物中大多数以3 mg / kg静脉给药抑制组胺刺激的胃酸分泌。这些衍生物在pH 6.0时对酶的抑制活性比在pH 7.4时更强,并且与在pH 5.0时在水溶液中的稳定性明显相关。
