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
合成2-[((2-吡啶基甲基)亚磺酰基]噻吩并咪唑类化合物,并研究其作为胃H + / K(+)-ATPase的潜在抑制剂。已发现两种可能的噻吩并咪唑系列的[3,4-d]异构体在体外和体内都是有效的胃酸分泌抑制剂。结构活性关系表明,特别是在吡啶部分的4位具有额外的电子要求特性的亲脂性烷氧基,苄氧基和苯氧基取代基与未取代的噻吩并[3,4-d]咪唑结合会导致具有高活性的化合物。良好的化学稳定性。噻吩并[3,4-d]咪唑部分的各种取代方式导致较低的生物活性。选择了七氟丁氧基衍生物萨维拉唑(HOE 731,5d)进行进一步开发,目前正在临床评估中。
