recently found that N-[3-[3-(piperidinomethyl)phenoxyl]propyl]acetamide derivatives with a thioether function showed gastric anti-secretory and gastroprotective activities and that the thioether function (particularly furfurylthio or furfurylsulfinyl) was essential for gastroprotection. In the present study, a series of 2-furfurylthio and 2-furfurylsulfinyl acetamide derivatives were synthesized and
我们最近发现具有硫醚功能的N- [3- [3-(3-哌啶基甲基)苯氧基]丙基]乙酰胺衍生物具有抗胃分泌和保护胃的活性,硫醚功能(尤其是糠基硫基或糠基亚磺酰基)对于胃保护至关重要。在本研究中,合成了一系列2-糠基硫基和2-糠基亚磺酰基乙酰胺衍生物,并评估了其对组胺H2受体的拮抗活性,胃的抗分泌活性和胃保护作用。根据N- [3- [3-(哌啶子基甲基)苯氧基]丙基]乙酰胺的结构,设计了其中3-(哌啶子基甲基)苯氧基部分被连接到叔胺上的多种杂芳族环取代的化合物。丙基被其他碳键取代。讨论了构效关系。在测试的化合物中,2-糠基亚磺酰基-N- [4- [4-(哌啶子基甲基)-2-吡啶基氧基γ]-(Z)-2-丁烯基]乙酰胺是最有效的,其代号为FRG-8813。
