幽门螺杆菌(HP)是造成急、慢性胃炎的主要致病因素。致病菌粘附于粘膜上皮细胞表面或胃表面的粘膜层。研究发现细菌的粘附作用与细胞表面受体如硫化糖类等有关,这些受体与细菌的结合具有高度的特异性。因此,阻止细菌感染的一个方法就是找到能对抗细菌与糖类受体结合的抑制剂。 Helicobacter pylori (HP) is a major cause of acute and chronic gastritis. The pathogenic bacteria adhere to the mucous layer of the mucosal epithelial cell surface or stomach surface. Studies have found that bacterial adhesion is associated with cell surface receptors such as sulphuric sugars, etc. The binding of these receptors to bacteria is highly specific. Therefore, one way to stop bacterial infections is to find inhibitors that can fight bacterial binding to carbohydrate receptors.
