The motility of Helicobacter pylori was maximum at 37 degrees C and at pH 6. A newly developed proton pump inhibitor, rabeprazole (RPZ), and its thioether derivative (RPZ-TH) markedly inhibited the motility of H. pylori. The concentrations of the drug necessary to inhibit 50% of the motility were 0.25, 16, 16, and >64 microgram/ml for RPZ-TH, RPZ, lansoprazole, and omeprazole, respectively. No such inhibitory effects were observed with H(2) blockers or anti-H. pylori agents. The motilities of Campylobacter jejuni and C. coli-but not those of Vibrio cholerae O1 and O139, Vibrio parahaemolyticus, Salmonella enterica serovar Typhimurium, and Proteus mirabilis-were also inhibited. Prolonged incubation with RPZ or RPZ-TH inhibited bacterial growth of only H. pylori, except for a turbid colony mutant. The results indicate that RPZ and RPZ-TH have a characteristic inhibitory effect against the motility of H. pylori (spiral-shaped bacteria), which is distinguished from that against bacterial growth.
幽门螺杆菌的运动性在37摄氏度和pH值为6时最强。一种新开发的质子泵抑制剂雷贝拉唑(RPZ)及其硫醚衍生物(RPZ-TH)显著抑制幽门螺杆菌的运动性。抑制50%运动性所需的药物浓度,RPZ-TH、RPZ、兰索拉唑和奥美拉唑分别为0.25、16、16和>64微克/毫升。H2受体阻滞剂或抗幽门螺杆菌药物未观察到此类抑制作用。空肠弯曲菌和大肠弯曲菌的运动性——但霍乱弧菌O1和O139、副溶血性弧菌、肠炎沙门氏菌鼠伤寒血清型和奇异变形杆菌的运动性未受抑制——也受到抑制。用RPZ或RPZ-TH长时间孵育仅抑制幽门螺杆菌的细菌生长,但有一种浑浊菌落突变体除外。结果表明,RPZ和RPZ-TH对幽门螺杆菌(螺旋形细菌)的运动性具有特征性抑制作用,这与对细菌生长的抑制作用不同。
