J. Piotrowski et al., INHIBITION OF HELICOBACTER-PYLORI UREASE ACTIVITY BY EBROTIDINE, Biochemistry and molecular biology international, 37(2), 1995, pp. 247-253
Helicobacter pylori is considered a primary factor in the pathogenesis
of gastric disease, and the successful mucosal colonization is linked
to its urease activity. In this study, we assessed the effect of anti
ulcer agent, ebrotidine, on the in vitro activity of H. pylori urease.
The results of assays showed a dose-dependent inhibition of the ureas
e activity. A maximum inhibition (77%) in H. pylori urease activity oc
curred at 2.1 mu M ebrotidine. A known H-2-blocker, ranitidine, in a p
arallel experiment gave a maximal inhibition of 73% at a considerably
higher concentration (6.4 mu M). The results demonstrate that ebrotidi
ne with its combined acid suppressant and anti-H. pylori activities of
fers an excellent choice in the treatment of H. pylori associated gast
ric disease.
