Growth inhibition of Helicobacter pylori by a polyamine synthesis inhibitor, methylglyoxal bis(cyclopentylamidinohydrazone)

Lett Appl Microbiol. 1997 Sep;25(3):177-80. doi: 10.1046/j.1472-765x.1997.00198.x.

Abstract

The anti-proliferative effect of methylglyoxal bis(cyclopentylamidino-hydrazone) (MGBCP), a multi-enzyme inhibitor of polyamine biosynthesis, on the growth of Helicobacter pylori was investigated. MGBCP inhibited the cell growth of H. pylori in a dose-dependent manner. The inhibition was partially reversed by the addition of spermidine. Synthesis of macromolecules, DNA, RNA and protein, was inhibited in the spermidine-depleted H. pylori cells. These findings suggest that MGBCP exhibits an anti-proliferative effect on H. pylori by suppression of macromolecule synthesis.
