| Abstract: | The effect of activated lansoprazole (AG 2000), a novel benzimidazole proton pump inhibitor, against hypha formation of Candida albicans was examined in hypha-forming medium pH 7 (HFM7) after 20 h. AG 2000, at 50-800 microM, did not inhibit germ tube formation. However, it inhibited elongation of germ tubes to form hyphae and favored conversion of germ tubes to resume yeast growth at concentrations of > or =200 microM. Pre-treatment of AG 2000 with a sulfhydryl reagent (1:1), such as 2-mercaptoethanol. blocked the inhibitory property of AG 2000 on hypha formation. |
