This study investigated the influences of lansoprazole (AG1749), a proton pump inhibitor (PPI), and its active derivative (AG2000) on Candida albicans growth and the anti-Candida activity of macrophages. Under concentration of 100 microM, AG1749 and AG2000 had no effect on Candida growth. Murine peritoneal macrophages inhibited the growth of C. albicans in vitro. AG2000 suppressed the anti-Candida activity of macrophages dose-dependently, but AG1749 didn't. The suppressing activity of AG2000 for macrophages was neutralized by adding a SH-compound (L-cysteine) in the medium. This suggests that AG2000 may suppress macrophage function in a similar manner with inhibition of proton pump through binding to SH-molecules. When macrophages were preincubated with AG2000 for 1 hr and washed, their anti-Candida activity remained to be partially inhibited for 14 hrs. These results were discussed in relation to the pathogenesis of esophageal candidiasis.
