Abstract

Lonicerae flos aqua-acupuncture solution (LFAS) and Lonicerae flos water-extracted solution (LFWS) were prepared and tested for chemopreventive potentials. Three biomarkers [quinone reductase (QR), ornithine decarboxylase (ODC), glutathione(GSH)] were used to test chemopreventive potential of LFAS. LFAS was potent inducer of QR activity in Hepa1c1c7 murine hepatoma cells, whereas LFWS is less potent. LFAS and LFWS were also induced QR activities in cultured human hepatoma Hep3B cells. The effect of LFAS and LFWS were tested on the growth of Acanthamoeba castellanii. Proliferation of Acanthamoeba castellanii was inhibited by LFAS and LFWS at concentrations of $0.1{\times},\;0.5{\times}\;1{\times},\;and\;3{\times}.$ In addition, GSH levels were increased about 2-fold with LFAS and 1.5-fold with LFWS in cultured murine hepa1c1c7 cells. LFAS and LFWS were also shown to increase GSH levels in human Hep3B cells. These results suggest that LFAS has chemopreventive potential by inducing QR activity, inhibition of ODC activity and increasing GSH levels.
