dc.description.abstractEthnopharmacological relevance: Curcuma zedoaria Roscoe (Zingiberaceae), also known as white turmeric or zedoaria, has been used in Ayurveda and traditional Chinese medicine to treat various cancers, and it possesses several sesquiterpenoid compounds. Objective: This study aimed to evaluate the therapeutic effects of a methanolic (MeOH) extract of C. zedoaria rhizomes, as well as its active constituents, against gastric cancer, which is a frequently diagnosed cancer in South Korea. Materials and methods: Repeated column chromatography, together with semi-preparative HPLC purification, was used to separate the bioactive constituents from the C. zedoaria MeOH extract. The cytotoxic effects of the C. zedoaria MeOH extract and its active compounds were measured in human gastric cancer AGS cells. Expression of proteins related to apoptosis was evaluated using Western blotting analysis. Results: The MeOH extract of C. zedoaria rhizomes exerted a cytotoxic effect on AGS cells (IC50: 96.60 +/- 4.87 mu g/mL). Based on the bioactivity-guided fractionation for antiproliferative activity, a chemical investigation of the MeOH extract led to the isolation of five sesquiterpenes including isoprocurcumenol (1), germacrone (2), curzerenone (3), curcumenol (4), and curcuzedoalide (5). Among these, curcuzedoalide demonstrated the strongest effect in suppressing gastric cancer cell proliferation in a dose-dependent manner with an IC50 value of 125.11 +/- 2.77 mu M. Western blotting analysis showed that curcuzedoalide inhibited AGS human gastric cancer cell viability by activating caspase-8, caspase-9, caspase-3, and PARP, which contributed to apoptotic cell death in AGS human gastric cancer cells. Conclusion: These data indicate that curcuzedoalide contributed to the cytotoxicity of C. zedoaria by activating the cleavage of caspases and PARP, which are representative markers for apoptosis. Therefore, curcuzedoalide is. a positive candidate for the development of novel chemotherapeutics.-
