Ergosterol peroxide inhibits ovarian cancer cell growth through multiple pathways
Ergosterol peroxide (EP), a sterol derived from medicinal mushrooms, has been reported to exert antitumor activity in several tumor types. However, the role of EP toward ovarian cancer cells has not been investigated. In this study, we analyzed the cytotoxicity of EP in various cell lines representing high-grade serous ovarian cancer and low-grade serous ovarian cancer, respectively. Although E...
متن کاملTransformation of ergosterol peroxide to cytotoxic substances by rat intestinal bacteria.
Ergosterol peroxide (EPO, 1) is a major antitumor sterol produced by edible or medicinal mushrooms. Following oral administration of 1 to rats or anaerobic in vitro incubation of 1 with rat fecal bacteria, three metabolites were detected and their structures were identified to be 5alpha,6alpha-epoxyergosta-8(14),22-diene-3beta,7alpha-diol (M1, 2), 5alpha,6alpha-epoxyergosta-8,22-diene-3beta,7al...

A New Method for the Isolation of Ergosterol and Peroxyergosterol as Active Compounds of Hygrophoropsis aurantiaca and in Vitro Antiproliferative Activity of Isolated Ergosterol Peroxide.
In the present study, ergosterol peroxide and ergosterol were isolated for the first time from fresh fruit bodies of Hygrophoropsis aurantiaca (False Chanterelle). The substances were characterized mainly by spectroscopic methods (¹H-NMR, (13)C-NMR, DEPT-45, DEPT-90, DEPT-135, 2D-NMR). In our study, a new specific thin layer chromatographic method was developed for determination of ergosterol a...
متن کاملErgosterol peroxide, an apoptosis-inducing component isolated from Sarcodon aspratus (Berk.) S. Ito.
Among the lipophilic extracts of seven traditional edible mushrooms, the acetone extract of Sarcodon aspratus markedly inhibited the growth of HL60 human leukemia cells and induced apoptosis after 24 h incubation. The major active component was identified as ergosterol peroxide by NMR and ESI-MS analysis. Ergosterol peroxide completely inhibited growth and induced apoptosis of HL60 cells at a c...
