RESUMEN
Prostate cancer remains one of the leading health issues without a fully effective treatment. Medicinal plants are one of the primary sources of compounds for treating numerous ailments. In this sense, the Oenothera genus contains metabolites with antiproliferative activity on cancer cells. For this, the study aimed to explore the antiproliferative activity of its extracts against prostate cancer and identify its metabolites (under metabolomics analyses) associated with anticancer and/or antiproliferative properties. For this reason, a LC-MS/MS-based metabolomic analysis was performed to demonstrate the possible metabolites present in O. rosea. In addition, the antiproliferative activity of different extracts in the human prostate cancer cell line DU145 was evaluated. All extracts have antiproliferative effects on DU145 cells at 72 h, with moderate activity being the best ethanolic either 48 or 72 h. Finally, by LC-MS/MS-based metabolomics, 307 compounds from aqueous, methanolic, ethanolic, and ethyl acetate extracts from which 40 putative metabolites identified were organized as anti-inflammatory, anticancer, and/or antiproliferative activities according to previously reported. These results provide evidence that O. rosea could be used as an antiproliferative agent due to its chemical contents used as polypharmacy with low concentration levels.
