This study investigated the interaction between the chemical constituents of a medicinal plant and human breast cancer cells, and found that some compounds exhibited similar activity to commonly used drugs, suggesting the potential of this plant in combating breast cancer.
Breast cancer is the most devastating disease for women. There is a great demand for new sources to treat this disease. Medicinal plants are an indispensable source of bioactive compounds with wide range of pharmacological activities. In-vitro cytotoxic activity of Otostegia fruticosa methanolic extract against human breast cancer was studied using MCF-7 cell line. The extract showed mildly potent activity (IC50 = 51 +/- 9.836 mu g/mL) in comparison to the standard anticancer doxorubicin (IC50 = 7.467 +/- 1.05 mu g/mL). Potential compounds responsible for activity have been identified using Molecular Operating Environment (MOE) module on the major compounds detected by HPLC-MS/MS technique against estrogen alpha receptor (ER alpha+: PDB ID 2JF9). 3,5-di-O-dicaffeoylquinic acid, hyperoside and rutin showed similar binding and antagonistic interaction with the estrogen alpha receptor as tamoxifen in several poses. The retrieved results confirm that we can add this plant to a powerful arsenal that combats this insidious disease.
