According to a study published by "Medical oncology (Northwood, London, England)", a chamuangone-enriched extract (CEE) was developed from the leaves of the Thai vegetable Garcinia cowa. This extract was quantitatively standardized by HPLC to contain 73.0 ± 2.0% w/w chamuangone. In vitro studies showed that CEE at a concentration of 10 µg/mL inhibited MCF-7 cell growth and migration while inducing apoptosis and modulating markers like p53, Bcl-2, MMP-2, MMP-9, IL-6, and TNF-α. In vivo studies demonstrated that CEE at 100 mg/kg bodyweight significantly inhibited tumor growth and decreased the expressions of BC Man markers in tumor and lung tissues. These findings support the potential medicinal and protective use of CEE for mitigating the effects of breast cancer and metastasis.
