Current research interests include screening biological and cytotoxic activities of crude extracts and isolated compounds from a variety of indigenous plants with the aim of searching for potent compounds against some (untreated) cancers. This activity is undergoing in collaboration with the Department of Chemistry. In addition of searching new potent anticancer compounds from natural sources, we also evaluate therapeutic potential of some traditional herbal medicines as a drug discovery tool to identify drug leads, particularly for aging intervention. One current research project is focused on the development of an indigenous herb, Wan chak motluk or Curcuma comosa Roxb as a nutraceutical for health promotion in peri- and postmenopausal women. Several pharmacological activities of the crude extracts from C. comosa and its isolated compounds, diarylheptanoids are evaluating for treatment unpleasant menopause symptoms. Both estrogenic and anti-estrogenic in reproductive tissues and non-reproductive tissues are characterized. Their actions at molecular targets are investigated in both in vitro and in vivo models.
