Abstract

In the present study, the effects of a Thai Traditional herbal recipe called “trikatu” on a cholangiocarcinoma cell line were explored. This classic Ayurvedic remedy is an herbal blend of dried powdered Piper nigrum L., Piperaceae, Piper retrofractum Vahl, Piperaceae, and Zingiber officinale Roscoe, Zingiberaceae. The HPLC quantitative analysis of the active compounds in the formulation were investigated. Total flavonoid, total phenolic contents, and antioxidant assay were performed. Cytotoxic study was determined using sulforhodamine B assay. Cell cycle arrest and apoptosis were evaluated by propidium iodide and annexin V-FITC/PI staining. Western blot analysis was done to evaluate protein expression. Above all, HPLC analyses revealed that the major active constituent was piperine. The result showed that “trikatu” significantly inhibited the migration of cholangiocarcinoma cell which also induced cell cycle arrest on G2 phase via a decrease in the expression of CDK2 and p53, and upregulation of p21and p27. “Trikatu” showed antioxidant capacity, expressed high piperine content, and had anti-cell viability and anti-proliferation effect on cholangiocarcinoma in vitro.
