Objective: The objective of the study was to investigate the inhibitory activity of polyisoprenoids from Nypa fruticans leaves on the expression of cyclooxygenase 2 (COX-2) against colon cancer cells.

Methods: Anticancer activity performed was tested by dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method on colon cancer cell WiDr. The expression of COX-2 was observed by the immunocytochemistry method.

Result: Polyisoprenoids from N. fruticans leaves exhibit anticancer activity on WiDr cells through inhibition of COX-2 expression with IC50 180.186±7.16 μg/ml.

Conclusions: This study showed that polyisoprenoids from N. fruticans leaves promise chemopreventive agents for colon cancer through COX-2 inhibition.

Keywords: Cytotoxic, Polyisoprenoids, Nypa fruticans, Cyclooxygenase-2.
