A screening of natural products using a luciferase assay targeting the Wnt signaling pathway was carried out, and the bioassay-guided fractionation of Excoecaria indica (Euphorbiaceae) collected from Bangladesh afforded three phorbol esters (1 - 3). These compounds exhibited Wnt signal-augmenting effects with 1 causing a 25-fold increase in TCF/β-catenin (TOP) transcriptional activity at 95 nM.
