LF3 is a potent inhibitor of canonical Wnt signaling pathway (IC₅₀ < 2 µM ). It can disrupt the interaction between catenin and TCF4. LF3 blocks the expression of a series of Wnt target genes in Wnt-addicted colon cancer cells. It inhibits proliferation of Wnt-addicted colon cancer cells through induction of cell-cycle arrest and also inhibits self-renewal capacity of cancer stem cells (CSCs).
