Background:

Wnt-C59 is a selective inhibitor of Wnt signaling with IC50 value of 74 pM [1].

Wnt signaling pathways are a group of signal transduction pathways made of proteins and play an important role in passing signals from outside of a cell through cell surface receptors to the inside of the cell [1, 2].

Wnt-C59 is a potent Wnt inhibitor and has a different selectivity with the reported Wnt inhibitor crizotinib. When tested with HT1080 and Hela cells, Wnt-C59 showed inhibition on activation of a multimerized TCF-binding site driving luciferase mediated by Wnt3A by completely abrogating Wnt secretion [1]. In 5 human CC cell lines CC-LP-1, SUN-1079, WITT-1, SNU-1196, and CC-SW-1, Wnt-C59 treatment decreased cell viability, reduced cell proliferation and increased cell apoptosis by inhibiting Wnt signaling [2].

In C57/BL6 mice model transplanted with fragments from 2 independent primary MMTV-WNT1 tumors, oral administration of Wnt-C59 (10 mg/kg/d) for 17 days significantly arrested tumor growth and decreased tumor weights after sacrificing mice [1]. When tested with CD1 nude mice model with CC cell lines (CC-LP-1 and CC-SW-1) subcutaneous xenograft into the flanks, administration ofWnt-C59 inhibited cell growth and increased cell apoptosis compared with control group [2].
