Zolucatetide (FOG-001; I-66) is a potent β-catenin inhibitor with an IC50 of β-catenin and T-cell factor (TCF) transcription factor interaction. Zolucatetide inhibits cell proliferation and induces cell cycle arrest in target cells. Zolucatetide exhibits anti-tumor efficacy in mice bearing COLO320DM colon cancer cell (with APC, TP53 mutations) xenografts. Zolucatetide can be used for the study of colon cancer[1].
