Notes: Poloppin is an inhibitor of the protein-peptide interaction between polo-like kinase 1 (Plk1) and the Plk1-binding phosphopeptide (IC50 = 26.9 µM).{64930} It induces mitotic arrest in HeLa cells (EC50 = 29.9 µM). Poloppin inhibits cell growth in murine pancreatic organoids expressing mutant K-Ras (GI50s = 22.92-28.39 µM).
