Poloxin-2 is a specific inhibitor of Polo-like Kinase 1 (PLK1), effectively inducing mitotic arrest in HeLa cells with an EC50 of approximately 15 μM. It targets the Polo-box domain to disrupt protein-protein interactions, facilitating its application in cancer research. The hydrophobic tag (HT) conjugated form, Poloxin-2HT, exhibits enhanced potency by promoting selective degradation of the PLK1 protein, resulting in increased apoptosis and reduced cell viability. This highlights the potential of hydrophobic tags as a novel strategy for targeting disease-associated proteins.
