A thymoquinone derivative, non-ATP competitive Polo-like Kinase 1 (Plk1) inhibitor specifically targeting the polo-box domain (PBD) of Plk1 (IC50)=4.8uM. Reduces both chromosome and kinetochoral localization of Plk1, induces chromosome congression defects , mitotic arrest in prometaphase, and apoptosis in HeLa cells at 25uM. Exhibits anti-proliferative effects in a range of cancer cell lines, and in a mouse Xenograft model involving HeLa and MDA-MB-231 cells at 40mg/kg.
