BI 2536 is a potent, ATP-competitive, well tolerated and highly specific human polo-like kinase 1 (PLK1) inhibitor with IC value of 0.83 nM, which shows 1000-fold selectivity against other kinases [1].
BI 2536 has been demonstrated to suppress cell growth and colony formation, it has been shown to induce mitotic arrest at G2/M phase and apoptosis in human cervical adenocarcinoma cell line HeLa [2].
BI 2536 has shown to have the effect of inhibiting cell proliferation in more than 20 tumor cell lines with half maximal effective concentration (EC50) values ranging from 2–25 nM. In vivo, multiple studies in xenograft models of human carcinoma have shown the anti-tumor activity of BI 2536 when the drug was intravenously administered 1-2 times every week [1].
