GW843682X 是 PLK1 和 PLK3 的特异性和 ATP 竞争性抑制剂，IC50 分别为 2.2 nM 和 9.1 nM。

GW843682X is a selective and ATP-competitive inhibitor of PLK1 and PLK3 (IC50s = 2.2 nM and 9.1 nM).

GW843682X (500 nM) in combination with 5 μM VP-16 suppresses 50% of entry into mitosis in U937 cells. GW843682X inhibits the proliferation of U937 cells with an EC50 of 120 nM[1]. GW843682X (0.06-1 μM) has inhibitory activities against the proliferation of acute leukemia cells and potentiates the anti-proliferative activity of vincristine. GW843682X (0.1-1 μM) induces apoptosis of leukemia cells in a dose- and time-dependent manner. GW843682X (0.5-1 μM) dephosphorylates Bcl-xl in leukemia cells[2]. GW843682X is effective in inhibition of growth of tumor cells, with IC50s of 0.41, 0.57, 0.11, 0.38, and 0.70 μM for A549, BT474, HeLa, H460 and HCT116 cell lines. GW843682X dose-dependently inhibits PLK1 phosphorylation of Ser15-p53 (IC50 = 0.14 μM). GW843682X (3 μM) causes strong G2-M arrest in HDF cells and H460 cells after treatment for 24, 48, and 72 h. GW843682X (5 μM) leads to apoptosis in H460 cells instead of HDF cells[3].
