GW843682X

Research use only, not for human use.

GW843682X is a selective, ATP-competitive inhibitor of PLK1 and PLK3, with IC50s of 2.2 nM and 9.1 nM, respectively, and is also >100-fold selective against ～30 other kinases.

GW843682X is effective on 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, with an IC50 of 0.14 μM. GW843682X (3 μM) causes a strong G2-M arres 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. GW843682X inhibits proliferation of U937 cells with an EC50 of 120 nM. GW843682X (500 nM) in combination with 5 μM VP-16 suppresses 50% of entry into mitosis in U937 cells. GW843682X (0.06-1μM) has inhibitory activities against proliferation of acute leukemia cells, and potentiates the anti-proliferative activity of vincristine. Moreover, GW843682X (0.1-1μM) induces apoptosis of leukemia cells in a dose- and time-dependent manner. GW843682X (0.5-1μM) dephosphorylates Bcl-xl in leukemia cells.
