Wortmannin (KY 12420)Wortmannin (KY 12420, SL-2052, BRN 0067676, NSC 627609) is the first described PI3K inhibitor with IC50 of 3 nM in a cell-free assay, with little selectivity within the PI3K family. Wortmannin blocks autophagosome formation and potently inhibits DNA-PK/ATM with IC50 of 16 nM and 150 nM in cell-free assays. Wortmannin also inhibits PLK1 activity. |
![]() ![]() L3.6pl cells at 6,000 cells per well were incubated in MEM with 5% FBS in triplicate in a 96-well culture plate and then treated alone with 5 umol/L BMS-777607, 10 umol/L wortmannin, or with BMS-777607 in combination with individual inhibitors. Polyploidy was examined under BK71 Olympus microscope and photographed 72 hours after treatment. |

GSK461364GSK461364 (GSK461364A) inhibits purified Plk1 with Ki of 2.2 nM in a cell-free assay. It is more than 1000-fold selective against Plk2/3. Phase 1. |
![]() ![]() Cells with decreased GRK5 expression are more sensitive to PLK1 inhibition.A , shown is cell death in control or GRK5-shRNA stably transfected cells after 72 h of treatment with 0-120 nM BI 2536 as determined by trypan blue exclusion (n = 6).B , shown is cell death in control or GRK5-shRNA stably transfected cells after 72 h treatment with 0 –120 nM GSK461364, as determined by trypan blue exclusion ( n = 4). |

Ro3280RO3280 (Ro5203280) is a potent, highly selective inhibitor of Polo-like kinase 1 (PLK1) with IC50 of 3 nM. |
![]() ![]() RO3280 promotes the formation of multinucleated cells in bladder cancer cell lines. (A) Representative images of cells stained with DAPI (blue) and alpha‐tubulin (red) were examined under a fluorescence microscope (magnification 400×). Enlarged cells containing multiple evenly stained nuclei (multinucleated cells) are characteristic of mitotic catastrophe (white arrow). (B) Quantification of the percentage of multinucleated cells based on fluorescence microscopy analysis (the data are presented as the mean ± S.E.M., *P < 0.05).
