Polo-like Kinase (PLK) Inhibitor

Polo-like Kinase (PLK) Inhibitors (25):

Cat. No. Product Name Effect Purity
  • HY-156336
    PLK1-IN-7
    		Inhibitor
    PLK1-IN-7 (compound 30e) is a potent PLK1 inhibitor, with an IC50 of 0.66 nM. PLK1-IN-7 exhibits antiproliferative and antitumor activities.
  • HY-12135
    Poloxipan
    		Inhibitor
    Poloxipan is a pan-specific polo-like kinase (PLK) inhibitor that can inhibit a non-catalytic region at the C-terminus called the Polo-box domain (PBD) found in kinases. The IC50 values for Poloxipan against the PBDs of PLK-1/2/3 are 3.2 μM, 1.7 μM, and 3.0 μM, respectively. Poloxipan also inhibits other phospho-tyrosine binding domains, such as the forkhead-associated (FHA) domain of CHK-2, the WW domain of peptidyl-prolyl cis/trans isomerase (PIN1), and the phospho-tyrosine binding domains of STAT1/3/5 and lymphocyte-specific protein tyrosine kinase's SH2 domain. Poloxipan can be used in cancer research.
  • HY-129265
    Poloxin-2
    		Inhibitor
    Poloxin-2 is a small molecule Plk1 PBD inhibitor that can effectively induce cell mitotic arrest with an EC50 of approximately 15 μM in HeLa cells. Poloxin-2HT was developed by conjugating a hydrophobic tag (HT) to Poloxin-2, a new application of inhibitors targeting protein-protein interactions. Poloxin-2HT significantly enhanced the effects on cell viability and apoptosis by selectively degrading Plk1 protein, and its effect was stronger than that of untagged Poloxin-2. These data validate hydrophobic tags as a new strategy for targeting and disrupting disease-associated proteins.
  • HY-W276819
    PLK1-IN-9
    		Inhibitor
    PLK1-IN-9 (Compound M2) is an inhibitor for polo-like kinase 1 (PLK1), that inhibits PLK proteins modified with peptides 1010pT, cdc25c and PBIP, with IC50s of 1.6, 0.8 and 1.4 μM, respectively. PLK1-IN-9 inhibits proliferations of cancer cells HeLa, HL60, SNU387/499, HepG2, exhibits cytotoxicity and induces apoptosis. PLK1-IN-9 inhibits tumor growth in HepG2 xenograft mouse model.
  • HY-160624
    CD 10899
    		Inhibitor
    CD 10899 is a hydroxylated metabolite of Volasertib (HY-12137). CD 10899 is pharmacologically active against Polo-like kinase 1 (PLK1) (IC50: 6 nM). Volasertib is an orally active, highly potent and ATP-competitive PLK1 inhibitor. CD 10899 can be used for research of cancer.
