  2. Polo-like Kinase (PLK) Autophagy
  3. SBE13


目录号: HY-15158A

SBE13 是一种有效的,选择性的 Plk1 抑制剂,IC50 值为 200 pM,对 Plk2 (IC50>66 μM) 或 Plk3 (IC50=875 nM) 的作用较弱。

在相同的摩尔浓度下,化合物盐形式与游离形式有相同的生物活性,但盐形式 SBE13 Hydrochloride 通常具有更好的水溶性和稳定性。

SBE13 is a potent and selective Plk1 inhibitor, with an IC50 of 200 pM; SBE13 poorly inhibits Plk2 (IC50>66 μM) or Plk3 (IC50=875 nM).

IC50 & Target[1]


200 pM (IC50)


875 nM (IC50)

(In Vitro)

SBE13 significantly reduce cell proliferation and induce apoptosis in HeLa cells, with an EC50 of 18 μM[1]. SBE13 (1-100 μM) shows no effect on Caspase 3/7 activity in NIH-3T3 cells. SBE13 (66 and 100 μM) does not change morphology after treatment of primary cells. SBE13 (10 and 100 μM) reduces pRb staining in primary cells, and this indicates a G0/G1 arrest[2]. SBE13 (66 and 100 μM) increases levels of cyclin B1, phospho histone H3, Wee1, Emi1 and securin, and results in cleavage of Cdc27 in HeLa cells. SBE13 (10 and 100 μM) also induces apoptosis of HeLa cells[3].

Kinase Assay

To assay Plk1 kinase activity, cells are lysed after 13 h release in the presence of SBE13 after double thymidine block and kinase is immunoprecipitated from lysates using antibodies. In brief, for each immunoprecipitation 800 μg of total protein are incubated with Plk1 antibody cocktail (1.5 μg) for 2 h at 4°C on a rotator. Immunoprecipitated protein is collected using Protein A/G Agarose beads. Plk1 immunoprecipitates are incubated with casein (1 μg) and with [γ-32P]ATP (1 μCi) for 30 min at 37°C in kinase buffer. Products from the kinase assays are fractionated on 10 % bis-tris-polyacrylamide gels, and phosphorylated substrate is visualized by autoradiography after an exposure of 12-36 h. Equal amounts of immunoprecipitates are subjected to Western blot analysis to confirm equal loading of Plk1 protein in kinase reactions[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
