Biological Activity

Description SBE 13 HCl is a potent and selective PLK1 inhibitor with IC50 of 200 pM, >4000-fold selectivity over Aurora A kinase, Plk2 and Plk3.
Targets
PLK1 [1]
200 pM
In vitro
In vitro SBE 13 decreases cell proliferation in various cancer cell lines, and causes a G2/M arrest followed by apoptosis. [1] In primary cells, SBE 13 does not impair cell cycle and thus proliferation of primary cells. [2] SBE13 in combination with Enzastaurin displays a synergistic reduction of cell proliferation and enhanced apoptosis induction in HCT116(p53-/-) cells. [3]
Kinase Assay Kinase assays
To assay Plk1 and Aurora A kinase activity, cells are lysed after 13 hrs release in the presence of SBE13 after double thymidine block, and kinases are immunoprecipitated from lysates using antibodies as described. In brief, for each immunoprecipitation 800 µg of total protein were incubated with 1.5 µg Plk1 antibody cocktail, 3 µg Plk2 antibody, 3 µg Plk3 antibody, or 5 µg Aurora A antibody, respectively, for 2 hrs at 4°C on a rotator. Immunoprecipitated protein is collected using Protein G Agarose beads. The Plk1, Plk2 and Plk3 immunoprecipitates are incubated with 1 µg casein and with 1 µCi of [γ32-P]ATP for 30 min at 37°C in kinase buffer. The Aurora A immunoprecipitates are incubated with 0.5 µl Histone and with 1 µCi of [γ32-P]ATP for 60 min at room temperature in kinase buffer. Products from the kinase assays are fractionated on 10% Bis-Tris-polyacrylamide gels, and the phosphorylated substrate is visualized by autoradiography after an exposure of 12 to 36 hrs. An equal amount of immunoprecipitates is subjected to western blot analysis to confirm equal loading of Plk1, Plk2, Plk3 or Aurora A protein in kinase reactions. Immunoprecipitated Plk1 after 13 hrs release in the presence of SBE13 is assayed after de-phosphorylation using λ protein phosphatase and compared to kinase activity of endogenous immunoprecipitated Plk1. Activity of Plk1 kinase with and wiiiuithout de-phosphorylation is compared and the ratio between de-phosphorylated and “normal” endogenous immunoprecipitated Plk1 kinase activity is calculated.

Concentrations 100 μM
Incubation Time 72 hours
Method Cells are treated with SBE13 one day after subculturing. Control cells are incubated with normal culture medium. Concentrations of SBE13 ranged from 1 nM–100 µM. The growth rate of 1 x 105 cells per 6-well is determined by counting cells at 24, 48 and 72 hours after treatment. Cell culture studies are performed in triplicate for each time point.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
