Description BI2536 is an effective Plk1 inhibitor (IC50: 0.83 nM). It has 4- and 11-fold greater selectivity than Plk2 and Plk3.
Targets&IC50 Met : ic50 4.754μM,   PI3Kα : ic50 2.407μM,   PLK1 : ic50 0.83nM,   PLK2 : ic50 3.5nM,   PLK3 : ic50 9.0nM,  
In vitro BI 2536 inhibits Plk1 enzyme activity at low nanomolar concentrations. The compound potently causes a mitotic arrest and induces apoptosis in human cancer cell lines of diverse tissue origin and oncogenome signature [1]. On treatment with nanomolar doses of BI 2536, ATC cells progressed normally through S phase but died thereafter, directly from mitotic arrest. Nontransformed thyroid cells were 3.2- to 18.4-fold less susceptible to BI 2536-induced cell cycle effects compared with ATC cells [2].
In vivo BI 2536 inhibits growth of human tumor xenografts in nude mice and induces regression of large tumors with well-tolerated intravenous dose regimens. In treated tumors, cells arrest in prometaphase, accumulate phosphohistone H3, and contain aberrant mitotic spindles [1].
Kinase Assay Plk1 in vitro kinase assay: Recombinant human Plk1 (residues 1-603) is expressed as N-terminal, GST-tagged fusion protein with a baculoviral expression system and purified by affinity chromatography with Glutathione-agarose. Enzyme activity assays for Plk1 are performed in the presence of serially diluted BI 2536 with 20 ng of recombinant kinase and 10 μg casein from bovine milk as the substrate. Kinase reactions are performed in a final volume of 60 μL for 45 minutes at 30 °C (15 mM MgCl2, 25 mM MOPS [pH 7.0], 1 mM DTT, 1% DMSO, 7.5 mM ATP, 0.3 μCi γ-33P-ATP). Reactions are terminated by the addition of 125 μL of ice-cold 5% TCA. After transfer of the precipitates to Multi-Screen mixed ester cellulose filter plates, plates are washed with 1% TCA and quantified radiometrically. Dose-response curve is used for calculating IC50 value.
Cell Research
Cells are exposed to various concentrations of BI 2536 for 24, and 72 hours. Cell growth is assessed by the measurement of Alamar Blue dye conversion in a fluorescence spectrophotometer. For determining the DNA content of the cultures, cell suspensions are fixed in 80% ethanol, treated for 5 minutes with 0.25% Triton X-100 in PBS, and incubated with 0.1% RNase and 10 μg/mL propidium iodide (PI) in PBS for 20 minutes at RT. Cell-cycle profiles are determined by flow cytometric analysis.(Only for Reference)
Cell lines: HeLa, A43, SKOV-3, HT-29, K562, A549, Saos-2, MCF7, HCT116, COLO 205, Hep G2, Raji and PC-3 cells, etc.

Molarity Calculator allows you to calculate the

  • mass of a compound required to prepare a solution of known volume and concentration
  • volume of solution required to dissolve a compound of known mass to a desired concentration
  • concentration of a solution resulting from a known mass of compound in a specific volume
See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
