MLN0905 (MLN-0905; MLN 0905) is a novel, potent and selective small-molecule inhibitor of polo-like kinase-1 (PLK1) with potential antineoplastic activity. Its IC50 is 2 nM, which inhibits PLK1. A wide variety of human tumor cells, including DLBCL cell lines, are inhibited in their ability to proliferate by MLN0905. In several DLBCL models, pharmacodynamic pHisH3 modulation and strong antitumor activity are the results of PLK1 inhibition. These findings strongly support testing PLK1 inhibitors as DLBCL anticancer drugs in clinical settings.

Enzyme Assay |
Thirty microliters of human PLK1 enzymatic reaction were used, along with 50 mM Tris-HCl (pH 8.0), 10 mM MgCl2, 0.02% BSA, 10% glycerol, 1 mM DTT, 100 mM NaCl, 3.3% DMSO, eight microliters of ATP, 0.2 microliters of [γ-33P]-ATP, four microliters of peptide substrate (Biotin-AHX-LDETGHLDSSGLQEVHLA-CONH2), and ten nanoliters of recombinant human PLK1[2–369]T210D. PLK inhibitors or not, the enzymatic reaction mixture is incubated for 2.5 hours at 30 degrees Celsius before being stopped with 20 microliters of 150 mM EDTA. After that, 25μL of the stopped enzyme reaction mixture is put on an Image FlashPlate coated with streptavidin that has 384 wells, and it is left to sit at room temperature for three hours. After three Tween-20 washes (0.02%), the Image Flash Plate wells are read using a Perkin-Elmer Viewlux.

Cell Assay |
MLN0905 functions similarly to RNAi knockdown and is a selective PLK1 inhibitor. MLN0905 treatment dramatically increased pHisH3 expression in HT-29 cells, indicating that PLK1 expression was inhibited and cell arrest in the G2/M phase resulted.

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.14 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (5.14 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
