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.

Mechanism of Action

Targets/IC50/Ki
PLK1
2 nM
In vitro
MLN0905 is a potent inhibitor of PLK1 with IC50 of 2 nM. It inhibits cell mitosis with EC50 of 9 nM. This compound inhibits Cdc25C-T96 phosphorylation, a direct readout of PLK1 inhibition with EC50 of 29 nM. It inhibits HT-29 viability with LD50 of 22 nM. This chemical possesses reasonable selectivity against a panel of 359 kinases. It inhibits a panel of lymphoma cells viability with IC50 of 3 – 24 nM.
Kinase Assay
PLK1 Flash Plate Assay
The human PLK1 enzymatic reaction totaling 30μL contained 50 mM Tris-HCl (pH 8.0), 10 mM MgCl2, 0.02% BSA, 10% glycerol, 1 mM DTT, 100 mM NaCl, 3.3% DMSO, 8 μM ATP, 0.2μCi [γ- 33 P]-ATP, 4μM peptide substrate (Biotin-AHX-LDETGHLDSSGLQEVHLA-CONH2), and 10 nM recombinant human PLK1[2–369]T210D. The enzymatic reaction mixture, with or without PLK inhibitors, is incubated for 2.5 h at 30℃before termination with 20μL of 150 mM EDTA. Then 25μL of the stopped enzyme reaction mixture is transferred to a 384-well streptavidin coated Image FlashPlate and incubated at room temperature for 3 h. The Image Flash Plate wells are washed three times with 0.02% Tween-20 and then read on the Perkin-Elmer Viewlux.
In vivo
Nude mice bearing HT-29 xenografts administered with MLN0905 (6.25 mg/Kg - 50 mg/Kg, p.o.) shows dose-dependent pharmacodynamic responses (48 hours after treatment). OCI LY-19-Luc tumor bearing mice administered with this compound (3.12 mg/Kg – 6.25 mg/Kg, p.o.) shows significant pharmacodynamic responses amd peaks at 8 hours after treatment. This compound shows antitumor efficacy in treatment with OCI LY-19-Luc xenografts bearing scid mice for 21 days. The T/C of 6.25 mg/Kg daily group is 0.15.
