In vivo Batch:
Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	1.650mg/ml (2.60mM)	Taking the 1 mL working solution as an example, add 50 μL of 33 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

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	PLK4 (Cell-free assay) 0.16 nM(Ki)
In vitro	Centrinone (LCR-263) prevents centriole assembly by inhibiting Plk4. Centrinone treatment causes centrosome depletion in human and other vertebrate cells.<sup><a class="sref" href="#s_ref">[1]</a></sup>
Kinase Assay
Kinase Assay	Purified 6xHis-tagged human Plk4 kinase domain is in 20 mM Tris pH 7.5, 100 mM NaCl, 10% glycerol, 1 mM DTT. 2X reaction buffer consists of 50 mM HEPES pH 8.5, 20 mM MgCl2, 1 mM DTT, 0.2 mg/mL BSA, 16 μM ATP, and 200 μM A-A11 substrate. The Plk4 concentration in the final reaction is 2.5-10 nM with a final pH of 8.0. Centrinone array in dose response are added from DMSO stocks. Reactions are allowed to proceed for 4-16 hours at 25°C. Detection is performed using ADP-Glo reagent. Luminescence is measured on a plate reader.
