In Vitro

MK-5108 inhibits Aurora-A activity with an IC₅₀ value of 0.064 nM in an ATP-competitive manner. It shows robust selectivity against the other family kinases Aurora-B (220-fold) and Aurora-C (190-fold). MK-5108 also exhibits high selectivity for Aurora-A over other protein kinases. MK-5108 inhibits the growth of 14 cell lines with IC₅₀ values between 0.16 and 6.4 μM^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

MK-5108 treatments at 15 and 30 mg/kg results in significant tumor growth inhibition in the HCT116 tumor model. MK-5108 is well tolerated at both doses, with minimal reduction in body weight. MK-5108 also exhibits significant antitumor activity in nude rats bearing SW48 tumors. MK-5108 at 15 and 45 mg/kg causes dose-dependent tumor growth inhibition with a %T/C of 35% and 7% at day 10, and 58% and 32% at day 27, respectively. MK-5108 is well tolerated in nude rats, with no body weight reduction and moderate effect on blood cells^[1].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 1.25 mg/mL (2.71 mM); Clear solution

This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 1.25 mg/mL (2.71 mM); Clear solution

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 1.25 mg/mL (2.71 mM); Clear solution

This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL Corn oil, and mix evenly.

For the following dissolution methods, please prepare the working solution directly:

It is recommended to prepare fresh solutions and use them promptly within a short period of time.

The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol

Kinase Assay^[1]

The Aurora-A assay reaction is conducted in the presence of 20 μM ATP, 25 μM Tetra-Kemptide, 1.0 μCi per well [γ-³³P]-ATP, 0.1 ng per well Aurora-A in 50 mmol/L Tris-HCl (pH 7.4), 15 mmol/L Mg(OAc)₂, and 0.2 mmol/L EDTA at 30°C for 40 min. To investigate the inhibition mode of MK-5108 for Aurora-A, the IC₅₀ values of MK-5108 are determined in the presence of different concentrations of ATP. Then, the IC₅₀ value is plotted as a function of ATP concentration to analyze the effect of ATP concentration on the IC₅₀ value of MK-5108^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Assay^[1]

Cells are seeded in 96-well plates then incubated overnight. A medium containing MK-5108, docetaxel, or DMSO control is added and is incubated for 72 h. The cell population densities are then measured by the WST-8 colorimetric assay using a SpectraMax Plus384 plate reader. Concentration response curves are generated to give the decrease in cell population density in MK-5108– and docetaxel-treated samples relative to DMSO-treated control. Growth inhibition IC₅₀ values are determined from those curves^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration^[1]

Rats: After 8 d, MK-5108 is suspended in 0.5% methyl cellulose/0.24% SDS and orally administered twice daily for 14 d. SW48 cells are suspended in 50% Matrigel/50% PBS and s.c. transplanted into the side flank of nude rats. After 7 d, MK-5108 is suspended in 0.5% methyl cellulose/0.24% SDS and orally administered twice daily for 2 d/wk for 3 wk. In a HeLa-luc and ES-2 dual flank xenograft model, HeLa-luc or ES-2 cells are suspended in 50% Matrigel and 50% PBS, and s.c. transplanted into the right or left side flank of nude rats. After 8 d, vehicle (5% ethanol-saline) or 7.5 mg/kg docetaxel is injected i.v. MK-5108 is orally administered twice daily for 2 d 24 h after the docetaxel injection. The volume of each tumor is determined from the tumor diameter^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
