Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/20053775

MK-5108 is a small molecule inhibitor of AuroraA kinase with high selectivity versus Aurora-B and C. It was tested in phase I study against advanced or refractory solid tumors both as a monotherapy or in combination with docetaxel, but this study was terminated early due to toxicities at MK-5108 doses below the anticipated PK exposure target.

Sample Use Guides

In Vivo Use Guide

In a randomized phase I study of against advanced or refractory solid tumors MK-5108 was administered p.o. BID Q12h on days 1-2 in 14-21 day cycles either alone (200 to 1800 mg) or in combination (100 to 225 mg) with IV docetaxel 60 mg/m(2).

Route of Administration: Oral

In Vitro Use Guide

Recombinant His-tagged human Aurora-A protein was expressed in Escherichia coli and was purified with HisTrap HP column (GE Healthcare). The Aurora-A assay reaction was conducted in the presence of 20 μmol/L ATP, 25 μmol/L Tetra-Kemptide [RRR(GLRRASLG)4R-NH2], 1.0 μCi per well [gamma-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 were determined in the presence of different concentrations of ATP. Then, the IC50 value was plotted as a function of ATP concentration to analyze the effect of ATP concentration on the IC50 value of MK-5108.
