Chemical Name: 1,2,3,4-Tetrahydro-4-(3-hydroxyphenyl)-6-methyl-2-thioxo-5-pyrimidinecarboxylic acid, ethyl ester

Biological Activity

Potent, cell-permeable, small molecule mitosis inhibitor that does not interact with tubulin. Arrests cells in mitosis and specifically inhibits the motility of the mitotic kinesin Eg5, a motor protein required for mitotic spindle formation and maintenance (IC50 = 14 μM).
