Chemical Name: 2,3,4,6,7,8-Hexahydro-4-(3-hydroxyphenyl)-7,7-dimethyl-2-thioxo-5(1H)-quinazolinone

Biological Activity

Inhibitor of mitotic motor kinesin Eg5 (IC50 = 200 nM). Arrests mitosis, triggers apoptosis and up-regulates Hsp-70 expression in multiple human myeloma cell lines. Also inhibits the growth of several types of cancer cell lines (EC50 values are 330, 603, 743 and 881 nM in HCT116, Htert-HME1, BxPC3, K562 and NCI-H1299 cancer cells, respectively). Suppresses the migration and invasion of PANC1 cells in vitro. Cytoprotective.
