This compound is a cell-permeable, selective, and reversible thiopyrimidone MMP-9 allosteric inhibitor that binds specifically to the non-catalytic site of MMP-9 at the PEX domain with a =2.1uM and thereby disrupts MMP-9 homodimerization and its cross-talk with CD44 and the EGFR-MAPK signaling pathway. It does not bind to the PEX domain of MMP-2 or MT1-MMP and it is shown to decrease MMP-9 mediated cell migration in COS-1 cells at 100uM. Also, it inhibits cell migration and invasion of HT-1080 and MDA-MB-435 human cancer cells in a dose-dependent manner from 0.1 to 100M, without altering MMP-9 expression or proteolytic activity in HT-1080 cells. In addition, it attenuates both primary tumor growth and metastasis in vivo in a mouse model without obvious toxicity (20mg/kg, 6 days/week, i.v. and i.t.).
