This inhibitor was designed to potently inhibit MMP activities while minimally affecting those of other metalloproteases (e.g., sheddases) involved in the release of cell-associated molecules such as tumor necrosis factor-α, tumor necrosis factor-α receptor, interleukin-6 receptor, or l-selectin. In vitro, BMS-275291 is a potent inhibitor (nm) of the activities of MMP-1, MMP-2, MMP-7, MMP-9, and MMP-14. BMS-275291 inhibits tumor growth in a B16BL6 model of experimental metastasis, and in this model, BMS-275291 treatment results in a dose-dependent reduction in the number of lung metastases compared with vehicle controls. BMS-275291 also inhibits angiogenesis in a murine angiogenesis model, where once daily treatment with BMS-275291 results in a dose-dependent inhibition of endothelial cell migration into s.c. implanted Matrigel plugs. Pharmacokinetic studies demonstrated that the plasma concentrations of parent BMS-275291 in mice exceeds the in vitro IC50 values for MMP-1, MMP-2, MMP-7, MMP-9, and MMP-14 for at least 4 h after the administration of a therapeutic dose of BMS-275291. Taken together, these data demonstrate that BMS-275291 inhibits MMP activities that contribute to tumor metastasis and angiogenesis. ©2001 American Association for Cancer Research.
