Competitive, mechanism-based inhibitor of matrix metalloproteinases 2 and 9 (MMP-2 and MMP-9). It possesses Ki values in the nanomolar range against the gelatinases (14nM for MMP-2; 600nM for MMP-9), but in the micromolar range against other metalloproteinases (206µM for MMP-1, 15µM for MMP-3, 96µM for MMP-7, and 4µM for ADAM17/TACE). This inhibitor has also been used in vitro, in vivo, and in tissue culture. In vivo, it is metabolized to an even more potent gelatinase inhibitor. Purity: ≥98% (TLC). Solubility: Soluble in DMSO (at least 30mM) or 100% ethanol. Long Term Storage: -20°C.
