Matrix metalloproteinase-3 (MMP-3), also known as stromelysin-1, is a critical enzyme involved in tissue remodeling and repair through its role in degrading extracellular matrix proteins, facilitating cell migration. This enzyme has been implicated in various physiological processes including vascular remodeling associated with aneurysm formation, wound healing, the progression of atherosclerosis, and tumor initiation. MMP-3 inhibitor VIII, a cell-permeable sulfonamide-based hydroxamic acid, effectively inhibits MMP-3 by binding to its active site (Ki = 23 nM), thus blocking its enzymatic activity. Additionally, this inhibitor has been demonstrated to suppress the activity of mouse macrophage metalloelastase MME/MMP-12, with an IC50 value of 13 nM, highlighting its potential utility in research on tissue remodeling and disease processes involving MMPs.
Prinomastat hydrochloride is a orally active inhibitor of metalloproteinase (MMP)(MMP-1, MMP-3 and MMP-9 with IC50s of 79, 6.3 and 5.0 nM , respectively),with Antitumor avtivity.
UK-370106 is a potent and highly selective inhibitor of MMP-3 with IC50 of 23 nM and MMP-12 with IC50 of 42 nM, and potently inhibits cleavage of [3H]-fibronectin by MMP-3 (IC50: 320 nM).
XL-784 free base is a selective inhibitor of matrix metalloproteinases (MMP), (IC50s of ~1900, 0.81, 120, 10.8, 18, 0.56 nM for MMP-1,MMP-2,MMP-3,MMP-8,MMP-9,MMP-13,respectively).
Actinonin ((-)-Actinonin) is a naturally occurring antibacterial agent produced by Actinomyces and a potent reversible peptide deformylase (PDF) inhibitor with a Ki of 0.28 nM, it also is an apoptosis inducer. Actinonin inhibits aminopeptidase M, aminopeptidase N and leucine aminopeptidase, it also inhibits MMP-1, MMP-3, MMP-8, MMP-9, and hmeprin α with Ki values of 300 nM, 1,700 nM, 190 nM, 330 nM, and 20 nM, respectively. Actinonin has antiproliferative and antitumor activities[1][2][3][4][5].
Tanomastat is an orally bioavailable and non-peptidic biphenyl matrix metalloproteinases inhibitor. For MMP-2, MMP-3, MMP-9, MMP-13 the Ki values are 11, 143, 301, and 1470 nM respectively.
