Talabostat (PT100, Val-boroPro) is a potent, nonselective and orally available dipeptidyl peptidase IV (DPP-IV) inhibitor with a Ki of 0.18 nM. Talabostat is a nonselective DPP-IV inhibitor, inhibiting DPP8 9, FAP, DPP2 and some other DASH family enzymes essentially as potently as it inhibits DPP-IV[1]. Talabostat stimulates the immune system by triggering a proinflammatory form of cell death in monocytes and macrophages known as pyroptosis. The inhibition of two serine proteases, DPP8 and DPP9, activates the proprotein form of caspase-1 independent of the inflammasome adaptor ASC[2]. Talabostat competitively inhibits the dipeptidyl peptidase (DPP) activity of FAP and CD26 DPP-IV, and there is a high-affinity interaction with the catalytic site due to the formation of a complex between Ser630 624 and the boron of talabostat[3]. Talabostat can stimulate immune responses against tumors involving both the innate and adaptive branches of the immune system. In WEHI 164 fibrosarcoma and EL4 and A20 2J lymphoma models, PT-100 causes regression and rejection of tumors. The antitumor effect appears to involve tumor-specific CTL and protective immunological memory. Talabostat treatment of WEHI 164-inoculated mice increases mRNA expression of cytokines and chemokines known to promote T-cell priming and chemoattraction of T cells and innate effector cells[3]. Talabostat treated mice show significant less fibrosis and FAP expression is reduced. Upon PT100 treatment, significant differences in the MMP-12, MIP-1α, and MCP-3 mRNA expression levels in the lungs are also observed. Treatment with PT100 in this murine model of pulmonary fibrosis has an anti-fibro-proliferative effect and increases macrophage activation[4]. [1]. Connolly BA, et al.

PD-166793 is an orally active, potent and selective MMP inhibitor with inhibitory effects on MMP-2, MMP-3 and MMP-13.PD-166793 ameliorates myocardial ischemia and reperfusion injury in a rat model of heart failure.PD-166793 is an orally active, potent and selective MMP inhibitor with inhibitory effects on MMP-2, MMP-3, and MMP-13.

NF157 significantly decreases the expression of metalloproteinase (MMP)-3, MMP-13, which can be used in the treatment of osteoarthritis (OA). NF157 is a highly selective nanomolar P2Y11 antagonist (pKi: 7.35). The IC50s are 463 nM, 1811 µM, 170 µM for P2Y

Broad spectrum MMP inhibitor (IC₅₀ values are 0.7, 0.9, 13, 16 and 1170 nM for MMP-2, MMP-13, MMP-9, MMP-3 and MMP-1 respectively). Attenuates early left ventricular dilation after experimental myocardial infarction in mice.

GM 1489 is a broad-spectrum inhibitor of matrix metalloproteinases (MMPs) with Ki values of 0.002, 0.1, 0.5, 0.2, and 20 μM for MMP-1, MMP-8, MMP-2, MMP-9, and MMP-3, respectively. It reduces 5-aza-2'-deoxycytidine-induced increases in MMP-1, MMP-2, MMP-3, MMP-7, MMP-9, and MMP-14 expression as well as cell invasion in AsPC-1, BxPC-3, Hs766T, MiaPaCa2, and PANC-1 cancer cells. Topical administration of GM 1489 (100 μg) inhibits increases in ear thickness and epidermal hyperplasia induced by phorbol 12-myristate 13-acetate and phorbol dibutyrate (PdiBu) in mice.

MMP13-IN-2 is a highly potent, selective, and orally active inhibitor of MMP-13. It demonstrates exceptional potency against MMP-13, with an IC50 value of 0.036 nM, and exhibits selectivities greater than 1,500-fold over MMP-1, 3, 7, 8, 9, 14, and TACE. Moreover, MMP13-IN-2 possesses the capability to effectively inhibit collagen release from cartilage in vitro. Consequently, MMP13-IN-2 holds great potential for advancing research on collagenase-related diseases.

(Rac)-Tanomastat ((Rac)-BAY 12-9566) is a racemate of Tanomastat. Tanomastat (BAY 12-9566) is an orally active zinc carboxy-containing inhibitor of non-peptide biphenyl matrix metalloproteinases (MMPs) and inhibits MMP-2 (Ki: 11 nM), MMP-3 (Ki: 143 nM), MMP-9 (Ki: 301 nM), and MMP-13 (Ki: 1470 nM). In several experimental tumor models, Tanomastat exhibits anti-invasive and anti-metastatic effects.

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.
