TAPI-2 is a broad-spectrum inhibitor of MMP (IC50: 20 μM), tumour necrosis factorα-converting enzyme (TACE) and a disintegrin and metalloproteinase (ADAM).
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].
AZD1236 is a potent and reversible inhibitor of human MMP-9 and MMP-12 (IC50 = 4.5 and 6.1nM, respectively), with >10-fold selectivity to MMP-2 and MMP-13 and >350-fold selectivity to other members of the enzyme family. AZD1236 activity is approximately 20 to 50-fold lower at the rat, mouse, and guinea pig orthologues. In acute models of lung injury, AZD1236 inhibited the haemorrhage and inflammation induced by instillation of human MMP-12 into rat lungs by ~80% at 0.81mg kg, and also abolished macrophage infiltration into BAL fluid induced by tobacco smoke inhalation in the mouse.
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.
Cyclopamine-KAAD is a potent inhibitor of hedgehog signaling with an IC50 value of 20 nM in a Shh-LIGHT2 assay. It blocks binding of BODIPY-cyclopamine to cells expressing Smoothened (Smo) in a dose-dependent manner. Cyclopamine-KAAD is cell-permeable and binds to SmoA1 to promote its exit from the endoplasmic reticulum. It inhibits the invasion and migration (45.9 and 43.3% inhibition, respectively) of Bel-7402 hepatocarcinoma cells and decreases the expression of nuclear glioma-associated oncogene 1 (Gli1) and cytosolic MMP-9, pERK1, and pERK2 proteins in a dose-dependent manner. Cyclopamine-KAAD also increases TRAIL-mediated cell death in NCH82 and NCH89 human glioblastoma cultures and upregulates expression of the death receptors DR4 and DR5 in LN229 and U251 glioma cells.
FSL-1 TFA, a bacterial-derived toll-like receptor 2 6 (TLR2 6) agonist, enhances resistance to experimental HSV-2 infection[1]. FSL-1 TFA induces MMP-9 production through TLR2 and NF-κB AP-1 signaling pathways in monocytic THP-1 cells[2]. FSL-1 significantly reduces HSV-2 replication in human vaginal epithelial cells (EC)[1].FSL-1 induces significant resistance to experimental genital HSV-2 infection through elaboration of a specific cytokine response profile[1].FSL-1 (50 ng mL, 24 hours) induces MMP-9 expression at both mRNA and protein levels in human monocytic THP-1 cells[2].FSL-1 activates the MAP kinase NF-κB signaling pathway[2]. Cell Viability Assay[1] Cell Line: V11I, V12I or V19I immortalized human vaginal EC FSL-1 application significantly protectes against genital HSV-2 challenge in mice[1]. Animal Model: Female Swiss-Webster mice (weighing 20-25 g)[1] [1]. William A Rose 2nd, et al.
