SEMBL is a potent NF-κB inhibitor. SEMBL can inhibit NF-κB-DNA binding, and also inhibits NF-κB-dependent inflammatory cytokine secretions. SEMBL inhibits cancer cell migration and invasion via decreasing MMP expression. SEMBL can be used for researching anticancer[1].
SEMBL inhibits MMP-2 expression and cellular metastatic activity in ovarian carcinoma cells[1].
SEMBL inhibits the cell-free DNA binding of NF-κB in the ES-2 nuclear extract and inhibits the constitutively activated NF-κB activity in ovarian carcinoma cells[1].
SEMBL inhibits cellular migration, invasion and MMP-2 expression in ovarian carcinoma cells at non-toxic concentrations[1].

Inhibition of matrix metalloproteinase expression and cellular invasion by NF-κB inhibitors of microbial origin
Biochim Biophys Acta Proteins Proteom 2020 Jun;1868(6):140412.PMID:32179183DOI:10.1016/j.bbapap.2020.140412.
Matrix metalloproteinases (MMPs) are zinc-dependent extracellular matrix remodeling endopeptidases. MMPs cleave various matrix proteins such as collagen, elastin, gelatin and casein. MMPs are often implicated in pathological processes, such as cancer progression including metastasis. Meanwhile, microorganisms produce various secondary metabolites having unique structures. We designed and synthesized dehydroxymethylepoxyquinomicin (DHMEQ) based on the structure of epoxyquinomicin C derived from Amycolatopsis as an inhibitor of NF-κB. This compound inhibited cancer cell migration and invasion. Since DHMEQ is comparatively unstable in the body, we designed and synthesized a stable DHMEQ analog, SEMBL. SEMBL also inhibited cancer cell migration and invasion. We also looked for inhibitors of cancer cell migration and invasion from microbial culture filtrates. As a result, we isolated a known compound, ketomycin, from Actinomycetes. DHMEQ, SEMBL, and ketomycin are all NF-κB inhibitors, and inhibited the expression of MMPs in the inhibition of cellular migration and invasion. These are all compounds with comparatively low toxicity, and may be useful for the development of anti-metastasis agents.
