    Description: 6,7-Dihydroxycoumarin(Esculetin) has various biological and pharmaceutical properties including anti-edema, anti-inflammatory, anti-tumour, hepatoprotective, anti-osteoarthritis and anti-rheumatoid arthritis effects. It inhibits lipoxygenases (LOs), p42/44 MAPK activation, PI3-kinase activation, as well as NF-kappaB and AP-1 activation, it exhibits competitive inhibition against the oxidation of 3-(3,4-dihydroxyphenyl)- alanine by mushroom, the IC50 value of is 43 microM.
    Targets: HO-1 | NO | AP-1 | MCP-1 | TNF-α | PPAR | NF-kB | PI3K

    Esculetin (6,7-dihydroxycoumarin): a potential cancer chemopreventive agent through suppression of Sp1 in oral squamous cancer cells.[Pubmed: 25310400]
    Esculetin (6,7-dihydroxycoumarin), a coumarin compound, is known to inhibit proliferation and induce apoptosis in several types of human cancer cells and is regarded as a promising chemotherapeutic agent.
    METHODS AND RESULTS:
    The purpose of the present study was to investigate the anti-proliferative effects of esculetin on two oral squamous cell carcinoma (OSCC) cell lines, HN22 and HSC4, through regulation of specificity protein 1 (Sp1). We examined the apoptotic effects of esculetin were measured by MTS assay, DAPI staining, Annexin V, PI staining, RT-PCR, western blot analysis and immunocytochemistry in HN22 and HSC4 cells. Taken together, the results of the present study indicate that esculetin had anti-proliferative effect on the growth of OSCC cells (HN22 and HSC4) in a dose- and time-dependent manner. The treatment of HN22 and HSC4 cells with esculetin led to a significant reduction in growth and induced apoptosis, followed by the regulation of Sp1 and Sp1 regulatory protein.
    CONCLUSIONS:
    This indicates that esculetin inhibited cell growth and induced apoptosis by suppressing Sp1 in HN22 and HSC4 cells, suggesting it to be a potent anticancer drug candidate for oral cancer.

    Esculetin inhibits the inflammatory response by inducing heme oxygenase-1 in cocultured macrophages and adipocytes.[Pubmed: 25088305]

    METHODS AND RESULTS:
    In this study, we investigated the anti-inflammatory effects of esculetin (6,7-dihydroxycoumarin,ECT) through up-regulation of heme oxygenase-1 (HO-1) in cocultured macrophages and adipocytes. RAW264.7 macrophages and differentiated 3T3-L1 adipocytes were cocultured in serum-free Dulbecco's modified Eagle's medium with or without ECT for 24 h. Nitric oxide (NO), tumor necrosis factor-α (TNF-α), and monocyte chemoattractant protein-1 (MCP-1) production was measured in the coculture supernatant. ECT decreased the secretion of NO, TNF-α, and MCP-1. The expression of adipogenic proteins, including peroxisome proliferator-activated receptors γ (PPARγ) and CCAAT/enhancer binding protein α (C/EBPα) in cocultured adipocytes and inducible nitric oxide synthase (iNOS) in cocultured macrophages, was inhibited by ECT. Additionally, HO-1 expression was induced in cocultured macrophages and adipocytes. Silencing of HO-1 expression increased the production of NO, TNF-α, and MCP-1 in cocultured cells, in spite of the presence of ECT.
    CONCLUSIONS:
    This study demonstrated that ECT exhibited anti-inflammatory properties by inhibiting the production of proinflammatory cytokines in the interaction between adipocytes and macrophages through HO-1 expression. ECT may have the potential to improve chronic inflammation in obesity.

    Esculetin suppresses proteoglycan metabolism by inhibiting the production of matrix metalloproteinases in rabbit chondrocytes.[Pubmed: 10334506]
    The possible mechanism of the chondroprotective effect of 6,7-dihydroxycoumarin (esculetin) was investigated using primary cultures of rabbit articular chondrocytes.
    METHODS AND RESULTS:
    Esculetin (EST) significantly suppressed the proteoglycan depletion and the release of pulse-labeled [35S]proteoglycan from the matrix layer of rabbit chondrocytes treated with recombinant human interleukin-1alpha. The matrix metalloproteinase inhibitor, 1,10-phenanthroline, also blocked the proteoglycan depletion and [35S]proteoglycan release. From these results, it is likely that recombinant human interleukin-1alpha-induced proteoglycan depletion is mediated by matrix metalloproteinases. Although esculetin did not directly inhibit collagenolytic activity in the culture media, it significantly suppressed the production of pro-matrix metalloproteinase-1/interstitial procollagenase and pro-matrix metalloproteinase-3/prostromelysin 1, accompanied by a decrease in the steady-state levels of their mRNAs.
    CONCLUSIONS:
    These results suggest that esculetin is a therapeutically effective candidate for inhibition of cartilage destruction in osteoarthritis and rheumatoid arthritis.
