    Description: Esculin has neuroprotective, anti-oxidative, and anti-apoptotic effects, it is a plant coumarin compound that occur naturally in dietary plants or when supplemented in the diet probably inhibit the survival of E. coli O157 in the gut. Esculin has protective effects on dopamine(DA)-induced cytotoxicity in human neuroblastoma SH-SY5Y cells. Esculin has a protective effect on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice, it can inhibit the Toll-like receptor-2 (TLR2), Toll-like receptor-4 (TLR4), myeloid differentiation primary response gene-88 (MyD88), and nuclear factor-κB (NF-κB) p65 in LPS-induced ALI.
    Targets: TNF-α | TLR | NF-kB | ROS | p53 | Bcl-2/Bax | Caspase

    Anti-apoptotic effect of esculin on dopamine-induced cytotoxicity in the human neuroblastoma SH-SY5Y cell line.[Pubmed: 17904593 ]
    Dopamine (DA), as a neurotoxin, can elicit severe Parkinson's disease-like syndrome by elevating intracellular reactive oxygen species (ROS) levels and apoptotic activity.
    METHODS AND RESULTS:
    In this study, we examined the effect of esculin, which was extracted from Fraxinus sielboldiana blume, on DA-induced cytotoxicity and the underlying mechanism in human neuroblastoma SH-SY5Y cells. Our results suggest that the protective effects of esculin (10(-7), 10(-6) and 10(-5) M) on DA-induced cytotoxicity may be ascribed to its anti-oxidative properties by reducing ROS level, and its anti-apoptotic effect via protecting mitochondrion membrane potential (DeltaPsim), enhancing superoxide dismutaese (SOD) activity and reduced glutathione (GSH) levels, and regulating P53, Bax and Bcl-2 expression. In addition, esculin inhibited the release of cytochrome c and apoptosis-inducing factor (AIF), and the protein expression of activated caspase 3.
    CONCLUSIONS:
    These data indicate that esculin may provide a useful therapeutic strategy for the treatment of progressive neurodegenerative diseases such as Parkinson's disease (PD).

    Esculin Inhibits the Inflammation of LPS-Induced Acute Lung Injury in Mice Via Regulation of TLR/NF-κB Pathways.[Pubmed: 25676436]

    METHODS AND RESULTS:
    In this study, we investigated anti-inflammatory effects of esculin (ESC) on lipopolysaccharide (LPS)-induced acute lung injury (ALI). ALI was induced in mice by intratracheal instillation of LPS, and ESC (20 and 40 mg/kg) was given orally 1 h prior to LPS administration. After 6 h, bronchoalveolar lavage fluid (BALF) and lung tissue were collected. ESC pretreatment decreased LPS-induced evident lung histopathological changes, lung wet-to-dry weight ratio, and lung myeloperoxidase activity. In addition, pretreatment with ESC inhibited inflammatory cells and proinflammatory cytokines including tumor necrosis factor-α (TNF-α), interleukin-1β, and interleukin-6 in BALF. Furthermore, we demonstrated that ESC inhibited the Toll-like receptor-2 (TLR2), Toll-like receptor-4 (TLR4), myeloid differentiation primary response gene-88 (MyD88), and nuclear factor-κB (NF-κB) p65 in LPS-induced ALI.
    CONCLUSIONS:
    The results indicated that the ESC had a protective effect on LPS-induced ALI in mice.

    Effects of esculin and esculetin on the survival of Escherichia coli O157 in human faecal slurries, continuous-flow simulations of the rumen and colon and in calves.[Pubmed: 15137927]
    The human pathogen Escherichia coli O157:H7 is thought to be spread by direct or indirect contact with infected animal or human faeces.
    METHODS AND RESULTS:
    The present study investigated the effects of the plant coumarin esculin and its aglycone esculetin on the survival of a strain of E. coli O157 under gut conditions. The addition of these compounds to human faecal slurries and in vitro continuous-flow fermenter models simulating conditions in the human colon and rumen caused marked decreases in the survival of an introduced strain of E. coli O157. When four calves were experimentally infected with E. coli O157 and fed esculin, the pathogen was detected in five of twenty-eight (18 %) of faecal samples examined post-inoculation, compared with thirteen of thirty-five (37 %) of faecal samples examined from five control calves not fed esculin.
    CONCLUSIONS:
    Coumarin compounds that occur naturally in dietary plants or when supplemented in the diet probably inhibit the survival of E. coli O157 in the gut.
