    Protection against hydrogen peroxide-induced cytotoxicity in PC12 cells by scutellarin.[Pubmed: 15051420 ]
    The present study investigated the protective actions of the antioxidant Scutellarin against the cytotoxicity produced by exposure to H2O2 in PC12 cells. This was done by assaying for MTT (3,(4,5-dimethylthiazole-2-yl)2,5-diphenyl-tetrazolium bromide) reduction and lactate dehydrogenase (LDH) release.
    Reactive oxygen species (ROS) and Ca2+ in cells were evaluated by fluorescent microplate reader using DCFH and Fura 2-AM, respectively, as probes. Lipid peroxidation was quantified using thiobarbituric acid-reactive substances (TBARS). Mitochondrial membrane potential (MMP) was assessed by the retention of rhodamine123 (Rh123), a specific fluorescent cationic dye that is readily sequestered by active mitochondria, depending on their transmembrane potential. The DNA content and percentage of apoptosis were monitored with flow cytometry. Vitamin E, a potent antioxidant, was employed as a comparative agent. Preincubation of PC12 cells with Scutellarin prevented cytotoxicity induced by H2O2. Intracellular accumulation of ROS, Ca2+ and products of lipid peroxidation, resulting from H2O2 were significantly reduced by Scutellarin. Incubation of cells with H2O2 caused a marked decrease in MMP, which was significantly inhibited by Scutellarin. PC12 cells treated with H2O2 underwent apoptotic death as determined by flow cytometric assay. The percentage of this H2O2-induced apoptosis in the cells was decreased in the presence of different concentrations of Scutellarin. Scutellarin exhibited significantly higher potency compared to the antioxidant vitamin E.
    The present findings showed that Scutellarin attenuated H2O2-induced cytotoxicity, intracellular accumulation of ROS and Ca2+, lipid peroxidation, and loss of MMP and DNA, which may represent the cellular mechanisms for its neuroprotective action.

    Scutellarin alleviates interstitial fibrosis and cardiac dysfunction of infarct rats by inhibiting TGFβ1 expression and activation of p38-MAPK and ERK1/2.[Pubmed: 20942814]
    Interstitial fibrosis plays a causal role in the development of heart failure after chronic myocardial infarction (MI), and anti-fibrotic therapy represents a promising strategy to mitigate this pathological process. The purpose of this study was to investigate the effect of long-term administration of Scutellarin (Scu) on cardiac interstitial fibrosis of myocardial infarct rats and the underlying mechanisms.
    Scu was administered to rats that were subjected to coronary artery ligation. Eight weeks later, its effects on cardiac fibrosis were assessed by examining cardiac function and histology. The number and collagen content of cultured cardiac fibroblasts exposed to angiotensin II (Ang II) were determined after the administration of Scu in vitro. Protein expression was detected by Western blot technique, and mRNA levels by quantitative reverse transcription-PCR. The echocardiographic and haemodynamic measurements showed that Scu improved the impaired cardiac function of infarct rats and decreased interstitial fibrosis. Scu inhibited the expression of FN1 and TGFβ1, but produced no effects on inflammatory cytokines (TNFα, IL-1β and IL-6) in the 8 week infarct hearts. Scu inhibited the proliferation and collagen production of cardiac fibroblasts (CFs) and the up-regulation of FN1 and TGFβ1 induced by Ang II. The enhanced phosphorylation of p38-MAPK and ERK1/2 in both infarct cardiac tissue and cultured CFs challenged by Ang II were suppressed by Scu.
    Long-term administration of Scu improved the cardiac function of MI rats by inhibiting interstitial fibrosis, and the mechanisms may involve the suppression of pro-fibrotic cytokine TGFβ1 expression and inhibition of p38 MAPK and ERK1/2 phosphorylation.

    Biological evaluation and molecular docking of baicalin and scutellarin as Helicobacter pylori urease inhibitors.[Pubmed: 25557028]

    Baicalin and Scutellarin effectively suppressed Helicobacter pylori urease in dose-dependent and time-independent manner with IC50 of 0.82±0.07 mM and 0.47±0.04 mM, respectively, compared to AHA (IC50=0.14±0.05 mM). Structure-activity relationship disclosed 4'-hydroxyl gave flavones an advantage to binding with Helicobacter pylori urease. Kinetic analysis revealed that the types of inhibition were non-competitive and reversible with inhibition constant Ki of 0.14±0.01 mM and 0.18±0.02 mM for baicalin and Scutellarin, respectively. The mechanism of urease inhibition was considered to be blockage of the SH groups of Helicobacter pylori urease, since thiol reagents (L,D-dithiothreitol, L-cysteine and glutathione) abolished the inhibitory action and competitive active site Ni(2+) binding inhibitors (boric acid and sodium fluoride) carried invalid effect. Molecular docking study further supported the structure-activity analysis and indicated that baicalin and Scutellarin interacted with the key residues Cys321 located on the mobile flap through S-H·π interaction, but did not interact with active site Ni(2+). Moreover, Baicalin (at 0.59-1.05 mM concentrations) and Scutellarin (at 0.23-0.71 mM concentrations) did not exhibit significant cytotoxicity to GES-1.
    Baicalin and Scutellarin were non-competitive inhibitors targeting sulfhydryl groups especially Cys321 around the active site of Helicobacter pylori urease, representing potential to be good candidate for future research as urease inhibitor for treatment of Helicobacter pylori infection. Furthermore, our work gave additional scientific support to the use of Scutellaria baicalensis in traditional Chinese medicine (TCM) to treat gastrointestinal disorders.

    In vivo effects of scutellarin on the activities of CYP1A2, CYP2C11, CYP2D1, and CYP3A1/2 by cocktail probe drugs in rats.[Pubmed: 25073400]

    Scutellarin and saline were intravenously administered to male Wistar rats via the caudal vein for 7 days consecutively. On the 8th day, the rats were treated with probe drugs of caffeine (10 mg/kg), tolbutamide (10 mg/kg), metoprolol (20 mg/kg), dapsone (10 mg/kg) by intraperitoneal injection, and the blood samples were collected at different times. The probe drugs in the blood samples were measured by ultra performance liquid chromatography mass spectrometer (UPLC-MS/MS) and the changes of the pharmacokinetics parameters of the drugs were observed to evaluate the effects of Scutellarin on the four CYP450 isoforms in rats. The activity of CYP1A2 in rats was inhibited significantly after treatment with Scutellarin by increased caffeine t1/2 (21.76%, P < 0.05), T(max) (43.05%, P < 0.05), C(max) (43.92%, P < 0.01) and AUC(0-infinity) (50.88%, P < 0.01) in the Scutellarin-treated group compared with those of the blank control. The activity of CYP2C11 in rats was inhibited significantly after treatment with Scutellarin by increased tolbutamide t1/2 (16.74%, P < 0.01), T(max) (116.87%, P < 0.05), C(max) (63.78%, P < 0.01) and AUC(0-infinity) (70.61%, P < 0.01) in the Scutellarin-treated group compared with those of the blank control. The activity of CYP3A1/2 in rats was inhibited significantly after treatment with Scutellarin by increased dapsone t1/2 (45.28%, P < 0.05), T(max) (81.55%, P < 0.05), C(max) (155.58%, P < 0.01)and AUC(0-infinity) (176.35%, P < 0.01) in the Scutellarin-treated group compared with those of the blank control. The pharmacokinetic parameters of metoprolol were not significantly changed in the Scutellarin-treated group compared with those of the blank control.
    Scutellarin could significantly inhibit CYP1A2, CYP2C11 and CYP3A1/2 activities in rats in vivo, but had no effects on the activity of CYP2D1.

    Effect of scutellarin on nitric oxide production in early stages of neuron damage induced by hydrogen peroxide.[Pubmed: 15661569 ]
    The aims of the present study were to investigate the regulatory function of Scutellarin on production of nitric oxide (NO) as well as activities of constitutive NO synthase (cNOS) and inducible NO synthase (iNOS) in early stages of neuron damage induced by hydrogen peroxide.
    Direct detection of NO production was performed on primary cultures of living rat neuronal cells with an electrochemical sensor. Hydrogen peroxide significantly increased culture supernatant levels of NO, the total integral value of the defined areas (500-6500 sxpA) reached 3.68 x 10(6). Pre-treatment with Scutellarin, caused the total integral value to decrease in a dose-dependent fashion (3.24 x 10(6), 2.15 x 10(6), 1.84 x 10(6) for groups 10, 50, and 100 uM Scutellarin, respectively). After exposure to 2.0mM hydrogen peroxide for 2h, malondialdehyde (MDA) level, a marker of lipid peroxidation, was remarkably increased. The elevation can be suppressed by Scutellarin. Hydrogen peroxide also caused significant loss of neuron viability. In comparison with the control group, Scutellarin significant attenuated the loss. Results also showed that hydrogen peroxide increased activity of cNOS, which was markedly inhibited by Scutellarin. However, exposure of neuronal cells to hydrogen peroxide did not lead to an increase in iNOS activity.
    In conclusion, our results suggest that NO production, which increased in early stages of neuron damage induced by hydrogen peroxide can be effectively inhibited by Scutellarin. Moreover, our results indicate that increase in NO production is mediated by cNOS.

    Anti-fibrosis effect of scutellarin via inhibition of endothelial-mesenchymal transition on isoprenaline-induced myocardial fibrosis in rats.[Pubmed: 25268717]
    Scutellarin (SCU) is the major active component of breviscapine and has been reported to be capable of decreasing myocardial fibrosis. The aim of the present study is to investigate whether SCU treatment attenuates isoprenaline-induced myocardial fibrosis and the mechanisms of its action.
    Rats were injected subcutaneously with isoprenaline (Iso) to induce myocardial fibrosis and rats in the SCU treatment groups were intraperitoneally infused with SCU (10 mg·kg-1·d-1 or 20 mg·kg-1·d-1, for 14 days). Post-treatment, cardiac functional measurements and the left and right ventricular weight indices (LVWI and RVWI, respectively) were analysed. Pathological alteration, expression of type I and III collagen, Von Willebrand factor, α-smooth muscle actin, cluster of differentiation-31 (CD31), and the Notch signalling proteins (Notch1, Jagged1 and Hes1) were examined. The administration of SCU resulted in a significant improvement in cardiac function and decrease in the cardiac weight indices; reduced fibrous tissue proliferation; reduced levels of type I and III collagen; increased microvascular density; and decreased expression of α-smooth muscle actin and increased expression of CD31, Notch1, Jagged1 and Hes1 in isoprenaline-induced myocardial fibrosis in rats.
    Our results suggest that SCU prevents isoprenaline-induced myocardial fibrosis via inhibition of cardiac endothelial-mesenchymal transition potentially, which may be associated with the Notch pathway.
