    Biological Activity
    Description: Alantolactone, an allergenic sesquiterpene lactone, has significant antitumor effects on malignant tumor cells, it can suppress inducible nitric oxide synthase and cyclooxygenase-2 expression by down-regulating NF-κB, MAPK and AP-1 via the MyD88 signaling pathway in LPS-activated RAW 264.7 cells, and inhibit cell proliferation by interrupting the interaction between Cripto-1 and activin receptor type II A in activin signaling pathway.
    Targets: Caspase | PARP | NF-kB | TNF-α | IkB | p65 | Bcr-Abl | STAT | IL Receptor | P450 (e.g. CYP17) | CDK | Bcl-2/Bax | IKK | MyD88 | COX

    Alantolactone induces apoptosis in chronic myelogenous leukemia sensitive or resistant to imatinib through NF-κB inhibition and Bcr/Abl protein deletion.[Pubmed: 23613107 ]
    Alantolactone, an allergenic sesquiterpene lactone, has recently been found to have significant antitumor effects on malignant tumor cells. Here, we investigated the potential effect of Alantolactone on Bcr/Abl+ imatinib-sensitive and -resistant cells.
    METHODS AND RESULTS:
    Alantolactone treatment resulted in obvious apoptosis in both imatinib-sensitive and -resistant K562 cells, as shown by the increase in Annexin V-positive cells, caspase-3 activation, poly(ADP-ribose) polymerase-1 (PARP-1) cleavage and mitochondrial membrane potential collapse. Alantolactone significantly inhibited NF-κB-dependent reporter gene activity, decreased the DNA-binding activity of NF-ОκB, and blocked TNF-α-induced IκBα phosphorylation. Of interest, the oncogenic Bcr/Abl fusion protein but not its mRNA levels were quickly reduced upon Alantolactone exposure in imatinib-sensitive and -resistant K562 cells. Bcr/Abl knockdown enhanced the apoptosis driven by Alantolactone. Bcr/Abl protein reduction could not be reversed by the addition of proteasome or caspase-3 inhibitors. The overexpression of p65 inhibited Alantolactone-induced apoptosis, whereas p65 or Bcr/Abl silencing enhanced its apoptotic-inducing effect. Furthermore, Bcr/Abl-transfected 32D cells showed more sensitivity to Alantolactone than vector-transfected control cells, and the Bcr/Abl protein was depleted, as observed in K562 cells. Finally, Alantolactone-induced apoptosis was also observed in primary CD34+ CML leukemic cells.
    CONCLUSIONS:
    Collectively, these findings suggest that Alantolactone is a promising potent agent to fight against CML cells via the inhibition of the NF-κB signaling pathway and depletion of the Bcr/Abl protein.

    Mechanism-based inhibition of Alantolactone on human cytochrome P450 3A4 in vitro and activity of hepatic cytochrome P450 in mice.[Pubmed: 25858508]
    Alantolactone (AL), one of the main active ingredients in Inula helenium L., has been included in various prescriptions of traditional Chinese medicine. The effects of Alantolactone on cytochrome P450 (CYP450) were still unclear. This study evaluated the inhibitory effect of Alantolactone on cytochrome P450s in vitro and in vivo.
    METHODS AND RESULTS:
    The inhibitory effects of Alantolactone on the CYPs activity were evaluated in human liver microsomes (HLMs) and recombinant cDNA-expressed enzymes incubation system, and then determined by LC-MS/MS based CYPs probe substrate assay. C57BL/6 mice were treated Alantolactone orally (0, 25, 50, 100mg/kg) for 15 days. The inhibitory effects of Alantolactone on major Cyps in mice were examined at both the mRNA and enzyme activity levels. Alantolactone showed a potent inhibitory effect on CYP3A4 activity with IC50 values of 3.599 (HLMs) and 3.90 (recombinant CYP3A4) μM, respectively. Alantolactone strongly decreased CYP3A4 activity in a dose-dependent but not time-dependent way in HLMs. Results from typical Lineweaver-Burk plots showed that Alantolactone could inhibit CYP3A4 activity noncompetitively, with a Ki value of 1.09μM in HLMs. Moreover, activity of CYP2C19 could also be inhibited by Alantolactone with IC50 of 36.82μM. Other CYP450 isoforms were not markedly affected by Alantolactone. The inhibition was also validated by in vivo study of mice. Alantolactone significantly decreased mRNA expression of Cyp2c and 3a family.
    CONCLUSIONS:
    The study indicates that herb-drug interaction should be paid more attention between Alantolactone and drugs metabolized by CYP3A4.

    Alantolactone from Saussurea lappa Exerts Antiinflammatory Effects by Inhibiting Chemokine Production and STAT1 Phosphorylation in TNF-α and IFN-γ-induced in HaCaT cells.[Pubmed: 25881570]
    Skin inflammation is the most common condition seen in dermatology practice and can be caused by various allergic reactions and certain toxins or chemicals. In the present study, we investigated the antiinflammatory effects of Saussurea lappa, a medicinal herb, and its marker compounds Alantolactone, caryophyllene, costic acid, costunolide, and dehydrocostuslactone in the HaCaT human keratinocyte cell line.
    METHODS AND RESULTS:
    HaCaT cells were stimulated with tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ), and treated with S. lappa or each of five marker compounds. Chemokine production and expression were analyzed by enzyme-linked immunosorbent assay and reverse transcription-polymerase chain reaction, respectively. Phosphorylation of signal transducer and activator of transcription (STAT) 1 was determined by immunoblotting. Stimulation with TNF-α and IFN-γ significantly increased the production of the following chemokines: thymus-regulated and activation-regulated chemokine (TARC): regulated on activation, normal T-cell expressed and secreted (RANTES): macrophage-derived chemokine (MDC): and interleukin-8 (IL-8). By contrast, S. lappa and the five marker compounds significantly reduced the production of these chemokines by TNF-α and IFN-γ-treated cells. S. lappa and Alantolactone suppressed the TNF-α and IFN-γ-stimulated increase in the phosphorylation of STAT1.
    CONCLUSIONS:
    Our results demonstrate that Alantolactone from S. lappa suppresses TNF-α and IFN-γ-induced production of RANTES and IL-8 by blocking STAT1 phosphorylation in HaCaT cells.

    Alantolactone Induces Apoptosis and Cell Cycle Arrest on Lung Squamous Cancer SK-MES-1 Cells.[Pubmed: 25597476]
    Alantolactone, a sesquiterpene lactone compound, has variety of pharmacological properties, including anti-inflammatory and antineoplastic effects.
    METHODS AND RESULTS:
    In our study, Alantolactone inhibited cancer cell proliferation. To explore the mechanisms underlying its antitumor action, we further examined apoptotic cells and cell cycle distribution using flow cytometry analysis. Alantolactone triggered apoptosis and induced cell cycle G1/G0 phase arrest. Furthermore, the expressions of caspases-8, -9, -3, PARP, and Bax were significantly upregulated, while antiapoptotic factor Bcl-2 expression was inhibited. In addition, the expressions of cyclin-dependent kinase 4 (CDK4), CDK6, cyclin D3, and cyclin D1 were downregulated by Alantolactone.
    CONCLUSIONS:
    Therefore, our findings indicated that Alantolactone has an antiproliferative role on lung squamous cancer cells, and it may be a promising chemotherapeutic agent for squamous lung cancer SK-MES-1 cells.
