    Description: Jaceosidin has immunosuppressive, anti-oxidative, anti-inflammatory, and anticancer activities, it is also a microglial inhibitor with anti-neuroinflammation activity. Jaceosidin modulates the ERK/ATM/Chk1/2 pathway, leading to inactivation of the Cdc2-cyclin B1 complex, followed by G2/M cell cycle arrest in endometrial cancer cells. Jaceosidin inhibits T cell proliferation and activation, which is closely associated with its potent down-regulation of the IFN-γ/STAT1/T-bet signaling pathway.
    Targets: VEGFR | FAK | PI3K | Akt | NF-kB | p21 | Chk | ATM/ATR | NO | P450 (e.g. CYP17) | IFN-γ | IL Receptor | STAT | TNF-α

    Jaceosidin, isolated from dietary mugwort (Artemisia princeps), induces G2/M cell cycle arrest by inactivating cdc25C-cdc2 via ATM-Chk1/2 activation.[Pubmed: 23274058]
    Jaceosidin, a flavonoid derived from Artemisia princeps (Japanese mugwort), has been shown to inhibit the growth of several human cancer cells, However, the exact mechanism for the cytotoxic effect of jaceosidin is not completely understood.
    In this study, we investigated the molecular mechanism involved in the antiproliferative effect of jaceosidin in human endometrial cancer cells. We demonstrated that jaceosidin is a more potent inhibitor of cell growth than cisplatin in human endometrial cancer cells. In contrast, jaceosidin-induced cytotoxicity in normal endometrial cells was lower than that observed for cisplatin. Jaceosidin induced G2/M phase cell cycle arrest and modulated the levels of cyclin B and p-Cdc2 in Hec1A cells. Knockdown of p21 using specific siRNAs partially abrogated jaceosidin-induced cell growth inhibition. Additional mechanistic studies revealed that jaceosidin treatment resulted in an increase in phosphorylation of Cdc25C and ATM-Chk1/2. Ku55933, an ATM inhibitor, reversed jaceosidin-induced cell growth inhibition, in part. Moreover, jaceosidin treatment resulted in phosphorylation of ERK, and pretreatment with the ERK inhibitor, PD98059, attenuated cell growth inhibition by jaceosidin.
    These data suggest that jaceosidin, isolated from Japanese mugwort, modulates the ERK/ATM/Chk1/2 pathway, leading to inactivation of the Cdc2-cyclin B1 complex, followed by G2/M cell cycle arrest in endometrial cancer cells.

    Natural flavone jaceosidin is a neuroinflammation inhibitor.[Pubmed: 22619052]
    Jaceosidin is a naturally occurring flavone with pharmacological activity. Jaceosidin, as one of the major constituents of the medicinal herbs of the genus Artemisia, has been shown to exert anticancer, anti-oxidative, anti-inflammatory, and immunosuppressive effects. This study was undertaken to determine the effect of jaceosidin on microglia and neuroinflammation.
    Microglia are the innate immune cells in the central nervous system, and they play a central role in the initiation and maintenance of neuroinflammation. We report that jaceosidin inhibits inflammatory activation of microglia, reducing nitric oxide (NO) production and proinflammatory cytokine expression. IC50 for NO inhibition was 27 ± 0.4 μM. The flavone also attenuated microglial neurotoxicity in the microglia/neuroblastoma co-culture. Systemic injection of jaceosidin ameliorated neuroinflammation in the mouse model of experimental allergic encephalomyelitis.
    These results indicate that plant flavone jaceosidin is a microglial inhibitor with anti-neuroinflammation activity.

    Jaceosidin inhibits contact hypersensitivity in mice via down-regulating IFN-γ/STAT1/T-bet signaling in T cells.[Pubmed: 21093428]
    In the present study, we aimed to investigate the immunosuppressive activity of jaceosidin, a flavone isolated from Artemisia vestita, on T lymphocytes both in vitro and in vivo, and further explore its potential molecular mechanism.
    Jaceosidin exerted a significant inhibition on the T cell proliferation and activation induced by concanavalin A (Con A) in a concentration-dependent manner and it also inhibited the secretion of the proinflammatory cytokines such as IL-2, TNF-α and IFN-γ of activated T cells. Further study showed that jaceosidin down-regulated STAT1 activation and T-bet expression in activated T cells. Moreover, in order to investigate the immunosuppressive effect of jaceosidin in vivo, the picryl chloride (PCl)-induced ear contact dermatitis model was performed on BALB/c mice. Jaceosidin significantly ameliorated PCl-induced ear swelling in a dose-dependent manner, which was due to its inhibition of the STAT1/T-bet signaling pathway.
    In summary, these findings suggest that jaceosidin exerts its immunosuppressive effect both in vitro and in vivo through inhibiting T cell proliferation and activation, which is closely associated with its potent down-regulation of the IFN-γ/STAT1/T-bet signaling pathway.
