    Description: Citreorosein is a cAMP phosphodiesterase inhibitor, it has anti-inflammatory effect, inhibits proinflammatory cytokines production through the inhibition of both MAPKs and AKT-mediated IκB kinase (IKK) phosphorylation and subsequent inhibition of transcription factor NF-κB activation. Citreorosein attenuates degranulation and LTC(4) generation through the suppression of multiple step signaling and would be beneficial for the prevention of allergic inflammation.
    Targets: cAMP | NF-kB | PI3K | Akt | COX | JNK | Phospholipase (e.g. PLA) | IkB | ERK | p38MAPK | AP-1 | p65 | IKK

    Citreorosein inhibits degranulation and leukotriene C₄ generation through suppression of Syk pathway in mast cells.[Pubmed: 22395859]
    The aim of this study was to evaluate whether Citreorosein (CIT), a naturally occurring anthraquinone isolated from Polygoni cuspidati (P. cuspidati) radix, modulates degranulation and 5-lipoxygenase (5-LO)-dependent leukotriene C(4) (LTC(4)) generation in mast cells.
    METHODS AND RESULTS:
    Citreorosein suppresses both degranulation and the generation of LTC(4) in a dose-dependent manner in stem cell factor (SCF)-mediated mouse bone marrow-derived mast cells (BMMCs). With regard to its molecular mechanism of action, we investigated the effects of Citreorosein on intracellular signaling and mast cell activation employing BMMCs. Binding of SCF to c-Kit on mast cell membranes induced increases in intrinsic tyrosine kinase Syk activity and activation of multiple downstream events including phosphorylation of phospholipase Cγ (PLCγ), mobilization of intracellular Ca(2+), phosphatidylinositol 3-kinase (PI3K), Akt, MAP kinases (MAPKs), translocation of phospho-phospholipase A(2) (PLA(2)) and 5-LO.
    CONCLUSIONS:
    The results from the biochemical analysis demonstrate that Citreorosein attenuates degranulation and LTC(4) generation through the suppression of multiple step signaling and would be beneficial for the prevention of allergic inflammation.
