    生物活性

    Silvestrol is a eukaryotic translation initiation factor 4A (eIF4A) inhibitor isolated from Agave americana Linn.. Silvestrol induces autophagy and caspase-mediated apoptosis[1][2][3].

    IC50 & Target[3]

    eIF4

     

    体外研究
    (In Vitro)

    Silvestrol is a specific eIF4A-targeting translation inhibitor. Silvestrol exhibits significant cytotoxic activity against many human cancer cell lines, such as lung, prostate, and breast cancer with IC50 values ranging from 1 to 7 nM[1].
    ? Silvestrol significantly reduces the number of LNCaP cell colonies. Silvestrol (30 nM, 120 nM) induces apoptosis in LNCaP cells, through the mitochondrial pathway. Apaf-1, Caspase-2, caspase-9, and caspase-10 are involved in Silvestrol-induced apoptosis but caspase-3 and 7 are not[2].
    ? Silvestrol induces caspase-3 activation and apoptotic cell death in a time- and dose-dependent manner. Silvestrol-mediated cell death is attenuated in ATG7-null mouse embryonic fibroblasts (MEFs) lacking a functional autophagy protein[3].
    ? Silvestrol (50 nM) exerts an immediate inhibitory effect and causes near-static cell index compared with the control cells. Silvestrol (6.25 nM) enhances proliferation more than the vehicle control-treated cells, whereas a higher concentration of Silvestrol (50 nM) can inhibit cell proliferation. Silvestrol and episilvestrol display synergistic effects in combination with CDDP[4].

    (In Vivo)

    Silvestrol (1.5 mg/kg, i.p.) does not adversely affect production of human IgG by xenografted B-lymphocytes in mice. Silvestrol significantly prolongs survival compared to vehicle. There is no such lymphocyte infiltration detected in the spleens of any of the Silvestrol-treated mice, and nor do these animals exhibit any other obvious signs of lymphoma upon necropsy[5].

    Mice[5]
    Peripheral blood mononuclear cells (PBMC) are injected intraperitoneally (IP) into SCID mice depleted of murine natural killer (NK) cells by pretreatment (plus weekly re-treatment) with anti-asialo (GM1). Engraftment is confirmed by hu-IgG ELISA. Treatments with vehicle (30% hydroxypropyl-β-cyclodextrin) or Silvestrol (1.5 mg/kg every 48 hr IP) begin 2 weeks post-engraftment[5].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
