    Triptoquinone B Description
    Source: The vines of Tripterygium wilfordii
    Biological Activity or Inhibitors: 1. Triptoquinone B is a novel interleukin-1 inhibitor, shows extremely potent inhibitory activities against interleukin-lα and β releases for human peripheral mononticlear cells.
    2. Triptoquinone B shows the significant immunosuppressive activity.
    Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
    Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

    Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

    Enantiocontrolled total synthesis of the diterpenoids, triptoquinone B, C and triptocallol[Reference: WebLink]
    An efficient and enantiocontrolled synthesis of Triptoquinone B and C, which possess interleukin-1 inhibitory activity, has been accomplished employing the lipase-catalyzed kinetic resolution and a highly diastereoselective radical cyclization as key synthetic steps. In addition, the first total synthesis of triptocallol has been achieved utilizing the same strategy.

    Diterpenoids possessed immunosuppressive activity from Tripterygium hypoglaucum.[Reference: WebLink]
    To study the diterpenoids possessed immunosuppressive activity from Tripterygium hypoglaucum. Methods: The chemical constituents were isolated from the CHCl3 extracts of T. hypoglaucum by repeated column chromatography, including silica gel, Sephadex LH-20, and preparative HPLC. Their structures were elucidated on the basis of spectroscopic studies. The immunosuppressive activity of these compounds was tested using the lymphocyte transformation test. Results: Compounds I-VI were identified as triptobenzene H (I), triptoquinone A (II), Triptoquinone B (IIII), triptoquinone H (IV), triptonediol (V), triptonoterpene (VI). Conclusion: Compound I-III are isolated from this medicinal plant for the first time and all the compounds show the significant immunosuppressive activity.
