    Description: Bruceine E exhibits significant blood glucose concentration reduction activity, it might act as an insulin secretagogue.

    One new pregnane glycoside from the seeds of cultivated Brucea javanica.[Pubmed: 21910051]
    A new pregnane glycoside, named (20R)-O-(3)-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranosyl-pregn-5-en-3β,20-diol (1), and seven known compounds, brusatol (2), bruceine B (3), bruceine D (4), yadanziolide A (5), Bruceine E (6), yadanzioside G (7), and yadanzioside B (8), were isolated from the cultivated dry seeds of Brucea javanica.
    METHODS AND RESULTS:
    The structure of 1 was elucidated on the basis of 1D- and 2D-NMR spectroscopic analyses. Their inhibitory effects on tumor cells were also tested. Compound 1 was slightly active against HL-60, SMMC-7721, A-549, and MCF-7 tumor cells. Compounds 2 and 3 demonstrated significant inhibitory activities against all tested cells.
    CONCLUSIONS:
    These results indicate that cultivated B. javanica could replace the wild plant as an antitumor plant resource.

    Hypoglycemic effect of quassinoids from Brucea javanica (L.) Merr (Simaroubaceae) seeds.[Pubmed: 19439174 ]
    The seeds of Brucea javanica (L.) Merr (Simaroubaceae) are recommended by traditional practitioners for the treatment of diabetes mellitus. To identify the compounds responsible for blood glucose lowering effect and evaluate the acute toxicity of the compounds.
    METHODS AND RESULTS:
    Extracts, fractions and subfractions were administered to normoglycemic mice and the blood glucose concentration was monitored for 8 h. Bioactive compounds isolated through column chromatography were administered to normoglycemic mice and streptozotocin (STZ) rats with monitoring of blood glucose concentration at 0-8h. The acute toxicity was evaluated in mice. Bioactivity-guided fractionation led to the isolation of Bruceine E (1) and bruceine D (2). Normoglycemic mice administered with 1 mg/kg of 1 and 2 exhibited significant blood glucose concentration reduction of 40.07+/-11.45% and 48.82+/-13.34%, respectively. STZ induced diabetic rats administered with 1 and 2 exhibited significant blood glucose concentration reduction of 73.57+/-13.64% and 87.99+/-2.91%, respectively.
    CONCLUSIONS:
    The reduction of blood glucose concentration by both bruceines was comparable to glibenclamide and they might act as an insulin secretagogue. The presence of a hydroxyl moiety at C(2) in 1 reduced the toxic effect by 9-fold compared to 2.
    Bruceine E Description
    Source: The seeds of Brucea javanica (L.) Merr.
    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.
