    Description: 13(E)-Labd-13-ene-8alpha,15-diol shows antiviral and anticancer activity, it shows strong anti-HRV2 and HRV3 activity with a 50% inhibitory concentration (IC50) of 2.68 and 0.87 microg/mL,respectively; it also exhibits antilung and antilaryngeal cancer activities against A549 and Hep2 cells.13(E)-Labd-13-ene-8α,15-diol inhibits the growth of the gram-positive bacteria (Staphylococcus aureus, Bacillus cereus and Listeria monocytogenes) and gram-negative bacteria (Vibrio parahaemolyticus, Escherichia coli and Salmonella enteritidis) with a range of minimum inhibitory concentration (MIC) values from 0.092 to 0.598 mg/mL and gram-negative bacteria are more sensitive to the compound (MIC, 0.092 mg/mL).

    Antiviral and anticancer activities of 13(E)-labd-13-ene-8alpha,15-diol isolated from Brachyglottis monroi.[Pubmed: 19504469 ]

    The antiviral activity of 13(E)-labd-13-ene-8alpha,15-diol (Labd-13-ene-8,15-diol,1), isolated from Brachyglottis monroi, was examined against human rhinovirus 2 (HRV2) and 3 (HRV3), and the anticancer activity on human cancer cells (A549 and Hep2). Compound (1) showed strong anti-HRV2 and HRV3 activity with a 50% inhibitory concentration (IC(50)) of 2.68 and 0.87 microg/mL, respectively, and a 50% cytotoxicity concentration (CC(50)) of 59.45 microg/mL. Ribavirin only showed anti-HRV3 activity with an IC(50) of 30.48 microg/mL and a CC(50) > 100 microg/mL. The addition of compound (1) to HRV-infected HeLa cells directly reduced the formation of visible cytopathic effect (CPE) and it directly interacted with HRV particles. Furthermore, A549 and Hep2 cells incubated with 32 microg/mL of compound (1) for 48 h exhibited antilung and antilaryngeal cancer activities, with a viability of less than 50%.
    These results suggest that compound (1) may be used as a potential antiviral and anticancer agent.

    Anticancer and Antimicrobial Activities of 13(E)-labd-13-ene-8α,15-diol from Brachyglottis monroi[Reference: WebLink]
    In a previous study, we reported that 13(E)-labd-13- ene-8α, 15-diol (Labd-13-ene-8,15-diol ,13E) possesses antiviral and anticancer activities.
    In this study, the anticancer and antimicrobial activities of 13(E) were evaluated against 4 cancer cell lines and 6 bacteria. 13(E) showed inhibitory effect on a variety of cancer cell lines. The IC50 values was 8.3-21.3 μg/mL. 13(E) was the most effective growth inhibitor of murine leukaemia cell lines P388, producing approximately 8.3 μg/mL of IC50 in the cytopathic effect (CPE) method. 13(E) also inhibited the growth of the gram-positive bacteria (Staphyl℃℃cus aureus, Bacillus cereus and Listeria mon℃ytogenes) and gram-negative bacteria (Vibrio parahaemolyticus, Escherichia coli and Salmonella enteritidis) with a range of minimum inhibitory concentration (MIC) values from 0.092 to 0.598 mg/mL and gram-negative bacteria were more sensitive to the compound (MIC, 0.092 mg/mL).

    Source: The fruits of Ziziphus jujuba
    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.
