    Scopolin Description
    Source: The herb of Scopolia japonica
    Biological Activity or Inhibitors: 1. Scopolin formation is increased by the enhanced activity of PAL.
    2. Scopolin can reduce the clinical symptoms of rat AIA by inhibiting inflammation and angiogenesis,and this compound may be a potent agent for angiogenesis related diseases and can serve as a structural base for screening more potent synthetic analogs.
    Solvent: Pyridine, Methanol, Ethanol, 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.

    Scopolin isolated from Erycibe obtusifolia Benth stems suppresses adjuvant-induced rat arthritis by inhibiting inflammation and angiogenesis.[Pubmed: 19327410]
    Despite Scopolin is a main coumarin constituent in the stems of Erycibe obtusifolia Benth, a herb drug that has long been utilized in traditional Chinese medicine for the treatment of rheumatoid arthritis, little information is available about the pharmacological activities of this compound. The present study was performed to investigate the anti-rheumatic effects of Scopolin in adjuvant-induced arthritis (AIA) in rats, and explore the underlying mechanisms of action in views of anti-inflammatory and anti-angiogenic properties in the synovial tissues. Scopolin (50, 100 mg/kg), injected intraperitoneally for 10 days from the onset of secondary response, significantly inhibited both inoculated and non-inoculated paw swelling as well as articular index scores in AIA. Meanwhile, the mean body weight of rats treated with Scopolin was higher than that of model group. Rats treated with high dose of Scopolin (100 mg/kg) preserved a nearly normal histological architecture of the joints and showed a significant reduction of the new blood vessels in the synovial tissues. Additionally, Scopolin could reduce IL-6, VEGF and FGF-2 expressions in rat synovial tissues. In conclusion, Scopolin can reduce the clinical symptoms of rat AIA by inhibiting inflammation and angiogenesis, and this compound may be a potent agent for angiogenesis related diseases and can serve as a structural base for screening more potent synthetic analogs.

    Acetylcholinesterase inhibitory activity of scopolin and scopoletin discovered by virtual screening of natural products.[Pubmed: 15566295]
    Scopoletin (1) and its glucoside Scopolin (2) emerged as potential AChE inhibitors by the virtual screening procedure. They were isolated by different chromatographic methods from the medicinal plant Scopolia carniolica Jaqc. and tested in an enzyme assay using Ellman's reagent. They showed moderate, but significant, dose-dependent and long-lasting inhibitory activities. In the in vivo experiments (icv application of 2 micromol) 1 and Scopolin increased the extracellular acetylcholine (ACh) concentration in rat brain to about 170% and 300% compared to basal release, respectively.

    Scopoletin uptake from culture medium and accumulation in the vacuoles after conversion to scopolin in 2,4-D-treated tobacco cells.[Pubmed: 10808071]
    Addition of [14C]-labeled scopoletin showed that scopoletin was taken up by 2,4-D-treated cells and converted to Scopolin, a 7-O-glucoside of scopoletin. This uptake of scopoletin began 6 h after 2,4-D addition to the cells. Experiments using several inhibitors showed that this uptake was energy-dependent. The phenomenon of 2,4-D-stimulated uptake was observed only for 7-hydroxycoumarins, such as scopoletin, umbelliferone and esculetin. To further investigate the site for scopoletin accumulation, we separated the vacuoles from T-13 cells and quantified the coumarin contents in this fraction. Most of the scopoletin in the vacuoles was present as glucoconjugate, Scopolin. Moreover, glucosylation activity was absent from isolated vacuoles and, therefore, is likely to be located in the cytosol. Therefore, we can state that 2,4-D treatment of tobacco cells stimulated scopoletin uptake. The scopoletin was converted into Scopolin in the cytoplasm, and then transferred into the vacuoles.
