    제품 설명

    Thiodigalactoside (TDG) is an orally active and potent galectin (GAL) inhibitor with Kd values of 24 μM, 49 μM for GAL1 and GAL3, respectively[1]. Thiodigalactoside, a non-metabolizable disaccharide, has anti-inflammatory and anti-cancer activity. Thiodigalactoside dramatically reduces body weight gain in diet-induced obese rats[2].

    IC50 & Target

    Kd: 24 μM (GAL1) and 49 μM (GAL3)[1]
    In Vitro

    Thiodigalactoside (TDG; 250 and 500 μM) exhibits dose-dependent reduction of fat accumulation based on triglyceride (TG) content and Oil Red O (ORO) staining[1].

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    Thiodigalactoside Related Antibodies
    In Vivo

    Thiodigalactoside (TDG; 5 mg/kg; IP; once per week for 5 weeks) results in dramatic inhibition of HFD-induced body weight gain[2].
    Thiodigalactoside (5 mg/kg; oral; daily or weekly for 5 weeks) gave less reduction in body weight gain compare with i.p.[2].

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Model: Five-week-old Sprague-Dawley (SD) male rats[2]
    Dosage: 5 mg/kg
    Administration: IP; once per week for 5 weeks
    Result: Resulted in dramatic inhibition of HFD-induced body weight gain by inhibiting adipogenesis and lipogensis as well as by increasing expression of the proteins associated with thermogenesis and energy expenditure.

    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.
