    Description

    8-Bromo-cGMP sodium, a membrane-permeable analogue of cGMP, is a PKG (protein kinase G) activator. 8-Bromo-cGMP sodium significantly inhibits Ca2+ macroscopic currents and impairs insulin release stimulated with high K+[1]. 8-Bromo-cGMP sodium has antinociceptive effects and results in vasodilator responses[2].

    In Vitro

    8-Bromo-cGMP sodium (1-100 μM; 8 h) increases resistance of LLC-PK1 cells to CsA toxicity concentration-dependently[3].
    8-Bromo-cGMP sodium (1-100 μM; 16 h) induces the synthesis of HO-1 protein in a concentration-dependent fashion[3].

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

    Cell Viability Assay[3]

    Cell Line: LLC-PK1 cells (ATCC CL 101)
    Concentration: 1-100 μM
    Incubation Time: 8 hours
    Result: Increased resistance of LLC-PK1 cells to Cyclosporin A (CsA) toxicity concentration-dependently and augmented cell viability by up to 65%.

    Western Blot Analysis[3]

    Cell Line: LLC-PK1 cells (ATCC CL 101)
    Concentration: 1-100 μM
    Incubation Time: 16 hours
    Result: Induced the synthesis of HO-1 protein in a concentration-dependent fashion.
    In Vivo

    8-Bromo-cGMP sodium (0.3, 1, 3.0 nmol; intrathecal administration; 10 min before test) dose-dependently and significantly increases the tail-flick latency in Vincristine-treated mice to the level observed in vehicle-treated naive mice (male ICR mice, 4weeks of age and weighing 20 g). Vincristine (0.05 mg/kg 1 day after the pre-drug tail-flick latency, and then 0.125 mg/kg twice a week for 6 weeks) can induce painful neuropathy in mice[4].
    8-Bromo-cGMP sodium (10 mg/kg; iv; single dose) results in vasodilator responses in eNOS-Tg mice and WT littermates in C57BL/6 background (19-35 g)[5].

    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.
