    生物活性

    Ginkgolic Acid is a natural compound that inhibits SUMOylation with an IC50 of 3.0 μM in in vitro assay.

    IC50 & Target

    IC50: 3.0 μM (SUMOylation)[1]

    体外研究
    (In Vitro)

    Ginkgolic acid inhibits the in vitro SUMOylation of RanGAP1-C2 with the IC50 values of 3.0 μM. The level of SUMOylated p53 is markedly reduced by the ginkgolic acid treatment. Importantly, ginkgolic acid does not affect protein ubiquitination in cells. Ginkgolic acid inhibits the binding between E1 and GA-BODIPY in a dose-dependent manner[1]. Ginkgolic acid (31.2 μg/mL) inhibits HIV protease activity by 60%, compared with the negative control, and the effect is concentration-dependent. Ginkgolic acid treatment (50 and 100 μg/mL) effectively inhibits HIV infection in human PBMC cells. Ginkgolic acid at the concentrations up to 150 μg/mL does not cause any significant cytotoxicity in Jurkat cells[2]. GA only inhibits the growth of tumorogenic cell lines in a both dose- and time-dependent manner. Tumor cells are treated with GA for 72 h, 70.53±4.54% Hep-2 and 63.5±7.2% Tca8113 cells are retarded at GO/G1 phase, and the percentage of apoptosis is 40.4±1.58 and 38.4±1.7%, respectively. GA-treated activated caspase-3 downregulates the expression of anti-apoptotic Bcl-2 protein and upregulates the expression of pro-apoptotic Bax protein, eventually leading to a decrease in the Bcl-2/Bax ratio in tumor cellsin human PBMC cells. Ginkgolic acid at the concentrations up to 150 μg/mL does not cause any significant cytotoxicity in Jurkat cells[3].

    动物实验:

    请根据您的 实验动物和给药方式 选择适当的溶解方案。

    以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
    ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
    以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

    • 方案 一

      请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.75 mg/mL (7.94 mM); 澄清溶液

      此方案可获得 ≥ 2.75 mg/mL(饱和度未知)的澄清溶液。

      1 mL 工作液为例,取 100 μL 27.5 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

      生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。
    • 方案 二

      请依序添加每种溶剂: 10% DMSO    90% Corn Oil

      Solubility: ≥ 2.75 mg/mL (7.94 mM); 澄清溶液

      此方案可获得 ≥ 2.75 mg/mL(饱和度未知)的澄清溶液,此方案实验周期在半个月以上的动物实验酌情使用。

      1 mL 工作液为例,取 100 μL 27.5 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。

    Cell Assay
    [2]

    Jurkat cells (106 cells/mL) are cultured in the RPMI medium with or without different concentrations of ginkgolic acid for 48 hours to test the cytotoxicity of ginkgolic acid. The cytotoxicity of ginkgolic acid is determined using a tetrazolium compound (MTS) and an electron coupling reagent (PMS). MTS is chemically reduced by cells into formazan, which is soluble in the tissue culture medium. The measurement of the absorbance of the formazan can be carried out using 96 well microplates at 492 nm. Since the production of formazan is proportional to the number of living cells, the intensity of the produced color is a good indication of the viability of the cells.

    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.
