In Vitro

Gambogic Acid (Beta-Guttiferrin) is a medicinal compound derived from the gamboges resin of the tree, Garcinia hanburyi. Gambogic Acid has documented cytotoxic activity against tumor cell lines in culture, with concentrations required for killing 50% of cells (LD50 of ~1 μM). The activity of Gambogic Acid against the 6 human anti-apoptotic Bcl-2-family proteins is contrasted, using FPAs. Gambogic Acid displaces to various extents FITC-BH3 peptide binding to all 6 proteins, with apparent IC50 1.47 μM for Bcl-XL, 1.21 μM for Bcl-2, 2.02 μM for Bcl-W, 0.66 μM for Bcl-B, 1.06 μM for Bfl-1, and 0.79 μM for Mcl-1[1]. The growth inhibitory effects of Gambogic Acid or Cisplatin (CDDP) on A549, NCI-H460, and NCI-H1299 cells are assessed by the MTT assay after 48 h exposure. A concentration-dependent inhibition of cell growth is observed with Gambogic Acid and CDDP, with IC50s of 3.56±0.36 and 21.88±3.21 μM for A549 cells, 4.05±0.51 and 25.76±4.03 μM for NCI-H460 cells, and 1.12±0.31 μM and 25.21±4.38 μM for NCI-H1299 cells[2].

In Vivo

To further investigate whether Gambogic Acid (Beta-Guttiferrin) synergises CDDP against tumour growth in vivo, A549 tumors are implanted in SCID mice. When mice are treated with CDDP combined with Gambogic Acid, the tumor inhibition rate is 69.3%, whereas those of mice treated with CDDP and GA alone are 57.2% and 29.0%, respectively[2].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (3.98 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (3.98 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Cell Assay
[2]

The in vitro cell viability effects of Gambogic Acid, CDDP alone, or combined treatments are determined by MTT assay. The cells (2×104 cells per mL) are seeded into 96-well culture plates. After overnight incubation, A549 cells are treated with Gambogic Acid (0.44, 0.88, 1.75, 3.5, 7, 10.5 and 14 μM); NCI-H460 cells are treated with Gambogic Acid (0.5, 1, 2, 4, 8, 12 and 16 μM); NCI-H1299 cells are treated with Gambogic Acid (0.125, 0.25, 0.5, 1, 2 and 4 μM). For the combined treatment in NSCLC cells, three sequences are tested: (a) Gambogic Acid followed by CDDP cells are exposed to Gambogic Acid for 48 h, and then after washout of Gambogic Acid, cells are treated with CDDP for an additional 48 h; (b) CDDP followed by Gambogic Acid cells are exposed to CDDP for 48 h, and then after washout of CDDP, cells are treated with Gambogic Acid for an additional 48 h; and (c) concurrent treatment cells are exposed to both Gambogic Acid and ADM for 48 h. The nature of the drug interaction is analysed by using the combination index (CI)[2].

Animal Administration
[2]

Mice[2]
To determine the in vivo antitumour activity of Gambogic Acid combined with CDDP, viable A549 cells (5×106/100 μL PBS per mouse) are subcutaneously injected into the right flank of 7- to 8-week-old male SCID mice. When the average tumor volume reach 100 mm3, the mice are randomly divided into four treatment groups, including control (saline only, n=5), Gambogic Acid (3.0 mg/kg per 2 days, intravenously; n=6), CDDP (4 mg/kg per week, intravenously; n=6), and sequential combination (CDDP treatment one day before Gambogic Acid treatment, n=6). CDDP (4 mg/kg, weekly) is generally administered at doses less than the maximum-tolerated dose in an attempt to allow any additive effects of combination treatment with platinum-based agents and Gambogic Acid to be more easily detected. Tumor size is measured once every 2 days with a calipre. Body weight is recorded once every 2 days. After 14 days, the mice are killed and the tumors are excised and stored at -80 °C until further analysis.

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.
