In Vitro

Ethyl gallate is a nonflavonoid phenolic compound and also a scavenger of hydrogen peroxide. After treatment for 24 h or 48 h with Ethyl gallate, HL-60 cells show changes in morphology, including shrinkage of the cell membrane and the development of apoptotic bodies. Consistent with these effects, the viability of Ethyl gallate-treated cells decreases in a time- and dose-dependent manner, demonstrating that Ethyl gallate has a cytotoxic effect on HL-60 cells. Ethyl gallate treatment increases the proportion of cells in subG1 phase in a concentration- and time-dependent manner. Treatment of cells for 24 h or 48 h with 50 μM or 75 μM Ethyl gallate increases the percentage of cells in the subG1 phase from a baseline of 2.9% to 26.5% or 52.6%, respectively. It is found that Ethyl gallate treatment of HL-60 cells decreases the expression of Bcl-2 at 75 μM Ethyl gallate, and increases Bax and truncated Bid (tBid) expression at 24 h[1].

In Vivo

No significant difference in the serum total protein, albumin, globulin and glucose is found between the rats fed with A. nilotica (L.) leaf extract on ethyl gallate equivalent basis and those fed with Ethyl gallate alone. Significant differences in total bilirubin level, however, exist between the rats that receive A. nilotica (L.) leaf extract, 500 mg/kg body weight (ethyl gallate equivalent of 10 mg/kg, 0.34±0.01 mg/dL) and those receiving 10 mg/kg body weight of Ethyl gallate (0.26±0.01 mg/dL). Significant difference is found for ALT between groups fed with 500 and 1000 mg/kg body weight of A. nilotica (L.) leaf extract (26.52±1.23 and 30.05±1.38 U/L) and 10 and 20 mg/kg of Ethyl gallate (20.50±0.94 and 24.67±1.13 U/L)[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 (12.62 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% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (12.62 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Kinase Assay
[1]

The expression of apoptosis-related proteins (caspases-8, -9, -3; AIF; Endo G; Bid; Bax; and Bcl-2) in HL-60 cells is determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of lysates followed by western blotting. For this, HL-60 cells (1.5×106) are treated with 50 μM or 75 μM Ethyl gallate for 6 h, 12 h, or 24 h. Total cell lysates are obtained by resuspending cells in ice-cold radioimmunoprecipitation assay (RIPA) buffer for 30 min followed by centrifugation. Protein concentration is determined using a NanoDrop spectrophotometer. Aliquots of lysates (100 μg protein equivalents) are resolved by 12% SDS-PAGE and transferred onto nitrocellulose membranes[1].

Cell Assay
[1]

HL-60 cells (1×106) are treated with 50 μM or 75 μM Ethyl gallate for 24 h or 48 h at 37°C. Cells are then harvested by centrifugation and fixed in 70% ethanol at 4°C for 24 h. Fixed cells are resuspended in PBS containing 40 μg/mL Propidium iodide (PI), 100 μg/mL RNase A, and 0.1% Triton X-100 and incubated in the dark for 30 min at room temperature. Cell cycle distribution is analyzed by flow cytometry on a FACSCalibur. To investigate apoptotic cells, HL-60 cells (1×106) incubated with different concentration of 50 μM, 75 μM and 100 μM Ethyl gallate for 24 h or 48 h at 37°C, and then DAPI staining is conducted. The cells are photographed using a fluorescence microscopy[1].

Animal Administration
[2]

Forty eight female albino Wistar rats of six to eight weeks old are used and divided into eight groups based on their body weights. Group 1 rats serve as control receiving 1.0 mL of the vehicle (0.1% ethanol); Group 2 rats receive A. nilotica (L.) leaf extract (250 mg/kg body weight); Group 3 rats receive A. nilotica (L.) leaf extract (500 mg/kg body weight); Group 4 rats receive A. nilotica (L.) leaf extract (1000 mg/kg body weight); Group 5 rats receive A. nilotica (L.) leaf extract (2000 mg/kg body weight); Group 6 rats receive Ethyl gallate (5 mg/kg body weight); Group 7 rats receive Ethyl gallate (10 mg/kg body weight); Group 8 rats receive Ethyl gallate (20 mg/kg body weight). Body weights are recorded on 0th and 14th day for each group and all rats are decapitated after an overnight fast[2].

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.
