Description

Amygdalin is a plant glucoside isolated from the stones of rosaceous fruits, such as apricots, peaches, almond, cherries, and plums.

In Vitro

Amygdalin has antitumor activity. Some advances had been made on the antitumor mechanism of amygdalin[1]. Amygdalin downregulates especially genes belonging to cell cycle category: exonuclease 1, ATP-binding cassette, sub-family F, member 2, MRE11 meiotic recombination 11 homolog A, topoisomerase (DNA) I, and FK506 binding protein 12-rapamycin-associated protein 1. RT-PCR analysis reveals that mRNA levels of these genes are also decreased by amygdalin treatment in SNU-C4 human colon cancer cells[2].

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

In Vivo

Amygdalin is effective at alleviating inflammatory pain and that it can be used as an analgesic with anti-nociceptive and anti-inflammatory activities. The intramuscular injection of amygdalin significantly reduced the formalin-induced tonic pain in both early (the initial 10 min after formalin injection) and late phases (10-30 min following the initial formalin injection). During the late phase, amygdalin reduces the formalin-induced pain in a dose-dependent manner in a dose range less than 1 mg/kg[3].

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    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (5.47 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

Cell Assay
[2]

Cell viability is determined by MTT assay. Cells are seeded in triplicate at a concentration of 1×105 cells/well on a 96-well plate. SNU-C4 cells are treated with amygdalin at concentrations of 0.25, 0.5, 2.5, and 5 mg/mL for 24 h. After MTT is added to each group, the cells are incubated for 4 h. Then, they are further incubated for 1 h, including the solution in which MTT is dissolved[2].

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

Animal Administration
[3]

Rats: The amygdalin powder is dissolved in saline and diluted with appropriate medium. Male Sprague–Dawley rats weighing 230-250 g are used for this experiment. 50mL of 5% formalin are injected to produce fomalin-induced pain in the rats. Thirty minutes before the formalin injection to induce pain, the rats are given an intramuscular injection of amygdalin solution (0.1, 0.5, 1.0, 10 mg/kg), or saline as a vehicle control[3].

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.
