In Vivo

Syringaldehyde exerts anti-hyperglycemic effect in rat model of diabetes induced by streptozotocin. Apart from antioxidant capability, Syringaldehyde also has anti-inflammatory activity as it is found to have inhibitory action on cyclo-oxygenase 2 (COX-2) in mouse macrophage cell line[1].

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 (13.72 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 (13.72 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.

Animal Administration

Rats[1]
Adult male albino wistar rats (weighing 180-220 g)
12.5 mg/kg, 25 mg/kg, and 50 mg/kg; p.o.; for 21 days
Adult male albino wistar rats are randomly divided into six groups (n=6), first group serves as control and receives vehicle (orally) for 21 days. Second group is given Syringaldehyde in saline orally at 50 mg/kg for 21 days. Third group receives vehicle for a period of 21 days and then ISO (100 mg/kg, s.c.) on 20th and 21 st day at an interval of 24 h. Fourth group is given Syringaldehyde for 21 days at 12.5 mg/kg, p.o. and ISO on 20th and 21 st day. Fifth group receives Syringaldehyde at concentration of 25 mg/kg, p.o. for 21 days and ISO on 20th and 21 st day. The sixth group is treated with 50 mg/kg of Syringaldehyde for 21 days and ISO on 20th and 21 st day. During the experimental procedure body weight of animals are monitored and on 22nd day, 24 h after second injection of ISO, rats sre sacrificed by cervical decapitation.
Note: Body weight of animals belonging to different groups did not differed significantly but heart weight of ISO challenged animals were highly elevated (p ≤ 0.05) than control rats. However, treatment of rats with Syringaldehyde significantly reduced heart weight in dose dependent way. The rats treated with Syringaldehyde alone displayed an insignificant difference from control group.

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.
