Description

Asarylaldehyde (Asaronaldehyde), a COX-2 inhibitor, significantly inhibits cyclooxygenase II (COX-2) activity with an IC50 value of 100 μg/mL[1].

IC50 & Target[1]

COX-2

 

In Vitro

Asarylaldehyde (2,4,5-TMBA) is a natural COX-2 inhibitor, which isolated from carrot (Daucus carota L.) seeds significantly inhibits cyclooxygenase II (COX-2) activity at the concentration of 100 μg/mL compared to three commercial nonsteroidal anti-inflammatory drugs Aspinin, Ibuprofen, and Naproxen at their IC50 values 180, 2.52, and 2.06 μg/mL, respectively. 2,4,5-TMBA, a natural inhibitor of cyclooxygenase-2, suppresses adipogenesis and oromotes lipolysis in 3T3-L1 adipocytes. 2,4,5-Trimethoxybenzaldehyde (2,4,5-TMBA) present in plant roots, seeds, and leaves is reported to be a significant inhibitor of cyclooxygenase-2 (COX-2) activity at the concentration of 100 μg/mL. Because COX-2 is associated with differentiation of preadipocytes, the murine 3T3-L1 cells are cultured with 100 μg/mL of 2,4,5-TMBA during differentiation and after the cells are fully differentiated to study the effect of 2,4,5-TMBA on adipogenesis and lipolysis. Oil Red O staining and triglyceride assay revealed that 2,4,5-TMBA inhibited the formation of lipid droplets during differentiation; moreover, 2,4,5-TMBA down-regulated the protein levels of adipogenic signaling molecules and transcription factors MAP kinase kinase (MEK), extracellular signal-regulated kinase (ERK), CCAAT/enhancer binding protein (C/EBP)α, β, and δ, peroxisome proliferator-activated receptor (PPAR)γ, adipocyte determination and differentiation-dependent factor 1 (ADD1), and the rate-limiting enzyme for lipid synthesis acetyl-CoA carboxylase (ACC). In fully differentiated adipocytes, treatment with 2,4,5-TMBA for 72 h significantly decreased lipid accumulation by increasing the hydrolysis of triglyceride through suppression of perilipin A (lipid droplet coating protein) and up-regulation of hormone-sensitive lipase (HSL). When treated with 100 μg/mL of 2,4,5-TMBA for 24, 48, or 72 h, the viability of fully differentiated 3T3-L1 adipocytes is decreased by 8.35, 15.54, and 27.26%, respectively. When the preadiocytes are treated with 100 μg/mL of 2,4,5-TMBA for 24 h before differentiation medium is supplemented, the cell viability is decreased by 26.46%[1]. A COX-2 inhibitor 2,4,5-trimethoxybenzaldehyde (TMBA) is found to be the most abundant constituent, but is totally absent in its cultured broth and its natural host, C. kanehirae wood. 2,4,5-trimethoxybenzaldehyde (TMBA) is the major constituent in fruiting bodies[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% EtOH    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 3.75 mg/mL (19.11 mM); Clear solution

    This protocol yields a clear solution of ≥ 3.75 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (37.5 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% EtOH    90% Corn Oil

    Solubility: ≥ 3.75 mg/mL (19.11 mM); Clear solution

    This protocol yields a clear solution of ≥ 3.75 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 EtOH stock solution (37.5 mg/mL) to 900 μL Corn oil, and mix evenly.

3T3-L1 preadipocytes are seeded into 6-well plates at a concentration of 105/well and cultured in DMEM supplemented with 10% bovine calf serum at 37°C in a humidified atmosphere containing 5% CO2. Two days after confluence, cells are cultured in FBS-containing DMEM (10%, v/v) with the addition of adipogenic factors (0.5 mM IBMX, 1 μM DEX, 5 μg/mL insulin) to induce differentiation (Day 0). Two days later (Day 2), the medium is changed to DMEM supplemented with 10% FBS and 5 μg/mL insulin for another two days. Afterward (Day 4), the medium is changed to DMEM supplemented with 10% FBS only. For the coculture study, 2,4,5-TMBA (0.1 g dissolved in 2 mL of DMSO) is added to the medium from Day 0 to Day 8 (final concentration 100 μg/mL). Control samples are prepared by adding isovolumetric DMSO to the culture medium. For the postculture study, 2,4,5-TMBA is added to the medium on Day 8 (when the cells are fully differentiated) at a final concentration of 100 μg/mL, followed by another 72 h culture. 3T3-L1 cells are seeded in 96-well plates at a concentration of 104/well. Twenty-four hours after seeding, the cells are treated with 100 μg/mL of 2,4,5-TMBA for 24 h or for the whole 8-day differentiation period. Fully differentiated adipocytes are also treated with 100 μg/mL of 2,4,5-TMBA for 24-72 h to test the cytotoxicity. At the end of treatment, cells are cultured with MTT at a final concentration of 0.5 mg/mL for another 4 h. The purple MTT formazan is dissolved by DMSO and the absorbance at 570 nm is taken with a spectrophotometer. The absorbance is proportional to the viability of adipocytes[1].

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.
