Description

Maslinic acid can inhibit the DNA-binding activity of NF-κB p65 and abolish the phosphorylation of IκB-α, which is required for p65 activation.

IC50 & Target[1]

p65

 

In Vitro

Maslinic acid (MA) inhibits LPS-induced NF-κB translocation to nucleus and phosphorylation of IκB-α. Maslinic acid has also been reported to suppress NF-κB regulated osteoclastogenesis in bone marrow monocytes and inhibit TNF-α-induced NF-κB activity and its downstream genes’ expression in pancreatic cancer cells. To confirm if the anti-inflammatory effects of olive pomace extracts (OPEs) inRAW264.7 cells can be attributed to Maslinic acid, dose-dependence experiments determined the effective concentration of Maslinic acid to be 10-20 μM. 20 μM Maslinic acid significantly suppresses TNF-α production and inhibits IL-1, IL-6, and COX-2 mRNA expression in RAW 264.7 cell. Maslinic acid (at 10 and 20 μM) significantly suppresses the DNA-binding activity of NF-κB p65 in LPS-induced RAW 264.7 cells. Pretreatment with Maslinic acid significantly reduces the LPS-induced phosphorylation of IκB-α[1].

In Vivo

Paw swelling is alleviated when mice are administered with 200 mg/kg Maslinic acid (MA), significantly suppressing inflammation, compared to the carrageenan induced control group, 4 h after λ-carrageenan injection (0.91±0.51 mm and 1.79±0.4 mm, respectively)[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    90% (20% SBE-β-CD in Saline)

    Solubility: 2.5 mg/mL (5.29 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    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.
  • Protocol 2

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

    Solubility: ≥ 2.5 mg/mL (5.29 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
[1]

RAW 264.7 cells are seeded in 96-well culture plates at a density of 1×105 cells/mL and after incubation for 24 h, are treated with OPE1 (300 μg/mL or 400 μg/mL), OPE2 (20 μg/mL or 40 μg/mL), or Maslinic acid (10 μM or 20 μM) , as well as with/without LPS at the same time. Cell viability i determined using the WST-1 reagent. Briefly, WST-1 reagent (10 μL) is added to each well and incubated for 1h in a humidified incubator. The absorbance of the samples measured at 450 nm (reference wavelength is 750 nm). Viability is expressed as a percentage of the absorbance measured in LPS-treated cells[1].

Animal Administration
[1]

Mice[1]
Five-week-old male Balb/c mice (19-21 g) are housed in a conventional condition and provided with the free access to standard rodent chow and water. Edema is induced by intraplantar injection of 100 μL 1% carrageenan into the hind left paw. Maslinic acid is tested initially at a dose of 200 mg/kg, orally administered 60 min before and after carrageenan injection. Paw thickness is measured using electronic digital calipers, 2, 3, and 4 h following carrageenan treatment. Mice are sacrificed by carbon dioxide inhalation 4 h after carrageenan injection[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.
