Description

Homoplantaginin is a flavonoid from a traditional Chinese medicine Salvia plebeia with antiinflammatory and antioxidant properties. Homoplantaginin could inhibit TNF-α and IL-6 mRNA expression, IKKβ and NF-κB phosphorylation.

IC50 & Target

NF-κB[3] IKKβ[3] TNF-α[3]

In Vitro

Homoplantaginin shows IC50 of reduction level of DPPH radical at 0.35 μg/mL. In human hepatocyte HL-7702 cells exposed to H2O2, the addition of 0.1-100μg/mL of homoplantaginin significantly reduces lactate dehydrogenase leakage, and increases glutathione, glutathione peroxidase and superoxide dismutase in supernatant[1]. Homoplantaginin (0.1, 1, 10 μM) dose-dependently reduces expression of toll-like receptor-4 evoked by palmitic acid (100 μM). Homoplantaginin tightly controlls palmitic acid-induced reactive oxygen species to prevent nucleotide-binding domain-like receptor 3 (NLRP3) inflammasome activation by suppressing reactive oxygen species-sensitive thioredoxin-interacting protein, NLRP3, and caspase-1[2]. Pre-treatment of homoplantaginin on human umbilical vein endothelial cells significantly inhibits palmitic acid induced TNF-α and IL-6 mRNA expression, and IKKβ and NF-κB p65 phosphorylation. Homoplantaginin significantly modulates the Ser/Thr phosphorylation of IRS-1, improves phosphorylation of Akt and endothelial nitric oxide synthase, and increases NO production in the presence of insulin[3].

In Vivo

Homoplantaginin(25-100mg/kg) significantly reducesthe increase in serum alanine aminotranseferase and aspartate aminotransferase, decreases the levels of TNF-α and IL-1. The same treatment also reduces the content of thiobarbituric acid-reactive substances, elevates the levels of GSH, GSH-Px and SOD in hepatic homogenate[1]. Homoplantaginin is rapidly absorbed (Tmax=16.00±8.94min), reaching a mean Cmax between 0.77 and 1.27nmol/mL. The absolute oral bioavailability is calculated to be only 0.75%.

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: ≥ 2.08 mg/mL (4.50 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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: 2.08 mg/mL (4.50 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.08 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 (20.8 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.

Cell Assay
[3]

The viability of cultured cells is determined using the MTT assay. Human umbilical vein endothelial cells are exposed to various concentrations of homoplantaginin (0.1, 1, 3, 10, 30, 100 μM) for 48 h. Subsequently, 20 μL of MTT (5 mg/mL) is added to each well for an additional 4 h at 37°C. The supernatant is removed, and DMSO is added to dissolve the formazan crystals. The optical absorbance is measured at 540 nm[3].

Animal Administration
[1][4]

Rats: Homoplantaginin is dissolved in a solution consistingof DMSO, PEG 400, ethanol and normal saline(2:2:3:3, v/v/v/v) at a concentration of 10 mg/mL. The rats are randomly divided into three groups to receive oral administration(150 mg/kg), tail vein injection (15 mg/kg) and peritoneal injectionv (15 mg/kg). Blood samples (approximately 0.5 mL) are collected from the retro-orbital plexus into heparinized microfugetubes at 5, 10, 20, 30, 45, 60, 90, 120, and 180 min after administration. The plasma samples, separated by centrifuging the blood samples at 10,000 rpm[4].

Mice: Homoplantaginin is dissolved in 5% amylum. Homoplantaginin is administered orally by gastric intubation during the experimental period at doses of 25, 50, 100 mg/kg/d, respectively. Eight hours after injection of LPS, the mice are anesthetized with ether and blood samples are collected by exsanguination from the inferior vein. The liver is removed and fixed in formalin for histological analysis[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.
