Naphazoline (Naphthazoline) nitrate is an α-adrenergic receptor agonist. Naphazoline nitrate reduces vascular hyperpermeability and promotes vasoconstriction. Naphazoline nitrate reduces the levels of inflammatory factors (TNF-α, IL-1β and IL-6), cytokines (IFN-γ and IL-4), IgE, GMCSF, and NGF. Naphazoline nitrate can be used for non-bacterial conjunctivitis research.

Description

Naphazoline (Naphthazoline) nitrate is an α-adrenergic receptor agonist. Naphazoline nitrate reduces vascular hyperpermeability and promotes vasoconstriction. Naphazoline nitrate reduces the levels of inflammatory factors (TNF-α, IL-1β and IL-6), cytokines (IFN-γ and IL-4), IgE, GMCSF, and NGF. Naphazoline nitrate can be used for non-bacterial conjunctivitis research[1][2].

In Vivo

Naphazoline nitrate (0.2 mg/kg, 10 μl per eye; IP, once) reduces histamine or antigen-induced conjunctival vascular hyperpermeability in mice, and reduces conjunctivitis in mice via effects on inflammation, NGF and VEGF[1].

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

Animal Model: Female wild-type BALB/c mice (4-5 weeks, 18 ± 2 g, n=8/group, allergic conjunctivitis mouse model established using histamine or an antigen (ovalbumin))[1]
Dosage: 0.2 mg/mL, 10 µl per eye
Administration: Intraperitoneal injection (IP), once
Result: Significantly suppressed conjunctival dye leakage in mice with histamine or antigen‑induced conjunctival vascular hyperpermeability. Reduced inflammatory reactions and the levels of IL-1β, IL-6, IFN-γ, and IL-4. Reduced the levels of IgE, GMCSF, NGF and VEGF in antigen-induced conjunctival vascular hyperpermeability mice.

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 (9.15 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 (9.15 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.

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.
