Eprazinone dihydrochloride is a gent with mucolytic, secretolytic, antitussive, and bronchial antispasmodic properties. Eprazinone dihydrochloride is a neurokinin 1 receptor (NK1R) ligand. Eprazinone dihydrochloride has the potential for chronic bronchitis treatment that improved pulmonary function and arterial partial pressure of oxygen.

Description

IC₅₀ & Target

Neurokinin 1 receptor^[1]

In Vitro

Eprazinone specifically displaces binding to the NK1R. Although Eprazinone displays a rather weak inhibition of [¹²⁵I]BH-SP binding to NK1R, at a concentration of 25 μM, and an antagonistic effect of about 30%, NK1R blockade could contribute to its mucolytic activity^[2].

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

In Vivo

Eprazinone (50-200 mg/kg; oral gavage; daily; for 4 days; adult male rats) at a dose of 200 mg/kg significantly increases total and individual (with the exception of phosphatidylinositol) phospholipid levels and decreases total neutral lipids. Lower doses of Eprazinone significantly decrease neutral lipid levels without affecting the phospholipids^[1].
In airway epithelial studies, mucosal addition of Eprazinone produces a dose-dependent partially reversible decrease in short-circuit current (Isc). The decrease in Isc at lower Eprazinone concentrations is accounted for entirely by a decrease in net chloride secretion while at higher concentrations both sodium and chloride transport are affected^[1].

Animal Model:	Adult male pathogen free Fischer 344 inbred rats (200-250 g)^[1]
Dosage:	50 mg/kg, 100 mg/kg, and 200 mg/kg
Administration:	Oral gavage; daily; for 4 days
Result:	At a dose of 200 mg/kg significantly increased total and individual (with the exception of phosphatidylinositol) phospholipid levels and decreased total neutral lipids.

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% Corn Oil
Solubility: ≥ 6.25 mg/mL (13.78 mM); Clear solution

This protocol yields a clear solution of ≥ 6.25 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 (62.5 mg/mL) to 900 μL Corn oil, and mix evenly.
Protocol 2

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 0.62 mg/mL (1.37 mM); Clear solution

This protocol yields a clear solution of ≥ 0.62 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.2 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 3

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 0.62 mg/mL (1.37 mM); Clear solution

This protocol yields a clear solution of ≥ 0.62 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.2 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.
