エピナスチン 塩酸塩
Based on 1 Customer Validation
Epinastine hydrochloride (WAL801 hydrochloride) is a selective and orally active histamine H1 receptor antagonist, CD96/PVR inhibitor and mast cell stabilizer. Epinastine hydrochloride has high affinity for neuronal octopamine receptors in locusts (Ki = 2 nM) and honeybees (Ki = 1.1 nM). Epinastine hydrochloride inhibits TARC, IL-8, and IL-4. Epinastine hydrochloride activates anti-colon cancer immunity and inhibits Substance P (HY-P0201)-induced scratching behavior and increased vascular permeability. Epinastine hydrochloride can be used in the research of allergic diseases.

体外実験
Epinastine (50-100 μM) hydrochloride inhibits histamine release from rat peritoneal mast cells induced by antigen-antibody reaction[1].
Epinastine hydrochloride shows high affinity for neuronal octopamine receptors in locusts (Ki = 2 nM) and honeybees (Ki = 1.1 nM), specifically displaces [3H]NC-5Z binding to these receptors[2].
Epinastine (1-25 μg/mL; 3-24 h) hydrochloride dose- and time-dependently suppresses constitutive and Calcium ionophore-induced IL-8 release from human eosinophils of atopic patients[3].
Epinastine hydrochloride (1 μM; preincubation for 15 min, then incubation for 19 h) tends to inhibit PHA (HY-N7038)-induced IL-4 mRNA expression in peripheral blood mononuclear cells (PBMC) from asthmatic patients[4].
Epinastine hydrochloride (0.1 μM - 10 μM; 24 h) inhibits IgE secretion from rat IgE-producing hybridoma FE-3 cells[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:Human peripheral blood mononuclear cells (PBMC) from asthmatic patients
-
Concentration:1 μM
-
Incubation Time:15 min (preincubation) + 19 h (incubation with PHA/HDM)
-
Result:Tended to inhibit PHA-induced IL-4 mRNA expression (1.26 vs 0.74).
Had no significant effect on HDM-induced IL-4 mRNA expression.
体内実験
Epinastine (2-6 mg/kg; i.p.; 14 days) hydrochloride significantly inhibits tumor growth in C57BL/6N mice bearing MC38 tumors, enhances infiltration and IFN-γ secretion of CD8+ T cells and NK cells in tumor tissues, and has no toxicity to major organs[8].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (7.28 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (7.28 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 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.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.
