Antazoline
Based on 1 Customer Validation
Antazoline (Phenazoline) is a histamine H1 receptor antagonist with anticholinergic and antiviral properties. Antazoline can prevent histamine from acting on target cells through a reversible competition effect on histamine receptor sites of these cells. Antazoline can exert an antiallegic effect and prevent the occurrence of physiological reactions from the effect of blocking as well as inhibiting H1 receptor. Antazoline can effectively reduce HBV DNA in the extracellular supernatant in a dose-dependent manner, with EC50 of 2.910 μmol/L in HepAD38 cells. Antazoline also has a significant inhibitory effect on HBV DNA in the extracellular supernatant of Huh7 cells (EC50 = 2.349 μmol/L). Antazoline has anti-arrhythmic effect in acute myocardial infarctions. Antazoline can be studied in research for cardiovascular diseases, and HBV.

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
