Biological Activity

Description Azelastine HCl is a potent, second-generation, selective, histamine receptor antagonist, used in the treatment of rhinitis.
Histamine receptor [1]
In vitro

Azelastine inhibits Ag- and ionomycin-induced TNF-alpha release with IC50 values of 25.7 mM and 1.66 mM, respectively, in a rat mast RBL-2H3 cell line. Azelastine also inhibits TNF-alpha mRNA expression, TNF-alpha protein synthesis and release, and, possibly related to these effects, Ca2+ influx, in Ag-stimulated cells. Azelastine inhibits TNF-alpha release to a greater extent than mRNA expression/protein synthesis and Ca2+ influx in ionomycin-stimulated cells, suggesting that Azelastine inhibits the release process more potently than transcription or production of TNF-alpha by interfering with a signal other than Ca2+. Azelastine added 1 hour after ionomycin stimulation also immediately blocks subsequent release of TNF-alpha, which has been produced in the cells, without affecting Ca2+ influx. Azelastine inhibits ionomycin-induced, but not Ag-induced, protein kinase C translocation to the membranes. [1] Azelastine hydrochloride (Azeptin) dose-dependently suppresses both DNA and protein synthesis in human gingival fibroblasts (HF) and also suppresses blastogenesis of human peripheral blood lymphocytes (PBL). Azelastine hydrochloride (Azeptin) suppresses both inducible nitric oxide synthase-mRNA level and NO generation in mouse peritoneal macrophages. [2] Azelastine inhibits secretion of IL-6, TNF-alpha and IL-8 as well as NF-kappaB activation and intracellular calcium ion levels in normal human mast cells. [3]

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
