生物活性

Betahistine dihydrochloride is an orally active histamine H1 receptor agonist and a H3 receptor antagonist[1]. Betahistine dihydrochloride is used for the study of rheumatoid arthritis (RA)[3].

IC50 & Target[1]

H3 Receptor

 

體外研究
(In Vitro)

Betahistine dihydrochloride (0-10 μM) inhibits [125I]iodoproxyfan binding to membranes of CHO (rH3(445)R) and CHO (hH3(445)R) cells with IC50 values of 1.9 μM and 3.3 μM, respectively. Lead to Ki values of 1.4 μM and 2.5 μM, respectively[2].
Betahistine dihydrochloride (0-10 μM) has a regulating function on cAMP formation in CHO (rH3(445)R), CHO (rH3(413)R), and CHO (hH3(445)R) cells. At low concentrations, betahistine behaves an apparent inverse agonist, and progressively enhances cAMP formation with EC50 values of 0.1 nM, 0.05 nM and 0.3 nM, respectively. In contrast, at concentrations higher than 10 nM, betahistine inhibits cAMP formation with an EC50 value of 0.1 μM in CHO (rH3(445)R) and full agonist activity[2].

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

體內(nèi)研究
(In Vivo)

Betahistine dihydrochloride (intraperitoneal or oral administration; 0.1-30 mg/kg; single dose) with acute administration has increased tele-methylhistamine (t-MeHA) levels with an ED50 of 0.4 mg/kg, indicating the inverse agonism. Besides, after acute oral administration, it increases t-MeHA levels with an ED50 of 2 mg/kg in male Swissmice[2].
Betahistine dihydrochloride (oral adminstration; 1 and 5 mg/kg; daily for 3 weeks) attenuates the severity of arthritis and reduces the levels of pro-inflammatory cytokines in the paw tissues of CIA mice[3].

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

Animal Model: Collagen-induced arthritis (CIA) DBA/1 male mouse model[3]
Dosage: 1 mg/kg; 5mg/kg
Administration: Oral adminstration; day 21 to day 42 after a 21-day CIA induction
Result: Ameliorated mouse CIA by decreasing joint destruction.

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.
