Tocris/(<em>R</em>)-(-)-α-Methylhistamine dihydrobromide/0569/10/10 mg-蚂蚁淘生物

Description: Potent, standard H₃ agonist Chemical Name: (R)-(-)-α-Methyl-1H-imidazole-4-ethanamine dihydrobromide Purity: ≥99% (HPLC) Biological Activity Technical Data Solubility Calculators DatasheetsReferences

Biological Activity

Very potent, high affinity H₃ agonist (K_D = 50.3 nM) that displays > 200-fold selectivity over H₄ receptors. Inhibits H₃-mediated histamine synthesis and release in the CNS and stimulates H₄-mediated eosinophil shape change (EC₅₀ = 66 nM). Part of the Histamine H₃ Receptor Tocriset™. (S)-(+)-α-Methylhistamine dihydrobromide (Cat. No. 0572) also available.
