Description: H₁ antagonist. Also K_V11.1 (hERG) and K_ir6 (K_ATP) channel blocker

Chemical Name: α-[4-(1,1-Dimethylethyl)phenyl]-4-(hydroxydiphenylmethyl)-1-piperidinebutanol

Purity: ≥98% (HPLC)

Biological Activity Technical Data Solubility Calculators Datasheets References

Biological Activity

Histamine H₁ receptor antagonist. Also blocks K_V11.1 (hERG) and K_ir6 (K_ATP) channels (IC₅₀ values are 204 nM and 1.2 μM respectively). Inhibits the delayed rectifier K⁺ current (I_Kr) in guinea pig ventricular myocytes (IC₅₀ = 50 nM). Activity prolongs QT and induces Torsades de pointes (TdP); cardiotoxic in vivo.
