Cat. No. 3948
Chemical Name: α-[4-(1,1-Dimethylethyl)phenyl]-4-(h
Biological ActivityHistamine H1 receptor antagonist. Also blocks KV11.1 (hERG) and Kir6 (KATP) channels (IC50 values are 204 nM and 1.2 μM respectively). Inhibits the delayed rectifier K+ current (IKr) in guinea pig ventricular myocytes (IC50 = 50 nM). Activity prolongs QT and induces Torsades de pointes (TdP); cardiotoxic in vivo.
