Biological Activity for Zatebradine hydrochloride

Zatebradine hydrochloride is a bradycardic agent that produces use-dependent inhibition of hyperpolarization-activated current I_f (HCN channel) in sinoatrial node cells (EC₅₀ = 480 nM) and Purkinje fibres. Displays negative chronotropic activity in isolated guinea pig atria (EC₅₀ of 13.4 μM).
