if channel

Ivabradine hydrochloride (S 16257-2) is a new If inhibitor (IC50: 2.9 μM). Ivabradine Hydrochloride is the hydrochloride salt form of ivabradine, an orally bioavailable, hyperpolarization-activated, cyclic nucleotide-gated (HCN) channel blocker, with negative chronotropic activity. Upon administration, ivabradine selectively binds to the intracellular portion of the HCN channel pore and blocks HCN channels in the pacemaker cells within the sinoatrial (SA) node. This inhibits the If (funny) pacemaker ion current, prevents the inward flow and intracellular accumulation of positively charged ions, reduces pacemaker activity and slows diastolic depolarization.

Cilobradine hydrochloride (DK-AH 269) is an HCN Channel blocker and an open channel blocker of neuronal Ih and related cardiac If channels.

YM758 is an inhibitor of If current channel.

Ivabradine is a potent, orally active HCN (hyperpolarization-activated cyclic nucleotide-gated) channel blocker that inhibits pacemaker current (If). ivabradine decreases heart rate in a dose-dependent manner and does not alter blood pressure. ivabradine has anticonvulsant, anti-ischaemic and anti-anginal effects.

Cilobradine is an HCN Channel blocker; an open channel blocker of neuronal Ih and related cardiac If channels.
