HCN Channel

Hyperpolarization-activated cyclic nucleotide–gated (HCN) channels are integral membrane proteins that serve as nonselective voltage-gated cation channels in the plasma membranes of heart and brain cells. HCN channels are sometimes referred to as pacemaker channels because they help to generate rhythmic activity within groups of heart and brain cells. HCN channels are activated by membrane hyperpolarization, are permeable to Na+ and K+, and are constitutively open at voltages near the resting membrane potential.[2] HCN channels are encoded by four genes (HCN1, 2, 3, 4) and are widely expressed throughout the heart and the central nervous system.

Ivabradine hydrochloride

T2535148849-67-6

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.

MS7710

T207039

MS7710 is a brain-penetrant inhibitor of hyperpolarization-activated cyclic nucleotide-gated (HCN) channels. It reduces Ih current by inhibiting HCN channels, thereby decreasing the activity of dopamine neurons in the ventral tegmental area (VTA). MS7710 effectively improves social interaction deficits and reward-related cognitive flexibility in mouse models of chronic social defeat stress (CSDS) and shows promise for depression research.
