Org 34167 HCl salt is a broad-spectrum inhibitor of HCN channels with IC50 of 23.4, 8.2 and 9.2 uM for HCN1, HCN2 and HCN4 channels, respectively, slowing activation and causing a hyperpolarising shift in voltage-dependence of activation.
MS7710 is a brain-penetrant inhibitor targeting the hyperpolarization-activated cyclic nucleotide-gated (HCN) channels. MS7710 reduces the Ih current and decreases the activity of ventral tegmental area (VTA) dopamine neurons by inhibiting HCN channels. MS7710 can effectively improve social interaction deficits and reward-related cognitive flexibility in the chronic social defeat stress (CSDS) mouse model. MS7710 is promising for research of depression.
NUCC-0200590 is a small-molecule inhibitor of the TRIP8b-HCN interaction with IC50 of 7.0 uM in AlphaScreen assays, effectively disrupts the TRIP8b-HCN interaction in vitro and in vivo.
