Background:

Cilobradine is an HCN Channel blocker; an open channel blocker of neuronal Ih and related cardiac If channels.Target: HCN Channel blockerCilobradine is a HCN channel blocker that is about 3 times more potent than ZD7288. At a concentration of 10 μM, Cilobradine inhibits WT mHCN2 channel current by 86 ± 2% (n = 5). In contrast, I432A and A425G channel currents were only reduced by 14 ± 1% (n = 4) and 19 ± 2% (n = 8), respectively, by this concentration of Cilobradine. The double mutant (I432A/A425G) channel was even less sensitive to 10 μM Cilobradine (8 ± 2% inhibition; n = 4).
