应用
DK-AH 269 has been used as a hyperpolarization-activated and cyclic nucleotide-gated channel (HCN) antagonist to study its effects on the inhibition of Ih in HCN-deficient hair cells of mice. It has also been used as an HCN blocker to study its effects on action potential firing in the suprachiasmatic nucleus (SCN) neurons.
生化/生理作用
DK-AH 269 is a bradycardiac agent.
DK-AH 269 (Cilobradine) is an HCN Channel blocker; an open channel blocker of neuronal Ih and related cardiac If channels.

Hyperpolarization-activated nonselective cation channels (Ih channels) play an important role in the control of membrane excitability and rhythmic neuronal activity. The functional relevance of presynaptic Ih channels in regulating synaptic function, however, is not well established. Recently, it has been
