애플리케이션

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.

생화학적/생리학적 작용

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

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

A class of pharmacologically active substances, known as "specific bradycardic agents", exerts a negative chronotropic influence on cardiac activity, which heavily relies upon a potent blockade of the hyperpolarization-activated cation current in Purkinje fibers. Since the cation conductance activated by

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.
