Cilobradine (Cilo) is a HCN channel blocker with heart rate reducing activity. Cilobradine blocks the slow inward current of human HCN1, HCN2, HCN3, and HCN4 channels. Cilobradine has a slightly higher efficiency in blocking endogenous If in mouse sinoatrial node cells (IC50 value is 0.62μM). Cilobradine can dose-dependently reduce the heart rate from 600 to 200 bpm with an ED50 value of 1.2 mg/kg. Cilobradine induces arrhythmias at doses greater than 5 mg/kg, which are characterized by periodic fluctuations between T waves and P waves.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
