Product overview

  • Name
    ZD 7288
  • Short description
    HCN channel blocker. Modulates sino-atrial node function.
  • Biological description

    Hyperpolarization-activated, cyclic nucleotide-gated cation (HCN) channel blocker (IC50 = 15.0 µM).

    Modulates sino-atrial node function; blocks the hyperpolarization-activated inward current If and inhibits Ih in central neurons.

    Also inhibits Na+ currents in dorsal root ganglion neurons (IC50 = 1.17 µM).

    Blocks long term potentiation (LTP) induction and displays anxiolytic properties.

    Also increases doubling time of embryonic stem cells (ESCs) and modulates differentiation outcomes. Active in vivo.
