Allgemeine Beschreibung

4-Aminopyridine (4-AP) blocks the voltage-dependent potassium channels in other nerve membranes. 4-AP is a K+ channel blocker and causes epileptiform activity in in vitro preparations and is a potent convulsant in animals and man.

Anwendung

4-Aminopyridine can be used as:
  • A reactant to prepare pharmacologically important 4-amino-N-pyridin-4-yl-butyramide hydrochloride.
  • A reactant to prepare cinnamic acid derivatives as potent cholinesterase inhibitors.
  • A starting material to prepare aza analogs of batracylin, a topoisomerase II inhibitor.

A new class of heterotricyclic glutamate analogues recently was generated by incorporating structural elements of two excitotoxic marine compounds, kainic acid and neodysiherbaine A. Rather than acting as convulsants, several of these 'IKM' compounds markedly depressed CNS activity in mice.

It has been recently demonstrated that the exposure of naive neuronal cells to light-at the basis of optogenetic techniques and calcium imaging measurements-may alter neuronal firing. Indeed, understanding the effect of light on nongenetically modified neurons is crucial for a
