Popis

General description

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.

Application

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.
