Description

4-Aminopyridine (4-AP) is a nonselective K⁺ channel blocker that has been used to characterize and study the blockage of K⁺ channels. Studies show that 4-AP binds from the cytoplasmic side of the cell membrane. Research suggests that 4-AP extends the potentials of unmyelinated and demyelinated fibers, facilitates conduction in fibers blocked by demyelination, and can induce glutamate and neurotransmitter γ-aminobutyric acid (GABA) release.
