Biological Data

Biological description

4-Aminopyridine (4-AP) is a non-selective voltage gated K+ channel blocker which blocks Kv1.1 and Kv1.2 channels (IC50 values are 170 and 230 µM respectively).

4-aminopyridine facilitates synaptic and neuromuscular transmission.

4-AP shows proconvulsive actions.
