Is 4-aminopyridine a repellent?
4-AP is considered an effective bird repellent because as a flock feeds on the treated corn mixture, a small number of birds become symptomatic. Other birds in the flock interpret the symptomatic birds’ signs as a distress call and flee the area.
What is Aminopyridine used for?
4-Aminopyridine (4-AP) is a nonselective blocker of several voltage-sensitive potassium channels. It is used clinically in the symptomatic treatment of demyelinating diseases such as spinal cord injury or multiple sclerosis. It is also used as a bird poison.
How does 4-AP improve MS?
Animal studies show that 4-AP can improve impulse conduction through demyelinated lesions. In patients with MS this translates into improved walking speed and muscle strength of the lower extremities in a subset of patients at a level that is often of clinical relevance.
How does 4-AP work?
It acts by blocking voltage-gated potassium channels, prolonging action potentials and thereby increasing neurotransmitter release at the neuromuscular junction. The drug has been shown to reverse saxitoxin and tetrodotoxin toxicity in tissue and animal experiments.
What are the side effects of Ampyra?

How is 4 aminopyridine used in multiple sclerosis?
Safe and Effective 4-Aminopyridine is Available. 4-aminopyridine (4AP) has been used for many years, prescribed for people with multiple sclerosis. It is a potassium channel blocker that, when used correctly, improves walking and other motor activities.
What is the pKa of 4-aminopyridine pKa?
From literature the pKa’s (more properly from its conjugate acids) of these 2 compounds are: 4-aminopyridine pKa = 9.17. 2-aminopyridine pKa= 6.86.
How is the 4-aminopyridine carboxamide prepared?
4-Aminopyridine is prepared by the decarbonylation of pyridine-4-carboxamide using sodium hypochlorite via the Hofmann rearrangement. The pyridine carboxamide is generated from the corresponding nitrile, which in turn is obtained from ammoxidation of 4-methylpyridine.
