Metabolite Identification
Common Name3-Hydroxy-4-aminopyridine
Description3-Hydroxy-4-aminopyridine is a metabolite of dalfampridine. 4-Aminopyridine (fampridine, USAN dalfampridine) is an organic compound with the chemical formula C5H4N–NH2. The molecule is one of the three isomeric amines of pyridine. It is used primarily as a research tool, in characterizing subtypes of potassium channel, and has also been used to manage some of the symptoms of multiple sclerosis, and is indicated for symptomatic improvement of walking in adults with several variations of the disease.
