Aminopyridine

4-aminopyridine is an aromatic amine that is pyridine bearing a single amino substituent at position 4. An orphan drug in the US, it is used to improve walking in adults with multiple sclerosis. It has a role as an avicide, a potassium channel blocker and an orphan drug. It is an aromatic amine and an aminopyridine Aminopyridines are members of a family of monoamino and diamino derivatives of pyridine, and their principal mechanism of action is dose-dependent blockade of voltage-gated potassium channels, in particular, fast voltage-gated potassium channels. To date, only 2 main broad-spectrum potassium channel

Information in the patent literature suggests many possible uses for 3-aminopyridine, and this chemical is clearly a chemical of commerce. 4-Aminopyridine has various uses, but is most noted as an experimental drug for th Aminopyridine dimer served as a model compound for a Watson-Crick DNA base pair (Fig. 1). Ab initio calculations predicted that a rapid electron-proton transfer (net H-transfer) in the excited state provides an efficient relaxation pathway to the ground state. We identified this pathway experimentally [1], but the dimer lifetime of 55-85 ps indicated either a considerable barrier on the H. 3-Aminopyridine | C5H6N2 | CID 10009 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety.
