Abstract Positron annihilation lifetimes and Doppler-broadened annihilation lines have been measured in solid 2-aminopyridine (2-APY), 3-aminopyridine (3-APY), 4-aminopyridine (4-APY) and 2-aminopyrimidine (2-APYM). The results point to the formation of positronium in the solid pyridines and the yields are discussed in terms of the structures and the

INDO theoretical studies of 4-aminopyridine and protonated 4-aminopyridine
Journal of the Chemical Society, Perkin Transactions 2, 1975Geometry optimized INDO calculations have been performed on 4-aminopyridine (2) and protonated 4-aminopyridine (1) in order to compare their optimized geometries, π-bond orders, C(4)–NH2 rotational barriers, charge densities, and π-electron distributions. It had previously been shown that 4-aminopyridine falls far off a linear correlation of ΔG° and ΔS°

4-Aminopyridine Hydrochloride (Pymadin)
1986Some of the pharmacological actions of aminopyridines have been known for many years (Dohrn 1924; Dingemanse and Wibaut 1928; von Haxthansen 1955; Fastier and MacDowall 1958 a), but it is only since Bulgarian pharmacologists and anaesthetists, on the basis of their experimental and clinical studies, advocated the use of 4-aminopyridine hydrochloride ...
