4-Aminopyridine kinetics

Clinical Pharmacology and Therapeutics, 1982
Nine healthy subjects (7 men; 2 women) received single 20-mg IV injections of 4-aminopyridine (4-AP). Six of the subjects received the same dose in the form of enteric-coated tablets and four the same dose in uncoated tablets; treatments were at least 2 wk apart.

Aminopyridine-induced seizure activity

Electroencephalography and Clinical Neurophysiology, 1979
Typical seizure activity can be induced by applying 3-aminopyridine to the surface of the cat cortex. The well known characteristics of epileptiform discharges were readily observed by simultaneous recording from both the surface and deeper layers.

6-Aminopyridine-3-thiol

Acta Crystallographica Section C Crystal Structure Communications, 2002
The title compound, C(5)H(6)N(2)S, is a simple but novel pyridinethiol of pharmacological interest. The molecule is planar. The crystal packing is dominated by hydrophobic contacts and a pair of hydrogen-bond interactions between the amino group of one pyridine molecule and the ring N atom of a neighbouring base, stabilizing the structure.

Positron annihilation studies in solid 2-aminopyridine, 3-aminopyridine, 4-aminopyridine and 2-aminopyrimidine

Chemical Physics Letters, 1985
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, 1975
Geometry 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°
