Presynaptic effect of the aziridinium ion of acetylcholine mustard (methyl-2-acetoxyethyl-2'-chloroethylamine) on the phrenic nerve--rat diaphragm preparation.

The rat diaphragm has been used to investigate the neuromuscular blocking action of acetylcholine mustard which yields a potent nicotinic agonist, an aziridinium ion, in aqueous medium. Evidence was obtained that the acetylcholine mustard aziridinium ion impaired neuromuscular activity when the phrenic nerve was stimulated and that the ion did not directly… CONTINUE READING
