RT Journal Article SR Electronic T1 THE ACTION OF PYRIDYLACETYLCHOLINE ON NEUROMUSCULAR AND GANGLIONIC TRANSMISSION JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 104 OP 107 VO 123 IS 2 A1 Rubin, A.

YR 1958 UL http://jpet.aspetjournals.org/content/123/2/104.abstract AB Pyridylacetylcholine (PACh) is less active than its analogue imidazoleacetylcholine (ImACh) in inhibiting neuromuscular transmission, but is much more active in stimulating autonomic ganglia. PACh is hydrolyzed less rapidly than ImACh by plasma cholinesterase. Neither PACh nor ImACh is hydrolyzed by acetylchohinesterase.
