Morphine Withdrawal Syndrome Responses to Cholinergic Antagonists and to a Partial Cholinergic Agonist

Nature, 1973
MORPHINE impairs the release of acetylcholine (ACh) at muscarinic and nicotinic sites in the periphery1–3, and within the brain4–8. Paton9 suggested that morphine's ability to impair ACh release might be the origin of the morphine withdrawal reaction. He proposed that ACh could accumulate within cholinergic terminals during habituation to the narcotic ...

Cholinergic antagonists and REM sleep generation.

Brain Research, 1991
In this study we extended our observations on the role of M1 and M2 muscarinic receptors in mediating the cholinergic induction of REM sleep. Cats were chronically implanted with sleep recording electrodes and microinjections of Ringer's or muscarinic antagonists followed by the relatively specific M2 muscarinic agonist, cis-methyl-dioxolane (cisdioxo),

Methylatropine blocks the central effects of cholinergic antagonists

Behavioural Pharmacology, 1994
These studies were conducted in order to establish the dose dependency and relative peripheral versus central activity of four prototypical cholinergic antagonists on the rodent passive avoidance response, a widely used animal model of retention.

Cholinergic antagonists in a solitary wasp venom.

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1986
The venom of the solitary wasp Philanthus triangulum contains a cholinergic antagonist of the nicotinic receptor of the rectus abdominis muscle of the frog, Xenopus laevis. The venom of African P. triangulum contains two different cholinergic factors, a competitive and a non-competitive antagonist. The venom of the European P.

Deoxycholic Acid Conjugates Are Muscarinic Cholinergic Receptor Antagonists

Pharmacology, 2002
In the course of examining the actions of major human bile acids on cholinergic receptors, we discovered that conjugates of lithocholic acid are partial muscarinic agonists. In the present communication, we report that conjugates of deoxycholic acid (DC) act as cholinergic muscarinic receptor antagonists.
