Biochem/physiol Actions

Talsaclidine aids in promoting the nonamyloidogenic α-secretase pathway in model systems. It is more effective in stimulating muscarinic M 1 receptors than M 2 and M 3 receptors. In anesthetized guinea pigs, talsaclidine has no bronchospastic effects, but it produces contracture in isolated tracheal muscle. Talsaclidine is considered a potential candidate for cholinergic replacement therapy.
Talsaclidine is a M1 selective muscarinic receptor agonist. Concentration-dependently, talsaclidine increases the release of APPs and dose-dependently. Talsaclidine decreases Aβ formation and decreases cerebrospinal fluid Aβ in AD patients.

The aim of the present investigation was to determine the reasons why the muscarinic receptor agonist talsaclidine (WAL 2014 FU, 1-azabicyclo[2.2.2] octane,3-(2-propynyloxy)-, (R)-,(E)-2-butenedioate) is devoid of bronchospastic effects in anaesthetized guinea pigs but causes contracture in isolated tracheal muscle from

Brain amyloid load in Alzheimer's disease (AD) is, at least in genetic forms, associated with overproduction of amyloid beta-peptides (A beta). Thus, lowering A beta production is a central therapeutic target in AD and may be achieved by modulating such

In functional pharmacological assays, talsaclidine has been described as a functionally preferential M1 agonist with full intrinsic activity, and less pronounced effects at M2- and M3 receptors. In accordance with this, cholinomimetic central activation measured in rabbits by EEG recordings
