A study of muscarinic receptor heterogeneity with weak antagonists

European Journal of Pharmacology, 1976
A study of heterogeneity among muscarinic receptors was carried out with new rigid molecules, comprising structures in the fused quinuclidine-valerolactone, quinuclidine-cyclohexenone, quinuclidine-cyclohexanone and quinuclidine-cyclohexane derivatives.

Muscarinic Receptor Subtypes and the Selectivity of Agonists and Antagonists

Pharmacology, 1988
Receptors may be grouped into superfamilies, according to their mechanism. Muscarinic receptors belong to one such superfamily, that of the G-protein coupled receptors. Subtypes of muscarinic receptors may be defined according to their primary amino acid sequence, their mechanism and their pharmacology.

The discovery of AZD9164, a novel muscarinic M3 antagonist

Bioorganic & Medicinal Chemistry Letters, 2011
The optimization of a new series of muscarinic M(3) antagonists is described, leading to the identification of AZD9164 which was progressed into the clinic for evaluation of its potential as a treatment for COPD.

Affinitu profile of the novel muscarinic antagonist guanylpirenzepine

Life Sciences, 1990
The study reports the functional affinity of an amidino derivative of pirenzepine, guanylpirenzepine, for muscarinic receptors mediating relaxation of rat duodenum, inhibition of rabbit vas deferens twitch contraction (both receptors previously classified as M1), guinea pig negative inotropism (M2) and ileal contraction (M3).

THE INTERACTION OF NICOTINIC RECEPTOR ANTAGONISTS AT MUSCARINIC RECEPTORS

Clinical and Experimental Pharmacology and Physiology, 1987
SUMMARY1. The interaction of some neuromuscular blocking drugs such as gallamine, pancuronium and stercuronium with muscarinic receptors has several features which distinguish these compounds from competitive antagonists in functional and binding studies.2. They also differentiate between muscarinic receptors and may produce effects on ion channels.
