M1 muscarinic receptor activation mediates cell death in M1-HEK293 cells. [PDF]
HEK293 cells have been used extensively to generate stable cell lines to study G protein-coupled receptors, such as muscarinic acetylcholine receptors (mAChRs).

Flavonoids with M1 Muscarinic Acetylcholine Receptor Binding Activity [PDF]
Muscarinic acetylcholine receptor-active compounds have potential for the treatment of Alzheimer’s disease. In this study, a series of natural and synthetic flavones and flavonols was assayed in vitro for their ability to inhibit radioligand binding at ...

Targeting the M1 muscarinic acetylcholine receptor in Alzheimer’s disease [PDF]
Abstract Alzheimer’s disease (AD) remains a major cause of morbidity and mortality worldwide, and despite extensive research, only a few drugs are available for management of the disease. One strategy has been to up-regulate cholinergic neurotransmission to improve cognitive function, but this approach has dose-limiting adverse effects ...

M1 muscarinic acetylcholine receptor in Alzheimer’s disease [PDF]
The degeneration of cholinergic neurons and cholinergic hypofunction are pathologies associated with Alzheimer's disease (AD). Muscarinic acetylcholine receptors (mAChRs) mediate acetylcholine-induced neurotransmission and five mAChR subtypes (M1-M5) have been identified.

Pre-clinical models, postmortem and neuroimaging studies all support a role for muscarinic receptors in the molecular pathology of schizophrenia. From these data it was proposed that activation of the muscarinic M1 and/or M4 receptor would reduce the ...

Additive interaction of intrathecal ginsenosides and neostigmine in the rat formalin test [PDF]
BackgroundThe authors evaluated the effect of intrathecal mixture of ginsenosides with neostigmine on formalin-induced nociception and made further clear the role of the spinal muscarinic (M) receptors on the activity of ginsenosides.MethodsA catheter ...

Characterization of the positive and negative inotropic effects of acetylcholine in the human myocardium [PDF]
In the human isolated myocardium, acetylcholine (10−9 to 10−3 M) elicited a biphasic inotropic effect (a decrease in the lower and an increase in the higher concentration range) in atrial and a positive inotropic effect in ventricular trabeculae. However,

Molecular Determinants of Allosteric Modulation at the M1 Muscarinic Acetylcholine Receptor [PDF]
Benzylquinolone carboxylic acid (BQCA) is an unprecedented example of a selective positive allosteric modulator of acetylcholine at the M1 muscarinic acetylcholine receptor (mAChR). To probe the structural basis underlying its selectivity, we utilized site-directed mutagenesis, analytical modeling, and molecular dynamics to delineate regions of the M1 ...

Purification and properties of m1-toxin, a specific antagonist of m1 muscarinic receptors [PDF]
The venom of the Eastern green mamba from Africa, Dendroaspis angusticeps, was found to block the binding of 3H-quinuclidinyl benzilate to pure m1 and m4 muscarinic ACh receptors expressed in Chinese hamster ovary cells. The principal toxin in the venom with anti- m1 muscarinic activity was purified by gel filtration and reversed- phase HPLC.
