Both classical (atropine) and non-traditional (pirenzepine, metacine) antagonists of the muscarinic cholinoreceptors induce, rather than block, an intense and prolonged salivary response in chronically denervated human parotid glands and thus are capable

Calcium Mobilization by Activation of M3/M5 Muscarinic Receptors in the Human Retinoblastoma
Activation of muscarinic acetylcholine receptors (mAChR) is one of the most important signal transduction pathways in the human body. In this study, we investigated the role of mAChR activation in relation to its subtypes in human retinoblastoma cell ...

A 1H nmr study of the amide-bond conformational equilibrium in pirenzepine
The hindered rotation about the exocyclic amide bond of pirenzepine has been studied using 1H nuclear magnetic resonance spectroscopy. The ratios of the two slowly interconverting conformations (1:1·76 at 2 °C and 1:2·37 at 30 °C) and the rate of ...

Pirenzepine affects scleral metabolic changes in myopia through a non-toxic mechanism
Whilst the precise mechanism regulating ocular growth is unknown, it has been shown that various pharmacological agents, including the muscarinic receptor antagonists, atropine and pirenzepine, are effective at preventing the development of myopia.
