The hexamethonium derivative W84 (hexamethylene-bis-[dimethyl-(3-phthalimidopropyl)-ammonium bromide]) combined with atropine has an overadditive protective action against organophosphorus intoxications. It affects allosterically the binding of (-) [3H]N-methylscopolamine [(3H]NMS) to muscarinic cholinoceptors. Because nicotinic receptors are involved in organophosphorus intoxications, the interaction of

Using the program Microsoft EXCEL, a spreadsheet was developed for constrained, simultaneous analysis of multiple datasets obtained from equilibrium binding experiments, according to an allosteric model of interaction. This approach was used to quantitate the interaction between the modulator (heptane-1,7-bis

W84 (hexamethylene-bis-[dimethyl-(3-phthalimidopropyl)-ammonium bromide]) protects overadditively against an organophosphate-intoxication when applied in combination with atropine. Further experimental evidence led to the hypothesis that W84 exerted an allosteric effect on muscarinic acetylcholine receptors. In order to investigate the action of W84 on

The 2nd outer loop (o2) of muscarinic acetylcholine receptors (mAChRs) contains a highly conserved cysteine residue that is believed to participate in a disulfide bond and is flanked on either side by epitopes that are critical to the binding of
C Tränkle et al.
Molecular pharmacology, 54(1), 139-145 (1998-07-11)
Muscarinic acetylcholine receptors bind allosteric modulators at a site apart from the orthosteric site used by conventional ligands. We tested in cardiac tissue whether modulator binding to ligand-occupied muscarinic M2 receptors is a preferential event that can be detected using
