Did you know?
Methoctramine has been shown to competitively antagonize muscarinic receptors, thus preventing them from binding to the neurotransmitter acetylcholine (and other agonists, such as bethanechol or berberine). At higher concentrations, allosteric properties of methoctramine have also been described. Biochemical literature distinguishes 5 different types of muscarinic receptors, each of one havin… Web5 jan. 1988 · A newly described cardiac selective antagonist methoctramine was examined in direct binding studies for affinity at three putative subtypes of the muscarinic receptor. The compound proved to be highly selective (158 fold) for cardiac as opposed to exocrine gland type M 2 muscarinic receptors.
