| Description | Muscarinic receptor ligand. Displays partial agonist activity at M2 and M4 receptors; exhibits antagonist effects at M1, M3 and M5 receptors (Ki values are 2.8, 0.2, 0.6, 0.2 and 0.8 nM respectively). Displays selectivity for muscarinic receptors over a range of neurotransmitter receptors and ion channels. Inhibits firing rate of dopaminergic cells in the limbic ventral tegmental area after acute administration, without binding to dopamine receptors. Purity 98%. MW (observed): 359.46 |
