Biological Activity for Xanomeline oxalate

Xanomeline oxalate is a functionally biased muscarinic M4 receptor agonist (EC50 values are 14.1 nM, 30.9 nM, 1700 nM, 1800 nM and 8500 nM at M4, M1, M2, M5 and M3 receptors respectively. Binds with similar affinity to all muscarinic acetylcholine receptors (pKi 6.7-7.7) but displays higher efficacy and efficacy-driven selectivity at M4 receptors. Displays a complex pharmacological profile: reversible and wash-resistant binding, resulting in full agonist activity at M1; delayed wash-resistant partial agonist activity at M2; and delayed wash-resistant full agonist activity at M4. Exhibits antipsychotic activity, and improves cognitive deficits and behavioral disturbances in Alzheimer's disease and schizophrenia.
