VU10010 is primarily used in neuroscience research as a selective positive allosteric modulator of the M4 muscarinic acetylcholine receptor. Its application is crucial in studying the role of M4 receptors in the central nervous system, particularly in relation to cognitive functions, motor control, and potential therapeutic targets for neurological disorders such as schizophrenia and Parkinson's disease. By enhancing the receptor's activity, VU10010 helps researchers investigate signaling pathways and develop novel treatments for these conditions.
