Discovery of Pre-Clinical Candidate VU6008055/ AF98943: A Highly Selective, Orally Bioavailable, and Structurally Distinct Tricyclic M4 Muscarinic Acetylcholine Receptor Positive Allosteric Modulator (PAM) with Robust In Vivo Efficacy
{{output}}
Herein, we report the structure-activity relationship to develop novel tricyclic M4 positive allosteric modulator scaffolds with improved pharmacological properties. This endeavor involved modifying a 5-amino-3,4-dimethylthieno[2,3-c]pyridazine-6-carboxamide c... ...
