Title: Discovery of a selective M₄ positive allosteric modulator based on the 3-amino-thieno[2,3-b]pyridine-2-carboxamide scaffold: development of ML253, a potent and brain penetrant compound that is active in a preclinical model of schizophrenia.

Abstract: Herein we report a next generation muscarinic receptor 4 (M(4)) positive allosteric modulator (PAM), ML253 which exhibits nanomolar activity at both the human (EC(50)=56 nM) and rat (EC(50)=176 nM) receptors and excellent efficacy by the left-ward shift of the ACh concentration response curve (fold shift, human=106; rat=50). In addition, ML253 is selective against the four other muscarinic subtypes, displays excellent CNS exposure and is active in an amphetamine-induced hyperlocomotion assay.
