Deuterium-labeled 4-((2,3-dihydrobenzo[b][1,4]dioxin-6-yl)oxy)piperidines substituted with pyrrolo[3,4-b]pyridin-5-one, furo[3,4-b]pyridin-5(7H)-one, or [1,2,4]triazolo[4,3-a]pyrimidin-3(2H)-one are positive allosteric modulators of the muscarinic acetylcholine receptor M(mAChR M) and may have use in treating neurological and psychiatric disorders associated with muscarinic acetylcholine receptor dysfunction.

Positive modulators of the muscarinic acetylcholine receptor M4

Disclosed herein are analogues of 6-(4-((2,3-dihydrobenzo[b][1,4]dioxin-6-yl)oxy)piperidin-1-yl)-[1,2,4]triazolo[4,3-b]pyridazine, i.e. 7-(4-((phenyl or pyridin-3-yl)oxy)piperidin-1-yl)-4H-pyrimido[1,2-b]pyridazin-4-one derivatives of formula (I) which may be useful as positive allosteric modulators of the muscarinic acetylcholine receptor M(mAChR M). Also disclosed herein are methods of making the compounds, pharmaceutical compositions comprising the compounds, and methods of treating neurological and psychiatric disorders associated with muscarinic acetylcholine receptor dysfunction using the compounds and compositions.

Substituted pyrimido[1,2-b]pyridazines as positive allosteric modulators of the muscarinic acetylcholine receptor M4

6,7-Dihydrothiazolo[5,4-c]pyridines substituted in the 5-position with heterocyclic rings are positive allosteric modulators of the muscarinic acetylcholine receptor M(mAChR M) and may have use in treating neurological and psychiatric disorders associated with muscarinic acetylcholine receptor dysfunction.

Positive allosteric modulators of the muscarinic acetylcholine receptor M4

Disclosed herein are analogues of 6-(4-((2,3-dihydrobenzo[b][1,4]dioxin-6-yl)oxy)piperidin-1 -yl)-[1,2,4]triazolo[4,3-b]pyridazine of formula (Ib), which may be useful as positive allosteric modulators of the muscarinic acetylcholine receptor M(mAChR M). Also disclosed herein are methods of making the compounds, pharmaceutical compositions comprising the compounds, and methods of treating neurological and psychiatric disorders associated with muscarinic acetylcholine receptor dysfunction using the compounds and compositions.

Substituted pyrimido[1,2-b]pyridazines as positive allosteric modulators of the muscarinic acetylcholine receptor M
