series, compound 1 (PF-06827443), is a potent, low-clearance, orally bioavailable, and CNS-penetrant M1-selective PAM with minimal agonist activity. Compound 1 was tested in dose escalation studies in rats and dogs and was found to induce cholinergic AEs and convulsion at therapeutic indices similar to previous compounds with more agonist activity. These findings provide preliminary evidence that positive

The present invention is directed to pyrazolo [4,3-c] cinnolin-3-one compounds of formula (I) which are M1 receptor positive allosteric modulators and that are useful in the treatment of diseases in which the M1 receptor is involved, such as Alzheimer's disease, schizophrenia, pain or sleep disorders. The invention is also directed to pharmaceutical compositions comprising the compounds, and to the use of the compounds and compositions in the treatment of diseases mediated by the M1 receptor.
Optionally substituted (5- or 7-amino)-3,4-dihydro-(optionally 4-oxo, 4-thioxo or 4- imino)-1H-pyrrolo[3,4-d]pyrimidin-2(6H)-ones, Compounds of Formula (I), processes for their production, their use as pharmaceuticals and pharmaceutical compositions comprising them.
