Description

Compounds, pharmaceutical compositions comprising the same, and methods of making and using the same

[0001] This application claims priority to PCT International Patent Application PCT / CN2025 / 082368 filed March 13, 2025, and to Chinese Patent Application CN202511774322.6 filed November 28, 2025, the entire contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0002] The present application relates to a compound, a pharmaceutical composition comprising the same, a method of making the same, and use of the same for preventing or treating a muscarinic acetylcholine receptor M4 mediated disease or condition. BACKGROUND

[0003] Muscarinic acetylcholine receptors are G protein-coupled receptors (GPCRs) and are divided into five subtypes, M1, M2, M3, M4, and M5. These subtypes are widely distributed throughout the peripheral and central nervous systems, with M1 and M4 subtypes mainly expressed in the CNS, with M4 receptors mainly expressed in the cerebral cortex, striatum, hypothalamus, and hippocampus (Neuropharmacology 2018, 136, 362-373). M1, M3, and M5 subtypes are mainly coupled to Gq and activate phospholipase C, while M2 and M4 subtypes are mainly coupled to Gi / o and related effector systems.

[0004] A genome-wide association study for schizophrenia identified a single nucleotide polymorphism at locus rs7951870 significantly associated with disease, which includes the M4 gene (Nature genetics 2018, 50, 381-389). In schizophrenia, the high dopaminergic state in the striatum and nucleus accumbens is associated with psychosis, which is the target of current antipsychotic drugs that block dopamine D2 receptors.

[0005] In a recent study, it was demonstrated that M4 PAMs (M4 positive allosteric modulators) reduced amphetamine-induced dopamine release in the striatum of wild-type mice, but not in M4 knockout wild-type mice (Neuropsychopharmacology 2014, 39, 1578). Another study showed that M4 PAMs induced inhibition of glutamate excitatory synaptic transmission at Schaffer collateral-CA1 synapses in the hippocampus (Hippocampus 2017, 27, 794-810). It was shown that M4 PAMs potentiated the effects of the endogenous agonist acetylcholine, revealing the importance of these receptors in controlling dopamine release in the striatum, and their role in key synapses in the hippocampus that are important for cognition. By activating striatal and hippocampal M4 receptors using specific PAMs, it is possible to reduce the hyperdopaminergic state of the striatum and overstimulation of the hippocampus, providing a treatment for the positive and cognitive symptoms of schizophrenia.

[0006] Eli Lilly disclosed a patent for thienopyridine compounds as positive allosteric modulators (M4 PAMs) for muscarinic M4 acetylcholine receptors (WO2006047124A1). Vanderbilt University has disclosed several international patent applications for muscarinic M4 PAMs

[0007] CVL-231 developed by Pfizer for M4 PAMs is currently in clinical phase II, showing good therapeutic effect on schizophrenic patients. However, there is still a defect of fast metabolism, and the pharmacokinetic properties have room for further improvement.

[0008] Recently, clinical studies on patients with Alzheimer's disease have shown that M1 / M4 agonists, such as xanomeline, activate muscarinic receptors to improve cognitive and psychotic symptoms, such as hallucinations, delusions, and vocalizations (Arch Neurol 1997, 54, 465-73). Therefore, M4 PAMs can improve cognitive deficits and reduce psychotic symptoms in patients with Alzheimer's disease. The combination therapy of xanomeline and trospium (KarXT) has achieved positive results in the treatment of schizophrenia, further demonstrating the therapeutic effect of M receptor agonism in this field. However, xanomeline itself is not well selective for M receptors, and it has strong gastrointestinal side effects in clinical use, which must be combined with a peripheral M2, M3 antagonist for use, which brings inconvenience to clinical application.

[0009] Modulating M4 receptor activity is a promising therapeutic strategy for treating or preventing M4-mediated diseases or conditions. It is necessary to provide new compounds, formulations, treatments, and therapies for treating or preventing M4-mediated diseases or conditions. Therefore, there is a need to develop new compounds that modulate M4 receptor activity to meet the clinical needs. SUMMARY

[0010] This invention provides a novel polycyclic compound that can act as a modulator of muscarinic acetylcholine receptor M4 activity, especially a positive allosteric modulator (M4 PAM), and can be used to treat M4 receptor-mediated diseases or disorders. The compound has excellent positive allosteric modulation of M4 and has fewer toxic side effects and good pharmacokinetic properties.

[0083] Those skilled in the art will understand that not all nitrogen-containing heterocycles can form N-oxides because nitrogen requires available lone pairs of electrons to be oxidized to oxides. Those skilled in the art will identify nitrogen-containing heterocycles capable of forming N-oxides. Those skilled in the art will also recognize that tertiary amines can form N-oxides. Synthetic methods for preparing N-oxides of heterocycles and tertiary amines are well known to those skilled in the art, including but not limited to the oxidation of heterocycles and tertiary amines using peroxy acids such as peracetic acid and m-chloroperoxybenzoic acid (MCPBA), hydrogen peroxide, alkyl peroxides such as tert-butyl peroxide, sodium perborate, and dioxiranes such as dimethyldioxirane. These methods for preparing N-oxides have been extensively described and reviewed in the literature, see, for example: T.L. Gilchrist, Comprehensive Organic Synthesis, vol. 7, pp. 748-750; A.R. Katritzky and A.J. Boulton, Eds., Academic Press; and G.W. H. Heeseman and E.S. G. Wierstiuk, Advances in Heterocyclic Chemistry, vol. 22, pp. 390-392, A.R. Katritzky and A.J. Boulton, Eds., Academic Press.

[0084] The scope of this invention also includes metabolites of the compounds of this invention, i.e., substances formed in the body when the compounds of this invention are administered. Such products can be generated, for example, by oxidation, reduction, hydrolysis, amidation, deamidation, esterification, enzymatic hydrolysis, etc., of the administered compound. Therefore, this invention includes metabolites of the compounds of this invention, including compounds obtained by methods that expose the compounds of this invention to mammals for a time sufficient to produce their metabolites.

[0085] This invention further includes, within its scope, prodrugs of the compounds of this invention, which are certain derivatives of the compounds of this invention that may themselves have little or no pharmacological activity, and which, when administered to or onto the body, can be converted, for example, by hydrolysis and cleavage into the compounds of this invention having the desired activity. Typically, such prodrugs are functional group derivatives of the compounds that are readily converted in vivo into the compounds with the desired therapeutic activity. Further information regarding the use of prodrugs can be found in “Pro-drugs as Novel Delivery Systems,” Vol. 14, ACS Symposium Series (T. Higuchi and V. Stella). The prodrugs of this invention can be prepared, for example, by replacing suitable functional groups present in the compounds of this invention with certain portions known to those skilled in the art as “pro-moiety” (e.g., as described in “Design of Prodrugs,” H. Bundgaard (Elsevier, 1985)).

[0086] This invention also covers compounds of the invention containing protecting groups. In any process of preparing the compounds of the invention, protection of sensitive or reactive groups on any relevant molecule may be necessary and / or desired, thereby forming a form of chemical protection for the compounds of the invention. This can be achieved by conventional protecting groups, for example, those described in T.W. Greene & P. ​​G. W. M. Uts, *Protective Groups in Organic Synthesis*, John Wiley & Sons, 1991, which are incorporated herein by reference. Protecting groups can be removed at appropriate subsequent stages using methods known in the art.
