NOVEL COMPOUNDS AS SALT-INDUCIBLE KINASES INHIBITORS AND USES THEREOFCROSS-REFERENCE
[0001] This patent application claims the benefit of International Application No. PCT / CN2024 / 097201, filed June 04, 2024; which is incorporated herein by reference in its entirety. FIELD OF THE DISCLOSURE
[0002] The present disclosure relates to novel compounds or pharmaceutically acceptable salts thereof, which are useful as salt-inducible kinases (SIK) inhibitor. The present disclosure further relates to pharmaceutical compositions comprising one or more of such compounds or pharmaceutically acceptable salts thereof as an active ingredient, and use of such compounds or pharmaceutically acceptable salts thereof in the treatment of diseases or disorders.BACKGROUND
[0003] Adenosine monophosphate-activated protein kinases (AMPK) belong to the protein kinase family, which comprises salt-inducible kinases (SIKs) , a family of serine / threonine kinases widely expressed in the body, and involved in particular in cellular energy homeostasis. Three SIK isoforms have been identified, named SIK1 (also referred as SNFI-Like Kinase (SNF1LK) or Myocardial Snfl-like Kinase (MSK) ) , SIK2 (SNF1LK2 or KIAA0781) and SIK3 (KIAA0999) .
[0004] Inhibition of SIK kinases has been demonstrated to result in the concomitant downregulation of pro-inflammatory and the induction of anti-inflammatory molecules. Therefore, the inhibition of the SIKs may result in the suppression of inflammation and the promotion of an immune tolerogenic, anti-inflammatory phenotype; these factors make the SIK family of kinases targets in disease intervention -diseases including inflammatory bowel disease, rheumatoid arthritis, psoriasis, vitiligo and other immune disorders.
[0005] Despite great advances over the past two decades in the treatments of patients affected by autoimmune disorders, based on antibodies targeting pro-inflammatory cytokines such as anti-TNFα, a significant proportion of patients do not respond to these therapies or experience serious adverse events such as opportunistic infections. Therefore, a large unmet medical need still exists for the treatment of these diseases, and new agents for the treatment of the above-mentioned diseases are needed.SUMMARY

[0013] All publications, patents, and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication, patent, or patent application was specifically and individually indicated to be incorporated by reference.DETAILED DESCRIPTIONDefinitions
[0014] In the following description, certain specific details are set forth to provide a thorough understanding of various embodiments. However, one skilled in the art will understand that the invention may be practiced without these details. In other instances, well-known structures have not been shown or described in detail to avoid unnecessarily obscuring descriptions of the embodiments. Unless the context requires otherwise, throughout the specification and claims which follow, the word “comprise” and variations thereof, such as, “comprises” and “comprising” are to be construed in an open, inclusive sense, that is, as “including, but not limited to. ” Further, headings provided herein are for convenience only and do not interpret the scope or meaning of the claimed invention.
[0015] Reference throughout this specification to “some embodiments” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Also, as used in this specification and the appended claims, the singular forms “a, ” “an, ” and “the” include plural referents unless the content clearly dictates otherwise. It should also be noted that the term “or” is generally employed in its sense including “and / or” unless the content clearly dictates otherwise.
[0016] The terms below, as used herein, have the following meanings, unless indicated otherwise.
[0017] Definitions of specific functional groups and chemical terms are described in more detail below. For purposes of this disclosure, the chemical elements are identified in accordance with the Periodic Table of the Elements, CAS version, Handbook of Chemistry and Physics, 75th Ed., inside cover, and specific functional groups are generally defined as described therein. Additionally, general principles of organic chemistry, as well as specific functional moieties and reactivity, are described in Organic Chemistry, Thomas Sorrell, 2nd Edition, University Science Books, Sausalito, 2006; Smith and March March’s Advanced Organic Chemistry, 6th Edition, John Wiley &Sons, Inc., New York, 2007; Larock, Comprehensive Organic Transformations, 3rd Edition, VCH Publishers, Inc., New York, 2018; Carruthers, Some Modern Methods of Organic Synthesis, 4th Edition, Cambridge University Press, Cambridge, 2004; the entire contents of each of which are incorporated herein by reference.
[0018] At various places in the present disclosure, linking substituents are described. Where the structure clearly requires a linking group, the Markush variables listed for that group are understood to be linking groups which may connect to two or more other groups. For example, if the structure requires a linking group and the Markush group definition for that variable lists “alkyl” , then it is understood that the “alkyl” represents a linking alkylene group. For example, the term “alkyl” may connect to one, two or three other group (s) , as required by Markush structures.
[0019] When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom in the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such formula. Combinations of substituents and / or variables are permissible, but only if such combinations result in stable compounds.
[0020] When any variable (e.g., Ri) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-2 Ri moieties, then the group may optionally be substituted with up to two Ri moieties and Ri at each occurrence is selected independently from the definition of Ri. Also, combinations of substituents and / or variables are permissible, but only if such combinations result in stable compounds.
[0021] As used herein, the term “Ci-Cj” indicates a range of the carbon atoms numbers, wherein i and j are integers and the range of the carbon atoms numbers includes the endpoints (i.e. i and j) and each integer point in between, and wherein j is greater than i. For examples, C1-C6 indicates a range of one to six carbon atoms, including one carbon atom, two carbon atoms, three carbon atoms, four carbon atoms, five carbon atoms and six carbon atoms. In some embodiments, the term “C1-12” indicates 1 to 12, particularly 1 to 10, particularly 1 to 8, particularly 1 to 6, particularly 1 to 5, particularly 1 to 4, particularly 1 to 3 or particularly 1 to 2 carbon atoms.

In some embodiments, the compounds described herein are prepared as their individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds, separating the diastereomers and recovering the optically pure enantiomers. In some embodiments, dissociable complexes are preferred. In some embodiments, the diastereomers have distinct physical properties (e.g., melting points, boiling points, solubilities, reactivity, etc. ) and are separated by taking advantage of these dissimilarities. In some embodiments, the diastereomers are separated by chiral chromatography, or preferably, by separation / resolution techniques based upon differences in solubility. In some embodiments, the optically pure enantiomer is then recovered, along with the resolving agent, by any practical means that would not result in racemization. Tautomers
[0100] In some situations, compounds exist as tautomers. The compounds described herein include all possible tautomers within the formulas described herein. Tautomers are compounds that are interconvertible by migration of a hydrogen atom, accompanied by a switch of a single bond and adjacent double bond. In bonding arrangements where tautomerization is possible, a chemical equilibrium of the tautomers will exist. All tautomeric forms of the compounds disclosed herein are contemplated. The exact ratio of the tautomers depends on several factors, including temperature, solvent, and pH.
[0101] Ordinary technicians in this field will understand that a wedged bond or a hashed wedged bond represents the absolute configuration of a chiral center, while a bold bond or a hashed bond represents the relative configuration of a chiral center. Isotopic form
[0102] Unless otherwise stated, compounds described herein may exhibit their natural isotopic abundance, or one or more of the atoms may be artificially enriched in a particular isotope having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number predominantly found in nature. All isotopic variations of the compounds of the present disclosure, whether radioactive or not, are encompassed within the scope of the present disclosure. For example, hydrogen has three naturally occurring isotopes, denoted 1H (protium) , 2H (deuterium) , and 3H (tritium) . Protium is the most abundant isotope of hydrogen in nature. Enriching for deuterium may afford some therapeutic advantages, such as increased in vivo half-life and / or exposure, or may provide a compound useful for investigating in vivo routes of drug elimination and metabolism.
[0103] For example, the compounds described herein may be artificially enriched in one or more particular isotopes. In some embodiments, the compounds described herein may be artificially enriched in one or more isotopes that are not predominantly found in nature.
