AI Technical Summary
Current treatments for obesity and related comorbidities, such as type 2 diabetes and hypertension, are inadequate in promoting significant weight loss without affecting muscle mass and do not effectively manage body composition.
Administering Compound A or Compound B, in conjunction with a GLP-1 receptor modulator, to modulate the APJ receptor and enhance weight loss while preserving muscle mass and reducing fat mass.
This approach results in increased total weight loss, normalizing body composition to lean levels, and decreasing fed glucose levels without reducing calorie intake, achieving muscle-sparing weight loss.

METHODS FOR TREATING OBESITY AND INCREASING WEIGHT LOSSCROSS REFERENCE TO RELATED APPLICATIONS
[0001] The application claims the benefit under 35 U.S.C. § 119(e) to U.S. Provisional Application Number 63 / 563,238, filed March 8, 2024, and the benefit of International Patent Application Number PCT / CN2024 / 080896, filed on March 11, 2024, each of which is incorporated herein by reference in its entirety.FIELD
[0002] The present disclosure relates to methods for treating obesity and / or methods for reducing and maintaining body weight and / or body fat in a patient in need thereof.BACKGROUND
[0003] Obesity is a chronic disease with high prevalence and associated comorbidities, making it a growing global concern. These comorbidities include type 2 diabetes, hypertension, ventilatory dysfunction, arthrosis, venous and lymphatic circulation diseases, depression, and others, which have a negative impact on health and increase morbidity and mortality. Apelin, a peptide hormone, exerts its effect by binding with angiotensin II protein J receptor (APJ) and is considered to be linked with diabetes and obesity. Apelin and its receptor are widely present in the body and are involved in many physiological processes, such as glucose and lipid metabolism, homeostasis, endocrine response to stress, and angiogenesis. GLP-1 agonists, used to treat type 2 diabetes, have been shown to be effective in promoting weight loss in preclinical and clinical studies.SUMMARY
[0004] The compound 7V-(l-(2,6-dimethoxyphenyl)-2-(6-ethoxypyridin-2-yl)-lH-imidazo[4,5- b]pyrazin-6-yl)methanesulfonamide and A-(5-chloro-l-(2,6-dimethoxyphenyl)-2-(6-ethoxypyridin-2-yl)- lH-imidazo[4,5-b]pyrazin-6-yl)methanesulfonamide, designated herein as Compound A and Compound B, respectively, have the following formulas:Compound A Compound B

Thus, the amide containing compounds are understood to include their imidic acid tautomers. Likewise, the imidic acid containing compounds are understood to include their amide tautomers.
[0051] Any compound or structure given herein, is also intended to represent unlabeled forms as well as isotopically labeled forms of the compounds. These forms of compounds may also be referred to as “isotopically enriched analogs.” Isotopically labeled compounds have structures depicted herein, exceptthat one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into the disclosed compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine, chlorine, and iodine, such as2H,3H,11C,13C,14C,13N,15N,15O,170,180,31P,32P,35S,18F,36C1,123I, and125I, respectively. Various isotopically labeled compounds of the present disclosure, for example those into which radioactive isotopes such as3H and14C are incorporated. Such isotopically labelled compounds may be useful in metabolic studies, reaction kinetic studies, detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays or in radioactive treatment of patients.
[0052] The term “isotopically enriched analogs’’ includes “deuterated analogs” of compounds described herein in which one or more hydrogens is / are replaced by deuterium, such as a hydrogen on a carbon atom. Such compounds exhibit increased resistance to metabolism and are thus useful for increasing the half-life of any compound when administered to a mammal, particularly a human. See, for example, Foster. “Deuterium Isotope Effects in Studies of Drug Metabolism,” Trends Pharmacol. Sci. 5( 12): 524-527 (1984). Such compounds are synthesized by means well known in the art, for example by employing starting materials in which one or more hydrogens have been replaced by deuterium.
[0053] Deuterium labelled or substituted therapeutic compounds of the disclosure may have improved DMPK (drug metabolism and pharmacokinetics) properties, relating to distribution, metabolism, and excretion (ADME). Substitution with heavier isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life, reduced dosage requirements, and / or an improvement in therapeutic index. An18F.3H.11C labeled compound may be useful for PET or SPECT or other imaging studies. Isotopically labeled compounds of this disclosure and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent. It is understood that deuterium in this context is regarded as a substituent in a compound described herein.
[0054] Tire concentration of such a heavier isotope, specifically deuterium, may be defined by an isotopic enrichment factor. In the compounds of this disclosure any atom not specifically designated as a particular isotope is meant to represent any stable isotope of that atom. Unless otherwise stated, when a position is designated specifically as “H” or “hydrogen,” the position is understood to have hydrogen at its natural abundance isotopic composition. Accordingly, in the compounds of this disclosure any atom specifically designated as a deuterium (D) is meant to represent deuterium.

In addition, if the compounds described herein are obtained as an acid addition salt, the free base can be obtained by basifying a solution of the acid salt. Conversely, if the product is a free base, an addition salt, particularly a pharmaceutically acceptable addition salt, may be produced by dissolving the free base in a suitable organic solvent and treating the solution with an acid, in accordance with conventional procedures for preparing acid addition salts from base compounds. Those skilled in the art will recognize various synthetic methodologies that may be used to prepare nontoxic pharmaceutically acceptable addition salts. Pharmaceutically acceptable acid addition salts may be prepared from inorganic and organic acids. Salts derived from inorganic acids include, e.g., hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid and the like.

[0059] Polymers or similar indefinite structures arrived at by defining substituents with further substituents appended ad infinitum (e.g., a substituted aryl having a substituted alkyl which is itself substituted with a substituted aryl group, which is further substituted by a substituted heteroalkyl group, etc.) are not intended for inclusion herein. Unless otherwise noted, the maximum number of serial substitutions in compounds described herein is three. For example, serial substitutions of substituted aryl groups with two other substituted aryl groups are limited to ((substituted aryl)substituted aryl) substituted aryl. Similarly, the above definitions are not intended to include impermissible substitution patterns (e.g., methyl substituted with 5 fluorines or heteroaryl groups having two adjacent oxygen ring atoms). Such impermissible substitution patterns are well known to the skilled artisan. When used to modify a chemical group, the term “substituted” may describe other chemical groups defined herein. Unless specified otherwise, where a group is described as optionally substituted, any substituents of the group are themselves unsubstituted. For example, in some embodiments, the term “substituted alkyl” refers to an alkyl group having one or more substituents including hydroxyl, halo, alkoxy, cycloalkyl, heterocyclyl, aryl, and heteroaryl. In other embodiments, the one or more substituents may be further substituted with halo, alkyl, haloalkyl, hydroxyl, alkoxy, cycloalkyl, heterocyclyl, aryl, or heteroaryl, each of which is substituted.

[0167] The compounds of this disclosure can be prepared from readily available starting materials using, for example, the following general methods, and procedures. It will be appreciated that where certain process conditions (i.e., reaction temperatures, times, mole ratios of reactants, solvents, pressures, etc.) are given, other process conditions can also be used unless otherwise stated. Optimum reaction conditions may vary with the reactants or solvent used, but such conditions can be detennined by one skilled in the art by routine optimization procedures.
[0168] Additionally, as will be apparent to those skilled in the art, conventional protecting groups may be necessary to prevent certain functional groups from undergoing undesired reactions. Suitable protecting groups for various functional groups as well as suitable conditions for protecting and deprotecting certain functional groups are well known in the art. For example, numerous protecting groups are described in T. W. Greene and G. M. Wuts (1999) Protecting Groups in Organic Synthesis, 3rd Edition, Wiley, New York, and references cited therein.
[0169] Furthermore, the compounds of this disclosure may contain one or more chiral centers. Accordingly, if desired, such compounds can be prepared or isolated as pure stereoisomers, i.e., as individual enantiomers or diastereomers, or as stereoisomer-enriched mixtures. All such stereoisomers (and enriched mixtures) are included within the scope of this disclosure, unless otherwise indicated. Pure stereoisomers (or enriched mixtures) may be prepared using, for example, optically active starting materials or stereoselective reagents well-known in the art. Alternatively, racemic mixtures of such compounds can be separated using, for example, chiral column chromatography, chiral resolving agents, and the like.
[0170] The starting materials for the following reactions are generally known compounds or can be prepared by known procedures or obvious modifications thereof. For example, many of the starting materials are available from commercial suppliers such as Aldrich Chemical Co. (Milwaukee, Wisconsin, USA), Bachem (Torrance CA USA), EMKA-Chemie Gmbh & Co. KG (Eching Germany), or Millipore Sigma (Burlington MA USA). Others may be prepared by procedures, or obvious modifications thereof, described in standard reference texts such as Fieser and Fieser's Reagents for Organic Synthesis, Volumes 1-15 (John Wiley, and Sons, 1991), Rodd's Chemistry of Carbon Compounds, Volumes 1-5, and Suppiementals (Elsevier Science Publishers, 1989), Organic Reactions, Volumes 1-40 (John Wiley, and Sons, 1991), March's Advanced Organic Chemistry, (John Wiley, and Sons, 5thEdition, 2001), and Larock's Comprehensive Organic Transformations (VCH Publishers Inc., 1989).
[0171] Scheme I illustrates a general method which can be employed for the synthesis of certain compounds described herein, where each Rlf, Q2, R3, R9, RCa, RQA, RQB, RA, w, v, and q are each independently as defined herein, and LG is a suitable leaving group, such as halo (e.g. , hydroxy, alkoxy, halo, etc.).Scheme I
[0172] Compounds of Formula I can be provided by coupling compound 1-A with compound 1-B under suitable coupling reaction conditions, such as amide bond forming reaction conditions ornucleophilic substitution reaction conditions reaction conditions. Further derivatization can be performed of the resulting product via methods and chemical transformations which are known to those of skill in the art can provide alternative compounds of Formula I. For example, when the leaving group is an electrophile, such as an aldehyde, the coupling reaction conditions may comprise reductive amination reaction conditions. Ulus, tire conversion may comprise more than one reaction or set of reactants.
[0173] Upon reaction completion, compounds of Formula I can be recovered by conventional techniques such as neutralization, extraction, precipitation, chromatography, filtration and the like. In certain embodiments, when control of stereochemistry is desired, proper control of reaction conditions and selection of substituents for the reagents can at least partially dictate or preserve the formation of the various stereoisomers.
[0174] In some embodiments, the various substituents of compound 1-A or 1-B are as defined herein. However, derivatization thereof prior to reacting in any step, and / or further derivatization of the resulting reaction product, provides various compounds of Formula I. Appropriate starting materials and reagents can be purchased or prepared by methods known to one of skill in the art. Upon each reaction completion, each of the intermediate or final compounds can be recovered, and optionally purified, by conventional techniques such as neutralization, extraction, precipitation, chromatography, filtration, and the like. Other modifications to arrive at compounds of this disclosure are within the skill of the art.General Synthesis

Flow rate: 50 mL / min, Column temp.: 25 °C.Biological AssaysAnimals and diet
[0273] C57BL / 6J male mice were purchased from SMOC. Mice were group housed and fed a high-fat, high-sugar diet. Mice were maintained on this diet for 25-26 weeks prior to initializing the pharmacology studies. Mice were exposed to a controlled 12 h: 12 h light: dark cycle at ambient room temperature (22 °C) with ab libitum access to food and water. DIO mice were distributed into groups (n = 14 per group) such that statistical variations in the mean and standard deviations of fat mass and body weight were minimized between groups. The animals were grouped to receive treatment as follows: vehicle, tirzepatide. Compound B, Compound C-l, Compound B + tirzepatide, and Compound C-l + tirzepatide. Tirzepatide was administered by daily subQ dosing. Compound B and Compound C-l were administered by daily oral gavage.Body weight and food intake
[0274] Body weight (BW) and food intake were measured 3 times per week. The percent change in body was calculated individually for each mouse based on initial body weight prior to the first injection.Results
[0275] Fig. 1. Fig, 2, Fig. 3. and Fig. 4 show the efficacy of Compound B, Compound B + tirzepatide (TZP), azelaprag (AMG-986). azelaprag (AMG-986) + tirzepatide (TZP). and tirzepatide alone. Compound B + tirzepatide (TZP) led to additional weight loss and fat content decrease as compared to tirzepatide alone.
[0276] Compound B is G-protein biased APJ agonist with limited efficacy on receptor internalization. While azelaprag (AMG-986) is a non-biased APJ agonist with similar potency on both receptor internalization and cAMP pathway.
[0277] Both Compound B and Bioage molecule azelaprag (AMG-986) could amplify Tirzepatide efficacy on body weight loss in DIO model.
[0278] For in-vivo efficacy, Compound B required lower drug exposure than azelaprag (AMG-986). This is not consistent with in-vitro cAMP potency. Compound B demonstrated similar or better than bioage molecule azelaprag (AMG-986). Compound B required lower in-vivo drug exposure for efficacy, though azelaprag (AMG-986) is much more potent than Compound B in in-vitro cAMP assay.
[0279] Assay description: APJ-cAMP agonist assay, APJ-arrestin assay and APJ active internalization assay arc all performed in Eurofins Discovery X.
[0280] The ECso of Compound A and Compound B in APJ-cAMP assay was determined using DiscoverX Hunter® cAMP assays. Apelin / APJ mediates Gi signaling pathway. Therefore, for the agonism assay fonnat. ECso Forskolin is used to induce the cAMP response. The procedure was performed as follows: media was aspirated from cells and replaced with 10 uM HBSS / 10 mM HEPES. Then the compound was added to the cells, together witlr Forsolin, and incubated at 37°C for 30 minutes. cAMP signal is determined using DiscoverX Hunter® cAMP method.
[0281] The efficacy of the test compounds on arrestin recruitment was monitored by DiscoverX PathHunter® |3-Arrestin assay, and the efficacy of the test compounds on active internalization of APJ receptor with PathHunter® Activated GPCR. Internalization assays that could quantitative measurement of arrestin-mediated GPCR internalization.
[0282] Compound A has been shown to suppress cAMP production through activation of a G-protein- mediated signaling without significant activation of the B-arrestin pathway in order to avoid APJ internalization, and thereby potentially avoid any desensitization effects of an unbiased APJR agonist. As shown below, apelin peptide and clinically tested and clinically tested competitor compounds including azelaprag (AMG-986) and BMS-986224 are all non-biased APJR agonists in these invitro studies, with low B-arrestin / cAMP and intemalization / cAMP ratios. In contrast, Compound A and Compound B exhibit APJR biased agonism with much higher B-arrestin / cAMP and intemalization / cAMP ratios than apelin peptide and the test compounds shown below.Camp Assays
[0283] Activation of GLP-1 receptor is known to stimulate cyclic AMP (cAMP) production in cells which indicates primary coupling to the G as subunit of the G protein heterotrimeric complex. Evidence suggests signaling through G as induced cAMP stimulation elicits the desired pharmacological response regarding insulin release from pancreatic 0-cells.
[0284] To optimize functional activity directed toward G as coupling, a HEK293 / CRE-Luc cell line developed by HDB stably expressing the GLP-1 Receptor was used. 200* concentration of compound working solutions were prepared (Agilent Technologies Bravo) with 1 / 2 log serial dilution in 384-well Echo LDV plate (Labcyte, Cat#LP-0200). 50 nL / well 200x concentration of compound working solutions were moved to 384-well white low volume plate (Greiner, Cat#784075) using Labcyte ECHO550. 1 x 10 5 cells / mL HEK293 / GLP1R / CRE-LUC (HD Biosciences) cell suspensions prepared with assay buffer (DPBS containing 0.5 mM IBMX (Sigma, Cat#I5879) and 0.1% BSA (GENVIEW, Cat#FA016-100g)), 10 uL cell suspensions were added to each well of previous generated assay plate which already contains 50 nL compound at 200 x concentration using ThermoFisher Multidrop Combi (1000 cells / well). Seal the plate and incubate at 37 °C with 5% CCL for 30 min.
[0285] After incubation the cAMP assay signal was generated using cAMP dynamic 2 Kit (Cisbio). 5pL cAMP-d2 working solution was added to each well, followed with 5pL Anti -cAMP antibody - cryptate working solution added to each well using ThermoFisher Multidrop Combi. Incubate at room temperature for 1 hour protected from light. Read the fluorescence at 665 and 615 nm with Reader PerkinElmer EnVision.%Activity = 100% x (mean RLU of test sample -mean RLU of vehicle control) / (mean RLU of MAX control -mean RLU of vehicle control)
