The present disclosure provides compounds for modulating calcitonin receptor and/or amylin receptor activity, as well as pharmaceutical compositions comprising the compounds disclosed herein. Also provided are methods for treating calcitonin receptor and/or amylin receptor associated diseases, disorders, and conditions.
Calcitonin and amylin are hormones that interact with receptors within the same family to exert their effects on the human organism. Calcitonin, derived from thyroid C cells, is known for its inhibitory effect on osteoclasts. Calcitonin of mammalian origin promotes insulin sensitivity, while the more potent calcitonin extracted from salmon additionally inhibits gastric emptying, promotes gallbladder relaxation, increases energy expenditure and induces satiety as well as weight loss. Studies have also indicated that oral salmon calcitonin (sCT) exerts an insulin-sensitizing effect to improve glucose metabolism in obesity and type 2 diabetes. European Journal of Pharmacology, 2024, 737(7): 91-96.
Amylin receptors (AMYRs) are G protein-coupled receptors (GPCRs), which respond to the peptide hormones amylin and calcitonin. Amylin receptors are heterodimers comprising the calcitonin receptor, which is a G protein-coupled receptor, and one of three receptor-modifying proteins. Amylin, formed primarily in pancreatic islet β cells, is cosecreted with insulin in response to caloric intake. Patients with type 1 diabetes have lower baseline amylin serum concentrations, and amylin response to caloric intake is absent. Patients with type 2 diabetes requiring insulin also have a diminished amylin response to caloric intake, potentially related to the degree of β-cell impairment. Key physiologic functions of amylin in maintaining glucose homeostasis include suppressing glucagon release in response to caloric intake, delaying the rate of gastric emptying, and stimulating the satiety center in the brain to limit caloric intake.
The synthetic amylin analogue pramlintide is an approved treatment for diabetes mellitus as an adjunctive therapy to mealtime insulin which promotes better glycemic control and small but significant weight loss. AM833 (cagrilintide), an investigational novel long-acting acylated amylin analogue, acts as a non-selective amylin receptor agonist. This amylin receptor agonist can serve as an attractive novel treatment for obesity, resulting in reduction of food intake and significant weight loss in a dose-dependent manner. J Obes Metab Syndr. 2021; 30(4): 320-325.
Accordingly, modulators of the amylin and/or calcitonin receptor could be useful in treating various metabolic disorders, as well as inducing weight loss.
The present disclosure provides small molecule calcitonin and/or amylin receptor modulators (e.g., amylin-receptor agonists), as well as pharmaceutical compositions comprising the compounds disclosed herein. Also provided are methods for treating calcitonin receptor and/or amylin receptor associated diseases or disorders. It has been shown that calcitonin receptor activation is important for blood glucose regulation in diabetes; this is in addition to the known metabolic beneficial role of amylin receptor activation. Journal of Pharmacology and Experimental Therapeutics, 2020, 374 (1) 74-83.

As used herein, the term “compound,” is meant to include any or all stereoisomers, geometric isomers, tautomers, and isotopically enriched analogs (e.g., deuterated analogs) of the structures depicted. Compounds herein identified by name or structure as one particular tautomeric form are intended to include other tautomeric forms unless otherwise specified.
Some of the compounds exist as tautomers. Tautomers are in equilibrium with one another. For example, amide containing compounds may exist in equilibrium with imidic acid tautomers. Regardless of which tautomer is shown, and regardless of the nature of the equilibrium among tautomers, the compounds are understood by one of ordinary skill in the art to comprise both amide and imidic acid tautomers. 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.
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, except that 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 as 2H, 3H, 11C, 13C, 14C, 13N, 15N, 15O, 17O, 18O, 31P, 32P, 35S, 18F, 36Cl, 123I, and 125I, respectively. Various isotopically labeled compounds of the present disclosure, for example those into which radioactive isotopes such as 3H and 14C 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.
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.
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. An 18F, 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.
The 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 many cases, the compounds of this disclosure are capable of forming acid and/or base salts by virtue of the presence of amino and/or carboxyl groups or groups similar thereto.
Provided are also pharmaceutically acceptable salts, hydrates, solvates, tautomeric forms, polymorphs, and prodrugs of the compounds described herein. “Pharmaceutically acceptable” or “physiologically acceptable” refer to compounds, salts, compositions, dosage forms and other materials which are useful in preparing a pharmaceutical composition that is suitable for veterinary or human pharmaceutical use.
The term “pharmaceutically acceptable salt” of a given compound refers to salts that retain the biological effectiveness and properties of the given compound and which are not biologically or otherwise undesirable. “Pharmaceutically acceptable salts” or “physiologically acceptable salts” include, for example, salts with inorganic acids and salts with an organic acid. 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. Salts derived from organic acids include, e.g., acetic acid, propionic acid, gluconic acid, glycolic acid, pyruvic acid, oxalic acid, malic acid, malonic acid, succinic acid, maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluene-sulfonic acid, salicylic acid, and the like. Likewise, pharmaceutically acceptable base addition salts can be prepared from inorganic and organic bases. Salts derived from inorganic bases include, by way of example only, sodium, potassium, lithium, aluminum, ammonium, calcium, and magnesium salts. Salts derived from organic bases include, but are not limited to, salts of NH3, or primary, secondary, tertiary amines, such as salts derived from a N-containing heterocycle, a N-containing heteroaryl, or derived from an amine of formula N(RN)3 (e.g., HN+(RN)3 or (alkyl)N+(RN)3) where each RN is independently hydrogen, alkyl, alkenyl, alkynyl, haloalkyl, cycloalkyl, heterocyclyl, aryl, or heteroaryl, wherein each is optionally substituted, such as by one or more (e.g., 1-5 or 1-3) substituents (e.g., halo, cyano, hydroxy, amino, alkyl, alkenyl, alkynyl, haloalkyl, alkoxy, or haloalkoxy). Specific examples of suitable amines include, by way of example only, isopropylamine, trimethyl amine, diethyl amine, tri(iso-propyl) amine, tri(n-propyl) amine, ethanolamine, 2-dimethylaminoethanol, piperazine, piperidine, morpholine, N-ethylpiperidine, and the like.
The term “substituted” means that any one or more hydrogen atoms on the designated atom or group is replaced with one or more substituents other than hydrogen, provided that the designated atom's normal valence is not exceeded. The one or more substituents include, but are not limited to, acyl, alkenyl, alkoxy, alkoxyalkyl, alkyl, alkylthio, alkynyl, amidino, amido, amino, aryl, azido, carbamoyl, carboxyl, carboxyl ester, cyano, cyanoalkyl, cycloalkyl, cycloalkylalkyl, guanidino, halo, haloalkoxy, haloalkoxyalkyl, haloalkyl, heteroalkyl, heteroaryl, heterocyclyl, hydrazino, hydroxy, hydroxyalkyl, imido, imino, nitro, oxo, sulfinyl, sulfonic acid, sulfonyl, thiocyanate, thiol, thione, or combinations thereof.
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 hydroxy, halo, alkoxy, cycloalkyl, heterocyclyl, aryl, and heteroaryl. In other embodiments, the one or more substituents may be further substituted with halo, alkyl, haloalkyl, hydroxy, alkoxy, cycloalkyl, heterocyclyl, aryl, or heteroaryl, each of which is substituted. In other embodiments, the substituents may be further substituted with halo, alkyl, haloalkyl, alkoxy, hydroxy, cycloalkyl, heterocyclyl, aryl, or heteroaryl, each of which is unsubstituted.
As used herein, “pharmaceutically acceptable carrier” or “pharmaceutically acceptable excipient” includes any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents and the like. The use of such media and agents for pharmaceutically active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active ingredient, its use in the therapeutic compositions is contemplated.

The terms “effective amount” or “effective dosage” or “pharmaceutically effective amount” or “therapeutically effective amount,” as used herein, refer to a sufficient amount of a chemical entity (e.g., a compound of Formula I, or a pharmaceutically acceptable salt, stereoisomer, mixture of stereoisomers, or solvate thereof) being administered which will relieve to some extent one or more of the symptoms of the disease or condition being treated, and can include curing the disease. “Curing” means that the symptoms of active disease are eliminated. The result includes reduction and/or alleviation of the signs, symptoms, or causes of a disease, or any other desired alteration of a biological system. For example, an “effective amount” for therapeutic uses is the amount of the composition comprising a compound as disclosed herein required to provide a clinically significant decrease in disease symptoms. An appropriate “effective” amount in any individual case is determined using any suitable technique, such as a dose escalation study. In some embodiments, a “therapeutically effective amount” of a compound as provided herein refers to an amount of the compound that is effective as a monotherapy or combination therapy.
The term “excipient” or “pharmaceutically acceptable excipient” means a pharmaceutically-acceptable material, composition, or vehicle, such as a liquid or solid filler, diluent, carrier, solvent, or encapsulating material. In some embodiments, each component is “pharmaceutically acceptable” in the sense of being compatible with the other ingredients of a pharmaceutical formulation, and suitable for use in contact with the tissue or organ of humans and animals without excessive toxicity, irritation, allergic response, immunogenicity, or other problems or complications, commensurate with a reasonable benefit/risk ratio.

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 determined by one skilled in the art by routine optimization procedures.
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.
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.
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 Supplementals (Elsevier Science Publishers, 1989), Organic Reactions, Volumes 1-40 (John Wiley, and Sons, 1991), March's Advanced Organic Chemistry, (John Wiley, and Sons, 5th Edition, 2001), and Larock's Comprehensive Organic Transformations (VCH Publishers Inc., 1989).
Scheme I illustrates a general method which can be employed for the synthesis of compounds described herein, where each wherein each of A, Ring B, L1, L2, Y1, Y2, Y3, R4, and R5, are independently as defined herein, and R50 is an alkyl or substituted alkyl.
A Hantzsch style pyridine synthesis strategy can be used to synthesize the multi-substituted pyridine-based compound I-4 or compound I-7. As shown in Scheme I, coupling compound I-1 with compounds I-2 and I-3 provides I-4, and coupling compound I-6 with compounds I-2 and I-3 provides I-7. In some embodiments, the coupling reaction is performed under heated conditions in a suitable solvent (e.g., ethanol). Oxidation of 1-4, such as by CAN or DDQ, provides compound I-5, which can then be further transformed into a heteroaryl using methods known in the art to provide compounds of Formula I. Oxidation of compound I-7 under similar reaction conditions provides compounds of Formula I.
For any compound shown in Scheme I, it should be understood that various derivatives can be provided by functional group interconversion at any step. In some embodiments, the various substituents of compounds I-1, I-2, I-3, I-4, I-5, I-6, or I-7 (e.g., A, Ring B, L1, L2, Y1, Y2, Y3, R4, and R) are as defined herein. However, derivatization of compounds I-1, I-2, I-3, I-4, I-5, I-6, or I-7 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 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. Compounds I-1, I-2, and I-3 may be commercially obtained or synthesized de novo. For example, compound I-1 and compound I-6 may be prepared as shown in Scheme II or III.
Compound A-1 reacts with Meldrum's acid to give intermediate A-2, which undergoes decarboxylation to give β-ketoacid compound I-1. Compound I-1 can be also directly synthesized by reacting A-1 with an alkyl potassium malonate in presence of CDI and MgCl2.
Compound I-1 can could also react with ethane-1,2-diol to give intermediate A-3. Generally, the carboxylate group of A-3 can be transformed to various heteroaryl groups to give intermediate A-7, which undergoes deprotection by mixture of H2SO4 and formic acid to give compound I-6. For example, hydrolysis of the ester group of intermediate A-3 gives rise to a carboxylic acid, which can be reacted under conditions suitable to provide intermediate A-7 (e.g., reaction with acetohydrazide with the help of HATU and DIEA, which undergoes cyclization using 4-toluenesulfonyl chloride to give an oxadiazole). Deprotection of intermediate A-7 provides compound I-6.
Carboxylic acid A-1 reacts with carboxylic acid potassium salt A-8 in presence of CDI and MgCl2 gives compound I-6.
The following Scheme IV demonstrates a general scheme for the synthesis of indanyl amine I-7, which can be used to prepare compounds of Formula I where R5 is optionally substituted cycloalkyl.
Aldehyde A-8 (where v is 0-5 and each Z5 is independently as defined herein) reacts with Meldrum's acid A-9 to give carboxylic acid A-10. It was reacted with oxalyl chloride to give its corresponding acyl chloride A-11 which undergoes an intra-molecular Friedel-Crafts acylation generating ketone A-12. It was then reacted with A-13 to give tert-butylsulfinamide A-14. Reduction of the sulfinamide using DIBAL-H gives A-15. Deprotection under acidic condition give rise to the indanyl amine intermediate I-7.
Upon each reaction completion, each of the intermediates 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.
Typical embodiments of compounds described herein may be synthesized using the general reaction schemes described below. It will be apparent given the description herein that the general schemes may be altered by substitution of the starting materials with other materials having similar structures to result in products that are correspondingly different. Descriptions of syntheses follow to provide numerous examples of how the starting materials may vary to provide corresponding products. Given a desired product for which the substituent groups are defined, the necessary starting materials generally may be determined by inspection.

Amylin Receptor cAMP Assay I
AMYRs are heterodimers of the class B calcitonin (CT) G-protein-coupled receptor (CTR) and receptor activity-modifying proteins (RAMPs). All three RAMPs can interact with the CTR and form AMY1, AMY2, AMY3 with RAMP1, RAMP2 and RAMP3, respectively. Like other class B1 GPCRs, the CT receptor family is canonically coupled to Gs-mediated cAMP production, and measurement of cAMP accumulation has been the primary assay used to determine peptide selectivity and potency.
To optimize functional activity directed toward Gas coupling, COS-7 cells were stably transfected with human calcitonin receptor (CTR) and RAMP3, simultaneously. 100×concentration of compound working solutions were prepared (Agilent Technologies Bravo) with 4-fold serial dilution in 384-well Echo LDV plate (Labcyte, Cat #LP-0200). 100 nL/well 100× concentration of compound working solutions were moved to 384-well white low volume plate (Greiner, Cat #784075) using Labcyte ECHO550. 1×105 cells/mL COS-7/CTR or COS-7/AMY3 (HD Biosciences) cell suspensions prepared with assay buffer [DPBS containing 0.5 mM IBMX (Sigma, Cat #15879) and 0.1% BSA (GENVIEW, Cat #FAO16-100 g)], 10 μL cell suspensions were added to each well of previous generated assay plate which already contains 100 nL compound at 100× concentration using ThermoFisher Multidrop Combi (1000 cells/well). Seal the plate and incubate at 37° C. with 5% CO2 for 30 min.
After incubation, the cAMP assay signal was generated using cAMP Hi-range Kit (Cisbio). 5 μL cAMP-d2 working solution was added to each well, followed by 5 μL Anti-cAMP antibody-cryptate working solution which was added to each well using ThermoFisher Multidrop Combi. The samples were then incubated at room temperature for 1 hour protected from light. the fluorescence was read at 665 and 615 nm with Reader PerkinElmer EnVision.

Calcitonin receptor (CTR) cAMPAssay
The calcitonin receptor (CTR) belongs to the subfamily of GPCRs known as the secretin or ‘B’ family of GPCRs. Like other class B1 GPCRs, the CT receptor family is canonically coupled to Gs-mediated cAMP production, and measurement of cAMP accumulation has been the primary assay used to determine peptide selectivity and potency.
To optimize functional activity directed toward Gas coupling, COS-7 cells were stably transfected with human calcitonin receptor (CTR) to create COS7-human CTR Clone #2 stable cell line. 100× concentration of compound working solutions were prepared with 4-fold serial dilution in 384-well Echo LDV plate (Labcyte, Cat #LP-0200-BC). 200 nL/well 100×concentration of compound working solutions were moved to 384-well white microplate (Perkin Elmer, Cat #6007680) using Labcyte ECHO550. 1×10′ cells/mL COS7-human CTR Clone #2 cell suspensions prepared with assay buffer [HBSS containing 20 mM HEPES (Gibco, Cat #15630-080), 0.5 mM IBMX (Sigma, Cat #15879) and 0.1% Casein (Sigma, Cat #C4765)], 20 μL cell suspensions were added to each well of previous generated assay plate which already contains 200 nL compound at 100×concentration using ThermoFisher Multidrop Combi (2000 cells/well).

The binding potency of a ligand to a protein receptor can be determined using Free Energy Perturbation (FEP), a physics-based free energy perturbation technology for computationally predicting protein-ligand binding potency (Schrödinger Inc., see, e.g.,1,2 as depicted in
The results provided in the Table and Figures were generated using FEP+ with the OPLS4 force field in Life Science Schrödinger Suite Release 2023,13 using sampling timescale of 15 ns. Relative FEP calculations are run with reference to congeneric ligands with previously measured experimental in vitro potency against the human calcitonin receptor or human amylin receptor. The binding mode of the congeneric ligands are defined on the basis of a resolved ligand protein complex structure, here a cryogenic electron microscopy (cryo-EM) structure, and the whole system can be described in full atomistic detail to include ligand, protein, lipid bilayer and water molecule(s).
The mean unsigned error between the FEP+ with OPLS4 values and the human calcitonin receptor agonist cAMP experimental measurements was calculated to be 0.8 log units (˜1.1 kcal/mol), which is in line with the average performance across drug discovery projects, as referenced in 2 The mean unsigned error between the FEP predicted values and the human amylin receptor agonist cAMP experimental measurements was calculated to be 0.6 log units.
