The disclosure is directed to compounds that modulate the glucagon-like peptide 1 (GLP-1) receptor, as well as to related products and methods for their use and synthesis. BACKGROUND

Glucagon-like peptide 1 receptor (GLP-1R) belongs to Family B1 of the seven-transmembrane G protein-coupled receptors, and its natural agonist ligand is the peptide hormone glucagon-like peptide-1 (GLP-1). GLP-1 is a peptide hormone arising by its alternative enzymatic cleavage from proglucagon, the prohormone precursor for GLP-1, which is highly expressed in enteroendocrine cells of the intestine, the alpha cells of the endocrine pancreas (islets of Langerhans), and the brain (Kieffer T. J. and Habener, J. F. Endocrin. Rev. 20:876-913 (1999); Drucker, D. J., Endocrinology 142:521-7 (2001); Holst, J. J., Diabetes Metab. Res. Rev.18:430-41 (2002)). The initial actions of GLP-1 observed were on the insulin-producing cells of the islets, where it stimulates glucose-dependent insulin secretion. Subsequently, multiple additional antidiabetogenic actions of GLP-1 were discovered including the stimulation of the growth and inhibition of the apoptosis of pancreatic beta cells (Drucker, D. J., Endocrinology 144:5145-8 (2003); Holz, G. G. and Chepurny O. G., Curr. Med. Chem. 10:2471-83 (2003); List, J. F. and Habener, J. F., Am. J. Physiol. Endocrinol. Metab. 286:E875-81 (2004)).

On activation, GLP-1 receptors couple to the α subunit of G protein, with subsequent activation of adenylate cyclase and increase of cAMP levels, thereby potentiating glucose-stimulated insulin secretion. Therefore, GLP-1 is an attractive target to lower blood glucose levels and preserve the β-cells of the pancreas of diabetic patients. Glucagon has been used for decades in medical practice within diabetes and several glucagon-like peptides are being developed for various therapeutic indications. GLP-1 analogs and derivatives are being developed for the treatment for patients suffering from diabetes. While advances have been made in this field, there remains a significant need for modulators of the GLP-1 receptor, particularly GLP-1 receptor agonists, as well as for products and methods related to the same. The present disclosure fulfills these and other needs, as described in more detail in the following detailed description. SUMMARY OF INVENTION

By "spirocyclic" is meant the class of structures wherein two rings are fused at a single tetrahedral carbon atom, as is well known in the art.

When two“R” groups are said to be joined together or taken together to form a ring, it is meant that together with the carbon atom or a non-carbon atom (e.g., nitrogen atom), to which they are bonded, they may form a ring system. In general, they are bonded to one another to form a 3- to 7-membered ring, or a 5- to 7-membered ring. Non-limiting specific examples are the cyclopentyl, cyclohexyl, cycloheptyl, piperidinyl, piperazinyl, pyrolidinyl, pyrrolyl, pyridinyl.

In the special case wherein the carbonyl carbon atom is bonded to a hydrogen, the group is a“formyl” group, an acyl group as the term is defined herein. An acyl group can include 0 to about 12-20 additional carbon atoms bonded to the carbonyl group. An acyl group can include double or triple bonds within the meaning herein. An acryloyl group is an example of an acyl group. An acyl group can also include heteroatoms within the meaning here. A nicotinoyl group (pyridyl-3-carbonyl) group is an example of an acyl group within the meaning herein. Other examples include acetyl, benzoyl, phenylacetyl, pyridylacetyl, cinnamoyl, and acryloyl groups and the like.

An "ammonium" ion includes the unsubstituted ammonium ion NH ⁺

4 , but unless otherwise specified, it also includes any protonated or quaternarized forms of amines. Thus, trimethylammonium hydrochloride and tetramethylammonium chloride are both ammonium ions, and amines, within the meaning herein. The term "amide" or "amido" includes C- and N-amide groups, i.e., -C(O)NR ₂ , and–NRC(O)R groups, respectively. Amide groups therefore include but are not limited to carbamoyl groups (-C(O)NH ₂ ) and formamide groups (- NHC(O)H). A "carboxamido" group is a group of the formula C(O)NR ₂ , wherein R can be H, alkyl, aryl, etc.

The term "carbonyl," refers to a -C(O)- group.

In one embodiment, a compound is provided having the structure any one of compound numbers 1-153 as shown in the following Table 1, or a stereoisomer, hydrate, solvate, isotope or pharmaceutically acceptable salts thereof.

Table 1

Representative Compounds

Compound Nos. 1-153 of Table 1 above include, but are not limited to, hydrates, hydrates and/or isotopes thereof, as well as pharmaceutically acceptable salts thereof.

A "salt" as is well known in the art includes an organic compound such as a carboxylic acid, a sulfonic acid, or an amine, in ionic form, in combination with a counter ion. For example, acids in their anionic form can form salts with cations such as metal cations, for example sodium, potassium, and the like; with ammonium salts such as NH ⁺

4 or the cations of various amines, including tetraalkyl ammonium salts such as tetramethylammonium, or other cations such as trimethylsulfonium, and the like.

A "pharmaceutically acceptable salt" is a salt formed from a counter ion that has been approved for human consumption and is generally non-toxic.

Acid addition salts of the disclosed compounds include, for example, salts prepared by adding and inorganic acid or an organic acid. Examples of inorganic acids include, but are not limited to, hydrochloric, hydrobromic, hydriodic, nitric, carbonic, sulfuric, and phosphoric acids. Appropriate organic acids include, but are not limited to, aliphatic, cycloaliphatic, aromatic, araliphatic, heterocyclic, carboxylic and sulfonic classes of organic acids, representative examples of which include formic acetic, propionic, succinic, glycolic, gluconic, lactic, malic, tartaric, citric, ascorbic, glucuronic, maleic, fumaric, pyruvic, aspartic, glutamic, benzoic, anthranilic, 4- hydroxybenzoic, phenylacetic, mandelic, embonic (pamoic), methanesulfonic, ethanesulfonic, benzenesulfonic, panthothenic, trifluoromethanesulfonic, 2- hydroxyethanesulfonic, p-toluenesulfonic, sulfanilic, cyclohexylaminosulfonic, stearic, alginic, β-hydroxybutyric, salicylic, galactaric and galacturonic acid.

Base addition salts of the disclosed compounds include, but are not limited to, salts prepared by adding alkali metal, alkaline earth metal and transition metal salts such as, for example, calcium, magnesium, potassium, sodium and zinc salts. Representative base addition salts also include salts made from organic bases such as, for example, N,N'-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumine (N-methylglucamine) and procaine.

A "hydrate" is a compound that exists in a composition with water molecules. The composition can include water in stoichiometric quantities, such as a monohydrate or a dihydrate, or can include water in random amounts. As the term is used herein a "hydrate" refers to a solid form (i.e., a compound in water solution, while it may be hydrated, is not a hydrate as the term is used herein).

A "solvate" is a similar composition except that a solvent other that water replaces the water. For example, methanol or ethanol can form an "alcoholate", which can again be stoichiometric or non-stoichiometric. As the term is used herein a "solvate" refers to a solid form (i.e., a compound in solution in a solvent, while it may be solvated, is not a solvate as the term is used herein).

The term“isotope” refers to atoms with the same number of protons but a different number of neutrons, and an isotope of a compound of Formula (I) includes any such compound wherein one or more atoms are replaced by an isotope of that atom. For example, carbon 12, the most common form of carbon, has six protons and six neutrons, whereas carbon 13 has six protons and seven neutrons, and carbon 14 has six protons and eight neutrons. Hydrogen has two stable isotopes, deuterium (one proton and one neutron) and tritium (one proton and two neutrons). While fluorine has a number of isotopes, fluorine 19 is longest-lived. Thus, an isotope of a compound having the structure of Formula (I) includes, but not limited to, compounds of Formula (I) wherein one or more carbon 12 atoms are replaced by carbon 13 and/or 14 atoms, wherein one or more hydrogen atoms are replaced with deuterium and/or tritium, and/or wherein one or more fluorine atoms are replaced by fluorine 19.

“Stereoisomers” include all chiral, enantiomeric, diastereomeric and/or racemic forms of a compound, unless a particular stereochemistry or isomeric form is specifically indicated. Compounds of the present invention include enriched or resolved optical isomers at any or all asymmetric atoms as are apparent from the depictions, at any degree of enrichment, including, for example, enrichment to a weight purity of 98%, 99%, 99.5% or 99.9%. Both racemic, enantiomeric and diastereomeric mixtures, as well as the individual optical isomers, can be synthesized so as to be substantially free of their enantiomeric or diastereomeric partners, and these are all within the scope of certain embodiments of the invention.

Enantiomers are sometimes called optical isomers because a pure enantiomer rotates plane-polarized light in a particular direction. If the light rotates clockwise, then that enantiomer is labeled“(+)” or“d” for dextrorotatory, its counterpart will rotate the light counterclockwise and is labeled“(-)” or“l” for levorotatory. Stereoisomers that differ at some stereocenters but not at others are not mirror images, so they are not enantiomers. Instead, they are referred to as diastereomers. A diastereomer is any stereoisomer that is not an enantiomer.

The terms "racemate" and "racemic mixture" are frequently used interchangeably. A racemate is an equal mixture of two enantiomers. A racemate is labeled“(±)” because it is not optically active (i.e., will not rotate plane-polarized light in either direction since its constituent enantiomers cancel each other out).

In certain representative embodiments, the“A” group of Formula (I) has the following structure, wherein the asterisk (*) denotes chiral carbon.

While the above disclosure depicts stereo confirmation at a single chiral center, it should be understood that the presence of multiple chiral centers allows for multiple combinations of stereoisomers (e.g., two chiral centers will give four possible orientations, and so forth). It is intended that compounds having the structure of any one of Formulas (I)-(XII) above include all stereoisomers arising from the presence of one or more chiral centers, including any and all enantiomeric and/or diastereomeric forms, at any degree of purity, as well as racemic mixtures of the same.

In a further representative embodiment, R ² is cyclohexyl substituted with R ³ , as illustrated below. In this embodiment, the noted hydrogen atoms can exist in a cis- or trans-confi uration:

Accordingly, it is intended that compounds having the structure of any one of Formulas (I)-(XII) above also include stereoisomers involving geometric isomersism, such as the cis- and/or trans-isomers illustrated above. It should also be understood that a prodrug is a substance that can be administered to a patient where the substance is converted in vivo by the action of biochemicals within the patient’s body, such as enzymes, to the active pharmaceutical ingredient. Examples of prodrugs include esters of carboxylic acid groups, which can be hydrolyzed by endogenous esterases as are found in the bloodstream of humans and other mammals. In one embodiment of the present invention, substances are provided that can be administered to a patient where the substance is converted in vivo by the action of biochemical reactions within the patient's body, such as enzymes, to a compound having the structure of any one of Formulas (I)-(XII), or a compound of Table 1.

In one embodiment, a pharmaceutical composition is provided comprising a compound of Formula (I)-(XII), a compound of Table 1, or a pharmaceutically acceptable salt thereof, in combination with at least one pharmaceutically acceptable carrier, diluent or excipient.

As use herein, a compound that“modulates” a GLP-1 receptor means that the compound interacts with the receptor, either directly or by way of an allosteric interaction, thereby activating, potentiating and/or agonizing the GLP-1 receptor for which it modulates.

In one embodiment, the present invention encompasses compounds that modulate GLP-1 receptor, with high affinity and specificity, an agonist manner or as an activator or a potentiator. In another embodiment, a compound of the invention acts as a positive allosteric modulator of GLP-1 receptor.

In one embodiment, the present invention provides a method for agonizing a GLP-1 receptor with a compound of the invention (i.e., an agonist). The method involves contacting the receptor with a suitable concentration of an inventive compound to bring about activation of the receptor. The contacting can take place in vitro, for example in carrying out an assay to determine the GLP-1 receptor activation activity of an inventive compound undergoing experimentation related to a submission for regulatory approval.

In one embodiment, the method for modulating a GLP-1 receptor, can also be carried out in vivo, that is, within the living body of a mammal, such as a human patient or a test animal. The inventive compound can be supplied to the living organism via one of the routes as described above (e.g., orally), or can be provided locally within the body tissues. In the presence of the inventive compound, activation of the receptor takes place and the effect thereof can be studied.

In one embodiment, a method is provided for modulation of a GLP-1 receptor by contacting the receptor with an effective amount of a compound of this invention, or a pharmaceutical composition comprising the same, wherein the GLP-1 receptor is disposed within a living mammal.

In one embodiment, a method is provided for treatment of a malcondition in a subject for which modulation of a GLP-1 receptor is medically indicated, by administering an effective amount of a compound of this invention to the subject at a frequency and for duration of time sufficient to provide a beneficial effect to the subject (e.g., patient).

“Treating” or "treatment" refers to an alleviation of symptoms associated with a disorder or disease, or inhibition of further progression or worsening of those symptoms, or prevention or prophylaxis of the disease or disorder.

“Effective amount” refers to an amount sufficient to produce a beneficial therapeutic effect on the patient. For example,“effective amount” or a“therapeutically effective amount” of a compound of the invention refers to an amount of the compound that alleviates, in whole or in part, symptoms associated with the disorder or condition, or halts or slows further progression or worsening of those symptoms, or prevents or provides prophylaxis for the disorder or condition. In particular, a "therapeutically effective amount" refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired therapeutic result by acting as a modulator of GLP-1 activity. A therapeutically effective amount is also one in which any toxic or detrimental effects of compounds of the invention are outweighed by the therapeutically beneficial effects. For example, in the context of treating a malcondition mediated by activation of a GLP-1 receptor, a therapeutically effective amount of a GLP-1 receptor agonist is an amount sufficient to control the malcondition, to mitigate the progress of the malcondition, or to relieve the symptoms of the malcondition. The dosages and formulations for the other agents to be employed, where applicable, will be as set out in the latest edition of the Physicians' Desk Reference, incorporated herein by reference.

In one embodiment, a method is provided for treatment of a malcondition in a subject for which modulation of a GLP-1 receptor is medically indicated, by administering an effective amount of a compound of this invention to the subject at a frequency and for a duration of time sufficient to provide a beneficial effect to the subject, wherein the malcondition comprises type I diabetes, type II diabetes, gestational diabetes, obesity, excessive appetite, insufficient satiety, or metabolic disorder. In one embodiment, the subject is a patient or a human being. In certain embodiments, the human being is afflicted with, or at risk of developing, a disease or condition selected from the group consisting of type I diabetes, type II diabetes, gestational diabetes, obesity, excessive appetite, insufficient satiety, and metabolic disorder. In one embodiment, said disease is type I diabetes or type II diabetes.

In another embodiment, methods of treatment provided by the invention include administration of a compound of the invention to a subject (e.g., patient) for the treatment of non-alcoholic fatty liver disease (NAFLD) and/or non-alcoholic steatohepatitis (NASH). NAFLD is believed to be caused by the disruption of hepatic lipid homeostasis and, at least in a portion of patients, can progress to NASH. NAFLD is associated with insulin resistance in type 2 diabetes mellitus, and GLP1 increases insulin sensitivity and aids glucose metabolism. The compounds of this invention are beneficial in this context by serving to increase fatty acid oxidation, decrease lipogenesis, and/or improve hepatic glucose metabolism (see e.g., Lee et. al., Diabetes Metab. J. 36:262-267, 2012; Trevaskis et al. Am. J. Physiol. Gastrointest. Liver Physiol. 302:G762-G772, 2012; Kim et al. Korean J. Physiol. Pharmacol. 18:333-339, 2014; and see: Armstrong et. al., Journal of Hepatology 62:S187-S212, 2015 for results with Liraglutide in Phase II trials).

In one embodiment, methods are provided for use of a compound of this invention for preparation of a medicament adapted for treatment of a disorder or a malcondition wherein modulation of a GLP-1 receptor is medically indicated.

In one embodiment, the invention provides methods for synthesis of certain compounds including compounds of the invention as more fully illustrated herein. In certain other embodiments, the invention provides certain intermediate compounds associated with such methods of synthesis as illustrated herein.

Fractions were collected by UV detection at 254 nm or by mass and evaporated using a Genevac EZ-2.

General Procedure 1. Palladium-Catalyzed Coupling Reactions.

A solution of boronic acid or boronate ester (1.0– 1.3 eq), halide (1.0– 1.3 eq), sodium bicarbonate or sodium carbonate decahydrate (2.0– 2.5 eq), and dichloro[1,1’-bis(di-tert-butylphosphino)ferrocene]palladi um(II) or Pd(dppf)Cl ₂ were combined in THF, acetonitrile, or dioxane (0.1– 0.2 M) and water (0.25– 0.50 M). The reaction was heated at 80 to 100ºC until complete. The reaction was diluted with EA and washed with saturated aqueous NaHCO ₃ . The organic layer was dried over MgSO ₄ and concentrated. The product can be purified by chromatography, preparative HPLC, or carried on to the next step without further purification.

General Procedure 2. Preparation of Amides via Peptide Coupling.

A solution of amine (1.0 eq) and base (DIEA, TEA or NMM) (0– 3.0 eq) in DCM or DMF (0.08– 0.10 M) was treated with the appropriate carboxylic acid (1.0– 1.5 eq). To this mixture was added the coupling reagent. The coupling reagent could be HATU (1.05– 2.5 eq) optionally with DMAP (0.01– 1 eq), EDC (1.5 eq) with HOBt (1.5 eq) or DMAP (0.01– 1 eq), DCC (1.1 eq) with HOBt (1.1 eq) or DCC (1.5 eq) with DMAP (2.0 eq). The reaction mixture was stirred until the reaction was complete. The reaction was diluted with EA and washed with saturated aqueous NaHCO ₃ . The organic layer was dried over MgSO ₄ and concentrated. The product was purified by chromatography or alternatively can be carried on to the next step without further purification.

General Procedure 3. Hydrolysis of Methyl or Ethyl Esters to Acids.

To a stirring solution of ester (1 eq) in THF or dioxane and water, was added NaOH or LiOH (1– 3 eq). The reaction mixture was stirred at up to 60 ^o C for up to 18 h. The reaction mixture was neutralized with AcOH or HCl and either diluted with water or concentrated. If the reaction mixture was diluted with water, then HCl was added to acidify the reaction mixture to a pH of approximately 2. The resulting precipitate was isolated by filtration to yield product which can be purified by chromatography, preparative HPLC, or used without purification. Alternatively, a solution of the ester (1 eq) in DCE was treated with trimethylstannanol (9 eq) at 80 ^o C for 24 to 72 h. The mixture was diluted with DCM and water and passed through a phase separator and the organics concentrated to afford product which can be purified by chromatography, preparative HPLC, or used without purification.
