The present disclosure relates to compounds that bind to and act as agonists or modulators of the glucagon-like peptide-1 receptor (GLP-1R) and act as agonists or modulators of GLP-1R. The disclosure further relates to the use of the compounds for the treatment and/or prevention of diseases and/or conditions by said compounds.
Glucagon-like peptide-1 (GLP-1) is a peptide hormone that is secreted from the enteroendocrine cells in the gut in response to a meal. GLP-1 is believed to play a role in regulation of post-prandial glycemia, via directly augmenting meal-induced insulin secretion from the pancreatic beta-cells, as well as in promoting satiety by delaying the transit of food through the gut. GLP-1 mediates intracellular signaling via the GLP-1 receptor (GLP-1R) which belongs to a family of G-protein coupled receptors that are present on the cell membrane and can result in accumulation of the secondary messenger cyclic adenosine monophosphate (cAMP) upon activation. Non-alcoholic steatohepatitis (NASH) can be associated with features of metabolic syndrome, including obesity, type 2 diabetes, insulin resistance and cardiovascular disease.
GLP-1R agonists are currently being investigated in connection with diabetes, obesity, and NASH. GLP-1R agonists include peptides, such as exenatide, liraglutide, and dulaglutide, that have been approved for the management of type 2 diabetes. Such peptides are predominantly administered by subcutaneous injection. Oral GLP-1 agonists are also under investigation for treatment of type 2 diabetes. Some GLP-1R agonists, such as liraglutide, dulaglutide, and exenatide, are resistant to rapid degradation by dipeptidyl peptidase 4, resulting in longer half-lives than endogenous GLP-1.
There remains a need for compounds, such as agonists of GLP-1R, with desirable therapeutic properties, metabolic properties, and/or easy administration in the treatment of metabolic diseases and related diseases, including but not limited to NASH, obesity, and Type 2 diabetes.
In one embodiment, the present disclosure provides a compound of Formula (I):
or a pharmaceutically acceptable salt thereof, wherein
each optionally substituted with one to three Zia groups, each independently C1-6 alkyl, C1-6 haloalkyl, C1-6 alkoxy, C1-6 haloalkoxy, halogen, —OH, or —CN;
In another embodiment, a pharmaceutical composition is provided comprising a therapeutically effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable excipient.
In some embodiments of the compound of Formula (I), or pharmaceutically acceptable salt thereof, having the structure of a compound in Table 2.
Also disclosed herein are the in vivo metabolic products of the compounds described herein, to the extent such products are novel and unobvious over the prior art. Such products may result for example from the oxidation, reduction, hydrolysis, amidation, esterification and the like of the administered compound, primarily due to enzymatic processes. Accordingly, included are novel and unobvious compounds produced by a process comprising contacting a compound with a mammal for a period of time sufficient to yield a metabolic product thereof. Such products typically are identified by preparing a radiolabeled (e.g. 14C or 3H) compound, administering it parenterally in a detectable dose (e.g. greater than about 0.5 mg/kg) to an animal such as rat, mouse, guinea pig, monkey, or to man, allowing sufficient time for metabolism to occur (typically about 30 seconds to 30 hours) and isolating its conversion products from the urine, blood or other biological samples. These products can be easily isolated since they are labeled (others are isolated by the use of antibodies capable of binding epitopes surviving in the metabolite). The metabolite structures are determined in conventional fashion, e.g. by MS or NMR analysis. In general, analysis of metabolites can be done in the same way as conventional drug metabolism studies well-known to those skilled in the art. The conversion products, so long as they are not otherwise found in vivo, can be useful in diagnostic assays for therapeutic dosing of the compounds even if they possess no GLP-1R activity of their own.
Recipes and methods for determining stability of compounds in surrogate gastrointestinal secretions are known. Compounds are defined herein as stable in the gastrointestinal tract where less than about 50 mole percent of the protected groups are deprotected in surrogate intestinal or gastric juice upon incubation for 1 hour at 37° C. Simply because the compounds are stable to the gastrointestinal tract does not mean that they cannot be hydrolyzed in vivo. The prodrugs typically will be stable in the digestive system but may be substantially hydrolyzed to the parental drug in the digestive lumen, liver, lung or other metabolic organ, or within cells in general. As used herein, a prodrug is understood to be a compound that is chemically designed to efficiently liberate the parent drug after overcoming biological barriers to oral delivery.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.

Also disclosed herein are the in vivo metabolic products of the compounds described herein, to the extent such products are novel and unobvious over the prior art. Such products may result for example from the oxidation, reduction, hydrolysis, amidation, esterification and the like of the administered compound, primarily due to enzymatic processes. Accordingly, included are novel and unobvious compounds produced by a process comprising contacting a compound with a mammal for a period of time sufficient to yield a metabolic product thereof. Such products typically are identified by preparing a radiolabeled (e.g. 14C or 3H) compound, administering it parenterally in a detectable dose (e.g. greater than about 0.5 mg/kg) to an animal such as rat, mouse, guinea pig, monkey, or to man, allowing sufficient time for metabolism to occur (typically about 30 seconds to 30 hours) and isolating its conversion products from the urine, blood or other biological samples. These products can be easily isolated since they are labeled (others are isolated by the use of antibodies capable of binding epitopes surviving in the metabolite). The metabolite structures are determined in conventional fashion, e.g. by MS or NMR analysis. In general, analysis of metabolites can be done in the same way as conventional drug metabolism studies well-known to those skilled in the art. The conversion products, so long as they are not otherwise found in vivo, can be useful in diagnostic assays for therapeutic dosing of the compounds even if they possess no GLP-1R activity of their own.
Recipes and methods for determining stability of compounds in surrogate gastrointestinal secretions are known. Compounds are defined herein as stable in the gastrointestinal tract where less than about 50 mole percent of the protected groups are deprotected in surrogate intestinal or gastric juice upon incubation for 1 hour at 37° C. Simply because the compounds are stable to the gastrointestinal tract does not mean that they cannot be hydrolyzed in vivo. The prodrugs typically will be stable in the digestive system but may be substantially hydrolyzed to the parental drug in the digestive lumen, liver, lung or other metabolic organ, or within cells in general. As used herein, a prodrug is understood to be a compound that is chemically designed to efficiently liberate the parent drug after overcoming biological barriers to oral delivery.
The compounds of the present disclosure can be prepared by any method known in the art. The following exemplary general methods illustrate routes that may be used to obtain a compound of the present disclosure.
Intermediate 1.3 may be assembled by reacting an amine with Intermediate 1.1, wherein X is a halogen, and R is an alkyl, alkylaryl, or aryl, in the presence of a suitable base (e.g. DIPEA, KOtBu, etc.) to give Intermediate 1.2. Intermediate 1.2 can be converted to Intermediate 1.3 using suitable reducing conditions (e.g. H2 and Pd/C, Fe and HCl, etc.).
Compounds of Formula (I) having the structure of a compound of Formula 2.9 can be assembled by first coupling Intermediate 2.1, wherein X21 and X22 is each a leaving group, e.g., a halogen such as Cl or Br, with a heteroatom containing Intermediate 2.2 (where Y═O, NH, or S) using either a suitable base (e.g., DIPEA, KOtBu, etc.) or through metal mediated cross-coupling using a suitable palladium catalyst to give Intermediate 2.3 (Scheme 2). Intermediate 2.4 (where M=Li, MgBr, MgCl, or MgI, purchased commercially or obtained through metalation of a corresponding halide) can be combined with Intermediate 2.3 using a suitable palladium catalyst to deliver Intermediate 2.5. Following conversion to the acid Intermediate 2.6 using standard conditions (e.g. LiOH, LiI and pyridine, etc.), the Intermediate 1.3 can be added using standard amide bond forming conditions (e.g. DIPEA with HATU, etc.) to give Intermediate 2.7, which can, in turn, be converted to the corresponding benzimidazole Intermediate 2.8 under the influence of an acid catalyst (e.g. HCl, AcOH, etc.) This intermediate can be converted to the compound of Formula (I) using standard ester hydrolysis conditions (e.g., LiOH, LiI and pyridine, etc.).
While the above Scheme 2 is illustrated using Intermediate 2.1 as a dihalopyridine, any dihalogenated A-ring starting material can be used to obtain the analogous compound of Formula (I).
In some embodiments, a compound of Formula (I) having the structure of a compound of Formula 2.9 can be assembled first by the combination of Intermediate 3.1 (wherein X31 is Cl, Br, or I) with Intermediate 1.3 (wherein R=alkyl, alkylaryl, or aryl) under standard amide bond forming conditions, e.g. DIPEA with HATU, etc. (Scheme 3). Treatment with a suitable acid catalyst (e.g. HCl, AcOH, etc.) can deliver Intermediate 3.3. Halogen metal exchange of —X31 to -M can be achieved using a suitable reagent (e.g. iPrMgBr, etc.) or transition metal coupling using a suitable palladium catalyst and metal source (e.g. B2Pin2, Bu6Sn2, etc.) to give Intermediate 2.8 which can be converted to the compound of Formula (I) using standard ester hydrolysis conditions (e.g. LiOH, LiI and pyridine, etc.).
In some embodiments, a compound of Formula 2.9 can be formed by first conversion of Intermediate 2.3 to the metallated variant Intermediate 4.1 using a suitable palladium catalyst and metal source, e.g. B2Pin2, Bu6Sn2, etc. (Scheme 4).

A compound of Formula (I) having the structure of a compound of Formula 2.9 can be assembled through first cross-coupling of an Intermediate 3.4 with Intermediate 2.1 using a suitable transition metal catalyst (e.g. palladium, etc.) (Scheme 8). This can then be coupled with a heteroatom containing Intermediate 2.2 (where Y═O, N or S) using either a suitable base (e.g. DIPEA, KOtBu, etc.) or through metal mediated cross-coupling using a suitable palladium catalyst to give Intermediate 2.8. Intermediate 2.8 can be converted to the compound of Formula (I) having the structure of a compound of Formula 2.9 using standard ester hydrolysis conditions (e.g. LiOH, LiI and pyridine, etc.).
A compound of Formula (I) having the structure of a compound of Formula 2.9 can be assembled through first cross-coupling of an Intermediate 3.4 with Intermediate 9.1 using a suitable transition metal catalyst (e.g. palladium, etc.) (Scheme 9). The benzyl ether can then be removed through reduction using H2 and a suitable catalyst (Pd/C, etc.) to yield intermediate 9.2. Intermediate 9.2 can then be alkylated using a suitable base (K2CO3, Cs2CO3, Ag2CO3, etc.) a suitable electrophile represented by intermediate 9.3 where X91 can be —Cl, —Br, I, or —OTs. Intermediate 2.8 can be converted to the compound of Formula (I) having the structure of a compound of Formula 2.9 using standard ester hydrolysis conditions (e.g. LiOH, LiI and pyridine, etc.).

Intermediate 10.2 is then converted to intermediate 10.3 using a suitable transition metal catalyst (e.g. palladium, etc.). Intermediate 10.3 can be converted to the compound of Formula (I) having the structure of a compound of Formula 10.4 using standard ester hydrolysis conditions (e.g. LiOH, LiI and pyridine, etc.).

GLP-1R Activation—cAMP Assay 1
GLP-1R activation by compounds of the present disclosure was quantified by measuring cAMP increase in CHO cells stably expressing GLP-1R (MultiSpan product #C1267-1a). The cells were harvested and plated in growth medium (DMEM/F-12 (Corning product #10-090-CV) supplemented with 10% FBS (HyClone product #SH30071-03), penicillin/streptomycin (Corning product #30-002CI) and 10 μg/ml puromycin (Gibco product #A11138-03)) at 1,000 cells/well in a 384-well plate (Greiner product #781080). The cells were then incubated overnight at 37° C., 5% CO2. The next day, the medium was removed and the cells were washed with DPBS (Corning product #21-031-CM) before adding the assay medium (HBSS, Corning product #21-023-CV) with 20 mM Hepes (Gibco product #15630-080) and 0.1% BSA (Rockland Immunochemicals product #BSA-1000)). Following the medium change, the cells were incubated for 1 hour at 37° C., 5% CO2. The tested GLP-1 compound was added to the cells in a 10-point dose response followed by a 30-minute incubation at 37° C., 5% CO2. cAMP concentration increase was then detected using Cisbio's cAMP Gs Dynamic Kit (product #62AM4PEC) according to the manufacturer's protocol. The response was plotted against the log of the agonist concentration and fitted to a sigmoidal equation to determine the EC50.

The cells are then incubated for 30 minutes at 37° C., 5% CO2. cAMP concentration increase was then detected using Cisbio's cAMP Gs Dynamic Kit (product #62AM4PEC) according to the manufacturer's protocol. The response was plotted against the log of the agonist concentration and fitted to a sigmoidal equation to determine the EC50.
Compounds were run on one of the two GLP-1R Activation cAMP assays and the result are listed in Table 3. below.
Examples 54 and 253 were tested along with comparative examples CE-1 and CE-2.
Compounds CE-2, Example 54 or Example 253 were combined with a mixture of 10% NMP (v:v) and 90% PEG300 (v:v), and the mixture was stirred until a homogeneous solution was obtained (1 mg/mL final concentration of test article).
Compound CE-1 was combined with a mixture of 15% 2-hydroxypropyl-o-cyclodextrin (w:v) and 85% Mili-Q water (v:v), and the mixture was stirred until a homogeneous solution was obtained (0.5 mg/mL final concentration of test article).
Young adult non-naive Cynomolgus monkeys with weight about 2.5-5 kg (n=1-3/test article/route) were fasted overnight and then dosed with either CE-1 (at 1 mg test article per kg animal weight), CE-2 (at 2 mg test article per kg animal weight), Example 54 (at 2 mg test article per kg animal weight), or Example 253 (at 2 mg test article per kg animal weight). Food was supplied approximately 4 hours post dose and animals were provided with free access to water all the time. Animals were restrained at designated time points for blood sampling. Approximately 500 μL of blood samples was taken via cephalic or saphenous vein into EDTA-K2 tubes. For oral administration (PO): blood samples were generally collected pre-dose, and at 15 min, 30 min, 1 hr, 2 hr, 4 hr, 8 hr, 12 hr, and 24 hr time points after dosing. Blood was maintained on wet ice, in chilled cryoracks, or at approximately 5° C. prior to centrifugation to obtain plasma. Centrifugation was conducted within 1 hour of collection. Plasma (approximately 200 μL) was placed into a micronic tubes containing 4 μL of formic acid (the final concentration of formic acid in plasma was approximately 2%) and samples were vortex mixed. Samples were maintained on dry ice prior to storage at approximately −70° C.
LC-MS/MS assays were utilized to quantify the concentration of the test articles in plasma as follows.
50 μL plasma sample was mixed with 350 μL of ACN combined with an internal standard. The mixture was then vortexed for about 1-5 min, and centrifuged at about 4,000-5,800 rpm for about 10-15 mm. An aliquot of 1 μL supernatant was used for LC-MS/MS analysis.
MS conditions: A Sciex API 6500 equipped with electrospray ionization in the positive ion selected reaction monitoring mode was used for detection.
