Description
GIP Receptor Agonist Compounds FIELD OF THE INVENTION
[0001] This invention relates to cyclopropane-carboxamide compounds having agonist activity at the human glucose-dependent insulinotropic polypeptide (GIP) receptor, pharmaceutically acceptable salts thereof, pharmaceutical compositions, and therapeutic uses of the compounds. The compounds may be useful in the treatment of type 2 diabetes mellitus (T2DM). Also, the compounds may be useful in the treatment of obesity. BACKGROUND OF THE INVENTION
[0002] Over the past several decades, the prevalence of diabetes has continued to rise. T2DM is the most common form of diabetes, accounting for approximately 90% of all diabetes. T2DM is characterized by high blood glucose levels associated mainly with insulin resistance. The current standard of care for T2DM includes diet and exercise, treatment with oral medications, and injectable glucose-lowering drugs, including incretin-based therapies such as Glucagon-like peptide-1 (GLP-1) receptor agonists. When treatment with oral medications and incretin-based therapies are insufficient, insulin treatment is considered. Despite the advances in treatment available today, many patients with T2DM are unable to reach their glycemic control goals. Uncontrolled diabetes leads to several conditions associated with increased morbidity and mortality of patients. There is a need for alternative treatments to enable more patients with T2DM to reach their glycemic treatment goals.
[0003] Obesity is a complex medical disorder resulting in excessive accumulation of adipose tissue mass. Today obesity is a global public health concern that is associated with undesired health outcomes and morbidities. Desired treatments for patients with obesity should reduce excess body weight, improve obesity-related co-morbidities, and maintain long-term weight reduction. There is a need for alternative treatment options to induce therapeutic weight loss in patients in need of such treatment.
[0004] Both GLP-1 and GIP are incretins, gastrointestinal hormones that regulate blood glucose by enhancing glucose-stimulated insulin secretion. Incretins are also involved in gastric emptying and the regulation of food intake. Incretin-based therapies have provided T2DM and obesity patients with valuable treatment options. Tirzepatide, an agonist having activity at boththe GLP-1 receptor (GLP-1R) and GIPR, has been approved as an injectable for the treatment of T2DM (MounjaroTM) and for chronic weight management in adults with obesity (ZepboundTM).
[0005] Injectable agents, however, have a number of drawbacks including inconvenience, pain, and the potential for injection site irritation. Therefore, patients often prefer orally administered drugs. Whilst there are a number of GLP-1R agonists in clinical development for oral administration including, for example, orforglipron (Frias et al., Lancet 2023: 402: 472-83), there are currently no such GIPR agonists.
[0006] There remains a need for alternative treatments for T2DM and obesity. In particular, there is a need for GIPR agonist compounds, especially GIPR agonist compounds which can be administered orally. SUMMARY OF THE INVENTION

[0168] Scheme 3 shows the preparation of intermediates 17 and 21, which are useful for the preparation of compounds of the present invention. Aryl / heteroaryl halide 14 (where “Z” is a halogen such as bromine) is coupled with trifluoroborate intermediate 15 (where “W” is an alkyl group such as methyl, ethyl, or tert-butyl) using a palladium catalyst such as cataCXium Pd G4 and a carbonate base such as Cs2CO3in an aqueous solvent mix such as toluene / water at elevated temperature to give 16. Alternatively, vinyl intermediate 18 is reacted with diazo compound 19 (where “W” is an alkyl group such as methyl, ethyl, or tert-butyl) in the presence of rhodium(II) acetate in a solvent such as THF to give 20. Ester intermediates 16 and 20 are then converted to acids 17 and 21, respectively, under conditions known to the person skilled in the art. For example tert-butyl esters are converted to acids under acidic conditions (e.g. TFA in chlorinated solvent such as DCM), and methyl and ethyl esters are hydrolyzed under aqueous basic conditions (e.g. LiOH in aqueous THF, at RT or at elevated temperature).88'
[0169] Scheme 4 shows the preparation of compounds of the present invention. Alkyl bromide 22 is reacted with tetrahydrothiophene 23 in a solvent such as acetone or ACN, optionally with addition of silver tetrafluoroborate to give 24, followed by reaction with 3- methylenedihydrofuran-2(3H)-one 25 using a base such as lithium bis(trimethylsilyl)amide in a solvent such as THF to give intermediate 26. Intermediate 26 is reacted with SOCl2, benzyltriethylammonium chloride, and BF3etherate in a solvent such as DCE, then reacted with amine intermediate 27 using an organic base such as TEA in a solvent such as DCM to give intermediate 28. Intermediate 28 is then cyclized to spirocyclic compound of Formula IX using a carbonate base such as Cs2CO3in a solvent such as NMP.H
[0170] Scheme 5 shows the preparation of amino acid derivatives which are useful for the preparation of compounds of the present invention. Alkyl iodide 30 is reacted with aryl / heteroaryl iodide 31 (where “W” is an alkyl group such as methyl, ethyl, or tert-butyl and “PG” is a protecting group such as Boc or benzyloxycarbonyl) using pyridine-2,6- bis(carboximidamide) dihydrochloride, nickel(II) chloride, and zinc in a solvent such as DMA to give 32. Alternatively, phosphoryl compound 33 (where “W” and “PG” are as described above) undergoes a Horner-Wadsworth-Emmons reaction with aldehyde 34 using a base such as DBU in a solvent such as DCM, then the resulting olefin is hydrogenated to give 32. Olefin reduction conditions are known to a person of skill in the art, and can be achieved asymmetrically by hydrogenation with a catalyst such as Rh-COD-[(R)-MaxPhos]-BF4 in a fluorinated alkane solvent (e.g. 1,1,1,3,3,3-hexafluoroisopropanol and 2,2,2-trifluoroethanol) at elevated temperature. If orthogonal protecting groups are chosen for “PG” and “W”, protected amino acid 32 can be deprotected under conditions known to a person of skill in the art to either to amine 35 or acid 36. For example, where “W” is methyl or ethyl, aqueous LiOH in a solvent such as TFH converts 32 to acid 36, and where “PG” is Boc 36 could be prepared from 32 under acidic conditions (e.g. using a solution of HCl in 1,4-dioxane). Acid 36 can be converted to N-methyl amino acid 38 by first reacting it with paraformaldehyde using p-toluene sulfonic acid in a solvent such as toluene at elevated temperature to give cyclic compound 37, which is then opened with TFA, HCl (as a solution in 1,4-dioxane), and triethylsilane in DCE to give 38.88'8

Reaction conditions used to deprotect Boc or benzyloxycarbonyl protected amines are known to a person of skill in the art, which can include reacting a Boc-protected amine with HCl in 1,4-dioxane or reacting a benzyloxycarbonyl- protected amine with H2 in the presence of palladium on carbon catalyst in an alcohol solvent. Reaction conditions used to convert carboxylic esters to carboxylic acids are also known to those skilled in the art. For example, methyl and ethyl esters can be hydrolyzed to carboxylic acids using an aqueous carbonate base at elevated temperature. Amine 39 (where “PG” is a protecting group such as Boc or benzyloxycarbonyl) is coupled with 40 to give 41, which is then deprotected and coupled with 42 to give 44. Alternatively, 41 is reacted with Lawesson’s reagentin an organic solvent such as THF at elevated temperature to give 43, which is then deprotected and coupled with 42 to give 45. 8 8'

[0173] Scheme 8 shows the preparation of compounds of the present invention starting with intermediate 26, which is reacted with SOCl2, benzyltriethylammonium chloride, and BF3etherate in a solvent such as DCE, then reacted with amine intermediate 49 using an organic base such as TEA in a solvent such as THF and / or DMA to give intermediate 50. Intermediate 50 is then cyclized to spirocyclic compound 51 using a carbonate base such as Cs2CO3in a solvent such as NMP or THF. The ester 51 is hydrolyzed using aq. LiOH in tert-butanol to give 52, which is then coupled with amine 40 under amide coupling conditions known to one skilled inthe art, such as DEPBT and N-methylmorpholine in a solvent such as DMA to give compound 44.

[0174] In Schemes 3, 4, 6, 7, and 8, R1can be introduced onto ring A at various points in the synthetic routes if ring A bears a halogen by metal catalyzed cross-coupling reactions with coupling partner intermediates bearing R1as defined in Formula IX, or groups which can be converted to R1in subsequent steps. Scheme 9 shows these synthetic steps. For example, if ring A bears a halogen (intermediate 59 where “Z” is a halogen) it can be coupled with boronic acids (e.g. intermediate 58 or analogous boronic ester where R1is a heterocycle as defined in Formula IX) using a palladium catalyst (e.g. Pd(dppf)Cl2) and a carbonate base (e.g. Cs2CO3) in an organic / aqueous solvent mix (e.g.1,4-dioxane / water) to give 60. An alternate approach is to react 59 with bis(pinacolato)diboron using a palladium catalyst such as Pd(dppf)Cl2and a base such as KOAc in a solvent such as 1,4-dioxane at elevated temperature to give boronate intermediate 61. Intermediate 61 can then be coupled with 62 (where “Z” is a halogen) under palladium coupling conditions (e.g. conditions described for the coupling of 58 and 59).
[0175] Alternatively, tert-butyl carbamate 57 can be coupled with 59 using a palladium catalyst such as Pd2(dba)3 with XPhos, and carbonate base (e.g. Cs2CO3) in an organic solvent such as 1,4-dioxane at elevated temperature to give 53. Boc deprotection using conditionsdescribed above (e.g. HCl in MeOH) gives an -NH2 group on ring A (intermediate 54), which can then be reacted with an isocyanate (e.g. intermediate 55) in the presence of an organic base (e.g. TEA) in a solvent such as DCM to give 56. Scheme 10 101
[0176] Scheme 10 shows the introduction of R11(where R11is an aromatic ring as defined in Formula IX) onto pyrazole 63, where “Z” is a halogen and 63 represents a compound also represented in Scheme 1, 4, 6, 7, or 8. Compound 63 can be coupled with boronic acid 64 (or an analogous boronic ester) using a palladium catalyst such as Pd(dppf)Cl2and a carbonate base such as Cs2CO3in an organic / aqueous solvent such as 1,4-dioxane and water at elevated temperature to give compound 65. Alternatively, halide 63 is reacted with tetrahydroxydiboron, XPhos Pd G3, and KOAc in MeOH and DCE to give boronic acid 66, which is then coupled with 67 (where “Z” is a halogen) using a palladium catalyst such as Pd(dtbpf)Cl2or XPhos Pd G3, and a carbonate base such as Na2CO3 or K2CO3 in an organic / aqueous solvent mix such as 1,4- dioxane / water or 1,4-dioxane / ethanol / water at elevated temperature to give compound 65.Ffrom Formula IX 6-membered heterocycle
[0177] In Schemes 3, 4, 6, 7, and 8, 6-membered heterocycles can be introduced as R1onto ring A at various points in the synthetic routes if ring A is a 2-chloro-substituted pyridine. Scheme 11 shows 2-chloropyridine analog 68 undergoing a SNAr reaction with 6-membered heterocycle 69 in an organic solvent such as DMSO at elevated temperature to give compound 70. Scheme 12 H
[0178] Scheme 12 shows the introduction of a methyl-dihydrogenphosphate group onto a R11group (as defined in Formula IX) comprising a 6-oxopyridazine ring. The 6-oxopyridazine compound 71 is reacted with di-tert-butyl(chloromethyl)phosphate using lithium tert-butoxide and sodium iodide in a solvent such as THF to give 72, which is then reacted with TFA in a solvent such as DCM to give 73.Scheme 13
[0179] Compounds of the present invention bearing an aliphatic alcohol substituent can be converted to dihydrogen phosphates (-OP(O)(OH)2) as shown in Scheme 13. Alcohol 74 is reacted with diallyl-N,N-diisopropylphosphoramidite using tetrazole in a solvent such as ACN at 0 °C and the mixture is treated with aq. H2O2or anhydrous tert-butyl hydroperoxide to give diallyl phosphate 75, which is then converted to phosphate 76 using phenylsilane and Pd(PPh3)4 in a solvent such as DCM at 0 °C.
