Description

GLUCAGON RECEPTOR AGONISTS WITH ARYL LINKERS AND THEIR USE AS THERAPIES TECHNICAL FIELD

[0001] Disclosed herein are compounds which are glucagon receptor agonists. These compounds may be useful as therapeutic agents, either as a monotherapy or in combination with another therapeutic agent, for preventing or treating a disease or condition through the modulation of the glucagon receptor. BACKGROUND OF THE INVENTION

[0002] Over the past several decades, the prevalence of diseases such as type 2 diabetes, obesity, and overweight has continued to rise. T2D mellitus (T2DM) is the most common form of diabetes accounting for approximately 90% of all diabetes. T2DM is characterized by high blood glucose levels caused by insulin resistance. The current standard of care for T2DM includes diet and exercise, and treatment with oral and injectable medications including incretin- based therapies, such as glucagon-like-peptide-1 receptor agonists (GLP-1 RA) and glucose- dependent insulinotropic polypeptide receptor agonists (GIP RA). Incretin-based therapies such as GLP-1 RA and GIP RA have also been approved for treating obesity and overweight.

[0003] Despite the availability of these therapies, blood glucose levels in many patients with T2DM still remain inadequately controlled. Uncontrolled diabetes leads to several conditions that impact morbidity and mortality of patients. One of the main risk factors for T2DM is obesity or overweight. It is documented that a decrease in body adiposity leads to improvement in obesity-associated co-morbidities including hyperglycemia and cardiovascular events. Therefore, additional therapies effective in glucose control and weight reduction, for example, through the modulation of the glucagon receptor, are needed for better disease management.

[0004] Glucagon is a twenty-nine amino acid peptide which is secreted from the cells of the pancreas into the hepatic portal vein thereby exposing the liver to higher levels of this hormone than non-hepatic tissues. Plasma glucagon levels decrease in response to hyperglycemia, hyperinsulinemia, elevated plasma non-esterified fatty acid levels and somatostatin whereas glucagon secretion is increased in response to hypoglycemia and elevated plasma amino acidlevels. Glucagon, through activation of its receptor, is a potent activator of hepatic glucose production by activating glycogenolysis and gluconeogenesis.

[0005] The glucagon receptor GCGR is a 62 kDa protein that is activated by glucagon and is a member of the class B G-protein coupled family of receptors. Other related G-protein coupled receptors include glucagon-like peptide-1 receptor (GLP-1), glucagon-like peptide-2 receptor (GLP-2) and gastric inhibitory polypeptide receptor. The glucagon receptor is encoded by the GCGR gene in humans and these receptors are mainly expressed in the liver with lesser amounts found in the kidney, heart, adipose tissue, spleen, thymus, adrenal glands, pancreas, cerebral cortex and gastrointestinal tract. Stimulation of the glucagon receptor results in activation of adenylate cyclase and increased levels of intracellular cAMP. Regulation of the glucagon receptor can play an important role in the treatment of T2DM, obesity or overweight, and other conditions modulated by this receptor. Despite advancement of T2DM and obesity therapies, there remains a need for treatments for T2DM with effective glucose control, and for weight loss benefits and a favorable side effect profile. SUMMARY OF THE INVENTION

[0006] Advantageously, glucagon agonists described herein have favorable properties allowing for administration of doses that provide sufficient activity at the glucagon receptor to provide the benefits of agonism of that receptor while avoiding unwanted side effects.

[0099] In the schemes below, unless otherwise indicated, RA1, RA2, RA3, RA4, R4, R4’, R5, R5’, R6, R7, and B are as defined in Formula I. The reagents and starting materials are either commercially available or may be prepared by methods well known to one of ordinary skill in the art, some of which are presented in the preparations below. Without limiting the scope of the invention, the following schemes, preparations, and examples are provided to further illustrate the invention. Scheme 1

[0100] Schem -1-en-4-one intermediate (5) beginning with a suitable protected amine (1). The PG moiety on the amine (1) is a standard amine protecting group well known to a skilled artisan, including carbamate protecting groups such as Boc. The amine (1) is reacted with NH4OAc and KCN in an appropriate solvent, such as EtOH, and stirred for at least 48 h at 80 °C. The resulting intermediate (2) is oxidized in the presence of an appropriate oxidizing agent, such as H2O2, and a suitable base, such as NaOH, in an appropriate solvent, such as EtOH, DMSO or MeOH to give amide intermediate (3). Intermediate (3) is then reacted with a suitable acyl chloride (R6- COCl) in the presence of an organic base, such as TEA, in a suitable solvent, such as THF, or a suitable acid (R6-CO2H) using amide coupling conditions know to the skilled artisan, e.g. HATU and an organic base such as DIEA in a solvent such as DMF, and then cyclized to form intermediate (4) using an alkoxide base such as sodium ethoxide / EtOH or KOtBu / EtOH at elevated temperature.

[0101] The removal of the PG moiety on the amine of the amide (4) is achieved under conditions standard to the art. For example, where PG is Boc the intermediate amine (5) is obtained by reacting a suitable acid, such as HCl in 1,4-dioxane, in an appropriate solvent, such as DCM. Scheme 2[ Scheme 2 by reacting the 1,3,8-triazaspiro[4.5]dec-1-en-4-one intermediate (5) with intermediate (6) where X1is a halide such as bromine, or silane such as -Si(CH3)3, and X2is a halide such as chlorine, bromine, or iodine. If X1is bromine, this transformation occurs by reacting (6) with lithium bis(trimethylsilyl)amide, followed by amine intermediate (5) in a solvent such as 1,4- dioxane at an elevated temperature to give intermediate (7) wherein X2is Br, or I. If X1is a silane, (6) can be reacted with amine (5) using CsF in a solvent such as ACN to give (7). The halogen in the resulting intermediate (7) may be reacted with (8) where X3is a boronic acid or boronic ester, under standard Suzuki coupling conditions to give (9). Alternatively, the halogen X2in intermediate (7) can be converted to a boronic ester using bis(pinacolato)diborane, a palladium catalyst, a carbonate base such as K2CO3, 2-ethyl hexanoic acid, and a solvent such as 2-methyltetrahydrofuran. Suzuki coupling conditions with (8) where X3is a halogen gives compound (9). Scheme 3whose use is described in Scheme 1, and in which “Z” represents various substituent groups on R6as described in Formula (I), in particular alkyl and cycloalkyl groups. Acid 10 is reacted with CDI and TEA, and then with intermediate 11 (wherein “PG” is an ester protecting group such asmethyl or ethyl) using an amine base such as TEA to give intermediate 12. Intermediate 12 is then reacted with intermediate 13 using ammonium trifluoroacetate and TFA in a solvent such as toluene at elevated temperature to give pyridine intermediate 14. Hydrolysis of the ester under aqueous basic conditions (e.g. using NaOH and water and organic solvents e.g. THF and / or MeOH) gives acid 15.
