Description

An injectable formulation of a GLP-1R agonist and its preparation method

[0001] This disclosure claims priority to the following applications:

[0002] Chinese Patent Application No. 202510105532.X, entitled "An Injectable Form of a GLP-1R Agonist and a Method for its Preparation Thereof," was filed with the China National Intellectual Property Administration on January 21, 2025; Chinese Patent Application No. 202510096415.1, entitled "An Injectable Form of a GLP-1R Agonist and a Method for its Preparation Thereof," was filed with the China National Intellectual Property Administration on January 21, 2025; the entire contents of these documents are incorporated herein by reference. Technical Field

[0003] This invention relates to the pharmaceutical field, and more specifically, to formulations of GLP-1R agonists, methods for their preparation, and their uses. Background Technology

[0004] Glucagon-like peptide-1 (GLP-1) is a peptide hormone secreted by enteroendocrine cells in the gut in response to diet. GLP-1 is thought to play a role in postprandial blood glucose regulation by directly increasing diet-induced insulin secretion from pancreatic β-cells and by promoting satiety through delaying food transport through the intestines. GLP-1 mediates intracellular signaling via the GLP-1 receptor (GLP-1R), a member of the G protein-coupled receptor family located on the cell membrane, which, upon activation, leads to the accumulation of the second messenger cyclic adenosine monophosphate (cAMP). Nonalcoholic steatohepatitis (NASH) is associated with features of metabolic syndrome, including obesity, type 2 diabetes, insulin resistance, and cardiovascular disease.

[0005] GLP-1R agonists are currently being extensively investigated for their use in treating diabetes, obesity, and NASH. GLP-1R agonists include peptides such as exenatide, liraglutide, and duraglutide, which have been approved for the treatment of type 2 diabetes. These peptides are primarily administered via subcutaneous injection. Oral GLP-1 agonists are also being investigated for the treatment of type 2 diabetes. Some GLP-1R agonists, such as liraglutide, duraglutide, and exenatide, are resistant to the rapid degradation of dipeptidyl peptidase 4, resulting in a longer half-life than endogenous GLP-1.

[0006] In the treatment of GLP-1R-mediated diseases and conditions, there remains a need for compounds with desirable therapeutic properties, metabolic properties, and / or ease of administration. Summary of the Invention

For example, in some embodiments, an aryl group has 6 to 20 carbon atoms, 6 to 14 carbon atoms, 6 to 12 carbon atoms, or 6 to 10 carbon atoms. An aryl group includes a phenyl group. An aryl group also includes multiple condensed ring systems having about 9 to 20 carbon atoms (e.g., ring systems consisting of 2, 3, or 4 rings), wherein the rings are aromatic. Where valence requirements permit, the rings of multiple condensed ring systems may be interconnected by fusion bonds.

Therefore, a heteroaryl group (a single aromatic ring or multiple condensed ring system) can have approximately 1-20 carbon atoms and approximately 1-6 heteroatoms within the heteroaryl ring. For example, a tetrazolium group has 1 carbon atom and 4 nitrogen heteroatoms within the ring. Where valence requirements permit, the rings of multiple condensed ring systems can be interconnected by fusion bonds. It should be understood that the individual rings of multiple condensed ring systems can be interconnected in any order. It should be understood that the connection points of a heteroaryl group or a heteroaryl multiple condensed ring system can be any suitable atom of the heteroaryl group or a heteroaryl multiple condensed ring system, including carbon atoms and heteroatoms (e.g., nitrogen). It should also be understood that when referring to a member heteroaryl group of a certain atomic range (e.g., a heteroaryl group with 5 to 10 members), that atomic range refers to the total ring atoms of the heteroaryl group, including carbon atoms and heteroatoms. It should also be understood that the rings in a multi-condensation ring system may include an aryl ring fused to a heterocycle (e.g., a 3, 4, 5, 6, or 7-membered ring) having saturated or partially unsaturated bonds, the ring having about 1 to 6 cyclic carbon atoms and about 1 to 3 cyclic heteroatoms selected from oxygen, nitrogen, and sulfur in the ring. For example, 5-membered heteroaryl groups include thiazolyl groups, and 10-membered heteroaryl groups include quinolinyl groups.

The heteroaryl group may be unsubstituted or substituted.

[0056] "Cycloalkyl" is a monovalent or divalent single all-carbon ring or a system of multiple condensed all-carbon rings, wherein the ring in each instance is a non-aromatic saturated or unsaturated ring. For example, in some embodiments, the cycloalkyl has 3 to 12 carbon atoms, 3 to 10 carbon atoms, 3 to 8 carbon atoms, 3 to 6 carbon atoms, 3 to 5 carbon atoms, or 3 to 4 carbon atoms.
