Patent Description:
Diabetes is a common type of metabolic disease characterized by hyperglycemia. Several major types of diabetes are caused by complex interactions between genetic and environmental factors. The factors leading to hyperglycemia include the decrease of insulin secretion, the decrease of glucose utilization and the increase of glucose output, and the dominance of these factors varies according to the etiology of diabetes. Metabolic abnormalities related to diabetes lead to secondary pathophysiological changes in multiple systems throughout the body. Long-term abnormal blood glucose levels can lead to serious complications, including cardiovascular disease, chronic renal failure, retinal injury, nerve injury, microvascular injury and obesity and the like. Diabetes is classified based on different pathological processes leading to hyperglycemia, and can be divided into two main types: type <NUM> diabetes and type <NUM> diabetes. In the development of the disease, type <NUM> and type <NUM> diabetes are preceded by a phase of abnormal glucose homeostasis. Type <NUM> diabetes is the result of complete or almost complete insulin deficiency. Type <NUM> diabetes is a group of heterogeneous diseases, manifested by varying degrees of insulin resistance, decreased insulin secretion, and increased glucose production. In the early stages of diabetes treatment, diet control and exercise therapy are the preferred control options of blood glucose. When control of blood glucose is difficult to achieve with these methods, treatment with insulin or oral hypoglycemic drugs is required. Currently, drugs used in the treatment of diabetes include insulin, insulin secretagogue, metformin, insulin sensitizers, α-glucosidase inhibitor, dipeptidyl peptidase-IV inhibitor (liptins), sodium-glucose cotransport protein (SGLT2) inhibitor, and glucagon-like peptide-<NUM> (GLP-<NUM>) receptor agonist and the like. These drugs have good therapeutic effects, but there are still safety issues in long-term treatment, for example, biguanides can easily cause lactic acidosis; sulfonylureas can cause symptoms of hypoglycemia; insulin sensitizers can cause edema, heart failure, and weight gain; α-glucosidase inhibitors can cause abdominal pain, bloating, diarrhea and other symptoms; sodium-glucose cotransporter protein (SGLT2) inhibitors increase the risk of urinary and reproductive system infections and the like. Therefore, there is an urgent need to develop a safer and more effective novel hypoglycemic drug to meet the needs of diabetes treatment.

Glucagon-like peptide-<NUM> receptor (GLP-1R) is one of the most important therapeutic targets for type <NUM> diabetes. GLP-1R belongs to the subfamily of G protein-coupled receptor B cluster and is widely expressed in the stomach, small intestine, heart, kidney, lung, brain and other tissues in the body. In islet cells, GLP-1R mainly promotes the release of insulin, increases the regeneration of islet B cells, inhibits the apoptosis of B cells, and reduces the release of glucagon. In tissues such as the gastrointestinal tract, GLP-1R can inhibit gastrointestinal peristalsis and gastric juice secretion by combining with its agonists, delaying gastric emptying, and increasing satiety. In nerve tissue, small molecule GLP-1R agonists can penetrate into the brain to activate the subset of neurons expressing GLP-1R, protect nerve cells from apoptosis and enhance learning and memory abilities. Moreover, GLP-1R can also control food intake to lose weight. GLP-<NUM> receptor agonists or endogenous GLP-<NUM> activity enhancers have been approved for the treatment of type <NUM> diabetes. Such drugs do not cause hypoglycemia because the secretion of insulin stimulated by secretin is glucose-dependent. Exenatide is a synthetic peptide, such peptide was originally found in the saliva of a poisonous lizard and is an analog of GLP-<NUM>. Compared with natural GLP-<NUM>, exenatide has a different amino acid sequence, which makes exenatide resistant to the enzyme [dipeptidase IV (DPP-IV)] that degrades GLP-<NUM>. Therefore, exenatide has prolonged GLP-<NUM>-like activity and can bind to GLP-<NUM> receptors in islets, gastrointestinal tract and brain. Liraglutide, another GLP-<NUM> receptor agonist, is almost identical to natural GLP-<NUM> except that it replaces one of the amino acids and adds a fatty acyl, the fatty acyl can promote its binding with albumin and plasma proteins and prolong its half-life. GLP-<NUM> receptor agonists increase glucose-stimulated insulin secretion, inhibit glucagon, and delay gastric emptying. These drugs do not increase body weight, in fact, most patients will lose weight and lose appetite to some extent.

DPP-IV inhibitors inhibit the degradation of natural GLP-<NUM>, thereby enhancing the effect of secretin. DPP-IV, fully expressed on the cell surface of endothelial cells and some lymphocytes, can degrade a variety of polypeptides (not just GLP-<NUM>). DPP-IV inhibitors promote insulin secretion without lowering blood glucose, without gaining weight, and are more advantageous in reducing blood glucose after meals. Patients using GLP-<NUM> receptor agonists had higher levels of GLP-<NUM> action in their bodies than those using DPP-IV inhibitors.

Developing small molecule GLP-<NUM> receptor agonists with oral activity can effectively avoid long-term self-injection and has good compliance. Small molecule GLP-<NUM> receptor agonists control blood glucose through multiple pathways of glucose metabolism and excretion, it is expected that safer and more effective novel hypoglycemic drugs can be developed to meet the needs of diabetes treatment.

Unless otherwise specified, the following terms and phrases when used herein have the following meanings. A specific term or phrase should not be considered indefinite or unclear in the absence of a particular definition, but should be understood in the ordinary sense. When a trading name appears herein, it is intended to refer to its corresponding commodity or active ingredient thereof. The term "pharmaceutically acceptable" is used herein in terms of those compounds, materials, compositions, and/or dosage forms, which are suitable for use in contact with human and animal tissues within the scope of reliable medical judgment, with no excessive toxicity, irritation, an allergic reaction or other problems or complications, commensurate with a reasonable benefit/risk ratio. The term "pharmaceutically acceptable salt" refers to a salt of the compound of the present disclosure that is prepared by reacting the compound having a specific substituent of the present disclosure with a relatively non-toxic acid or base. When the compound of the present disclosure contains a relatively acidic functional group, a base addition salt can be obtained by bringing the neutral form of the compound into contact with a sufficient amount of base in a pure solution or a suitable inert solvent. The pharmaceutically acceptable base addition salt includes a salt of sodium, potassium, calcium, ammonium, organic amine or magnesium, or similar salts. When the compound of the present disclosure contains a relatively basic functional group, an acid addition salt can be obtained by bringing the neutral form of the compound into contact with a sufficient amount of acid in a pure solution or a suitable inert solvent.

Certain specific compounds of the present disclosure contain both basic and acidic functional groups, thus can be converted to any base or acid addition salt.

The pharmaceutically acceptable salt of the present disclosure can be prepared from the parent compound that contains an acidic or basic moiety by conventional chemical method. Generally, such salt can be prepared by reacting the free acid or base form of the compound with a stoichiometric amount of an appropriate base or acid in water or an organic solvent or a mixture thereof.

Unless otherwise specified, the term "isomer" is intended to include geometric isomers, cis-trans isomers, stereoisomers, enantiomers, optical isomers, diastereomers and tautomers.

The compounds of the present disclosure may exist in specific geometric or stereoisomeric forms. The present disclosure contemplates all such compounds, including cis and trans isomers, (-)- and (+)-enantiomers, (R)- and (S)-enantiomers, diastereomers isomers, (D)-isomers, (L)-isomers, and racemic and other mixtures thereof, such as enantiomers or diastereomeric enriched mixtures, all of which are within the scope of the present disclosure. Additional asymmetric carbon atoms may be present in substituents such as alkyl. All these isomers and their mixtures are included within the scope of the present disclosure.

Unless otherwise specified, the term "enantiomer" or "optical isomer" refers to stereoisomers that are mirror images of each other.

Unless otherwise specified, the term "cis-trans isomer" or "geometric isomer" is caused by the inability to rotate freely of double bonds or single bonds of ring-forming carbon atoms.

Unless otherwise specified, the term "diastereomer" refers to a stereoisomer in which a molecule has two or more chiral centers and the relationship between the molecules is not mirror images.

Unless otherwise specified, "(+)" refers to dextrorotation, "(-)" refers to levorotation, and or "(±)" refers to racemic.

Unless otherwise specified, the absolute configuration of a stereogenic center is represented by a wedged solid bond (<IMG>) and a wedged dashed bond (<IMG>), and the relative configuration of a stereogenic center is represented by a straight solid bond (<IMG>) and a straight dashed bond (<IMG>), a wave line (<IMG>) is used to represent a wedged solid bond (<IMG>) or a wedged dashed bond (<IMG>), or the wave line (<IMG>) is used to represent a straight solid bond (<IMG>) or a straight dashed bond (<IMG>).

Unless otherwise specified, the terms "enriched in one isomer", "enriched in isomers", "enriched in one enantiomer" or "enriched in enantiomers" refer to the content of one of the isomers or enantiomers is less than <NUM>%, and the content of the isomer or enantiomer is greater than or equal to <NUM>%, or greater than or equal to <NUM>%, or greater than or equal to <NUM>%, or greater than or equal to <NUM>%, or greater than or equal to <NUM>%, or greater than or equal to <NUM>%, or greater than or equal to <NUM>%, or greater than or equal to <NUM>%, or greater than or equal to <NUM>%, or greater than or equal to <NUM>%, or greater than or equal to <NUM>%, or greater than or equal to <NUM>%, or greater than or equal to <NUM>%, or greater than or equal to <NUM>%.

Unless otherwise specified, the term "isomer excess" or "enantiomeric excess" refers to the difference between the relative percentages of two isomers or two enantiomers. For example, if the content of one isomer or enantiomer is <NUM>%, and the content of the other isomer or enantiomer is <NUM>%, the isomer or enantiomer excess (ee value) is <NUM>%.

Optically active (R)- and (S)-isomer, or D and L isomer can be prepared using chiral synthesis or chiral reagents or other conventional techniques. If one kind of enantiomer of certain compound of the present disclosure is to be obtained, the pure desired enantiomer can be obtained by asymmetric synthesis or derivative action of chiral auxiliary followed by separating the resulting diastereomeric mixture and cleaving the auxiliary group. Alternatively, when the molecule contains a basic functional group (such as amino) or an acidic functional group (such as carboxyl), the compound reacts with an appropriate optically active acid or base to form a salt of the diastereomeric isomer which is then subjected to diastereomeric resolution through the conventional method in the art to obtian the pure enantiomer. In addition, the enantiomer and the diastereoisomer are generally isolated through chromatography which uses a chiral stationary phase and optionally combines with a chemical derivative method (such as carbamate generated from amine).

The compound of the present disclosure may contain an unnatural proportion of atomic isotope at one or more than one atom(s) that constitute the compound. For example, the compound can be radiolabeled with a radioactive isotope, such as tritium (<NUM>H), iodine-<NUM> (<NUM>I) or C-<NUM> (<NUM>C). For another example, deuterated drugs can be formed by replacing hydrogen with heavy hydrogen, the bond formed by deuterium and carbon is stronger than that of ordinary hydrogen and carbon, compared with non-deuterated drugs, deuterated drugs have the advantages of reduced toxic and side effects, increased drug stability, enhanced efficacy, extended biological half-life of drugs and the like. All isotopic variations of the compound of the present disclosure, whether radioactive or not, are encompassed within the scope of the present disclosure.

The term "optional" or "optionally" means that the subsequent event or condition may occur but not requisite, that the term includes the instance in which the event or condition occurs and the instance in which the event or condition does not occur.

The term "substituted" means one or more than one hydrogen atom(s) on a specific atom are substituted with the substituent, including deuterium and hydrogen variables, as long as the valence of the specific atom is normal and the substituted compound is stable. When the substituent is an oxygen (i.e., =O), it means two hydrogen atoms are substituted. Positions on an aromatic ring cannot be substituted with a ketone.

The term "optionally substituted" means an atom can be substituted with a substituent or not, unless otherwise specified, the type and number of the substituent may be arbitrary as long as is chemically achievable.

When any variable (such as R) occurs in the constitution or structure of the compound more than once, the definition of the variable at each occurrence is independent. Thus, for example, if a group is substituted with <NUM>-<NUM> R, the group can be optionally substituted with up to two R, wherein the definition of R at each occurrence is independent. Moreover, a combination of the substituent and/or the variant thereof is allowed only when the combination results in a stable compound.

When the number of a linking group is <NUM>, such as -(CRR)<NUM>-, it means that the linking group is a single bond.

When the number of substituent is <NUM>, it means that the substituent does not exist, for example, -A-(R)<NUM> means that its structure is actually A.

When a substituent is vacant, it means that the substituent does not exist, for example, when X is vacant in A-X, the structure of A-X is actually A.

When one of the variables is selected from a single bond, it means that the two groups linked by the single bond are connected directly. For example, when L in A-L-Z represents a single bond, the structure of A-L-Z is actually A-Z.

When the bond of a substituent can be cross-connected to two or more atoms on a ring, the substituent can be bonded to any atom on the ring, for example, the structural moiety
<CHM>
or
<CHM>
means that the substitution can take place with the substituent R at any position on cyclohexyl or cyclohexadiene. When the enumerative substituent does not indicate by which atom it is linked to the group to be substituted, such substituent can be bonded by any atom thereof. For example, when pyridyl acts as a substituent, it can be linked to the group to be substituted by any carbon atom on the pyridine ring.

When the enumerative linking group does not indicate the direction for linking, the direction for linking is arbitrary, for example, the linking group L contained in
<CHM>
is -M-W-, then -M-W- can link ring A and ring B to form
<CHM>
in the direction same as left-to-right reading order, and form
<CHM>
in the direction contrary to left-to-right reading order. A combination of the linking groups, substituents and/or variables thereof is allowed only when such combination can result in a stable compound.

Unless otherwise specified, when a group has one or more linkable sites, any one or more sites of the group can be linked to other groups through chemical bonds. When the linking site of the chemical bond is not positioned, and there is H atom at the linkable site, then the number of H atom at the site will decrease correspondingly with the number of the chemical bond linking thereto so as to meet the corresponding valence. The chemical bond between the site and other groups can be represented by a straight solid bond (<IMG>), a straight dashed bond (<IMG>) or a wavy line ( ). For example, the straight solid bond in -OCH<NUM> means that it is linked to other groups through the oxygen atom in the group; the straight dashed bonds in
<CHM>
means that it is linked to other groups through the two ends of nitrogen atom in the group; the wave lines in
<CHM>
means that the phenyl group is linked to other groups through carbon atoms at position <NUM> and position <NUM>;
<CHM>
means that it can be linked to other groups through any linkable sites on the piperidinyl by one chemical bond, including at least four types of linkage, including
<CHM>.

Even though the H atom is drawn on the-N-,
<CHM>
still includes the linkage of
<CHM>
merely when one chemical bond was connected, the H of this site will be reduced by one to the corresponding monovalent piperidinyl.

Unless otherwise specified, the number of atoms in a ring is usually defined as the number of ring members, for example, "<NUM>-<NUM> membered ring" refers to a "ring" in which <NUM>-<NUM> atoms are arranged around.

Unless otherwise specified, the term "C<NUM>-<NUM> alkyl" refers to a linear or branched saturated hydrocarbon group composing of <NUM> to <NUM> carbon atoms. The C<NUM>-<NUM> alkyl includes C<NUM>-<NUM> and C<NUM>-<NUM> alkyl and the like; it can be monovalent (such as methyl), divalent (such as methylene) or multivalent (such as methine). Examples of C<NUM>-<NUM> alkyl include but are not limited to methyl (Me), ethyl (Et), propyl (including n-propyl and isopropyl) and the like.

Unless otherwise specified, the term "C<NUM>-<NUM> alkoxy" refers to an alkyl composing of <NUM> to <NUM> carbon atoms that are connected to the rest of the molecule through an oxygen atom. The C<NUM>-<NUM> alkoxy includes C<NUM>-<NUM>, C<NUM>-<NUM>, C<NUM> and C<NUM> alkoxy and the like. Examples of C<NUM>-<NUM> alkoxy include, but are not limited to, methoxy, ethoxy, propoxy (including n-propoxy and isopropoxy) and the like.
