A pharmaceutical composition according to the present invention can alleviate postprandial and fasting blood glucoses when administered into a subject.
The pharmaceutical composition according to the present invention can exhibit an effect of alleviating a blood lipid concentration and reducing body fat when administered into a subject.
Thus, the pharmaceutical composition according to the present invention may be advantageously used for preventing or treating diabetes or metabolic diseases associated therewith.
The features and advantages of the present invention as well as methods for achieving them will be apparent with reference to exemplary embodiments described in detail hereinafter. However, the present invention is not limited to the exemplary embodiments disclosed hereinafter, but will be implemented in various different forms. Hereinafter, the following exemplary embodiments will be suggested for better understanding of the present invention and are provided only for the purpose of completely illustrating the scope of the present invention to those skilled in the art, and thus the present invention will be defined only by the scope of the claims thereto.
A pharmaceutical composition for preventing or treating of diabetes or at least one disease selected from metabolic diseases associated therewith according to the present invention may include a compound represented by Formula 1 described above, pharmaceutically acceptable salts thereof, optical isomers thereof, hydrates thereof, solvates thereof or mixtures thereof; and at least one selected from a DPPIV inhibitor, a PPAR agonist, a SGLT2 inhibitor, an insulin secretagogue, a biguanidine drug and an alpha-glucosidase inhibitor.
The compound represented by Formula 1 may be a GPR119 ligand, and G protein-coupled receptor 119 (GPR119) may be one of G protein-coupled receptors (GPCRs) belonging to class A.
GRP119 may be activated by the GRP119 ligand to generate cAMP through Gαs among G protein subtypes, thereby inducing intracellular signaling.
GRP119 may have a high expression level in pancreatic beta cells and L cells of small intestines. Thus, when GPR119 of the pancreas is activated by administering the pharmaceutical composition of one embodiment, insulin secretion from pancreatic beta cells may increase, thereby reducing postprandial blood glucose. Thus, when GPR119 is activated, an effect of reducing blood lipids and body weights may be achieved in addition to glycemic control, thus contributing to alleviation of diabetes as well as metabolic diseases associated therewith.
Meanwhile, when GPR119 of small intestines is activated, the secretion of glucagon-like peptide-1 (GLP-1) from the small intestine L-cells may be increased. GLP-1 may exhibit a local action of inhibiting an influx of postprandial fat into bloodstream in small intestines.
In general, a GLP-1 receptor-like action may be modulated by high molecular compounds such as peptide ligands. However, since the pharmaceutical composition according to one embodiment includes the GPR119 ligand, which is a relatively low molecular compound, a GLP-1 receptor-like action may be implemented by an oral low molecular compound.
In the compound represented by Formula 1 in one embodiment, a halogen element may be substituted at positions 2 and 6 of a phenyl moiety of 4-(3-phenoxypropyl)piperidine. Accordingly, it may react more sensitively with GPR119 and a degree of GPR119 activation may be sharply higher than when other GPR119 ligands are administered.
The pharmaceutical composition of one embodiment may further include at least one selected from a DPPIV inhibitor, a PPAR agonist, a SGLT2 inhibitor, an insulin secretagogue, a biguanidine drug and an alpha-glucosidase inhibitor, in addition to the compound represented by Formula 1 described above. Thus, the pharmaceutical composition of one embodiment may be administered at least two drugs having different mechanisms, so as to reduce blood glucose through various mechanisms, thereby effectively controlling blood glucose.
Hypoglycemic agents currently applied to diabetic patients may include dipeptidyl peptidase IV (DPPIV) inhibitor, insulin sensitizer, sodium glucose co-transporter 2 (SGLT2) inhibitor for promoting urinary glucose excretion through a mechanism of inhibiting sodium-glucose co-transporter 2, insulin secretagogue, biguanidine drug (Biguanide), alpha-glucosidase inhibitor, etc.
Dipeptidyl peptidase IV (DPPIV) may be an enzyme which inactivates GLP-1 by removing two amino acids from an N-terminus of GLP-1 in the blood. GLP-1, of which secretion is induced by GPR119 ligand, may be inactivated by DPPIV enzyme within minutes after translocation into blood. Thus, when the GPR119 ligand increasing GLP-1 secretion and the DPPIV inhibitor blocking GLP-1 inactivation are used in combination, a duration of action of active GLP-1 in the blood may be extended along with a direct insulin secretion effect according to GPR119 activation of beta cells. Thus, a medicinal efficacy for alleviating metabolic diseases may be excellent. In other words, the DPPIV inhibitor may promote insulin secretion by prolonging a biological action of endogenous GLP-1, and thus may exhibit a postprandial hypoglycemic effect.
The DPPIV inhibitor may include, for example, at least one of sitagliptin, vildagliptin, saxagliptin, linagliptin, gemigliptin, anagliptin, teneligliptin, alogliptin, trelagliptin, omarigliptin, evogliptin, gosogliptin and dutogliptin.
An insulin sensitizer may be a drug for activating a peroxisome proliferator-activated receptor (PPAR). The PPAR agonist may include, for example, at least one of troglitazone, ciglitazone, rosiglitazone, pioglitazone, englitazone, elafibranor, saroglitazar and lobeglitazone.
Drug sodium glucose co-transporter 2 (SGLT2) inhibitor may promote glucose excretion by inhibiting glucose reabsorption in the kidneys in an insulin-independent manner. In addition, it may be accompanied by weight loss through calorie loss due to glucose excretion. The SGLT2 inhibitor may include, for example, at least one of canagliflozin, dapagliflozin, empagliflozin, ertugliflozin, ipragliflozin, luseogliflozin, remogliflozin, sergliflozin, sotagliflozin and tofogliflozin.
The insulin secretagogue may include a drug of sulfonylureas and non-sulfonylureas. For example, the insulin secretagogue of sulfonylureas may include at least one of glibenclamide (glyburide), glipizide, gliclazide, glimepiride, tolazamide, tolbutamide, acetohexamide, carbutamide, chlorpropamide, glibornuride, gliquidone, glisentide, glisolamide, glisoxepide, glyclopyamide, glycylamide and glipentide. The insulin secretagogue of a non-sulfonylurea structure may include at least one of repaglinide and nateglinide.
The biguanidine drug may inhibit gluconeogenesis in the liver. The biguanidine drug may include, for example, at least one of metformin, buformin and phenformin.
The alpha-glucosidase inhibitor may exhibit an action of delaying absorption of carbohydrates by inhibiting an enzyme activity that breaks down disaccharides into monosaccharides in intestines. The alpha-glucosidase inhibitor may include, for example, at least one of acarbose, voglibose, emiglitate and miglitol.
The pharmaceutical composition of one embodiment may include a complex of ingredients. Thus, when administering the pharmaceutical composition of one embodiment, not only a hypoglycemic effect but also an effect of reducing blood lipids and body weights may be achieved by two drugs having different mechanisms of action from each other.
Thus, it may exhibit an excellent effect of treating or preventing diabetes and metabolic diseases associated therewith compared to the case of administering individual ingredients alone.
Hereinafter, the pharmaceutical composition according to one embodiment of the present invention will be described in detail with reference to Examples and Comparative Examples.
Evaluation of Efficacy of Single Dose Administration in Normal Mice
Seven-weeks old ICR male mice fasted for at least 16 hours were administered with each of compound 1, sitagliptin or evogliptin as a DDPIV inhibitor alone, or administered with compound 1 in combination with one of sitagliptin and evogliptin. In both administration alone and co-administration, the mice were orally administered compound 1 at 0.3 mg/kg, sitagliptin at 10 mg/kg, and evogliptin at 0.2 mg/kg. At a time point of 30 minutes after drug administration, a glucose solution was orally loaded at 2 g/kg/10 ml.
To measure a change in plasma concentrations of active GLP-1 according to the combination, plasma at five minutes after glucose loading was separated using a container pretreated with the DPPIV inhibitor, and the plasma concentrations of active GLP-1 was quantified by using a GLP-1 (Active) ELISA kit (Millipore, Cat. EGLP-35K). To evaluate a drug response to postprandial blood glucose levels, blood glucose levels in whole blood collected from tail vein at a time point of 0, 15, 30, 60, 90, and 120 minutes after glucose challenge were measured using a Roche's AccuChek Active glucose meter. A time-blood glucose level response curve was obtained. In terms of a rate of change, a comparison was made between an area under time-blood glucose level curve in a control group administered with solvent only and an area under the time-blood glucose level curve in a drug administration group. The results thereof are shown in

Evaluation of Efficacy of Ten-Weeks Multiple Dose Administration in Diabetic Mice
Seven-weeks old ICR male mice were supplied with a high fat diet (Research Diets Inc., D12492; 60% kcal fat) for three weeks. The mice were divided into groups according to body weight, blood glucose and blood triglyceride concentration at a time point of three weeks after intraperitoneally injecting streptozotocin (STZ) at 80 mg/kg at the third week. Specifically, grouping was performed by selecting individuals of which nonfasting blood glucose level was increased 1SD (standard deviation) or higher and a plasma triglyceride level was increased 2SD or higher compared to normal mice. A drug-diet admixture, in which 100 mg/kg/day of compound 1 and 150 mg/kg/day of sitagliptin were mixed, was given to the selected group. The admixture was supplied for ten weeks. After that, fasting blood glucose levels, nonfasting blood glucose levels and plasma triglyceride concentrations were measured. Fasting and nonfasting blood glucose were measured from blood collected from tail vein using a Roche's AccuChek Active glucose meter. The plasma triglyceride concentration was measured from plasma collected after nonfasting autopsy using an automatic hematology analyzer (Konelab 20i).

Seven-weeks old ICR male mice fasted for at least 16 hours were administered with each of compound 1, dapagliflozin as an SGLT inhibitor, or glimepiride as an insulin secretagogue alone, or administered with compound 1 in combination with one of dapagliflozin and glimepiride. Glucose solution was orally loaded at 2 g/kg/10 ml at a time point of 30 minutes after orally administering each of compound 1 at 3 mg/kg, dapagliflozin at 0.3 mg/kg as a SGLT2 inhibitor, or glimepiride at 0.1 mg/kg as an insulin secretagogue alone or in combination. To evaluate a drug response to postprandial blood glucose level, a blood glucose in whole blood collected from tail vein at a time point of 0, 15, 30, 60, 90, and 120 minutes after glucose challenge in the blood was measured with a Roche's AccuChek Active glucose meter. A time-blood glucose level response curve was obtained. In terms of a rate of change, a comparison was made between an area under the time-blood glucose level curve in a control group administered with solvent only and an area under the time-blood glucose level curve in a drug administration group.

To induce insulin resistance, six-weeks old male C57BL/6J mice were supplied with a special diet of high fat, high fructose and high cholesterol (Research Diets Inc., D09100301) for at least 27 weeks. A drug-diet admixture was prepared so that diet-induced obese (DIO) and insulin resistant mice could be administered with each of compound 1 at 100 mg/kg/day and elafibranor at 30 mg/kg/day as a PPAR agonist alone or in combination. The prepared drug-diet admixture was supplied to mice for 12 weeks. Nonfasting blood glucose level was measured from plasma collected after autopsy at a time point of 12 weeks after drug administration using a Roche's AccuChek Active glucose meter.

Four-weeks old C57BL/6J male mice were supplied with a high fat diet (Research Diets Inc., D12492; 60% kcal fat) for ten weeks so as to induce insulin resistance. After acclimatization to drug administration for two weeks, the mice were assigned into each group based on body weight and body fat. Compound 1 was administered alone at 50 mg/kg twice a day to a compound 1 monotherapy group, and metformin was administered alone at 150 mg/kg twice a day to a metformin monotherapy group. The co-administration group was orally co-administered with compound 1 at 50 mg/kg and metformin at 150 mg/kg twice a day for three weeks. A body weight was measured over time until a time point of administration on day 16, and a body composition was sequentially measured by using a Minispec LF90II NMR spectrometer (Bruker Optics, Ettlingen, Germany) in the last week. Fasting blood glucose was measured from whole blood collected from a tail vein after fasting for six hours at the second week of administration using a Roche's AccuChek Active glucose meter. After administration for three weeks, a nonfasting autopsy was performed and a plasma concentration of total GLP-1 was quantified using the Total GLP-1 ELISA (7-36 and 9-36) Assay Kit (Alpco, 43-GPTHU-E01).

Eight-weeks old ICR male mice fasted for at least 16 hours were orally administered with each of compound 1 at 3 mg/kg and voglibose at 0.02 mg/kg as an alpha-glucosidase inhibitor alone or in combination. At a time point of 30 minutes later, sucrose solution was orally loaded at 2 g/kg/10 ml. To evaluate a drug response to postprandial blood glucose levels, a blood glucose in whole blood collected from tail vein at a time point of 0, 15, 30, 60, 90, and 120 minutes after glucose injection in the blood was measured with a Roche's AccuChek Active glucose meter. A time-blood glucose level response curve was obtained. In terms of a rate of change, a comparison was made between an area under the time-blood glucose level curve in a control group administered with solvent only and an area under the time-blood glucose level curve in a drug administration group.
