Embodiments of the present disclosure relate to a pharmaceutical composition including a GPR40 agonist and an SGLT-2 inhibitor, a method of preparing the same, and a method of treating type 2 diabetes mellitus and the like using the same.
Diabetes mellitus is a metabolic disease resulting from impaired or insufficient insulin secretion and characterized by hyperglycemia, that is, an excess of glucose in the blood, and is a progressive debilitating disorder that causes various microvascular and macrovascular complications and morbidities. Type 2 diabetes mellitus, which is the most common type of diabetes mellitus, is characterized by increased insulin resistance associated with inadequate insulin secretion after a period of compensatory hyperinsulinemia.
Free fatty acids (FFAs) have been demonstrated to influence insulin secretion from β-cells by primarily enhancing glucose-stimulated insulin secretion (GSIS). G-protein-coupled receptors (GPCRs) expressed in β-cells are known to regulate release of insulin in response to changing plasma glucose levels.
GPR40, also known as fatty acid receptor 1 (FFAR1), is a membrane-bound FFA receptor that is preferentially expressed in pancreatic islets, especially β-cells thereof, and mediates medium- to long-chain fatty acid-induced insulin secretion. GPR40 is also expressed in enteroendocrine cells. Activation of GPR40 in enteroendocrine cells promotes secretion of intestinal incretin hormones, for example, GLP-1, GIP, CCK, and PYY. GPR40 modulators not only can promote GSIS through an incretin effect, but also hold promise as a potential combination with a wide variety of antidiabetic drugs. Thus, such GPR40 modulators can contribute to reduction of medical burden of patients with type 2 diabetes through enhanced glycemic control.
In view of these advantages, many pharmaceutical companies have worked on developing a GPR40 agonist for the past several years. However, there are still no commercially available GPR40 agonists. An example of a few tangible results is fasiglifam developed by Takeda Pharmaceutical Co., Ltd. of Japan. Fasiglifam is the first GPR40 agonist compound to enter clinical trials and has proven its hypoglycemic efficacy for patients with type 2 diabetes mellitus. However, development of fasiglifam was discontinued due to concerns about drug-induced hepatotoxicity or drug-induced liver injury (DILI)) during phase 3 clinical trials.
Therefore, in modern societies where the number of patients with metabolic syndrome including diabetes is rapidly increasing, there is a growing need to provide an effective treatment for type 2 diabetes patients using a GPR40 agonist having a function of enhancing glucose-dependent insulin secretion.
As a GPR40 agonist, a compound represented by Formula I, a racemate of the compound, an enantiomer of the compound, a diastereomer of the compound, or a pharmaceutically acceptable salt of the compound, the racemate, the enantiomer or the diastereomer is disclosed in Korean Patent Laid-open Publication No. 10-2018-0069718, the disclosure of which is incorporated by reference in its entirety.
Plasma glucose is generally filtered through the renal glomerulus and is actively reabsorbed by the proximal tubule. Sodium-glucose cotransporter 2 (SGLT-2) is considered a major transporter involved in glucose reuptake in the proximal tubule. A selective inhibitor of SGLT-2, which is a sodium-dependent glucose transporter in the kidney, is expected to be able to normalize plasma glucose levels by improving insulin sensitivity and delaying the onset of diabetic complications through enhancement in excretion of glucose in the urine.

Next, the present disclosure will be described in more detail with reference to some examples. However, it should be noted that these examples are provided for illustration only and are not to be construed in any way as limiting the present disclosure.
In this experiment, the compound represented by Formula 1 was prepared by the method described in Example 5 of Korean Patent Laid-Open Publication No. 10-2018-0069718 and dapagliflozin (HY-10450, MedChemExpress Co., Ltd.) was used. As a control group, a vehicle (0.5% carboxymethyl cellulose (CMC)) was used.
After at least 1 week of acclimatization of 8 to 10 week-old male Sprague-Dawley (SD) rats, an oral glucose tolerance test (OGTT) was performed using healthy rats.
After 16 hours of fasting, the rats were randomly divided into groups each having 5 rats similar in body weight and blood glucose level, followed by administration of the vehicle (0.5% carboxymethyl cellulose (CMC)), 0.3 mg/kg of the compound represented by Formula 1 alone, 0.1 mg/kg of dapagliflozin alone, or a combination of 0.3 mg/kg of the compound represented by Formula 1 and 0.1 mg/kg of dapagliflozin. One hour after administration of each of the drugs, glucose (2 g/kg) was intraperitoneally injected at a dose of 10 ml/kg. Blood glucose level was measured 60 minutes before glucose injection and 0, 15, 30, 60, and 120 minutes after glucose injection through puncture of the caudal vein using a blood glucose meter (Gluco DR. Almedicus. Co. Ltd.). Results were expressed by a reduction rate (%) in area under the blood glucose curve (AUC) relative to administration of the vehicle.
Results of measuring AUC from 0 to 60 min and from 0 to 120 min after glucose injection according to the above method are shown in Table 1 and
An experiment was conducted in the same manner as in Example 1 except that 0.3 mg/kg of empagliflozin (HY-15409, MedChemExpress Co., Ltd.) was used instead of 0.1 mg/kg of dapagliflozin. Results are shown in Table 2 and
The results show that combined administration of the compound represented by Formula 1 and the SGLT2 inhibitor (dapagliflozin or empagliflozin) can produce a synergistic effect in reducing blood glucose levels, as compared with administration of the compound represented by Formula 1 alone or administration of dapagliflozin or empagliflozin alone.
