The present invention relates to a GLP-1 receptor agonist having a novel structure.
Diabetes is a metabolic disease which is caused by deficiency of insulin secretion or insulin action, and can be mainly classified into type 1 and type 2 depending on its mechanism. Type 1 diabetes is caused by deficiency of insulin secretion resulting from autoimmune destruction of pancreatic beta cells. Type 2 diabetes, also referred to as insulin-independent diabetes, is mainly caused because the amount of insulin produced according to an increase in blood sugar is not sufficient for cells to absorb glucose and reduce blood sugar levels. Treatment of Type 1 diabetes requires insulin therapy which involves injecting insulin externally, and for type 2 diabetes, a therapeutic agent is administrated alone or in combination, or insulin therapy is used, depending on the disease progression.
Currently known oral diabetes medicines include insulin secretagogues, biguanides, alpha-glucosidase inhibitors, thiazolidinedione, sodium-glucose cotransporter 2 (SGLT-2) selective inhibitors, and the like. Insulin secretagogues are, for example, sulfonylurea (e.g., glipizide, glimepyride, glyburide), meglitinide (e.g., nateglinide, repaglinide) and dipeptidyl peptidase IV (DPP-IV) inhibitors (eg, sitagliptin, vildagliptin, alogliptin, dutogliptin, linagliptin, saxagliptin), and the like. Biguanides are believed to act primarily to reduce the production of glucose in the liver, and the examples thereof include metformin, and the like. Alpha-glucosidase inhibitors reduce the absorption of glucose in the intestine, and the examples thereof include acarbose, and the like. Thiazolidinediones act on a specific receptor (peroxisome proliferatoractivated receptor-gamma) in liver, muscle, and adipose tissue, and the examples thereof include pioglitazone, rosiglitazone, and the like. SGLT-2 inhibitors inhibit glucose reuptake in the kidney, thereby lowering blood glucose levels, and the examples thereof include dapagliflozin, empagliflozin, canagliflozin, ertugliflozin, and the like.
However, besides the positive aspects of maintaining continued normal blood sugar levels, oral diabetes medicines currently used in clinical practice cause various side effects such as hypoglycemia, diarrhea, weight gain, cardiovascular problems, liver toxicity when taken for a long time, or many of them have a limited effect. In addition, insulin administration, which is the last treatment method, is also inconvenient because of having to be subcutaneously injected two or three times a day, and is likely to cause hypoglycemia which is the most serious side effect.
To overcome such problems, glucagon-like peptide-1 (GLP-1) receptor agonists have recently emerged as a next generation diabetes medicine.
GLP-1, a long incretin hormone having 30 amino acids, is secreted by intestinal L-cells in response to ingestion of food. In a healthy individual, GLP-1 plays a significant role in controlling postprandial blood glucose by promoting glucose-dependent insulin secretion in the pancreas. GLP-1 also inhibits glucagon secretion, causing a decrease in hepatic glucose production. In addition, GLP-1 delays gastric emptying, slows small intestine motility, and thus delays food absorption.
GLP-1 receptor agonists, such as GLP-1 and analogs or derivatives thereof, exhibit good potential in clinical trials for the treatment of type 2 diabetes, and induces a number of biological effects such as stimulation of insulin secretion, inhibition of glucagon secretion, inhibition of gastric fasting, inhibition of gastric motility or intestinal motility, and induction of weight loss ((i) Cardiovascular Diabetology 2014, 13:142; (ii) Front. Neurosci. 9:92; (iii) Peptides 100 (2018) 190-201; (iv) World J Hepatol. 2018 Nov. 27; 10(11): 790-794). Further, even when taken for a long time, GLP-1 receptor agonists provide pancreatic protection, have no risk of hypoglycemia, and maintain adequate blood sugar levels for a long time. GLP-1 receptor agonists known to date include liraglutide, albiglutide, exenatide, lixisenatide, dulaglutide, semaglutide, and the like.

The efficacy of the compound according to the present invention as a GLP-1 receptor agonist was determined by measuring cAMP (cyclic Adenosine Monophosphate) activity using a CHO-K1/GLP-1 receptor-expressing cell (Genscript, M00451) that expresses a human GLP-1 receptor.
Specifically, CHO-K1/GLP1 receptor-expressing cells in a Ham's F12 medium containing 10% FBS, 1% NEAA, 200 ug/ml Zeocin, and 100 ug/ml Hygromycin B were dispensed into a 96-well plate (SPL, 30096) at the amount of 30,000 cells/100 uL/well, and incubated in a 37° C., 5% CO2 incubator. The next day, the medium was removed, and a 50 uL of HBSS medium containing 0.1% BSA, 0.5 mM IBMX, and 5 mM HEPES was added to each well. After dissolving a test substance (6.4 nM to 20 uM) of 2× concentration in the HBSS medium containing 0.1% BSA, 0.5 mM IBMX, and 5 mM HEPES, 50 uL of the HBSS medium in which the test substance was dissolved was added to each well, and incubated in a 37° C., 5% CO2 incubator. The cAMP activity was measured according to the manufacturer's instructions using the cAMP dynamic HTRF kit (Cisbio, 62AM4PEC). After incubation, the medium was discarded, and the cells were lysed. cAMP-d2 and anti-cAMP cryptate conjugate were added thereto and reacted for 3 hours. After completion of the reaction, fluorescence was measured with a microplate reader (Molecular Device, Flexstation 3) (excitation wavelength of 313 nm, and emission wavelength of 665 nm and 620 nm). The cAMP activity was shown by fluorescence resonance energy transfer (FRET) which occurs when cAMP-d2 and anti-cAMP-cryptate were in close proximity to each other, and was calculated as a fluorescence ratio of 665 nm/620 nm. Intracellular cAMP competes with cAMP-d2 for anti-cAMP cryptate, and the measured signal of fluorescence resonance energy transfer (FRET) is inversely proportional to intracellular cAMP. The activity of the compounds was calculated based on the degree of change in the FRET signal, and the EC50 of the compounds is shown in Table 1 below.
To measure the hERG (Human ether-a-go-go-related gene) channel inhibition rate of the compound according to the present invention, the following test was performed using a Predictor hERG Fluorescence Polarization assay kit (Invitrogen, PV5365).
Specifically, a test substance was dissolved in DMSO to prepare a 50 mM solution. A 4 mM solution was prepared by diluting the 50 mM solution with DMSO in a U bottom 96-well plate (SPL, 34096), and was then diluted 100-fold with a test buffer to prepare a 40 uM (4×) solution. The positive control E-4031 (3 mM) provided in the kit was diluted 25-fold with a test buffer to prepare a 120 uM solution. 5 uL of the diluted test substance solution was dispensed into a 384-well assay plate (corning, 3677). hERG Membrane (2×) and Tracer (4×) provided in the kit were respectively added at 10 uL and 5 uL, and then subjected to the reaction at room temperature for 2.5 hours. After completion of the reaction, fluorescence polarization (mP) was measured with a Multimode Plate Reader (Perkin-Elmer, Envision) (excitation wavelength of 531 nm, and emission wavelength 579 nm). The value of the percent inhibitory activity (% inhibition) at 10 uM of each test substance was calculated by the following equation, and the results are shown in Table 2:
(% inhibition)=100−{(mP of the compound according to the present invention−E-4031 mP)/(mP of the solvent control−E-4031 mP)}×100
CYP inhibition was tested to confirm the effects of the compounds according to the present invention on liver metabolic enzymes. Corning (459500, 459400, 459100) kits were used for CYP1A2, CYP2C19, and CYP3A4, and Invitrogen (P2861, P2862) kits were used for CYP2C9 and CYP2D6, and the test method basically followed the test methods of each manufacturer.
The test compound was initially prepared by diluting the compound in DMSO (Sigma, 276855) to have a concentration of 50 mM. For Corning products, the test compound (50 mM) was diluted in acetonitrile to have a concentration of 50× of a final concentration (10 uM), and a NADPH-coenzyme mixture and an enzyme-substrate mixture were mixed at a predetermined concentration provided by the kit, according to the type of enzyme. 4 uL of the 50× test compound and 96 uL of the NADPH-coenzyme mixture were mixed in the U-bottom 96-well plate, and then reacted first in a 37° C. incubator for 10 minutes. Next, 100 uL of an enzyme-substrate mixture was added, and reacted in a 37° C. incubator for 15 minutes (CYP1A2) or 30 minutes (CYP2C19, CYP3A4), respectively. At the end of the reaction time, 75 uL of a reaction termination solution (0.5 M Tris base ((HOCH2)3CNH2)) was added to terminate the reaction, the reaction product was transferred to a white plate, and the fluorescence wavelength was read by a microplate reader (Molecular Device, Flexstation 3)(for CYP1A2 and CYP2C19, excitation wavelength 410 nm, emission wavelength of 460 nm; for CYP3A4, excitation wavelength of 409 nm, emission wavelength of 530 nm).
For Invitrogen products, the test compound (50 mM) was diluted in a test buffer to have a concentration of 2.5× of a final concentration (10 uM). The enzyme mixture and the substrate mixture were mixed at a predetermined concentration provided by the kit, according to the type of enzyme. 80 uL of the 2.5× test compound prepared in the U-bottom 96-well plate and 100 uL of the enzyme mixture were mixed, reacted first for 10 minutes. Then, 20 uL of the substrate mixture was added thereto and reacted for 1 hour. After completion of the reaction, the reaction product was transferred to a white plate and the fluorescence wavelength was read by a microplate reader (Molecular Device, Flexstation 3) (for CYP2C9, excitation wavelength of 415 nm, emission wavelength of 460 nm; for CYP2D6, excitation wavelength of 415 nm, emission wavelength of 520 nm). The inhibition rate was calculated as the remaining activity value of the test compound-treated group compared to the solvent control group, using the fluorescence value of the solvent control group as a 100% activity value, as shown in the following equation:
Result value (Remaining Activity; unit %)=(fluorescence value of the test compound/fluorescence value of the solvent control)×100
