- the present invention relates to glycosylated exenatide analogs and uses thereof.
- the present invention relates to exenatide dimer analogs and uses thereof.
- Glycosylation a process by which sugars are attached to proteins expressed in vivo, is a reaction that occurs in the Golgi apparatus, an organelle in cells, and glycoproteins formed by glycosylation are related to intercellular bonding, tissue development, immune response, and hormone action. It is known to be involved in various biological phenomena. Studies on the structure of sugar began in 1880, and studies on sugar and glycosylation have been actively conducted until now. Recently, research on drug development using glycosylation technology is in progress.
- Exenatide is a functional analog of GLP-1 (Glucagon-like Peptide-1) isolated from the salivary glands of Heloderma suspectum in the southeastern United States, and is used as a peptide treatment for type 2 diabetes. . Recently, the development of persistent functional analogs with improved stability in the body of GLP-1 analogs including exenatide has been actively made.
- GLP-1 Glucagon-like Peptide-1
- Exenatide whose scientific name is'Exendin-4', is a biologically active peptide composed of 39 amino acids. It is present in humans, but has 53% amino acid similarity to GLP-1 and is resistant to degrading enzymes such as DPP-4 (Dipetidyl peptidase-4). It is stable and has a relatively long half-life in the body compared to GLP-1.
- Exenatide is administered twice a day, before breakfast and dinner. Because exenatide is excreted by the kidneys, it is not recommended for use in patients with severe renal impairment or end-stage renal disease.
- Exenatide excretion is not dependent on liver function and therefore does not interact with drugs metabolized to the liver.
- exenatide can interact with other drugs related to absorption because it affects gastric motility.
- exenatide has been reported to have side effects such as a decrease in drug efficacy due to an immune response in the body. Therefore, the development of a peptide drug using the glycosylation process occurring in the body is expected to show improved stability in the body and improved immunogenicity.
- Exenatide is an agonist of GLP-1R (glucagon-like peptide-1 receptor) and is used as a peptide treatment for type 2 diabetes. Recently, exenatide and other side effects such as hypoglycemia and stability in the body of GLP-1 analogs The development of this improved, sustained-acting analog is actively underway.
- GLP-1R glucagon-like peptide-1 receptor
- GLP-1R and GCGR glucagon receptor bind to GLP-1 and glucagon in the body, respectively, and play an important role in maintaining homeostasis in the body by regulating blood sugar. It is known that GLP-1R is activated in the cerebral cortex and intestines to inhibit appetite and at the same time reduce intestinal motility to play an important role in weight loss.
- GCGR is known to contribute to weight loss by decomposing accumulated fat through increased activity of HSL and ATGL, which are lipolytic enzymes in white adipose tissue, and heat energy generation in brown adipose tissue (REFERENCE), type 2 diabetes.

- blood glucose was measured using a blood glucose meter (acu-check, Roche, Germany) using blood extracted from the tail vein of the mouse at 0, 15, 30, 45, 60, 90, and 120 minutes, and the result was It is shown in FIGS. 11A to 11B and Table 12.
- Increased fat accumulation in the body due to obesity increases fat toxicity to beta cells of the pancreatic islet that produces insulin, thereby reducing insulin production and inhibiting insulin consumption in liver and muscle, tissues that absorb and store the increased blood sugar after eating. Therefore, it is reported as the main cause of the increase in insulin resistance, which is the main cause of hyperglycemia symptoms by inducing hyperinsulinemia and decreased insulin function.
- Insulin resistance experiment was conducted in a period corresponding to 8 weeks to confirm the insulin sensitivity according to long-term administration of the drug, and after the long-term administration experiment was completed.
- Mouse blood was collected and the insulin concentration in the blood was analyzed through mouse insulin ELISA to determine whether or not insulin resistance was improved.
- each analogue was administered subcutaneously at a concentration of 1 nmol/kg, and after 30 minutes, insulin (1 unit/kg) was administered intraperitoneally. After 0, 15, 30, 60, 90, 120 minutes elapsed, blood was collected from the tail of the mouse, and the blood glucose was measured with a blood glucose meter (acc-check, Roche, Germany) to analyze the sensitivity to insulin, and the result It is shown in Figures 12a to 12b and Tables 13 and 14.
- the incidence of overweight and obesity caused by ingestion of a high fat diet is known to increase the incidence of non-alcoholic fatty liver disease, a metabolic disease, by increasing fat accumulation in the liver, metabolic tissue, and lipid synthesis in hepatocytes.
- non-alcoholic fatty liver disease a metabolic disease
- the amount of lipids in liver tissue was analyzed through Oil red O staining, a lipid identification staining method.
- liver tissue was degraded to confirm the amount of triglyceride, which is a form of lipid storage in cells.
- mice livers were removed, separated by lobes, some were fixed in 4% formaldehyde, and then a paraffin block was prepared and sliced. After dyeing by treatment with Oil red O, a dyeing reagent, it was observed through a microscope. To measure the amount of triglyceride in liver tissue, the separated liver tissue was digested with a 70 um cell strainer, and then the supernatant containing triglyceride obtained by centrifugation at 14,000 rpm was diluted at a certain ratio and analyzed using Triglyceride ELISA. The results are shown in FIGS. 13A to 13B.
- the blood glucose control hormone insulin and the diet control hormone leptin are higher than normal due to tissue resistance to each hormone when type 2 diabetes and obesity occur. These symptoms are called hyperinsulinemia and hyperleptinemia, respectively, and metabolic disease diagnosis It is used as a mark of.
- mice blood was collected after the experiment and ELISA corresponding to each factor to be confirmed The amount of metabolic factors involved in blood was analyzed through the test, and the results are shown in Table 13.
- AGM-212-3 was administered subcutaneously to 16-week-old obese mice (Diet induced obese C57BL/6) once a day for 5 weeks, followed by heat energy generation, exercise, respiration coefficient, and rectal temperature. was measured.
- mice that have been administered for a long time for 5 weeks are reared for 24 hours in a metabolic cage connected to an energy metabolism analyzer, an indirect calorimetry system, and the amount of oxygen consumed through respiration and the amount of carbon dioxide released are measured at 1 hour intervals.
- the Respiratory quotient an index that can confirm the amount of heat energy generated and the preference of nutrients consumed in the body, was analyzed.
- the mouse was taken out of the metabolic feedlot, and a thermal probe was inserted through the anus to measure the rectal temperature, and the results are shown in FIGS. 14A to 14B.
- the brown adipose tissue of the mouse was isolated after a 5-week long-term administration experiment, followed by Western blotting and quantitative real-time polymerase. Chain reaction, qRT-PCR) was used to analyze the expression levels of UCP1, PRDM16, and CIDEA, which are the main factors of the mechanism of heat energy generation.
- the brown adipose tissue fixed in 4% paraformaldehyde was treated with an antibody having specific affinity to UCP1 to observe the expression level of UCP1 in brown adipose tissue, and the results are shown in FIGS. 15A to 15B.
- AGM-212-3 activates glucagon receptors in brown adipose tissue, thereby increasing the generation of a signaling pathway that regulates the expression of factors involved in the generation of thermal energy.
- FIGS. 16A to 16E it was confirmed through Western blot that protein kinase A, an important factor for the transduction of adipose decomposition signal, and HSL, a lipolytic enzyme, were significantly increased in the testicular white adipose tissue of the test group mice. I did.
- Skeletal muscle is the main cause of the basal metabolic rate, and it is reported that it plays an important role in weight control by increasing the generation of heat energy through the same mechanism as brown fat.
- the degree of phosphorylation of AMPK which is a major signal transducer of the C2C12 cell heat energy generation signal transduction pathway through Western blot, decreases compared to the control when the fatty acid palmitic acid (0.75 mM) is treated.
- the degree of phosphorylation of AMPK significantly increased in a concentration-dependent manner when the analogs were treated at different concentrations (10nM, 20nM, 50nM, 100nM).
- FAS lipid synthesis signal transduction factor
- AGM-212-3 like brown fat, increases the generation of heat energy in skeletal muscle, can inhibit lipid synthesis, and has a valuable weight loss ability.
