Definitions
- the present invention relates to a composition for preventing, improving or treating advanced glycation end products-related diseases, including an indole derivative or a pharmaceutically acceptable salt thereof.
- the composition of the present invention has an effect of trapping methylglyoxal (MGO), a major precursor of advanced glycation end products, and thus can be usefully used for preventing, improving or treating diseases related to advanced glycation end products.
- MGO methylglyoxal
- Diabetes is a metabolic disease in which high blood sugar levels persist for a long period of time due to insufficient secretion of insulin or insulin resistance.
- glycation products invade the retina, kidneys, nerves, or large and small blood vessels throughout the body, resulting in chronic complications.
- diabetes complications are more dangerous than diabetes itself, the biggest goal in diabetes treatment today is to suppress the induction or progression of diabetes complications.
- Representative diabetic complications include diabetic retinopathy, diabetic cataract, diabetic nephropathy, diabetic neuropathy, diabetic heart disease, diabetic osteoporosis, and diabetic atherosclerosis.
- Mechanisms that cause these diabetic complications include oxidative stress caused by free radicals, non-enzymatic glycation of proteins, and osmotic pressure due to changes in the polyol pathway mechanism. Stress is described.
- Oxidative stress which causes complications of diabetes, refers to a reaction that occurs when the removal function of active oxygen generated in the body is lowered or the production of active oxygen is rapidly increased due to environmental factors.
- oxidative stress increases due to hyperglycemia, thereby increasing insulin resistance and causing cell damage such as blood vessels, kidneys, and retina.
- advanced glycation end products (AGEs) generated due to oxidative stress are a major cause of diabetic complications.
- Glycosylation is a non-enzymatic reaction between the aldehyde group of saccharides present in blood or cell fluid and the free amino group of proteins inside and outside cells.
- NASH nonalcoholic steatohepatitis
- FAA free fatty acid
- Non-alcoholic steatohepatitis is often accompanied by type 2 diabetes, another insulin resistance-related disease.
- Methylglyoxal is a major precursor of advanced glycation end products that cause complications from diabetes.
- Experimental results have shown that MGO formation by cell metabolism increases at high glucose concentration in vitro, and abnormal accumulation of MGO affects the occurrence of diabetic complications in various tissues and organs.
- MGO levels induced obesity and hyperglycemia in Drosophila.
- MGO is produced through several pathways, including by-products of glycolysis, and several mechanisms may affect MGO detoxification.
- Increased MGO due to impaired detoxification within the organism has direct toxicity to tissues and leads to the gradual development of obesity, hyperglycemia and insulin resistance. This means that an increase in MGO can cause a potential vicious cycle as a result and cause of insulin resistance and hyperlipidemia (Moraru et al., 2018).
- the generation of advanced glycation end products is suppressed by trapping MGO prior to the formation of advanced glycation end products, the resulting diabetic complications can be prevented.
- obesity and coronary artery disease act as risk factors in type 2 diabetic patients, the treatment of hyperglycemia and these diseases must be performed simultaneously to prevent the progression of complications. MGO accumulation also affects obesity. Capture is also expected to help manage obesity in people with type 2 diabetes.
- the inventors of the present invention completed the present invention by discovering that the indole derivative of the present invention has an excellent MGO trapping ability and has an effect of preventing, improving or treating diseases related to advanced glycation end products.
