Definitions
- the present invention belongs to the field of biomedicine, and specifically relates to a salt, a crystal form, a preparation method and an application of a cycloolefin compound.
- Diabetes mellitus is a common endocrine metabolic disease. It is caused by metabolic disorders due to various reasons, leading to multi-system and multi-organ damage.
- the incidence rate is high. There are about 425 million diabetics in the world. The incidence rate of diabetes in China is about 10%, of which type 2 diabetes accounts for 90%. The incidence rate is still increasing, and the age of patients is getting younger and younger.
- GLP-1 receptor agonists glucagon-like peptide 1 (GLP-1) receptor agonists
- DPP-IV dipeptidyl peptidase
- SGLT-2 sodium-glucose co-transporter 2
- ⁇ -glucosidase inhibitors etc., among which GLP-1 receptor agonists are the most popular.
- GLP-1 is a peptide hormone secreted by human intestinal L cells. Its receptors are distributed in pancreatic islet cells, various gastrointestinal cells, central nervous system and peripheral nervous system neurons. After activation, GLP-1 receptors have physiological effects such as promoting insulin secretion, inhibiting glucagon secretion, suppressing appetite and delaying gastric emptying. Clinical evidence shows that compared with other hypoglycemic drugs, GLP-1 receptor agonists have better blood sugar lowering effects and are less likely to have side effects such as hypoglycemia. In addition, it has additional cardiovascular benefits, and can reduce food intake and delay gastric emptying, which is beneficial for weight control.
- the GLP-1 receptor agonists on the market are all peptide drugs, most of which need to be administered subcutaneously, and patients' compliance is poor.
- the bioavailability of oral peptides is very low. Therefore, there is a great clinical demand for the development of oral small molecule GLP-1 receptor agonists.
- PF-06882961 has shown significant hypoglycemic and weight-reducing effects in early clinical trials, and its safety is similar to that of peptide GLP-1 receptor agonists. It is expected to bring more treatment options for patients with diabetes, obesity, and NASH in the future.
- GLP-1 receptor agonists There is a huge clinical demand for GLP-1 receptor agonists. Oral small molecule GLP-1 receptor agonists with lower cost and better compliance have the potential to treat a variety of metabolic diseases and have broad market prospects.
