Abstract
Description
[Technical Field]
[0001] The present disclosure relates to the pharmaceutical field, and to fused imidazole derivatives, their preparation methods, and pharmaceutical applications. In particular, the present disclosure relates to fused imidazole derivatives represented by general formula (I), their preparation methods, pharmaceutical compositions containing the derivatives, and their use in the field of diabetes treatment as GLP-1 receptor agonists. [Background technology]
[0002] Diabetes mellitus (DDM) is a multifactorial metabolic disease characterized by chronic hyperglycemia accompanied by abnormalities in glucose, lipid, and protein metabolism due to defective insulin secretion or action. Diabetes is an ancient disease caused by an absolute or relative deficiency of insulin in the body, which leads to elevated blood glucose levels, resulting in the excretion of large amounts of glucose in the urine and resulting in symptoms such as polydipsia, polyuria, polyphagia, and weight loss.
[0003] Generally, there are two types of diabetes. Patients with type 1 diabetes, or insulin-dependent diabetes, produce very little or no insulin themselves. Insulin is the hormone that regulates the body's use of glucose. Patients with type 2 diabetes, or non-insulin-dependent diabetes, have plasma insulin levels equal to or higher than those of non-diabetic patients. However, these patients are resistant to insulin, which promotes glucose and lipid metabolism in key insulin-sensitive tissue cells, such as muscle, liver, and adipose tissue. Even high plasma insulin levels cannot overcome the patients' significant insulin resistance.
[0004] Insulin resistance is caused not only by a decrease in the number of insulin receptors but also by defects in insulin receptors, but the underlying mechanism remains unclear. Due to insulin response resistance, insulin is unable to activate glucose uptake, oxidation, and storage in muscle tissue, and is unable to effectively suppress lipolysis in adipose tissue and glucose production and secretion in the liver.
[0005] Glucagon-like peptide 1 (GLP-1) is an incretin hormone secreted by L-cells in the lower gastrointestinal tract.
[0006] GLP-1 exerts its effects by binding to specific receptors that are widely distributed. Currently, GLP-1 receptors have been identified in pancreatic islets, gastrointestinal tract, lungs, brain, kidneys, hypothalamus, and cardiovascular system, and may also be present in liver, adipose tissue, and skeletal muscle. GLP-1 not only stimulates insulin secretion by acting on β cells, but also inhibits glucagon secretion by acting on α cells. Serum GLP-1 levels generally do not differ significantly between patients with normal glucose tolerance, impaired glucose tolerance, and type 2 diabetes. However, after a meal, β cells exhibit a defective response to GLP-1, and under certain conditions, this response is significantly enhanced after continuous infusion of GLP-1. The extremely short duration of action of the human body's own GLP-1 (t1 / 2 < 1.5 minutes after intravenous injection) makes it unsuitable for clinical diabetes treatment.
[0007] Peptide GLP-1 receptor agonists (e.g., liraglutide, exenatide, etc.) have the effect of improving blood glucose levels in patients with type 2 diabetes by reducing fasting and postprandial glucose. However, because peptide GLP-1 has low oral bioavailability and is inconvenient to administer, there is great demand for small molecule GLP-1 receptor agonists with good oral bioavailability.
[0008] Patent applications that disclose GLP-1 receptor small molecule agonists include WO2009111700, WO2010114824, WO2018109607, WO2019239319, and WO2018056453, among others. Summary of the Invention
