Description
FIVE-MEMBERED RING DERIVATIVE AND MEDICAL USE THEREOF
Technical Field [0001] The present invention relates to a compound represented by general formula (I) or a stereoisomer, tautomer, deuterated substance, solvate, prodrug, metabolite, pharmaceutically acceptable salt or co-crystal thereof, an intermediate thereof, and a preparation method therefor, as well as an application in the preparation of a drug for treating diabetes.

Technical Field [0001] The present invention relates to a compound represented by general formula (I) or a stereoisomer, tautomer, deuterated substance, solvate, prodrug, metabolite, pharmaceutically acceptable salt or co-crystal thereof, an intermediate thereof, and a preparation method therefor, as well as an application in the preparation of a drug for treating diabetes.
Background Art
[0002] Diabetes is a group of metabolic diseases characterized by hyperglycemia.
Hyperglycemia is caused by defective insulin secretion or impaired insulin biological action, or both. The long-term high blood sugar in diabetes leads to chronic damage and dysfunction of various tissues, especially eyes, kidneys, heart, blood vessels, and nerves.
Diabetes is mainly divided into two types. Type 1 diabetes: destruction of islet B cells leads to absolute insulin deficiency. Type 2 diabetes: insulin resistance is dominant with insulin relative deficiency or impaired insulin secretion is dominant with insulin resistance.
Hyperglycemia is caused by defective insulin secretion or impaired insulin biological action, or both. The long-term high blood sugar in diabetes leads to chronic damage and dysfunction of various tissues, especially eyes, kidneys, heart, blood vessels, and nerves.
Diabetes is mainly divided into two types. Type 1 diabetes: destruction of islet B cells leads to absolute insulin deficiency. Type 2 diabetes: insulin resistance is dominant with insulin relative deficiency or impaired insulin secretion is dominant with insulin resistance.
[0003] Drugs for type 2 diabetes can be divided into six major classes (insulin, insulin secretagogues, biguanides, glucosidase inhibitors, thiazolidinediones, SGLT2 inhibitors), each of which works through a different primary mechanism. However, with the exception of GLP-1 receptor agonists and SGLT2 inhibitors, these drugs have limited efficacy and cannot address the most important problems, namely decreased cellular function and associated obesity.
[0004] GLP-1 is a 30-amino acid long intestinal insulin stimulating hormone secreted by L cells in the intestine. GLP-1 stimulates insulin secretion, reduces glucagon secretion, inhibits gastric emptying, reduces appetite, and stimulates 13-cell proliferation in a physiological and glucose-dependent manner. In nonclinical experiments, GLP-1 promotes the sustainability of 13 cells by stimulating the transcription of genes important for glucose-dependent insulin secretion and by promoting (3 cell regeneration. In healthy individuals, GLP- 1 plays an important role in the regulation of postprandial blood, leading to increased peripheral glucose uptake by stimulating glucose-dependent insulin secretion from the pancreas. GLP-1 also inhibits glucagon secretion, resulting in decreased hepatic glucose output. In addition, GLP-1 delays gastric emptying, slows small bowel motility, and delays food absorption.
[0005] GLP-1 receptor agonists, such as GLP-1, liraglutide and exendin-4, are polypeptide drugs and are mostly used for injection. Small molecule GLP-1 receptor agonists have become a hot spot in drug development in recent years due to their high oral bi availability potential.
Summary of the Invention
Summary of the Invention
[0006] The object of the present invention is to provide a compound capable of stimulating a GLP-1 receptor or a stereoisomer, tautomer, deuterated substance, solvate, prodrug, metabolite, pharmaceutically acceptable salt or co-crystal thereof, and an intermediate and a preparation method thereof, as well as an application in the preparation of a drug for treating diabetes.
[0007] The compound of the present invention has good activity of stimulating a GLP-1 receptor, good pharmacokinetic performance and bioavailability, oral performance and good safety.
[0008] The present invention provides a compound or a stereoisomer, tautomer, deuterated substance, solvate, prodrug, metabolite, pharmaceutically acceptable salt or co-crystal thereof, and the compound is selected from a compound represented by general formula (I), wherein, R2 R2 iR1 DI ______________________________ Le /

[0548] 2. Effects of the compounds on hERG potassium channels [0549] Experimental platform: electrophysiological manual patch-clamp system 1105501 Cell line: Chinese hamster ovary (CHO) cells stably expressing hERG
potassium ion channel [0551] Experimental method: For CHO (Chinese Hamster Ovary) cells stably expressing hERG potassium channel, whole cell patch-clamp technique was used to recorded hERG potassium channel current at room temperature in this experiment. The glass microelectrode is made of a glass electrode blank (BF150-86-10, Sutter) by a puller.
The tip resistance after filling the liquid in the electrode is about 2-5 MEI
The glass microelectrode can be connected to the patch-clamp amplifier by inserting the glass microelectrode into an amplifier probe. The clamping voltage and data recording are controlled and recorded by the pClamp 10 software through a computer. The sampling frequency is 10 kHz, and the filtering frequency is 2 kHz. After the whole cell records were obtained, the cells were clamped at -80 mV, and the step voltage that induced the hERG potassium current (/ hERG) was depolarized from -80 mV to +20 mV for 2 s, then repolarized to -50 mV, and returned to -80 mV after 1 s. This voltage stimulation was given every 10 s, and the administration process was started after the hERG
potassium current was confirmed to be stable (at least 1 minute). The compound was administered for at least 1 minute at each test concentration, and at least 2 cells (n>2) were tested at each concentration.
[0552] Data processing:
[0553] Data analysis processing was carried out by using pClamp 10, GraphPad Prism 5 and Excel software. The inhibition degree of hERG potassium current (peak value of hERG tail current induced at -50 mV) at different compound concentrations was calculated by the following formula: Inhibition % = [1 ¨ (///o)]x100%.
[0554] Among the formula, Inhibition % represents the percentage of inhibition of hERG potassium current by the compound, and / and /o represent the amplitude of hERG
potassium current after and before dosing, respectively.
[0555] Compound IC50 was calculated using GraphPad Prism 5 software by fitting according to the following equation:
[0556] Y = Bottom + (Top-Bottom)/(1+10^((LogIC50-X) x HillSlope)) [0557] Among the equation, X represents the Log value of the tested concentration of the test sample, Y represents the inhibition percentage at the corresponding concentration, and Bottom and Top represent the minimum and maximum inhibition percentage, respectively.

[0548] 2. Effects of the compounds on hERG potassium channels [0549] Experimental platform: electrophysiological manual patch-clamp system 1105501 Cell line: Chinese hamster ovary (CHO) cells stably expressing hERG
potassium ion channel [0551] Experimental method: For CHO (Chinese Hamster Ovary) cells stably expressing hERG potassium channel, whole cell patch-clamp technique was used to recorded hERG potassium channel current at room temperature in this experiment. The glass microelectrode is made of a glass electrode blank (BF150-86-10, Sutter) by a puller.
The tip resistance after filling the liquid in the electrode is about 2-5 MEI
The glass microelectrode can be connected to the patch-clamp amplifier by inserting the glass microelectrode into an amplifier probe. The clamping voltage and data recording are controlled and recorded by the pClamp 10 software through a computer. The sampling frequency is 10 kHz, and the filtering frequency is 2 kHz. After the whole cell records were obtained, the cells were clamped at -80 mV, and the step voltage that induced the hERG potassium current (/ hERG) was depolarized from -80 mV to +20 mV for 2 s, then repolarized to -50 mV, and returned to -80 mV after 1 s. This voltage stimulation was given every 10 s, and the administration process was started after the hERG
potassium current was confirmed to be stable (at least 1 minute). The compound was administered for at least 1 minute at each test concentration, and at least 2 cells (n>2) were tested at each concentration.
[0552] Data processing:
[0553] Data analysis processing was carried out by using pClamp 10, GraphPad Prism 5 and Excel software. The inhibition degree of hERG potassium current (peak value of hERG tail current induced at -50 mV) at different compound concentrations was calculated by the following formula: Inhibition % = [1 ¨ (///o)]x100%.
[0554] Among the formula, Inhibition % represents the percentage of inhibition of hERG potassium current by the compound, and / and /o represent the amplitude of hERG
potassium current after and before dosing, respectively.
[0555] Compound IC50 was calculated using GraphPad Prism 5 software by fitting according to the following equation:
[0556] Y = Bottom + (Top-Bottom)/(1+10^((LogIC50-X) x HillSlope)) [0557] Among the equation, X represents the Log value of the tested concentration of the test sample, Y represents the inhibition percentage at the corresponding concentration, and Bottom and Top represent the minimum and maximum inhibition percentage, respectively.
