Description

FXR SMALL MOLECULE AGONIST AND PREPARATION METHOD THEREFOR ANDUSETHEREOF
Technical field The present invention relates to the field of medicine, and relates to a class of compounds as FXR agonist and preparation therefor and use thereof. Specifically, it relates to a class of non-steroidal compounds that can be used as FXR agonist and the enantiomer, diastereomer, tautomer, solvate, prodrug, or pharmaceutically acceptable salt thereof, the preparation method therefor and use thereof in the manufacture of a medicament for the treatment of FXR-related disease.
Background technique Nuclear receptors are widely present in organisms and are a type of nuclear transcription regulators that rely on specific ligand activation. Metabolic nuclear receptors are a type of nuclear receptors that regulate substance metabolism, cell proliferation, and apoptosis in the body. Farnesoid X receptor (FXR) is a member of the nuclear receptor superfamily, which was first discovered by Foman et al. in 1995 and named because its transcriptional activity can be enhanced by farnesoid. The FXR structure contains ligand-independent transcription activation function domain (AF1) at amino-terminal, DNA binding domain (DBD), hinge region, ligand binding domain (LBD) and ligand-dependent transcription activation function domain (AF2) at carbon terminal, which is a typical nuclear receptor structure. FXR is activated by bile acids in the body and participates in the processes of bile acid metabolism, lipid metabolism, and sugar metabolism in the living body. The mechanism by which FXR regulates bile acid metabolism and transport is mainly accomplished by regulating the transcription of cholesterol 7a hydroxylase (CYP7A1) which is a rate-limiting enzyme of bile acid synthesis. Although FXR cannot directly act on the CYP7Al promoter, it can induce the expression of small heterodimer partner (SHP) and combine HNF-4a (hepatocyte nuclear factor 4a) and LRH-1 (liver receptor homolog) to down-regulate the transcription of CYP7A1. In the process of lipid metabolism, FXR in the liver regulates lipid metabolism and transport to reduce plasma free fatty acids and triglycerides by directly or indirectly regulating PPARa, VLDL receptor (very low density lipoprotein receptor, VLDLR), proprotein convertase subtilisin kexin type 9 (PCSK9), scavenger receptor group B type 1 (SRB1), phosphor lipid transfer protein (PLTP), liver X receptor (LXR), sterol regulatory element-binding protein-IC (SREBP-1C) and fatty acid synthetase (FAS), and activating lipoprotein lipase (LPL) and the like. In the process of glucose metabolism, the activation of FXR can promote liver glycogen synthesis and increase insulin sensitivity and insulin secretion to control blood glucose levels in the body. Since FXR plays an important role in the processes of bile acid metabolism, lipid metabolism and glucose metabolism, FXR ligand small molecule compounds are expected to be used as new medicament for the treatment of hypertriglyceridemia, type 2 diabetes, metabolic syndrome, NAFLD and other metabolic-related diseases.
Summary of the invention The present invention seeks to provide a FXR small molecule agonist and preparation method therefor and use thereof.
In the first aspect of the present invention, it provides a compound represented by general formula I, or enantiomer, diastereomer, tautomer, racemate, solvate, prodrug or pharmaceutically acceptable salt thereof,

The reaction in this method was carried out in a 384 well plate, and the total reaction volume was 15 pL. The mixture of protein, agonist, co regulatory factor, AlphaScreen@ acceptor beads and AlphaScreen@ donor beads was reacted in abuffer containing Tris-HCl50 mM (pH7.4),50 mMNaCl, BSA 0.1%, and1mM DTT. The FXR activity was reflected by the fluorescence signal intensity at 570nm wavelength detected by the Envision fluorescence detector. The value of EC50 was calculated by the software Graphpad Prism 5. Test method for FXR activity at the cell level The FXR expression plasmid and FXRE luciferase reporter plasmid at a ratio of 1:9 was co-transfected into 293T cells, and then the transfected cells were seeded on a 96-well flat bottom microplate (ViewPlate-96, White 96- well Microplate with Clear Bottom, PerkinElmer) at 5x10 5/well. The cells were cultured for 24 hours to ensure plasmid expression. Then the FXR receptor agonist to be tested was added and acted for 18 hours. The fluorescence intensity was detected using luciferase kit (steady-Glo Luciferase Assay system) to reflect the compound's activation efficiency on the FXR receptor. CH

Conclusion: The test results show that the compounds of the present invention have good agonistic ability to FXR at the molecular level and the cell level, and the activities of several compounds are significantly better than those of the two positive controls. In vivo pharmacological activity test of liver fibrosis 1) Pharmacodynamic evaluation of compound 1 (LXF-32) on TAA-induced hepatic fibrosis model rats In this experiment, TAA induced hepatic fibrosis model rats were used to investigate the effect of long-term oral administration of compound 1 on hepatic fibrosis in the model rats. Experimental method: Male SD rats were intraperitoneally injected with thioacetamide (TAA, dissolved in normal saline) at a dose of 150 mg/kg three times a week to induce a liver fibrosis model. Four weeks after the model was made, the blood was taken from the retro ocular venous plexus of the rats to detect serum ALP indicators. According to indicators such as ALP and body weight, the rats were randomly divided into 3 groups, each with 8 rats, which were respectively the model control group (Vehicle), Compound 1 group (20 mg/kg), positive compound OCA group (20 mg/kg), etc., orally administered by gavage, once a day. During the administration period, the animal's food intake and body weight were monitored. After 2 weeks of administration, the blood was taken from the retro-ocular venous plexus of the rats to detect serum ALP indicators. After 4 weeks of administration, the blood was taken from the retro-ocular venous plexus and the rats were dislocated and sacrificed. The livers were taken out and weighed. Part of the liver was fixed with 4% paraformaldehyde, and part of the liver was frozen at -80°C. During the whole experiment, another 8 rats in the same cage were injected intraperitoneally with the same volume of normal saline as the system normal control group (WT). This experiment detected indicators such as the level of liver function index ALP in serum, the expression of a-SMA and Collal (fibrosis-related genes) gene level in the liver, the content of hydroxyproline (a characteristic amino acid of collagen) in the liver, and the pathological changes of the liver (Sirius scarlet stain), etc., thereby reflecting whether the compound has the effect of relieving liver fibrosis. The research results showed that the compound 1 of the present invention significantly reduced the level of ALP in serum, reduced the content of hydroxyproline in liver tissue, and significantly down-regulated the expression of a-SMA and Collal mRNA in liver tissue after 4 weeks of administration (Figure 1). In the quantitative analysis of liver pathological sections stained with Sirius Scarlet, compound 1 reduced the collagen content in the liver, because there were large differences within the model group, and there was no statistical difference (Figure 2). In summary, long-term administration of compound 1 (LXF-32) of the present invention could significantly improve the liver function of TAA-induced hepatic fibrosis rats, down regulate the expression of a-SMA and Collal mRNA, reduce the deposition of collagen in the liver, and have a certain alleviating effect on liver fibrosis. 2) Pharmacodynamic evaluation of compound 8 (LXF-116) on CCL4-induced hepatic fibrosis model mice In this experiment, CCL4 induced hepatic fibrosis model mice were used to investigate the effect of long-term oral administration of compound 8 on hepatic fibrosis in the model mice. Experimental method: Male C57BL/6j mice were injected intraperitoneally with 2 mL/kg, 10% CCl4 (dissolved in olive oil) three times a week to induce liver fibrosis model. Two weeks after the model was made, the blood was taken from the retro-ocular venous plexus of the mice to detect serum ALT, AST, TBA and LDH indicators. According to ALT, AST, TBA, LDH, body weight and other indicators, the mice were randomly divided into 5 groups. There are 10 animals in each group, namely the model control group (Vehicle), low-dose compound 8 group (6 mg/kg), high-dose compound 8 group (20 mg/kg), low-dose positive compound OCA group (6 mg/kg), high-dose OCA group (20 mg/kg), etc., orally administered by gavage, once a day. During the administration period, the animals' food intake and body weight were monitored. After 3 weeks of administration, the blood was taken from the retro-ocular venous plexus of the mice to detect serum ALT, AST, TBA and LDH indicators. After 6 weeks of administration, the blood was taken from the retro-ocular venous plexus and the mice were dislocated and sacrificed. The livers were taken out and weighed. Part of the liver was fixed with 4% paraformaldehyde, and part of the liver was frozen at -80°C. During the whole experiment, another 10 mice in the same cage were intraperitoneally injected with the same volume of olive oil as the system normal control group (WT). This experiment detected indicators such as the levels of liver function indicators ALT, AST, TBA, LDH in serum, the expression of a-SMA and Collal gene levels in the liver, and the pathological changes of the liver (Sirius scarlet stain), etc., thereby reflecting whether the compound has the effect of relieving liver fibrosis.
The research results showed that the high-dose compound 8 group and low-dose compound 8 group of the present invention significantly reduced the levels of ALT, AST and TBA in serum after 6 weeks of administration, and had little effect on LDH; the high dose positive compound OCA group significantly reduced the levels of ALT, AST and TBA in serum and the low-dose group only had a lowering effect on TBA; the low-dose compound 8 group had a slightly better effect than the low-dose OCA group (Figure 3). The high-dose compound 8 group significantly down-regulated the expression of a-SMA in the liver, and down-regulated the expression of collal in the liver (Figure 4); in the quantitative analysis of liver pathological sections stained with Sirius scarlet, both the high-dose compound 8 group and low-dose compound 8 group significantly reduced the collagen content in the liver, and the effect of low-dose compound 8 group was slightly better than that of the low-dose OCA group (Figure 5). In summary, long-term administration of compound 8 (LXF-116) of the present invention could significantly improve the liver function of CCl4-induced hepatic fibrosis mice, down regulate the expression of a-SMA and Collal mRNA, reduce the deposition of collagen in the liver, and hava a certain alleviating effect on liver fibrosis
