The present invention belongs to the field of biomedicine, and specifically relates to an aromatic ring-containing biological antagonist, and a preparation method therefor and the application thereof.
Focal segmental glomerulosclerosis (FSGS) is one of the manifestations of nephrotic syndrome and the main cause of end-stage kidney disease. Its pathogenesis is complex and has not yet been fully understood. Current drug treatments, mainly glucocorticoids and immunosuppressants, have poor responses, cannot ideally control the occurrence and progression of FSGS, and have obvious side effects. There is currently no approved treatment for FSGS. The complete response rate of FSGS treatment is less than 30%. One-third of patients progress to chronic renal failure after five years and require long-term dialysis or kidney transplantation to maintain life, which brings heavy economic burden to families and society, and exploring new treatment options has become a focus.
In addition to FSGS, other kidney diseases or conditions characterized by glomerular damage include IgA nephropathy and idiopathic membranous nephropathy. IgA nephropathy, also called Berger's disease, is caused by the accumulation of immunoglobulin A (IgA) in the kidneys. The presence of IgA in the kidney may lead to inflammation, damage to the glomeruli of the kidney, and impaired kidney function, including proteinuria. In some cases, people with IgA nephropathy progress to ESRD. IgA nephropathy is the most common form of glomerulonephritis in the world. In approximately 30% of patients, a decrease in glomerular filtration rate of approximately 50% over 10 years is observed. Patients with IgA nephropathy develop IgG autoantibodies against galactose-deficient IgA1 antibodies. This results in the deposition of these antibodies in the mesangium and activation of complement. Basic treatment for patients with IgA nephropathy involves eliminating risk factors, particularly hypertension, by blocking the renin-angiotensin-aldosterone system (RAAS). Immunosuppression has also been studied in various studies, but no clear advantage was observed. Common side effects of hormone therapy include increased blood sugar, osteoporosis, infection, etc. Therefore, there remains a need for compositions and methods for treating various kidney diseases or conditions, such as FSGS, IgA nephropathy, and IMN.
The endogenous vasoactive peptide angiotensin II (AngII) and endothelin-1 (ET-1) are two powerful vasoconstrictors and are thought to play a role in the control of vascular tone and pathological tissue remodeling associated with a variety of diseases, including diabetic nephropathy, heart failure, and chronic or persistently elevated blood pressure. The renin-angiotensin-aldosterone system (RAAS) regulates blood pressure, fluid and sodium balance. Excessive activation of RAAS can promote systemic and regional glomerular capillary hypertension, cause glomerular hemodynamic damage, and lead to kidney damage and kidney fibrosis via profibrotic and proinflammatory pathways. Drugs for RAAS system such as angiotensin receptor blockers (ARBs) have been used to treat diabetic nephropathy, heart failure, and chronic or persistently elevated blood pressure. In addition, accumulating data demonstrate the potential therapeutic benefits of ETA receptor antagonists (ERAs) in hypertension and diabetic nephropathy.
Studies have shown that the combination of ARB and ERA produces a synergistic effect, with AngII and ET-1 working together in blood pressure control and pathological tissue remodeling. Increased Ang II levels promote ET-1 synthesis and vasoconstriction. Blocking ET receptors with ETA can reduce AngII-induced vasoconstriction and reduce plasma aldosterone. ARB not only blocks the effect of AngII on its AT1 receptor, but also limits the production of ET-1. Therefore, blocking AngII and ET-1 activity simultaneously may provide better efficacy than blocking either substance alone. In addition, although ARB is the standard treatment for patients with diabetic nephropathy, dual antagonists (ARB and ERA) have been reported in phase II clinical development to improve proteinuria changes in patients with FSGS. Therefore, drugs with AT1/ETA dual-target antagonistic mechanism have the potential to treat kidney diseases and are of great significance for drug development.
International application WO 2018071784 reports that Sparsentan, an AT1/ETA dual-target antagonist developed by Retrophin, has good anti-glomerular fibrosis effects in preclinical studies, and has been proven in clinical phase II to improve proteinuria levels in FSGS patients, and Phase III clinical trial is launched for the treatment of FSGS and IgA nephropathy. This project aims to develop an AT1/ETA dual-target antagonist to better treat nephrotic syndrome (including FSGS, IgA nephropathy, diabetic nephropathy, etc.).

Antagonistic effect of test compounds on HEK293-AT1 cell activity
FLIPR Tetra was used to read and collect the fluorescence signal value (RFU). The maximum RFU value was used to calculate the percent activation data based on the readings of the Low control (DMSO control) and High control (100 nM positive compound) experimental groups {% activation rate=(RFUsample−RFUlow control)/(RFUhigh control−RFUlow control)×100}. The concentration of the test compound was 11 concentrations after diluting the reaction system 3 times, ranging from 10 uM to 0.17 nM. XLFit was used to fit the percentage activation rate and 11-point concentration data to a parametric nonlinear logic formula to calculate the IC50 value of the compound.

The main pharmacokinetic parameters were calculated using WinNonlin 6.1. The results of pharmacokinetic experiments in rats are shown in Table 3 below:
The data in the table show that in the rat pharmacokinetic evaluation experiment, the example compounds of the present invention show high exposure after oral administration.
The purpose of this experiment was to detect the stability of the example compounds in liver microsomes of rats, dogs and humans.
Dilution was performed with 100 mM phosphate buffer to a final concentration of 0.625 mg/mL.
NADPH (reduced nicotinamide adenine dinucleotide phosphate) and UDPGA (uridine diphosphate glucuronic acid) were weighed, 100 mM phosphate buffer was added, and the final concentration was 20 mM.
1 mg of Alamethicin was weighed, and 200 μL of DMSO was added to formulate a 5 mg/mL solution. Then dilution was performed with phosphate buffer to a final concentration of 50 μg/mL.
Stop solution: the stop solution contains 100 ng/mL labetalol hydrochloride and 400 ng/mL tolbutamide and cold acetonitrile as internal standard.
400 μL of formulated liver microsomes, 25 μL of compound working solution and 25 μL of Alamethicin were added in sequence to the 96-well plate, and pre-incubated at 37° C. for 10 min. Then 50 μL of formulated NADPH/UDPGA was added to start the reaction and the mixture was incubated at 37° C. The total volume of the reaction system was 500 μL. The final contents of each component are as follows:
The above data show that the example compounds of the present invention have good metabolism stability in liver microsomes of rats, dogs and humans.
Human liver microsome incubation system was used, and the single point method was used to quickly predict the inhibition on CYP450 enzyme subtypes (1A2, 2C19, 2D6, 3A4-M, and 3A4-T) by compounds.
For 2.5 mM NADPH, 4.165 mg of NADPH (reduced nicotinamide adenine dinucleotide phosphate) was weighed and 100 mM phosphate buffer was added to 2 mL. For 0.25 mg/mL microsomes, 50 μL of 20 mg/mL microsomes was added to 4 mL of 100 mM phosphate buffer and mixed evenly.
The test example compound was weighed, diluted to 10 mM with DMSO, and then diluted to 100 μM with 100 mM phosphate buffer.
The above data show that the example compounds of the present invention do not have strong inhibition, but all have weak inhibition on each CYP enzyme subtype, and the risk of DDI is small.
This experiment used a spontaneously hypertensive rat (SHR) model to evaluate the pharmacodynamic effect of the test compounds on the blood pressure and heart rate of the model.
Kent Scientific CODA non-invasive blood pressure system.
Spontaneously hypertensive rats (SHR) were provided by Beijing Vital River Laboratory Animal Technology Co., Ltd., male, 150-200 g, 13-15 weeks old, 50 rats.
After animals arrived at the experimental facility, the animals were adapted to the animal facility for 5-7 days. 4.2 After the adaptation period, the animals were adapted to the tail oversleeve restrain for 3 days, and the tail oversleeve restrain was performed twice a day. After the last restrain adaptation, the basal blood pressure was measured, and the animals were randomly divided into groups according to the basal blood pressure. There was no significant difference between the average systolic blood pressure of animals in each group, and the number of animals in each group met the requirements of statistical testing and pharmacodynamic guidelines. 4.3 On the second day after grouping, the animals were administered according to experimental design and grouping (P.O, 5 mL/kg), and the systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) of the animals were measured before administration and at 1, 2, 4, 6, 8 and 24 h after administration using tail oversleeve method.
Statistical differences between groups were analyzed by Two-way ANOVA test. Among them, P<0.05 indicated a significant difference, and P<0.01 indicated an extremely significant difference.
The results show that in the spontaneously hypertensive model, compared with the vehicle group, the example compounds 44, 45 and 49 of the present invention significantly reduced blood pressure (systolic blood pressure, diastolic blood pressure, mean arterial pressure) 1-8 h after administration in the 30 mpk administration group (P<0.05); in addition, no significant effect on heart rate was found in each administration group, and the safety was good.
