Abstract
Description
A class of cell programmed necrosis inhibitors and their preparation method and use Technical Field
[0001] The present invention belongs to the field of small molecule compounds, and specifically relates to a class of programmed cell necrosis inhibitors and preparation methods and uses thereof. Background Art
[0002] During development and aging, the human body is constantly undergoing a dynamic regulation of cell proliferation and death. Active cell death is essential for physiological activities such as normal development, resistance to pathogenic microbial invasion, and maintenance of internal homeostasis. Its dysregulation often leads to a variety of diseases, including developmental malformations, immune system disorders, neurodegenerative diseases, and cancer, and even individual death. Therefore, intervening in programmed cell death is of great significance for disease treatment research. Apoptosis was the first mechanism of programmed cell death to be elucidated, and in recent years, programmed cell death (necroptosis) has become a new hot topic in the field of cell death. Numerous studies have reported that programmed cell death, a key pathological feature, is present in a variety of degenerative diseases (e.g., Alzheimer's disease (AD), multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), and retinal degenerative diseases), ischemia-reperfusion injury (e.g., cerebral infarction, myocardial infarction), and pathogen infection.
[0003] On the other hand, the activation of programmed cell necrosis pathways is often accompanied by the occurrence of inflammation. Persistent inflammation may cause irreversible damage to human tissues or organs, and also promote the progression of a variety of diseases such as cardiovascular disease, diabetes, cancer, non-alcoholic fatty liver disease, degenerative diseases or metabolic syndrome, and is described as the root of all diseases. Various chronic inflammatory diseases, such as rheumatoid arthritis (RA), inflammatory bowel disease (IBD), psoriasis or hepatitis, not only seriously affect the health and quality of life of patients, but may also trigger fatal myocardial infarction or cancer; and acute inflammatory storms caused by infection, such as sepsis or severe pneumonia caused by new coronavirus infection, may directly endanger life; tumor immunotherapy using CAR-T cells or PD-1 / PD-L1 antibodies often has varying degrees of acute inflammatory side effects, seriously affecting the quality of life or life safety of patients. Furthermore, programmed necrosis and inflammation also play a role in regulating the tumor microenvironment: lung cancer cells can induce programmed necrosis in specific cells within the vascular wall, enabling them to pass through the circulatory system and metastasize. Overexpression of the main component of the necrosome in pancreatic cancer can induce expression of the chemokine CXCL1, thereby suppressing the body's immune response. Therefore, inhibiting programmed necrosis is recognized to be beneficial in the treatment and alleviation of various diseases.
[0004] Studies have shown that tumor necrosis factor α (TNF-α) is one of the main pathways that stimulates programmed necrosis and inflammation in cells in the body, and its downstream signaling pathway is also the necrosis signaling pathway with the most clear mechanism. In this pathway, RIPK1 plays a key regulatory role: by forming signaling complex I (Complex I) with the TNFα receptor protein TNFR1 and other regulatory factors (TRADD, TRAF2, cIAP1 / 2, etc.), it activates the IKK complex and the NF-κB inflammatory pathway; after kinase activity is activated, it enters the cytoplasm and forms Complex IIa with apoptotic factors (FADD, Caspase-3, etc.) to mediate the occurrence of cell apoptosis; or it activates RIPK3 and polymerizes with it to form the necrosome Complex IIb, ultimately inducing the occurrence of programmed cell necrosis (necroptosis). During the process of programmed necrosis, the cell membrane structure is destroyed and a large number of inflammatory factors are released, thereby inducing a chain reaction of inflammation and cell death. Studies have shown that genetic mutations in the RIPK1 gene (D324V, D324H) cause abnormal accumulation and activation of RIPK1 protein, leading to the occurrence of autoimmune diseases; during the aging process, mutational inactivation of upstream inhibitory regulatory factors (such as OPTN, TBK1, TAK1, A20, CYLD, etc.) can also lead to RIPK1 activation, thereby aggravating degenerative diseases and inflammatory conditions; in a variety of fungal or viral infections and organ ischemia-reperfusion injuries, RIPK1 is also abnormally activated, thereby inducing the occurrence of inflammatory cell death. In the treatment of central nervous system diseases, antibody drugs have the disadvantages of being difficult to penetrate the blood-brain barrier and immunogenicity, while many existing targeted small molecule drugs may affect the normal function of neuronal cells; at the same time, the inhibition of certain key immune pathways will inevitably affect the normal immune function of the human body, thereby bringing the risk of serious infection. Therefore, RIPK1 kinase is recognized as a potential therapeutic target for a variety of degenerative or inflammatory diseases.
[0005] In preclinical studies, the first-in-class RIPK1 inhibitor Necrostatin-1 (Nec-1) and its analogs have demonstrated clear therapeutic effects on a variety of degenerative diseases, inflammation, cancer and other diseases. For example, it has a relieving effect on AD, ALS, MS, Parkinson's disease (PD), Huntington's disease (PD), inflammatory bowel disease, age-related macular degeneration, etc.; it has a protective effect on psoriasis, retinitis pigmentosa, inflammatory bowel disease, autoimmune diseases, bombesin-induced acute pancreatitis and sepsis / systemic inflammatory response syndrome (SIRS); it can effectively alleviate ischemic brain injury, ischemic myocardial injury, retinal ischemia / reperfusion injury, retinal detachment-induced photoreceptor cell necrosis, glaucoma, renal ischemia-reperfusion injury, cisplatin-induced renal injury and traumatic brain injury; it can at least partially alleviate other diseases associated with RIPK1-dependent apoptosis, necrosis or cytokine production, including blood and solid organ malignancies, bacterial infections and viral infections (including tuberculosis, influenza, etc.) and lysosomal storage diseases (especially Gaucher disease). Currently, multiple RIPK1 inhibitors are also in clinical trials for the treatment of various autodegenerative or immune diseases. For example, Sanofi's SAR443820 is in Phase II clinical trials for ALS and MS, and its SAR443122 is in Phase II clinical trials for lupus erythematosus and ulcerative bowel disease.
[0006] However, existing RIPK1 inhibitors all have varying degrees of deficiencies. For one thing, chronic diseases associated with programmed cell death, particularly degenerative diseases of the central nervous system, place high demands on drug safety. For example, Sanofi's SAR443060, originally in Phase I clinical trials, was found to have chronic toxic side effects in primates even after reaching the Phase I endpoint, forcing it to be replaced with SAR443820 for clinical trials. Furthermore, most RIPK1 inhibitors in clinical trials are analogs of GSK2982772, and their shared structural framework limits the scope for optimizing drugability. Such inhibitors often fail to effectively inhibit RIPK1 in non-primates, which limits their validation in preclinical disease models and hinders the selection of clinical indications. Finally, RIPK1 inhibitors that are both highly active and brain-penetrating are very limited, and their long-term safety also requires further verification. Therefore, small-molecule RIPK1 kinase inhibitors with a different chemical structure than GSK2982772, combined with high activity, high specificity, and high blood-brain barrier penetration, remain both a challenge and a hot topic in the development of new clinical drugs for necroptosis-related diseases. In summary, there is an urgent need for new RIPK1 inhibitors and / or necroptosis inhibitors with novel chemical structures and enhanced pharmacokinetic and pharmacodynamic properties as candidate drugs for the prevention and treatment of diseases involving cell death and / or inflammation.

[0230] Biological Test Example 1: Inhibitory Activity Test of RIPK1 Inhibitors on Programmed Necrosis
[0231] The biological test scheme used was: the effect of the compound on TNF-induced FADD (Fas-associated death domain)-deficient Jurkat cells and L929 cells programmed necrosis.
[0232] In order to verify the inhibitory effect of the compounds of the present invention on programmed cell necrosis at the cellular level, cell types closely related to the RIP1 pathway, namely FADD-deficient Jurkat cells (a human peripheral blood leukemia T cell line) and L929 cells, were selected. Two different stimulation methods were used: tumor necrosis factor (TNFα) alone, or TNFα combined with mitochondrial-derived activator of cysteine aspartate (SMAC) SM164. Cell viability was calculated by detecting chemiluminescence values, thereby obtaining the biological activity of the compounds in inhibiting programmed cell necrosis.
[0233] Methods: FADD-deficient Jurkat cells (human peripheral blood leukemia T cell line) were cultured in vitro. After growing to the logarithmic growth phase, the cells were collected and centrifuged at 1000 rpm for 5 min. The supernatant was discarded and the cell concentration was adjusted to 2.5×10 5 / mL, the cells were seeded into 384-well plates, 40μl per well. 5μL of SM164 (50nM) and compound diluted in cell culture medium were added to the corresponding wells. After pretreatment at 37°C for 1h, 5μL of TNFα (50ng / mL) diluted in cell culture medium was added to each well of the stimulation group, and 5μL of culture medium was added to the control group. After culturing in a cell culture incubator (37°C, 5% CO2) for 14h, 15μl of Cell Titer-Glo solution was added to each well, incubated at room temperature for 30min, and chemiluminescence was detected to measure the intracellular ATP level. The unstimulated DMSO control wells were taken as 100% cell viability. L929 cells: L929 cells (mouse fibroblasts) cultured in vitro were digested and diluted to 6.25×10 4 / ml, the cells were seeded into 384-well plates, 40μl per well. Place in a cell culture incubator (37°C, 5% CO2) and culture for 12h. Add 5μL of SM164 (500nM) and compound diluted with cell culture medium to the corresponding wells. After pretreatment at 37°C for 1h, 5μL of TNFα (500ng / mL) diluted with cell culture medium was added to each well of the stimulation group, and 5μL of culture medium was added to the control group. After culture in a cell culture incubator (37°C, 5% CO2) for 14h, 15μl of Cell Titer-Glo solution was added to each well, incubated at room temperature for 30min, and chemiluminescence was detected to measure the intracellular ATP level. The unstimulated DMSO control well was taken as 100% cell viability. Prism Graphpad statistical software was used to calculate the compound EC50 The results are shown in Table 2.
[0234] Table 2. Test results of the inhibitory activity of RIPK1 inhibitors on programmed cell necrosis
[0235] The experimental results in Table 2 show that, whether stimulated by TNFα alone or in combination with SM164, the preferred compounds of the present invention, such as QY-18-26, QY-18-27, QY-20-53 and QY-20-54, exhibited stronger necroptosis inhibitory activity than the clinical inhibitor SAR443122 on human FADD-deficient Jurkat cells; and on mouse L929 cells in which SAR443122 was almost inactivated, the preferred compounds of the present invention were still able to effectively inhibit the occurrence of necroptosis.
[0236] Biological test example 2: Testing the effect of the representative compound QY-18-26 on RIPK1 kinase activity.
[0237] The biological assay protocol employed was to test the effect of compound QY-18-26 on the kinase activity of the RIPK1(1-330) protein. The purified RIPK1(1-330) protein retained its intact kinase domain and maintained good kinase activity. SAR443122, a known clinical RIPK1 inhibitor, was used as a control.
[0238] Methods: RIPK1 (1-330) protein with a final concentration of 2 μM and ATP (1X kinase buffer) with a final concentration of 5 μL were added to a 384-well plate. At least 3 replicate wells were set up for each group. The plates were reacted at 37°C for 2 h. 5 μL ADP-Glo reagent was added to stop the kinase reaction and remove residual ATP in the reaction system. The plates were allowed to stand at room temperature for 40 min. 10 μL Kinase Detection Reagent was added to convert ADP into ATP and introduce luciferase and luciferin for detecting ATP into the system. The plates were allowed to react at room temperature for 1 h. Luminescence was detected using the 7500 Fast Real-Time PCR System. The IC value of the compound inhibiting the kinase reaction was calculated using Prism Graphpad statistical software. 50 The experimental results are shown in Figure 1.
[0239] The experimental results showed that the representative compound QY-18-26 exhibited concentration-dependent effective inhibition of RIPK1 kinase, with an effective half-inhibitory concentration of 6.4 nM, which was better than the control SAR443122 (effective half-inhibitory concentration of 9.6 nM).
[0240] Biological Test Example 3: Pharmacokinetic Properties of Representative Compound QY-18-26
[0241] The biological test scheme used is: drug metabolism test of the compound in living mice.
[0242] To validate the pharmacokinetic properties of the compounds of this invention in vivo, representative compound QY-18-26 was tested in mice (n=3) using single oral gavage (PO, 10 mg / kg) or intravenous injection (IV, 1 mg / kg). The results are shown in Figure 2.
[0243] The results showed that after a single dose of QY-18-26, the concentration in mice rapidly reached a peak and showed a very high maximum blood concentration (C max ), exposure (AUC) and bioavailability (F). During the 24 hours after oral administration of 10 mg / kg, the blood drug concentration could be stably maintained above the effective inhibitory concentration (5 ng / mL) for most of the time.
[0244] Biological Test Example 4: Brain Penetration Properties of Representative Compound QY-18-26
[0245] The biological testing protocol used was: brain / blood drug concentration testing of the compound in living mice and rats.
[0246] To verify the brain penetration properties of the compounds of this invention in vivo, representative compound QY-18-26 was tested in mice (n=3) using single oral gavage (10 mg / kg) or intravenous injection (2 mg / kg) to determine brain and blood concentrations at different time points. Furthermore, single oral gavage (5 mg / kg) was used to determine brain and blood concentrations at different time points in rats (n=3). The results are shown in Figure 3.
[0247] After a single dose of QY-18-26, the concentration in the brain of mice and rats was approximately 40% of the concentration in plasma, and it maintained a stable brain-blood distribution at 4 hours. Its brain drug concentration was far above the effective inhibitory concentration (5ng / g), indicating that the compound has ideal brain penetrating properties.
[0248] Biological Test Example 5: Effect of Representative Compound QY-18-26 on Systemic Inflammatory Response Syndrome Induced by TNFα
[0249] Biological testing protocol employed: Systemic inflammatory response syndrome (SIRS), also known as inflammatory storm, refers to a systemic, nonspecific inflammatory response caused by infectious or non-infectious insults such as severe infection, multiple trauma, burns, ischemia-reperfusion, and acute pancreatitis. This condition results in the release of a large number of inflammatory factors, which in severe cases can lead to uncontrolled inflammatory responses, resulting in multiple organ failure and even death. Tail vein injection of tumor necrosis factor (TNF) induces SIRRS in mice, leading to hypothermia and death. The representative compound QY-18-26 was tested for its effect on TNFα-induced SIRRS, monitoring mice for changes in body temperature and mortality. A known RIPK1 inhibitor, Nec-1s, was used as a control; the clinical inhibitor SAR443122 has very poor inhibitory activity against murine RIPK1 and was therefore omitted.
[0250] Methods: Test compounds were dissolved in 0.5% carboxymethyl cellulose at the desired concentration one day in advance and sonicated overnight. Each mouse was gavaged with 200 μl of the solution. 20 minutes later, 10 mg of TNFα (dissolved in 125 μl of PBS) was injected via the tail vein. After injection, body temperature was monitored using an infrared thermometer. The effects of the compounds were calculated using Prism Graphpad software. The results are shown in Figure 4.
[0251] The experimental results showed that in the absence of inhibitors, all mice died within hours after being injected with TNFα; the compound QY-18-26 was able to effectively resist the hypothermia, inflammatory response and death caused by TNFα at a low dose (1 mg / kg).
