TECHNICAL FIELD
[0001] The present application relates to the field of medicine, and particularly relates to application of GLX351322 in preparation of a medicine for preventing and treating hemorrhagic stroke and the medicine. BACKGROUND
[0002] Stroke, also known as cerebral apoplexy or cerebral vascular accident, is an acute cerebrovascular disease. This disease is divided into ischemic stroke (cerebral infarction) and hemorrhagic stroke (cerebral hemorrhage), and the hemorrhagic stroke accounts for 10%-15% of the mortality rate of stroke.
[0003] Cerebral hemorrhage is due to the rupture of cerebral blood vessels, leading to blood forming a hematoma to compress the brain tissue, and first causing primary brain injury. The hematoma formation and expansion cause the space-occupying effect, and further cause mechanical damage of the adjacent tissue and reduction of cerebral perfusion, and then trigger a series of physiological and pathological changes such as oxidative stress and inflammatory response, leading to cell death and tissue necrosis

[0005] At present, there is no relevant research and report on the prevention and treatment effect of GLX351322 on hemorrhagic stroke. For this reason, the inventors of the present application established a collagenase-induced mouse brain hemorrhage model (ICH) and studied the protective effect of GLX351322 on the in vivo brain hemorrhage model. SUMMARY
[0006] The present application provides the application of GLX351322 in the preparation of a drug for preventing and treating hemorrhagic stroke and the drug, and the purpose is to seek the application of GLX351322 as an effective ingredient in the preparation of a drug for preventing and treating hemorrhagic stroke and the drug.
[0007] To achieve the above purpose, the first technical solution adopted by the present application is: the application of GLX351322 in the preparation of a drug for preventing and treating hemorrhagic stroke, wherein the molecular formula of GLX351322 is C 21 H 25 N3O5S, the CAS number is 835598-94-2, the molecular weight is 431.51, and the chemical structural formula is shown as formula I: Formula I.
[0008] To achieve the above object, the second technical solution adopted by the present application is: a drug for preventing and treating hemorrhagic stroke, which is characterized by comprising GLX351322 and a pharmaceutically acceptable carrier, wherein the molecular formula of the GLX351322 is C 21 H 25 N3O5S, the CAS number is 835598-94-2, the molecular weight is 431.51, and the chemical structural formula is shown as formula I: Formula I.
[0009] The related content in the above first and second technical solutions is explained as follows: 1. In the above two technical solutions, the GLX351322 is an existing substance, which is an NADPH oxidase 4 (NOX4) inhibitor, inhibits hydrogen peroxide production in NOX4 overexpressing cells, and the IC 50 value is 5 μM, and can penetrate the blood-brain barrier. The molecular formula of GLX351322 is C 21 H 25 N3O5S, the CAS number is 835598-94-2, the molecular weight is 431.51, and the chemical structural formula is shown as formula I. The common name is GLX351322, the English name is GLX351322, and the Chinese name is CS-2871. According to existing research, the mechanism of action of GLX351322 is to inhibit the enzyme activity of NOX4, rather than directly reduce the expression level of NOX4 protein. The specific conclusions are as follows: (1) GLX351322 as a NOX4 activity inhibitor GLX351322 reduces the catalytic production of hydrogen peroxide (H2O2) by blocking the activity of NOX4 protein. In NOX4 overexpressing cell models, the IC50 value of the compound for inhibiting H2O2 production is 5 μM.
[0010] (2) Action mode unrelated to protein expression Existing literature does not mention the effect of GLX351322 on the expression amount of NOX4 protein, and all studies focus on the inhibition of enzyme activity or the generation of downstream oxidation products. For example: one is that GLX351322 does not reduce the NOX4 protein level in tetracycline-induced NOX4 overexpressing cells, but directly inhibits its function. Two is that the mechanism of action of other NOX4 inhibitors (such as GKT136901) is also described as selectively inhibiting enzyme activity rather than regulating protein expression.
[0011] In summary, GLX351322 mainly plays a role by inhibiting the enzyme activity of NOX4, and there is currently no evidence that it affects the expression of NOX4 protein, nor is there evidence that it prevents and treats hemorrhagic stroke. The application of GLX351322 in medicine is described in the background art of the present application.

[0023] Mechanism of action of the present invention: 1. Mechanisms of cell death caused by cerebral hemorrhage Cerebral hemorrhage is caused by the rupture of a blood vessel in the brain, which leads to the formation of a hematoma that compresses brain tissue. This initially causes primary brain injury. The formation and expansion of the hematoma result in a space-occupying effect, which in turn causes mechanical damage to adjacent tissues and reduced brain perfusion. This then triggers a series of physiological and pathological changes, such as oxidative stress and inflammatory responses, leading to cell death and tissue necrosis.
[0024] 2. Mechanism of action of GLX351322 in preventing and treating cerebral hemorrhage The inventors have shown that oxidative stress is one of the main pathological mechanisms of hemorrhagic brain injury: when blood pressure presses on brain tissue, red blood cell lysate iron ions, hemoglobin, thrombin, etc. can induce oxidative stress, including when inflammatory cells are stimulated to release a large amount of ROS (Reactive Oxygen Species, ROS), when ROS is produced too much and exceeds the cell's own antioxidant capacity, it will cause cell tissue damage by directly oxidizing cell proteins, lipids and DNA or participating in cell death signaling pathways

See Kleinschnitz, C., et al., Post-stroke inhibition of induced NADPH oxidase type 4 prevents oxidative stress and neurodegeneration. PLoS Biol, 2010. 8(9).
[0025] In addition, in this new indication of hemorrhagic stroke, the protective mechanism of GLX351322 not only directly targets NOX4 enzyme activity to inhibit oxidative stress and inflammation, but also relies on the synergistic regulation of the integrated stress response (ISR)-eIF2a-ATF4-NOX4-ROS pathway, which is a completely new mechanism that has not been involved in known studies. After the occurrence of hemorrhagic stroke, oxidative stress and inflammation caused by hematoma compression and blood component decomposition are effective inducing factors for ISR. Activation of ISR can promote eIF2a phosphorylation and induce ATF4 expression

see Petry A, et al. CrossTalk Between p22phox and ATF4 in the Endothelial Unfolded Protein Response. Antioxid Redox Signal. 2019;30(1):40-55.
[0026] 3. The essential difference between the induction causes of hemorrhagic stroke and known indications and the mechanism of action of GLX351322 The mechanism of action of GLX351322 in known indications is centered on "directly targeting NOX4 enzyme activity to inhibit oxidative stress and inflammation". For example: in Parkinson's disease, the core cause is the aggregation of alpha-synuclein and the degeneration of dopaminergic neurons, GLX351322 directly inhibits NOX4-mediated ferroptosis of dopaminergic neurons, reduces neuronal damage in the substantia nigra of the midbrain, and the core is the toxic effect of oxidative stress downstream of NOX4 on specific neurons; in Alzheimer's disease, amyloid deposition and tau protein hyperphosphorylation trigger neuroinflammation and synaptic loss, GLX351322 reduces amyloid deposition-related oxidative stress by reducing hippocampal NOX4 enzyme activity to protect synaptic function; in osteoarthritis and retinal inflammation, the main cause is mechanical damage or immune complex deposition to activate the TLR4 / NF-κB inflammatory pathway, GLX351322 reduces local tissue ROS production and inflammatory factor release by inhibiting NOX4 enzyme activity; in cancer (such as colon cancer), the main effect of GLX351322 is to inhibit proliferation by reducing oxidative stress in the tumor microenvironment through inhibition of NOX4. Therefore, in known indications, GLX35122 is limited to a single role of directly inhibiting NOX4 enzyme activity, without involving the influence of GLX351322 on the transcriptional regulation and protein expression of NOX4, and even less involving the whole new mechanism of GLX351322 acting on the ISR-eIF2α-ATF4-NOX4-ROS-eIF2α cycle cascade effect. In the hemorrhagic stroke of the present application, GLX351322 not only directly inhibits NOX4 enzyme activity, but also blocks the ISR-eIF2α-ATF4-NOX4-ROS cycle, blocks the abnormal activation of NOX4 mediated by ATF4, and reduces the protein expression of ATF4 and NOX4, forming a dual action mode of "downstream NOX4 enzyme activity inhibition + upstream ATF4 regulation NOX4 transcription blockage" to reduce brain hemorrhage damage. Therefore, this mechanism breaks through the technical inspiration that cannot be obtained from known uses.
[0027] In addition, the pathogenic cause and pathological changes of hemorrhagic stroke are hematoma formation caused by cerebral vascular rupture, not neuronal degeneration, protein deposition or chronic inflammation, which are completely different from the pathogenic cause and pathological changes of known indications.
[0028] In summary, hemorrhagic stroke and known indications differ significantly in pathogenic cause and pathological change; and in hemorrhagic stroke and known indications, there are essential differences in the regulatory pathways of the mechanism of action of GLX351322, which fully prove the creativity of the new indication of the present application and do not belong to the simple extension based on known mechanisms.
[0029] In addition, the drugs for resisting oxidative stress also include nicotinamide riboside (NR) and reduced nicotinamide adenine dinucleotide phosphate (NADPH). Nicotinamide riboside (NR) can increase the levels of NAD and NADPH, and both nicotinamide riboside (NR) and reduced nicotinamide adenine dinucleotide phosphate (NADPH) can inhibit oxidative stress. Therefore, GLX351322 can be combined with nicotinamide riboside (NR) or / and reduced nicotinamide adenine dinucleotide phosphate (NADPH) and has a synergistic effect.
[0030] In addition, the kinase inhibitors in the ISR signaling pathway can also include PERK kinase inhibitors GSK2606414 and GSK2656157, the eIF2 phosphatase inhibitor Salubrinal, and the integrated stress response inhibitor trans-ISRIB (ISR inhibitor ISRIB). Since the PERK kinase inhibitor GSK2606414 has an inhibitory effect on the activation of PERK in cells, the PERK kinase inhibitor GSK2656157 is an ATP-competitive inhibitor of PERK enzyme activity, the eIF2 phosphatase inhibitor Salubrinal is a selective eIF2α dephosphorylation inhibitor, can inhibit ER stress-mediated apoptosis, and the integrated stress response inhibitor trans-ISRIB can enhance the activity of eIF2B to inhibit ISR. Therefore, GLX351322 can be combined with the PERK kinase inhibitor GSK2606414, the PERK kinase inhibitor GSK2656157, the eIF2 phosphatase inhibitor Salubrinal, and the integrated stress response inhibitor trans-ISRIB and has a synergistic effect.
[0031] The application of GLX351322 in the treatment of hemorrhagic stroke has the following advantages: 1. GLX351322 can significantly reduce the volume of hemorrhage by 20-30% in animal experiments, can resist oxidative stress, inflammatory response, and block the ISR-eIF2α-ATF4-NOX4-ROS cycle, and has a significant neuroprotective effect.
[0032] 2. GLX351322 is relatively safe as an effective active ingredient in the prevention and treatment of hemorrhagic stroke. The dose of GLX351322 used in the application is small, and it is presumed to have less toxicity and be relatively safe. In addition, relevant literature has shown that when rats are given a dose of 10 mg / kg by gavage, pharmacokinetic determination shows that GLX351322 can quickly enter the bloodstream with a half-life of 3 hours. GLX351322 has almost no toxicity when given a dose of 5 mg / kg intraperitoneally for 2 weeks in mice. Therefore, it can be considered that GLX351322 has less toxicity and is relatively safe in the treatment of hemorrhagic stroke.
[0033] 3. If GLX351322 has neuroprotective effect due to inhibiting oxidative stress and blocking ISR-eIF2α-ATF4-NOX4-ROS cycle, considering the harmful effects of oxidative stress and ISR-eIF2α-ATF4-NOX4-ROS cycle in some neurodegenerative diseases, GLX351322 can also have therapeutic effect on other neurodegenerative diseases such as Parkinson's disease, Huntington's disease, Alzheimer's disease, etc. BRIEF DESCRIPTION OF DRAWINGS
