Description
Technical Field
The invention relates to the field of medicines, and particularly discloses application of a compound ZJU-37 in preparation of a medicine for preventing and/or treating liver diseases.
Background
Acute and chronic liver injury is a common disease in clinical at present, if the acute and chronic liver injury is not controlled and treated in time, the acute and chronic liver injury can develop into irreversible diseases such as severe hepatitis, liver failure and the like, wherein the fatality rate of the acute liver failure is as high as 80-97%. At present, no effective treatment means and medicine are available clinically for severe hepatitis and hepatic failure. Therefore, the development of new therapeutic drugs and development of new therapeutic means and methods are urgently needed to improve the survival rate of treating severe hepatitis. Studies have shown that the receptor interacting protein kinase RIP1 is involved in various liver diseases. The use of RIP1 protein kinase inhibitors can reduce cell death and relieve various inflammatory responses, but the specific mechanism is not clear. RIP1 kinase inhibition currently in clinical stage is mainly aimed at neurodegenerative diseases and autoimmune diseases, including ulcerative enteritis, psoriasis, rheumatoid arthritis and the like. Cell death in which RIP1 participates can promote tissue inflammation and injury, and even amplify tissue injury if not inhibited, so that development of the targeted RIP1 kinase activity has clinical requirements and wide application prospects.

FIG. 1 shows a comparison of the efficacy of compound ZJU-37 and Nec-1s on liver injury and systemic inflammation in a mouse model of acute liver failure; the graph A and the graph B show that the serum liver injury indexes ALT and AST levels of the LPS/GalN model group are obviously increased compared with those of a normal control group, the serum ALT and AST levels of a treatment group are obviously reduced, and the ALT and AST can be obviously improved by the compound ZJU-37 compared with commercial Nec-1 s. Serum ALT, AST can be reduced after Nec-1s treatment (LPS/GalN vs. Nec-1s:1053 + -107.7 vs.724.8 + -119.5). While ZJU-37 significantly reduced ALT (LPS/GalN vs. ZJU-37: 2110. + -. 307.2vs. 166. + -. 31.11) and AST (LPS/GalN vs. ZJU-37: 21053. + -. 107.7vs. 206.5. + -. 21.16) (FIG. A, B). We used CBA to measure the serum cytokine levels of each group. The results show that compound ZJU-37 reduces TNF α, IL-6, IFN- γ, MCP-1 production better than Nec-1s (FIGS. C-F). Also ZJU-37 can prolong mouse survival time compared to Nec-1s (FIG. G). The compound ZJU-37 or the commercialized Nec-1s with the same dose (5mg/kg) is administrated in the abdominal cavity 30 minutes before LPS/GalN modeling, and the compound ZJU-37 can obviously improve liver injury and general inflammation compared with the commercialized Nec-1 s.

The degree of necrosis of liver tissues and infiltration of inflammatory cells were significantly reduced in the compound ZJU-37-treated group and the Nec-1 s-treated group, compared to the model group (panels C, D); particularly, the compound ZJU-37 has the best curative effect, and pathological sections of liver tissues of mice show that the liver tissues have no necrosis and less inflammatory cell infiltration. By immunohistochemistry on liver neutrophils by using Ly6G, the result is consistent with HE staining, and the liver tissue neutrophile infiltration is remarkably reduced in both the compound ZJU-37 treatment group and the Nec-1s treatment group compared with the model group; especially, the compound ZJU-37 has obvious curative effect, and pathological sections of liver tissues of mice show that the liver tissues have no neutrophil infiltration (figures E-H). Scale bar 50 uM.

The compound ZJU-37 of the invention is the prior art and can be prepared by the prior method.
EXAMPLE 1 preparation of a solution of Compound ZJU-37
The experimental method comprises the following steps: the compound ZJU-37 is prepared by diluting a stock solution of the compound ZJU-37 prepared after DMSO cosolvent with PBS before injection to prepare a solvent of the compound ZJU-37.
EXAMPLE 2 study of LPS/GalN-induced acute liver failure liver injury and systemic inflammation in mice with the Compounds ZJU-37 and Nec-1s
The experimental method comprises the following steps:
the animal model is a research tool for verifying whether a new therapeutic drug and a new therapeutic means are effective, and the currently internationally adopted animal models for simulating liver failure include drug-induced liver failure models (p-acetaminophen models, LPS/GalN models, thioacetamide models, carbon tetrachloride models and the like), acute liver ischemia models, partial hepatectomy models and the like. The LPS/GalN model has the advantages of good repeatability, unobvious extrahepatic toxicity, near-clinical hepatic injury performance and the like, and is an ideal hepatic failure animal model.
Male C57BL/6 mice (purchased from Nanjing Biopharmaceutical research institute) at six weeks of age were randomly divided into a normal control group, a model group (LPS/GalN group), a compound ZJU-37 treatment group (5mg/kg ZJU-37+ LPS/GalN group), and a compound Nec-1s treatment group (5mg/kg Nec-1s + LPS/GalN group). Intraperitoneal injection is carried out on the compounds ZJU-37 and Nec-1s, and LPS/GalN (40 mu g/kg LPS +800mg/kg D-GalN) is subjected to intraperitoneal injection molding after 30 minutes; the model group replaced the solvent of compound ZJU-37 with an equal volume of solvent; the normal control group was not treated. LPS/GalN modeling and eye ball picking method for 6 hours are adopted to take blood for biochemistry and CBA detection.
The experimental results are as follows:
the experimental results are shown in fig. 1: the graph A and the graph B show that the serum liver injury indexes ALT and AST levels of the LPS/GalN model group are obviously increased compared with those of a normal control group, the serum ALT and AST levels of a treatment group are obviously reduced, and the ALT and AST can be obviously improved by the compound ZJU-37 compared with commercial Nec-1 s. Serum ALT, AST can be reduced after Nec-1s treatment (LPS/GalN vs. Nec-1s:1053 + -107.7 vs.724.8 + -119.5). While ZJU-37 significantly reduced ALT (LPS/GalN vs. ZJU-37: 2110. + -. 307.2vs. 166. + -. 31.11) and AST (LPS/GalN vs. ZJU-37: 21053. + -. 107.7vs. 206.5. + -. 21.16) (FIG. A, B). We used CBA to measure the serum cytokine levels of each group. The results show that compound ZJU-37 reduces TNF α, IL-6, IFN- γ, MCP-1 production better than Nec-1s (FIGS. C-F). Also ZJU-37 can prolong mouse survival time compared to Nec-1s (FIG. G). The compound ZJU-37 or the commercialized Nec-1s with the same dose (5mg/kg) is administrated in the abdominal cavity 30 minutes before LPS/GalN modeling, and the compound ZJU-37 can obviously improve liver injury and general inflammation compared with the commercialized Nec-1 s.
Namely, compared with the Nec-1s, the compound ZJU-37 can better reduce liver injury of mice acute liver failure induced by LPS/GalN and improve systemic inflammation under the condition of the same dosage.
EXAMPLE 3 study of LPS/GalN-induced acute liver failure liver pathology and neutrophil infiltration in mice by Compounds ZJU-37 and Nec-1s
The experimental method comprises the following steps:
male C57BL/6 mice (purchased from Nanjing Biopharmaceutical research institute) at six weeks of age were randomly divided into a normal control group, a model group (LPS/GalN group), a compound ZJU-37 treatment group (5mg/kg ZJU-37+ LPS/GalN group), and a compound Nec-1s treatment group (5mg/kg Nec-1s + LPS/GalN group). Intraperitoneal injection is carried out on the compounds ZJU-37 and Nec-1s, and LPS/GalN (40 mu g/kg LPS +800mg/kg D-GalN) is subjected to intraperitoneal injection molding after 30 minutes; the model group replaced the solvent of compound ZJU-37 with an equal volume of solvent; the normal control group was not treated. LPS/GalN model 6 hours later, leave the liver specimen and carry on HE and immune histochemical staining.
The experimental results are as follows:
the experimental results are shown in fig. 2: the graphs A and B show an LPS/GalN model group, and the HE staining of liver tissues shows that the necrosis of the liver tissues and the infiltration of inflammatory cells are obvious. The degree of necrosis of liver tissues and infiltration of inflammatory cells were significantly reduced in the compound ZJU-37-treated group and the Nec-1 s-treated group, compared to the model group (panels C, D); particularly, the compound ZJU-37 has the best curative effect, and pathological sections of liver tissues of mice show that the liver tissues have no necrosis and less inflammatory cell infiltration. By immunohistochemistry on liver neutrophils by using Ly6G, the result is consistent with HE staining, and the liver tissue neutrophile infiltration is remarkably reduced in both the compound ZJU-37 treatment group and the Nec-1s treatment group compared with the model group; especially, the compound ZJU-37 has obvious curative effect, and pathological sections of liver tissues of mice show that the liver tissues have no neutrophil infiltration (figures E-H). Scale bar 50 uM.
Namely, the compound ZJU-37 can better improve liver pathology of acute liver failure of mice induced by LPS/GalN and reduce infiltration of neutrophils under the condition of the same dosage.
EXAMPLE 4 Compound ZJU-37 inhibits apoptosis in liver tissue of LPS/GalN model mouse
The experimental method comprises the following steps:
male C57BL/6 mice (purchased from Nanjing Biopharmaceutical research institute) at six weeks of age were randomly divided into a normal control group, a model group (LPS/GalN group), a compound ZJU-37 treatment group (5mg/kg ZJU-37+ LPS/GalN group), and a compound Nec-1s treatment group (5mg/kg Nec-1s + LPS/GalN group). Intraperitoneal injection is carried out on the compounds ZJU-37 and Nec-1s, and LPS/GalN (40 mu g/kg LPS +800mg/kg D-GalN) is subjected to intraperitoneal injection molding after 30 minutes; the model group replaced the solvent of compound ZJU-37 with an equal volume of solvent; the normal control group was not treated. Liver tissue was left to TUNEL stain 6 hours after LPS/GalN modeling.
The experimental results are as follows:
the experimental results are shown in fig. 3: the TUNEL positive cells in the LPS/D-GalN model group were significantly increased compared to the normal control group (panels A and B), while the normal control group had almost no TUNEL positive signal, indicating that a large number of liver cells were apoptotic in the model group. Expression of TUNEL was significantly down-regulated in the treatment group; especially, the compound ZJU-37 showed the best effect, and pathological liver tissue sections of mice showed that the TUNEL signal was hardly detected in liver tissues (panels C and D).
Namely, the compound ZJU-37 can better improve the liver cell death of mice acute liver failure induced by LPS/GalN. This may also be a potential mechanism for the difference in the potency of the two drugs.
