Embodiment 1

[0020] The preparation of embodiment one FC-99 solution

[0021] For compound FC-99, the stock solution of compound FC-99 prepared after being dissolved in DMSO was diluted with sterile saline before injection to prepare the working solution of compound FC-99.

Embodiment 2

[0022] Example 2 Effect of FC-99 on Survival Rate of D-GalN / LPS Acute Liver Failure Mice

[0023] 4-6 weeks C57BL / 6 mice, male (purchased from Nanjing University-Nanjing Institute of Biomedicine). The model strictly follows the method introduced in the literature (Sainan Zhang, Sci Rep, 2016, doi: 10.1038 / srep33206). D-GalN and LPS (purchased from Sigma-Aldrich). Each mouse was injected intraperitoneally with 500 μl of sterile saline containing 20 mg D-GalN and 10 μg / kg LPS, and the final concentrations were 1 μg / kg D-GalN and 10 μg / kg LPS, respectively.

[0024]Experimental grouping and treatment: randomly divided into normal control group (NS group), compound FC-99 group (100mg / kg), model group (LPS / D-GalN group), treatment low dose group (30mg / kg FC-99+ LPS / D-GalN group), treatment high dose group (100mg / kg FC-99+LPS / D-GalN group). The treatment low-dose group and the treatment high-dose group carried out the intraperitoneal injection of the compound FC-99 working soluti...

Embodiment 3

[0026] Example 3 FC-99 inhibits the elevation of serum transaminases in mice with acute liver failure induced by D-GalN / LPS

[0027] 4-6 weeks C57BL / 6 mice, male. Experimental grouping and treatment: randomly divided into normal control group (NS group), compound FC-99 group (100mg / kg), model group (LPS / D-GalN group), treatment low dose group (30mg / kg FC-99+ LPS / D-GalN group), treatment high dose group (100mg / kg FC-99+LPS / D-GalN group). Treatment low-dose group and treatment high-dose group carry out the intraperitoneal injection of compound FC-99 working solution by the dosage of 30mg / kg and 100mg / kg respectively, after 2 hours, LPS / D-GalN (10μg / kg LPS+1000mg / kg D -GalN) intraperitoneal injection for modeling; in the model group, an equal volume of normal saline was used instead of compound FC-99 working solution; in the normal control group, no treatment was performed, and an equal volume of normal saline was used instead of LPS / D-GalN and FC-99 working solution. After 24 ...

Abstract

The invention discloses application of FC-99 shown as a formula (I) in preparing drug for preventing or treating acute hepatic failure, particularly relates to application of FC-99 in inducing expression of Let-7a (microRNA Let-7A) to inhibit occurrence and development of hepatic failure so as to prevent or treat the hepatic failure and belongs to the field of biomedicine. By building an acute hepatic failure mouse animal model induced by D-aminogalactose combined with lipopolysaccharide and intervening fulminant hepatic failure through FC-99, a result shows that FC-99 can obviously lower transaminase, inhibit inflammation factor release, reduce hepatic cell apoptosis and maintain liver microscopic structure stable and can remarkably lower death rate of mice with acute hepatic failure; bioinformatic analysis and molecular biological detection find that FC-99 is realized by inducing high expression of Let-7a and inhibiting gene expression of IL-6, IRF4, CD86 and SOCS1 in a targeted manner. Therefore, research results show that the compound FC-99 can be applied in preparing drug for preventing or treating acute hepatic failure. In the above application, dosage range for injection andoral administration is 0.01-1000mg per day, and the range can be deviated according to illness degree or dosage form difference.

Description

technical field [0001] The invention relates to the prevention or treatment of liver failure by inhibiting the occurrence and development of liver failure by FC-99; specifically, the prevention or treatment of liver failure by FC-99 inducing the expression of Let-7a. technical background [0002] Acute liver failure (Acute liver failure, abbreviated as "ALF") is a type of severe liver damage caused by a variety of factors. A large number of liver cells die in a short period of time, which in turn leads to the synthesis, detoxification, excretion and biotransformation of the liver itself. A critical clinical syndrome with severe disorders; its etiology is complex, the disease develops rapidly, and the fatality rate is as high as about 50%, which seriously threatens the life safety of patients (Mark J.W.McPhail.et al., 2015, doi: 10.1097 / MOG.0000000000000174). my country is a country with a large population in the world. Every year, hundreds of thousands of people suffer from ...
