Definitions
- the invention belongs to the field of antiviral drugs, and specifically relates to the application of foscarnet sodium in the preparation of drugs for the prevention and treatment of anti-coronavirus.
- New coronary pneumonia (COVID-19) is an infectious disease caused by a new type of coronavirus (SARS-Cov-2) infecting the human body. Its symptoms mainly include fever, fatigue, dry cough, dyspnea, and kidney failure. [The Lancet, 2020, 395(10223):507-513; The Lancet, 2020,395(10223):497-506]. New crown pneumonia began to report cases in December 2019, and then many countries, including South Korea, Japan, Thailand, Iran, Singapore, Germany, France, and the United States, have successively seen cases.
- SARS-Cov-2 coronavirus
- Coronaviruses belong to the genus Coronavirus in the family Coronaviridae (Coronaviridae).
- the virus of the genus Coronavirus is a positive-stranded single-stranded RNA virus with an envelope, with a diameter of about 80-120nm. Its genetic material is the largest among all RNA viruses, and generally only infects humans, mice, pigs, cats, and dogs. , Poultry vertebrates.
- the coronavirus was first isolated from chickens in 1937. Coronavirus particles are irregular in shape, about 60-220nm in diameter.
- SARS-Cov-2 virus particles The diameter of SARS-Cov-2 virus particles is between 60nm and 140nm, and there are 9-12nm spikes outside the envelope, resembling a corolla. Genome sequencing showed that SARS-Cov-2 is a single-stranded RNA coronavirus. By comparison with the gene sequences of other virus samples, it is found that SARS-Cov-2 is similar to SARS-CoV (79.5%) [Nature,2020] and bat coronavirus (96%) [bioRxiv,2020,2020.01.22.914952], and speculates The virus may originate from bats [bioRxiv, 2020, 2020.01.24.915157; Nature, 2020].
- the new type of coronavirus pneumonia is caused by a new type of coronavirus. It is the same type of coronavirus as SARS-CoV, which is known to cause atypical pneumonia, but is of a different type. Although its fatality rate is lower than SARS-CoV, it is far more infectious. In SARS-CoV. The global spread shows that the new coronavirus pneumonia epidemic still has the possibility of spreading. But so far, there is still no specific medicine that can cure the new type of coronavirus pneumonia. The development of effective antiviral drugs and vaccines has become the most urgent task at the moment. At present, the treatment of COVID-19 mainly relies on symptomatic adjuvant treatment, and there is still a lack of effective specific drugs and vaccines.
- Foscarnet sodium inhibits viral RNA polymerase, reverse transcriptase, and DNA polymerase by non-competitively inhibiting dNTPs, thereby inhibiting viral replication.
- Foscarnet sodium can effectively treat viral infections, such as skin infections, herpetic keratitis, genital infections, or infections throughout the body and brain.
- the present invention has carried out applied research on the antiviral efficacy of foscarnet sodium in coronavirus.
- the present invention provides foscarnet sodium or its pharmaceutically acceptable salts, isotopes, stereoisomers, mixtures of stereoisomers, tautomers, esters, amides or prodrugs in the preparation of prevention and/or treatment of coronavirus. Application in disease-causing drugs.
- the coronaviruses are the new coronaviruses SARS-Cov-2, SARS-CoV, HCoV 229E, NL63, OC43, HKU1 and MERS-CoV.
- foscarnet sodium or its pharmaceutically acceptable salts, isotopes, stereoisomers, mixtures of stereoisomers, tautomers, esters, amides or prodrugs, and other antiviral drugs Application of the prepared composition as an active ingredient in preparing a medicine for preventing and/or treating diseases caused by coronavirus.
- Another aspect of the present invention provides a pharmaceutical composition for the treatment or prevention of diseases caused by coronaviruses, the pharmaceutical composition comprising foscarnet sodium or its pharmaceutically acceptable salts, isotopes, stereoisomers, and stereoisomers Mixtures of conformers, tautomers, esters, amides or prodrugs.
- the oral preparation is selected from granules, powders, pills, tablets, capsules or oral liquids.
- Another aspect of the present invention provides the use of foscarnet sodium as a disinfectant against coronaviruses of the coronavirus family.
- a disinfectant for eliminating coronavirus contamination of the coronavirus family includes foscarnet sodium.
- Another aspect of the present invention provides a method for treating diseases caused by viruses of the coronavirus family, comprising adding a therapeutically effective amount of foscarnet sodium or a pharmaceutically acceptable salt, isotope, stereoisomer, or stereoisomer A mixture of isomers, tautomers, esters, amides, or prodrugs are administered to the subject.
- Another aspect of the present invention provides a method for preventing a subject from being infected with coronaviruses of the coronavirus family, which comprises adding a therapeutically effective amount of foscarnet sodium or a pharmaceutically acceptable salt, isotope, stereoisomer, or stereoisomer.
- Administration of a mixture of conformers, tautomers, esters or prodrugs is administered to the subject prior to infection.
- the drug or pharmaceutical composition does not contain glucocorticoid or mineralocorticoid.
- the present invention finds for the first time that foscarnet sodium has an antiviral effect on the novel coronavirus, can block the novel coronavirus from infecting host cells, and can be used as a disease treatment for the treatment of anti-coronavirus infection.
- Foscarnet sodium anti-new coronary pneumonia new coronavirus drug efficacy evaluation The pharmacological effect of foscarnet sodium is evaluated by the CCK8 method, and the half effective concentration (EC 50 ) of the new coronary pneumonia new coronavirus (SARS-Cov-2) is 0.89 ⁇ M, which has low toxicity , Has a good treatment window.
- the African green monkey kidney cells (VeroE6) were inoculated into 96-well plates at 3 ⁇ 10 5 cells/well, and placed in the minimum Eagle's medium (MEM; GibcoInvitrogen) containing 10% fetal bovine serum (FBS; GibcoInvitrogen). Incubate at 37°C with 5% CO 2 until the monolayer grows up. A 100-fold dilution of the novel coronavirus clinical isolates of the novel coronavirus pneumonia was inoculated into a 96-well plate full of monolayer cells, and cultured at 37°C and 5% CO 2 for two days (including the normal control group).
- MEM minimum Eagle's medium
- FBS fetal bovine serum
- the degree of disease was as high as 75%, placed in a -80°C ultra-low temperature refrigerator, repeated freezing and thawing once, collecting the amplified virus solution, centrifuged at 3000r/min for 30 minutes, removing the sediment, and placing the small tubes in the -80°C ultra-low temperature refrigerator Long-term preservation.
- the foscarnet powder is dissolved in DMSO, it is added to the culture solution and diluted to 20mg/mL.
