Abstract

Provided are a pharmaceutical composition for preventing or treating a coronavirus infection or infectious disease, a composition for disinfection, and a health functional food or feed composition, all including nano-sized graphene oxide, and a method of using the same. Since the nano-sized graphene oxide or a complex thereof has anti-coronavirus activity, the graphene oxide may be used for prevention or treatment of a coronavirus infection, or disinfection of coronaviruses.

Claims (11)

1 . A method for preventing or treating a coronavirus infection or infectious disease, comprising administering a pharmaceutical composition comprising nano-sized graphene oxide or a complex thereof to a subject in need thereof, wherein the nano-sized graphene oxide has a diameter of 100 nm or less.

2 . The method for preventing or treating a coronavirus infection or infectious disease of claim 1 , wherein the graphene oxide has a thickness of about 0.3 nm to about 10 nm.

3 . The method for preventing or treating a coronavirus infection or infectious disease of claim 1 , wherein the graphene oxide is present as a homogenized dispersion.

4 . The method for preventing or treating a coronavirus infection or infectious disease of claim 1 , wherein the coronavirus is selected from the group consisting of alphacoronaviruses, betacoronaviruses, gammacoronaviruses, and deltacoronaviruses.

5 . The method for preventing or treating a coronavirus infection or infectious disease of claim 1 , wherein the coronavirus is porcine epidemic diarrhea virus (PEDV), canine coronavirus (CCV), feline infectious peritonitis virus (FIPV), bovine coronavirus (BCoV or BCV), avian infectious bronchitis virus (IBV), transmissible gastroenteritis coronavirus (TGEV), severe acute respiratory syndrome coronavirus (SARS-COV), severe acute respiratory syndrome coronavirus 2 (SARS-COV-2), middle east respiratory syndrome coronavirus (MERS-CoV), or a combination thereof.

6 . The method for preventing or treating a coronavirus infection or infectious disease of claim 1 , wherein the coronavirus infectious disease is coronavirus cold, coronavirus enteritis, coronavirus diarrhea, coronavirus pneumonia, severe acute respiratory syndrome (SARS), middle east respiratory syndrome (MERS), coronavirus disease 2019 (COVID-19), acute respiratory distress syndrome (ARDS), avian infectious bronchitis, or a combination thereof.

7 . A method for disinfecting coronavirus, comprising spraying, applying, scattering, sprinkling, washing, or a combination thereof with a composition for anti-coronavirus disinfection comprising nano-sized graphene oxide or a complex thereof in the air, on a surface of an object, or on a mammal, wherein the graphene oxide has a diameter of 100 nm or less.

8 . The method for disinfecting coronavirus of claim 7 , wherein the graphene oxide has a thickness of about 0.3 nm to about 10 nm.

9 . The method for disinfecting coronavirus of claim 7 , wherein the graphene oxide is present as a homogenized dispersion.

10 . The method for disinfecting coronavirus of claim 7 , wherein the coronavirus is selected from the group consisting of alphacoronaviruses, betacoronaviruses, gammacoronaviruses, and deltacoronaviruses.

11 . The method for disinfecting coronavirus of claim 7 , wherein the coronavirus is porcine epidemic diarrhea virus (PEDV), canine coronavirus (CCV), feline infectious peritonitis virus (FIPV), bovine coronavirus (BCOV or BCV), avian infectious bronchitis virus (IBV), transmissible gastroenteritis coronavirus (TGEV), severe acute respiratory syndrome coronavirus (SARS-COV), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), middle east respiratory syndrome coronavirus (MERS-COV), or a combination thereof.
