Composition for preventing virus infection comprising poly-gamma-glutamic acid

Abstract

The present invention relates to a pharmaceutical composition for inhibiting or preventing viral infection, which comprises an effective dose of poly-gamma-glutamic acid (γ-PGA), and more particularly, to a pharmaceutical composition, a functional food, and a feedstuff additive capable of inhibiting viral infection and preventing viral diseases, which comprise poly-gamma-glutamic acid having an infection-inhibiting effect against viruses, such as an influenza virus, inducing respiratory infection or systemic infection, as an effective ingredient. The composition containing poly-gamma-glutamic acid as an effective ingredient according to the present invention, is effective for use as an animal feedstuff additive or a pharmaceutical agent for preventing influenza virus infection and various viral diseases as well as a pharmaceutical composition and a functional food to promote human health.

1 . A pharmaceutical composition for inhibiting viral infection or preventing viral diseases, which comprises an effective dose of poly-gamma-glutamic acid. 
     
     
         2 . The composition according to  claim 1 , wherein the molecular weight of poly-gamma-glutamic acid is 1 kDa˜15,000 kDa. 
     
     
         3 . The composition according to  claim 1 , wherein the virus is capable of inducing respiratory infection or systemic infection. 
     
     
         4 . The composition according to  claim 1 , wherein the composition is a dispersive formulation in which poly-gamma-glutamic acid is diluted with ethanol. 
     
     
         5 . A functional food for inhibiting viral infection or preventing viral diseases, which comprises an effective dose of poly-gamma-glutamic acid. 
     
     
         6 . A feedstuff additive for inhibiting viral infection or preventing viral diseases, which comprises an effective dose of poly-gamma-glutamic acid.
