Disclosed herein control of plant-virus diseases by applying a compound obtained by reducing the reaction product of an n-alkylamine with a sugar or a salt thereof on the plant to be protected from the plant-virus as an active ingredient.
The present invention provides a pharmaceutical composition comprising an extract or combination of extracts having an antiviral, antibacterial, or immunomodulating property, wherein the extract or combination of extracts is obtained from a combination of plants wherein at least one plant is selected from each of the genuses Labiatae, Caprifoliaceae, and Oleaceae. A preferred extract is obtained from Radix scutellaria, Flos lonicera, and Fructus forsythiae. The present invention further provides a pharmaceutical composition comprising baicalin, chlorogenic acid and forsythiaside in isolated and purified form. The present invention further provides certain novel derivatives of baicalin, chlorogenic acid and forsythiaside. The present invention additionally provides processes for preparing the extracts as well as baicalin, chlorogenic acid, and forsythiaside in isolated and purified forms.
Provided are methods and compositions for treating hepatitis virus infections in mammals, especially humans. The methods comprise (1) administering N-substituted-1,5-dideoxy-1,5-imino-D-glucitol compounds in combination with nucleoside antiviral agents, nucleotide antiviral agents, mixtures thereof, or immunomodulating/immunostimulating agents, or (2) administering N-substituted-1,5-dideoxy-1,5-imino-D-glucitol compounds in combination with nucleoside antivirals agents, nucleotide antiviral agents, or mixtures thereof, and immunomodulating/immunostimulating agents.
N-Substituted-1,5-dideoxy-1,5-imino-D-glucitol compounds of Formula I are effective in treatment of hepatitis infections, including hepatitis B and hepatitis C. In treating hepatitis infections, the compounds of Formula I may be used alone, or in combination with another antiviral agent selected from among nucleosides, nucleotides, immunomodulators, immunostimulats or various combinations of such other agents.
