摘要:
Disclosed is a pharmaceutical composition for inhibiting infection and replication of influenza A and B virus, and the manufacture thereof. The pharmaceutical composition is produced by a manufacture of low-temperature disintegrating cyanobacteria, comprising the steps of: (a) mixing cyanobacteria and non-organic solvent to form a suspension containing cyanobacteria; (b) freezing the suspension with a temperature below 0° C. to form a ice block and the ice block being melted at a low temperature, the whole step being repeated at least twice; (c) separating the cyanobacterial residues and extract solution of the suspension; and (d) collecting the isolated cyanobacterial extract solution; wherein the cyanobacterial extract solution is a solution containing cyanobacterial bioactive substances. The pharmaceutical composition is able to effectively inhibit binding of sialic acid and hemagglutinin of influenza A and/or B virus, so as to inhibit infection and replication of influenza virus. Further, this pharmaceutical composition is able to inhibit infection of influenza virus resistant to neuraminidase inhibitors.
摘要:
The present invention relates to use of bicistronic DNA constructs for identifying compounds that inhibits IRES-dependent translation activity of an infectious enterovirus (EV) or encephalomyocarditis virus (EMCV) without affecting CAP-dependent translation activity of a host subject. The compounds thus identified are useful in preparation of a medicament for treating EV or EMCV infection.
摘要:
This invention relates to compounds of the following formula: in which R1, R2, A1, A2, X, Y, m, n, p, x and y are as defined herein, pharmaceutical compositions comprising the compounds and use of the compounds in treating enterovirus infection.
