COMPOUNDS OBTAINED FROM SALVIA SPECIES HAVING ANTIVIRAL ACTIVITY

摘要

The present invention provides a composition containing a molecule having at least one residue from β- (3,4-dihydroxyphenyl) lactic acid and / or coffee acid found in an extract of plant genus Salvia, wherein the residue is of the formula Represented by I, the active agent has a molecular weight of at least 190 Daltons. Preferred types of reagents are those that combine to form dimers, trimers, tetramers and larger polymers containing these residues, most preferred are salvianolic acid dimers, trimers, tetramers and larger polymers. These compounds and compositions may be administered systemically or locally to pharmaceutically acceptable carriers and excipients to treat viral infections.;Formula I
