China (Received may 16, 2011; CL-110409; E-mail: tangyl@iccas.ac.cn, liuy@ibp.ac.cn) The high gearly pathogenic avian in?uenza A virus typesets a global brat to benignant health. Avian in?uenza RNA pol ymerase protein PAC was use in the concealment of two herbal plant extracts for anti-in?uenza agents. As a result, chlorogenic caustic was identi?ed to be PAC ligand and was notice to inhibit polymerase activity. Hence, this charm revealed a potential antiin?uenza lead entangled and provided an important feel in the discovery of new anti-in?uenza medicines.

The high pathogenicity of avian in?uenza A virus strains of subtype H5N1 and its capability of contagion from birds to humans pose a global threat to human health.1 The increasing geographical distribution of this epizootic virus, which causes respiratory indisposition to infected raft with signi?c! ant morbidity and mortality, has aroused atrocious concerns about healthful methods for the disease. Most current anti-in?uenza medicates are every neuraminidase inhibitors or M2 ion transmission line blockers.2 However, the e?ectiveness of these drugs has been limited because of drug resistance.3,4 Actually, a single regeneration on the target protein may be su?cient to induce drug resistance.
