Anti-Influenza Virus (H5N1) Activity Screening on the Phloroglucinols from Rhizomes of Dryopteris crassirhizoma.

For screening the active phloroglucinols on influenza virus (H5N1) from NaKai, a database was established including twenty-three phloroglucinols that had been isolated from . Their inhibitory effect on the neuraminidase (NA) of influenza virus H5N1 was screened by molecular docking. As a result, three candidates were selected.
