  1. Summarized effects of 10 µM of amantadine, rimantadine, adamantane, xanthene, emodin, pyronin B, pyronin Y and HMA (hexamethylene-amiloride) on Protein E, Protein 3a, ORF7b and ORF10 expressing oocytes. Inhibitory effects on current activity are indicated as % inhibition. Not determined is indicated as ND. Adapted from ref. 4.
