Urumin (trifluoroacetate salt)

Urumin is a peptide originally isolated fromH. bahuvistara (South Indian frog) skin that has antiviral activity. It inhibits H1 hemagglutinin-containing human influenza A viruses by 60 to >90% and H3 hemagglutinin-containing viruses by less than 50%. Urumin specifically targets the H1 hemagglutinin stalk in an antiviral assay using a chimeric virus and in an ELISA assay and acts by actively destroying influenza virions. It reduces viral titers of drug-resistant and -sensitive strains of H1N1 virus in a plaque assay and in mice. Intranasal administration of urumin (20 µg) prior to a lethal dose of PR8 influenza increases survival, with 70% of urumin-treated mice surviving after 14 days compared with 20% of control animals.Molecular Formula: C129H198N42O35S2.
