DRAMP20909

Comments Information

    • Function

    • Inhibits hepatitis C virus(HCV) infection via inactivating infectious viral particle. However, it cannot suppress established infection because of the poor cellular uptake and restriction of endosomes.

Literature Information

  • ·Literature 1

    • Title

    • Design of histidine-rich peptides with enhanced bioavailability and inhibitory activity against hepatitis C virus.
