Comments Information

    • MOA

    • Probably acts by disturbing membrane functions with its amphipathic structure. Binds to healthy erythrocytes (this binding is receptor independent), and has strong hemolytic activity. Does not bind to P.falciparum infected erythrocytes, but accumulates within the parasite.

    • Pharmaceutical use

    • Derivatives of this peptide may be used as therapeutic agents to treat bacterial infections and malaria, and to prevent infection by herpes simplex virus type 1 and HIV-1.
