  • Patent number: 8093046
    Abstract: The invention provides a recombinant multi-functional chimera of CVN and 12p1. Chimeras of CVN and 12p1 present a model for targeting gp120 at two discrete sites, by two different modes of inhibition and with increasing potency versus either component alone. A chimera of the invention combines the high affinity suppression of viral activity by CVN with the allosteric suppression of viral envelope binding to both CD4 and co-receptor by 12p1.

  • Publication number: 20100104580
    Abstract: The present invention provides compositions and methods useful in the prevention and treatment of HIV-1 infection in a host subject. High affinity binding of an allosteric dual antagonist to HIV-1 gp120 induces a conformational change in the gp 120 protein that traps the gp 120 protein in a three-dimensional structure that suppresses its function and exposes novel antigenic epitopes to host immune surveillance.
