  • Publication number: 20030198648
    Abstract: The present invention relates to methods of identifying a molecule from a library of molecules that inhibits binding of human immunodeficiency virus nucleocapsid 7 polypeptide (NCp7) to an oligonucleotide which comprises admixing an NCp7 polypeptide with at one labeled HIV-1 psi-site oligonucleotide and an amount of the molecule to be tested under binding conditions; and determining the amount of oligonucleotide bound to the NCp7 polypeptide, wherein a decrease in the amount of oligonucleotide bound in the presence of the molecule compared with the amount of oligonucleotide bound in the absence of the molecule indicates that the molecule inhibits binding of NCp7 polypeptide to the oligonucleotide.

  • Patent number: 6001555
    Abstract: The present invention provides several classes of compounds which can be used to inactivate retroviruses, such as HIV-1, by attacking the CCHC zinc fingers of the viral nucleocapsid protein and ejecting the zinc therefrom. In addition, kits for identifying compounds that can react with CCHC zinc fingers of the nucleocapsid proteins of a large number of different retroviruses have also been developed. The kits of the present invention describe a set of specific tests and reagents that can be used to screen and identify compounds based on their ability to react with and disrupt retroviral zinc fingers in the viral NC proteins and, in turn, inactivate the retrovirus of interest.
