  • Publication number: 20060252729
    Abstract: The present invention provides novel compounds with activity against infectious viruses. The compounds of the invention may inhibit retroviral reverse transcriptases and thus inhibit the replication of the virus. They are useful for treating human patients infected with a human retrovirus, such as human immunodeficiency virus (strains of HIV-1 or HIV-2) or human T-cell leukemia viruses (HTLV-I or HTLV-II) which results in acquired immunodeficiency syndrome (AIDS) and/or related diseases. The present invention also relates generally to the accumulation or retention of therapeutic compounds inside cells. The invention is more particularly related to attaining high concentrations of active metabolite molecules in HIV infected cells. Intracellular targeting may be achieved by methods and compositions which allow accumulation or retention of biologically active agents inside cells. Such effective targeting may be applicable to a variety of therapeutic formulations and procedures.

  • Patent number: 5705524
    Abstract: Tri- and tetra substituted thiepane and compositions having use as immunogens, therapeutics, diagnostics and for other industrial purposes are disclosed. The compositions inhibit proteolytic activity of viral enzymes and are useful for the inhibition of such enzymes as well as in assays for the detection of such enzymes. Embodiments in which antigenic polypeptides are bonded to the compositions are useful in raising antibodies against the thiepane haptens or the polypeptide. Labeled thiepanes of this invention are useful as diagnostic reagents.
