Abstract: The present invention is directed to compositions comprising inhibitors of hepatitis C virus (HCV) protease and one or more additional therapeutically effective agents. Uses of such compositions as HCV inhibitors and methods of treating infection by HCV by administration of such compositions are also disclosed.

Abstract: Human scFvs are disclosed which interact with a conformational epitope along the pre-hairpin, N-helix coiled coil structure within the heptad repeat 1 (HR1) region of gp41 of HIV. These antibodies, as well as IgG conversions, are shown to neutralize diverse HIV isolates. Isolated nucleic acid molecules are also disclosed which encode relevant portions of these antibodies, as well as the purified forms of the expressed antibodies or relevant antibody fragments, such as VH and VL chains. The antibody compositions disclosed within this specification may provide for a therapeutic treatment against HIV infection by reducing viral load levels within an infected individual, thus prolonging the asymptomatic phase of HIV infection. These antibodies will also be useful in assays to identify HIV antiviral compounds as well as allowing for the identification of candidate HIV vaccines, such as HIV peptide vaccines.

Abstract: Provided are methods of identifying inhibitors of ?-secretase that employ modified ?-secretase substrates. The modified ?-secretase substrates have ?-secretase cleavage sites that are altered from wild type. The amino acid sequences of the altered ?-secretase cleavage sites contain different amino acids in at least one of the positions P2-P1-P1?-P2? of the ?-secretase cleavage site. Many of the modified ?-secretase substrates are more efficient substrates for ?-secretase than are corresponding substrates having wild-type sequences, that is, these modified substrates are more susceptible to enzymatic breakdown by ?-secretase. Recombinant polynucleotide molecules encoding the modified ?-secretase substrates are provided. Antibodies that recognize cleavage products of the modified ?-secretase substrates are provided. Stable cell lines expressing the modified ?-secretase substrates are provided. Transgenic animals expressing the modified ?-secretase substrates are provided.

Abstract: Disclosed are methods for identifying and evaluating the binding properties of substances to the amyoid precursor protein (APP) or to ?-amyloid (A? fragments of APP. Also disclosed is a class of benzofuran derivatives of formula (I), which interact specifically with APP or A?, and block interaction of APP or A? with secreatase or APP or A? binding antibodies.

Abstract: The present invention is directed to 2-aminothiazole compounds which are aspartyl protease inhibitors, and are inhibitors of both the beta-secretase enzyme and HIV protease, and that are useful in the treatment of diseases in which the beta-secretase enzyme and HIV are involved, such as Alzheimer's disease, HIV Infection and AIDS. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the treatment of such diseases in which the beta-secretase enzyme and HIV protease are involved.

Abstract: Methods for identifying modulators of PPIL2 are described. The methods are particularly useful for identifying analytes that antagonize PPIL2's effect on processing of amyloid precursor protein to A? peptide and thus useful for identifying analytes that can be used for treating Alzheimer disease.

Abstract: The present invention provides DNA constructs, genetically engineered host cells, and methods for identifying inhibitors of amyloid precursor protein (APP) processing. The methods provide for the convenient identification, in a single assay, of inhibitors of ?-secretase and ?-secretase as well as other forms of APP processing. The methods rely on fusion proteins of APP and transcription factors in which APP processing releases the transcription factors, allowing the transcription factors to activate transcription of a reporter gene. Inhibitors are identified as substances that block or diminish transcription factor release from the fusion protein, thereby causing a diminution of reporter gene readout.

Abstract: The present invention provides an improved method for eliciting a therapeutic immune response in an individual infected with human immunodeficiency virus (“HIV”). The method comprises administering an adenoviral vaccine composition expressing an HIV antigen to an individual with controlled viremia. Immunization of infected individuals in this manner elicits a cellular-mediated immune response against the virus that is significant both in the level of the response and the breadth of the response. The therapeutic immune response that ensues is capable of effectively maintaining low titers of virus and, thus, offers the prospect of reducing individual dependency on antiviral therapy.

Abstract: Novel tetracyclic aromatic ketones are natural product compounds useful in the inhibition of HIV integrase, the prevention or treatment of infection by HIV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described. Further, the novel fungal cultures MF6388 (ATCC 74478), Sterile Fungus, and MF6591 (ATCC 74477), Ascochyta sp. are also disclosed. Further, the cultures Sterile Fungus MF6388 (ATCC 74478) and Ascochyta sp. MF6591 (ATCC 74477) are also disclosed, as well as processes for making compounds of the present invention employing the cultures.
