Abstract: Novel compounds that have been found effective in inhibiting PDZ domain interactions, and particularly interactions of PDZ domains in MAGIs with the oncogenic (tumor suppressor) protein PTEN and interactions between the PDZ domain in the Dishevelled (Dvl) protein and other proteins such as the Frizzled (Fz) protein, have the general formula The invention also includes combinatorial libraries, arrays and methods for screening and studying proteins using such compounds. Compounds of the invention have produced apoptosis in certain cell lines that overexpress the Dishevelled protein (Dvl); inhibiting Wnt signaling.

Abstract: The present invention provides a fast and efficient method for determining the three-dimensional conformation of a protein. The steps of the method of the invention include: 1) formation of physical distance constraints, e.g., forming intramolecular chemical crosslinks of known size between residues of a protein; 2) enriching the number of the molecules that have intramolecular chemical crosslinks in the reaction pool, e.g., using size separation to remove proteins with intermolecular bonds; 3) exposing the enriched reaction pool to a protease that cuts the protein at specific sites to produce peptide fragments; 4) measuring the size of the peptide fragments to determine linkage sites with a certain spatial relationship in the protein; and 5)interpreting the data produced to determine spatial geometry and protein structure based on the deduced spatial relationship of the linkage sites.

Abstract: The present invention relates to a novel class of compounds that are potent inhibitors of HIV reverse transcriptase and HIV integrase. In addition to being multienzyme inhibitors, the inventive compounds of the present invention are remarkable in at least two other respects. First, they do not appear to be toxic to cells at typical therapeutic concentrations. Second, they appear to be equally effective against mutant strains of HIV reverse transcriptase commonly found in patients who have developed resistance to current reverse transcriptase inhibitors. Because the inventive compounds show promise in combatting viral resistance and are potent inhibitors of both HIV reverse transcriptase and integrase, they are ideal candidates for use in combination with existing therapies or alone in treating AIDS or HIV infection.

Abstract: A method of preventing and treating a viral condition caused by an enveloped virus is described, comprising using a therapeutically effective amount of a compound selected from the group consisting of a substituted hydroquinone and the corresponding benzoquinone, wherein said hydroquinone comprises a 2-R.sup.1, 3-R.sup.2 -1,4-hydroquinone where at least one of R.sup.1 and R.sup.2 include a carbon linkage to the benzene ring of the hydroquinone. Particularly useful compounds include 5,8-dihydro-5,8-methano-1,4-naphthalenediol, 1,4-naphthoquinone, 3', 6'-dihydroxybenzo-norbornane, tert-butylhydroquinone, other diols, e.g. 1,5-naphthalenediol, and alkylated diols, e.g. 4-methoxy-1-naphthol.

Abstract: The present invention provides novel nucleic acid mimics (termed "PENAMs") comprising a peptidic backbone and nucleotidic sidechains; the sidechains being oriented in such a way that the PENAM is homomorphous to target nucleic acids with which it can effectively hydrogen bond. Homomorphism is achieved by the incorporation of unusual sterochemical centers, including D-chiral centers and quasi-chiral centers, into the peptidic backbone. The PENAMs are useful for targeting nucleic acid sequences in order to modulate their activity in an "antisense" manner. Targeting can also be used to detect, isolate or modify target nucleic acids.

Abstract: Non-peptide, protease-binding compounds are described as useful in the detection, labelling, and inhibition of retroviral proteases. Aryl piperidinyl derivatives and other compounds related in structure have been found to be HIV-1 and HIV-2 protease-binding compounds.
