Abstract: The present invention provides the means for producing libraries of peptide structures for drug screening applications that are capable of folding or assuming their native conformations independently of artificial scaffolds or flanking sequences in the proteins from which they are derived. The libraries can be highly diverse such that they are representative of the repertoire of protein structures existing in nature. The libraries can also be non-redundant or normalized such that the bias towards specific structures existing in source data sets and/or in nature is/are removed. In a particularly preferred embodiment, the present invention provides 30,000 independent fold structures produced by this method. The present invention also provides computer-readable media and systems comprising structural data in relation to the peptide libraries, and methods for displaying and screening the libraries.

Abstract: The present invention relates to improved and integrated methods for the characterisation of an interaction site on a target protein that modulates the phenotype of a mammalian cell, such as a phenotype other than death and/or reduced growth. Such methods of the present invention include those to identify a target protein modulates such a phenotype of a mammalian cell, and optionally to characterise an interaction site on said target protein. Such identification and characterisation methods are useful in the development of research tools and/or therapeutics, such protein/peptide or small molecule therapeutics. Accordingly, the present invention also relates to methods of: identification of a ligand, such as a small molecule ligand, that binds to such a target protein; and identification a compound being a candidate modulator of said phenotype of a mammalian cell.

Abstract: The present invention provides a topical composition comprising (i) an amount of an AP-1 signaling inhibitor sufficient to reduce, delay or prevent apoptosis and/or necrosis induced by dermal wounding and/or to induce and/or enhance proliferation of a cell; and (ii) a suitable carrier or excipient e.g., a topical carrier or excipient or other carrier or excipient for dermal application. For example, the AP-1 signaling inhibitor is a peptide analog comprising the sequence set forth in SEQ ID NO: 104. The present invention also provides a method of treating a dermal wound comprising topically administering said topical composition to a subject suffering from a dermal wound.

Abstract: Polypeptides are identified through an assay based on inhibiting AP-I signalling activity and others to treat acute respiratory distress syndrome (ARDS) and clinical disorders associated with the development of ARDS.

Abstract: The present invention provides compositions comprising peptidyl inhibitors of CD40L-dependent signalling that are not derived from a natural binding partner of CD40L such as CD40, or from a native CD40-CD40L interface. More particularly, the peptidyl inhibitors of the present invention are derived from natural sources that do not express CD40-CD40L costimulatory pathways. The invention also provides synthetic derivatives and analogs of the peptidyl inhibitors having enhanced binding affinity for CD40L or enhanced inhibitory activity relative to their parent molecules.

Abstract: The present invention provides a non-hybrid screening method for the identification and/or isolation of a peptide that is capable of modulating a phenotype in a cell, tissue or organism. For example, the non-hybrid screening method identifies a peptide that is derived from an organism that is unrelated to the cell, tissue or organism. Alternatively, or in addition, the non-hybrid screening method identifies a peptide that is capable of rescuing the cell, tissue or organism from cell death or inducing a cell, tissue or organism to grow. The present invention also provides a non-hybrid screening method for identifying a peptide that is useful for treating a disease and/or disorder.
