    摘要: The present invention relates to a method for producing peptides which have biological activity comprising: (i) identifying a region of a protein of interest which is homologous to a member of the immunoglobulin superfamily of molecules; (ii) synthesizing a peptide which comprises amino acid sequence found in the region of homology; and (iii) modifying the synthetic peptide such that it assumes a three-dimensional conformation which is biologically active. The invention is based, in part, on the discovery that a cyclic peptide comprising amino acid sequences of a CDR derived from an antibody directed toward a viral receptor molecule can be used to effectively inhibit the binding of virus to its receptor. The invention is also based in part on the discovery that a cyclic peptide corresponding to a portion of human immunodeficiency virus (HIV) gp120 that is homologous to immunoglobulins may be used to generate an anti-HIV immune response.

    摘要: A method for identifying a compound that has a biocidal effect against a selected organism involves screening from among known or unknown peptide or non-peptide molecules, a test molecule that binds selectively to a target sequence of a multi-helical lid of a heat shock protein of the organism. The binding of the test compound inhibits the protein folding activity of the protein. A specific embodiment of such a method is useful for identifying or designing a pharmaceutical or veterinary biocidal or antibiotic compound, preferably a pathogen and/or strain-specific compound. For this purpose, the compound does not bind to a heat shock protein that is homologous to the mammalian subject to be treated with the compound. Screening methods can encompass direct binding or competitive assays. Molecules or compounds identified by these methods are employed as biocides for pharmaceutical, veterinary, pesticide, insecticide and rodenticide uses, among others.
