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.
