  • Patent number: 7335355
    Abstract: A method of identifying an agent that enhances the anti-microbial activity of cationic anti-microbial peptides by blocking the inhibitory effects of the proteinase/glycosaminoglycan pathway, which method comprises: (i) providing, as a first component, a cationic anti-microbial peptide; (ii) providing, as a second component, bacteria; (iii) providing, as a third component, part of all of the components of a proteinase/glycosaminoglycan pathway such that the third component reduces the antimicrobial effect of the first component, for example, a glycosaminoglycan or bacteria or bacteria and a proteoglycan or a bacterial proteinase or a bacterial proteinase and a proteoglycan; (iv) contacting the first, second and third components with a test agent under conditions that would permit the killing of the bacteria by the antimicrobial agent in the absence of the third component, and that would permit the inhibition of the anti-microbial activity of the first component by the third component in the absence of the test
