摘要:
This invention concerns novel antibiotic peptide and peptide derivates, especially for use in medicine. Further, the invention relates to compositions and methods for killing microbes, like bacteria or fungus, and methods to treat microbial infections. The invention further relates to a method for drug screening analysis. The peptides and peptide derivates have the general formula Sub 1 - X 1 N X 2 X 3 P V Y I P X 4 X 5 R P P H P - Sub 2 wherein X 1 is a neutral or positively charged moiety, X 2 is a polar or positively charged moiety, X 3 is a positively charged moiety, X 4 is a polar or positively charged moiety, X 5 is a proline or a proline derivate, Sub 1 being the free or modified N-terminus, and Sub 2 being the free or modified C-terminus. The peptides or peptide derivates according to the invention possess at least one of the following advantages compared to the natural occurring apidaecin peptides: (i) an increased half-live in mammalian serum due to a higher protease resistance and (ii) an increased antimicrobial activity against one or several bacterial strains, especially human pathogens, or fungus or other microbial infections (iii) show an enlarged spectrum of antimicrobial activity, (iv) do induce less resistance in microbes and (v) are not toxic to human cells including erythrocytes.

摘要:
An intracellular selection system allows screening for peptide bioactivity and stability. Randomized recombinant peptides are screened for bioactivity in a tightly regulated expression system, preferably derived from the wild-type lac operon. Bioactive peptides thus identified are inherently protease- and peptidase-resistant. Also provided are bioactive peptides stabilized by a stabilizing group at the N-terminus, the C-terminus, or both. The stabilizing group can be a small stable protein, such as the Rop protein, glutathione sulfotransferase, thioredoxin, maltose binding protein, or glutathione reductase, an alpha-helical moiety, or one or more proline residues.
摘要:
Novel recombinant allergens with multiple mutations and reduced IgE binding affinity are disclosed. The allergens are non-naturally occurring mutants of naturally-occurring allergens. The overall ∝-carbon backbone tertiary structure is essentially preserved. Also disclosed is a method for preparing such recombinant allergens as well as uses thereof.

Autoantigens and allergens can be expressed in transgenic plants, and the plants, or products derived therefrom, used as foods or beverages to prevent or treat autoimmune diseases or allergic reactions.
摘要:
A tryptic digestion-resistant, non-naturally occurring lytic peptide comprising a sequence of amino acid residues containing mainly alanine, valine and lysine amino acid residues, wherein the epsilon -amino groups of the lysine residues and the alpha -amino group of the N-terminal amino acid are sufficiently methylated to impart enhanced tryptic, chymotryptic, and aminopeptidase digestion resistance to the peptide. The secondary conformation of the peptide is an ordered periodic structure such as an amphipathic alpha -helix or a beta -pleated sheet. The compositions of the invention are suitable for in vivo administration. A method of making the same, to impart enhanced tryptic digestion-resistance thereto, comprising reductively alkylating the epsilon -amino groups of the lysine residues and the alpha -amino group of the N-terminal amino acid with a methyl-providing reagent in the presence of a heterocyclic amine-borane reducing agent for sufficient time and at sufficient conditions to methylate the alpha - and epsilon -amino groups to sufficient extent to confer enhanced proteolytic digestion-resistance to the peptide.
