Patent ID: 6872702

Claim:
A peptide comprising monomeric building blocks and having the general structural formula (I): in which X 21 to X 30 each denotes an aminocarboxylic acid and X 21 and X 29 are bridged together, Y is a spacer group that can couple the peptide to carrier substances n and m are each independently 0 or 1, and the monomeric building blocks are linked by —NR 1 CO— or —CONR 1 — bonds where R 1 in each case independently denotes hydrogen, methyl or ethyl, and wherein the amino acid residues X 21 -X 30 each independently have one of the following meanings: (i) X 21 and X 29 are each independently an aminocarboxylic acid residue with an SH side chain or X 21 and X 29 are together two aminocarboxylic acid residues which are bridged by a thioether bond; (ii) X 22 and X 27 are each independently an aminocarboxylic acid residue with an aliphatic side chain; (iii) X 23 is an aminocarboxylic acid residue with a basic or an aliphatic hydrophilic side chain; (iv) X 24 , X 25 and X 30 are each independently an aminocarboxylic acid residue with an aromatic side chain, (v) X 26 is an aminocarboxylic acid residue with an aliphatic side chain, and (vi) X 28 is an aminocarboxylic acid residue with an aliphatic side chain; and a pharmaceutically compatible salt or derivative thereof.
