, in which the PEG residue is attached via a suitable spacer W to the N-atom, or
a residue
NH—Y-Z-PEG

,
in which
Y denotes a single chemical bond or a genetically coded amino acids from the group S, C, K or R and in which
Z denotes a spacer, via which a polyethylene glycol (PEG)-residue can be attached, as well as their physiologically acceptable salts,
and in which additionally
β denotes an amino acid, whether genetically coded or not, or a peptidomimetic element, which have the additional property of inducing a bend or turn in the peptide backbone.
Such amino acids include without limitation L-proline, D-proline, L-hydroxyproline, D-hydroxyproline, L-(O-benzyl)-hydroxyproline, D-(O-benzyl)-hydroxyproline, L-(O-tert. butyl)-hydroxyproline, 4-(O-2-naphtyl)-hydroxyproline, 4-(O-2-naphtyl-methyl)-hydroxyproline, 4-(O-phenyl)-hydroxyproline, 4-(4-phenyl-benzyl)-proline, cis-3-phenyl-proline, cis-4-phenyl-proline, trans-4-phenyl-proline, cis-5-phenyl-proline, trans-5-phenyl-proline, 4-benzyl-proline, 4-bromobenzyl-proline, 4-cyclohexyl-proline, 4-fluor-proline, L-tetrahydroisoquinoline-2-carboxylic acid (L-Tic), all diastereomers of octahydro-indole-2-carboxylic acid (Oic), and all diastereomers of 1-aza-bicyclo[3,3,0]octane-2-carboxylic acid or a residue selected from a group of peptidomimetic residues.
