Abstract
Synthetic peptides of the monomer type with 13 to 33 amino acids, in linear form or in a form cyclized by means of inter-cysteine disulphide bridges, have the general formula (I):Δ-Z-TrpGlyCys-Θ-CysTyrThrSer-Ω (I)wherein Δ is a biotinyl radical, a biocytinyl radical, a hydrogen atom, an acetyl (CH3CO—) radical, an aliphatic chain which may contain one or two thiol, an aldehyde functional group, or an amine functional group, Z represents peptide sequence -Ξ1-Ser-Ξ2-, -Ξ1-Gln-Ξ2-, or -Ξ1-Asn-Ξ2-, wherein -Ξ1 represents a peptide sequence of 0 to 9 amino acids and -Ξ2 represents a peptide sequence of 0 to 5 amino acids, Θ is -Arg Gly Arg Leu Ile-(SEQ ID NO: 15), -Arg Gly Arg Leu Val-(SEQ ID NO: 16), -Arg Gly Lys Leu Ile- (SEQ ID NO: 17), -Arg Gly Lys Leu Val-(SEQ ID NO: 18), -Lys Gly Arg Leu Ile-(SEQ ID NO: 19), or -Lys Gly Arg Leu Val-(SEQ ID NO: 20), Ω, attached to the —CO— group of serine, is a hydroxyl (—OH) radical, an amino (—NH2) radical, an alkoxy radical having 1 to 6 carbon atoms, a peptide sequence of formula Val-Σ-Ψ wherein Σ represents a sequence of formula -(AA1)-Trp Asn-(AA2)-(AA3) wherein (AA1) represents an amino acid different from lysine, (AA2) represents an amino …
