  • Peptide useful as a ligand
    Patent number: 6566077
    Abstract: A peptide of formula (I) (H2N—X1—Thr—X2—CO)n—R  (I) where X1 and X2, different one another, are an amino acid residue of arginine or tyrosine in configuration L or D, wherein the hydroxy group of threonine and tyrosine and the guanidine moiety of arginine may be protected by a compound conventionally used in peptide chemistry for protecting the hydroxy group and the guanidine moiety, respectively, n is 1,2, 3 or 4, and R, when n is 2,3 or 4, is a group suitable for forming a dimer, trimer or tetramer, while, when n is 1, R is OH, a single amino acid residue, or a peptide chain contains up to 7 amino acid residues.
