Patent ID: 7803766

Claim:
A gastrin compound which comprises an amino acid sequence comprising from the amino acid terminus Z—Y m —X n -AA 1 -AA 2 -AA 3 -AA 4 -AA 5 -AA 6 , wherein Z is human serum albumin; X n is Gly-Pro-Trp-Leu-Glu-Glu-Glu-Glu-Glu-Ala (SEQ ID NO:9). AA 1 -AA 2 -AA 3 -AA 4 -AA 5 -AA 6 is Tyr-Gly-Trp-Leu-Asp-Phe (SEQ ID NO:6) or Tyr-Gly-Trp-Met-Asp-Phe (SEQ ID NO:5), Y m is an optional spacer region comprising m amino acid residues of a small neutral amino acid, and wherein there is a cysteine residue at the amino terminus of Y wherein m is 1 or greater, or at the amino terminus of X when m is 0, providing that the gastrin compound binds a gastrin/CCK B receptor.
