Patent ID: 8853359

Claim:
A peptide selected from the group consisting of: (a) an amino acid sequence represented by Ala-Tyr-Gln-Leu-Glu-His-Thr-Phe-Gln-DTrp-Leu-Leu-NH 2 (SEQ ID NO: 4); (b) a partial sequence of SEQ ID NO: 4 consisting of 6 to 11 consecutive amino acids including at least the C-terminal Thr-Phe-Gln-DTrp-Leu-Leu-NH 2 (SEQ ID NO: 8); and (c) an amino acid sequence consisting of sequence (a) or (b), modified with either a deletion of a single amino acid, a substitution of a single amino acid, or an addition of from 1 to 5 amino acids at a position other than DTrp and C-terminal Leu-NH 2 , wherein the modified amino acid sequence of (a) or (b) excludes an amino acid sequence where Phe is substituted with DTrp.
