Patent ID: 7524926

Claim:
An N-terminal- and/or C-terminal-chemically modified peptide, which peptide consists of an amino acid sequence selected from the group consisting of: (a) an amino acid sequence of from 7 to 23 contiguous amino acids of a reference sequence, GAQFSKTAAKGEAAAERPGEAAVA (SEQ ID NO:1); and (b) an amino acid sequence substantially identical to the sequence defined in (a); wherein (i) the C-terminal amino acid of said chemically modified peptide is chemically modified and the N-terminal amino acid of the peptide is optionally chemically modified; or (ii) the C-terminal amino acid of said chemically modified peptide is not chemically modified and the N-terminal amino acid of the peptide is chemically modified and is not myristoylated; with the proviso that said chemically modified peptide contains no more than 23 amino acids; and wherein said chemically modified peptide has a mucin hypersecretion-inhibiting effect when administered to a mammal in a mucin hypersecretion-inhibiting amount.
