Abstract
Disclosed are (1) a polypeptide represented by formula (I), or a pharmaceutically acceptable amide, ester or salt thereof: EQU His-Ser-Asp-Gly-Ile-Phe-Thr-Asp-Ser-Tyr-Ser-Arg-Tyr-Arg-Lys-Gln-NH-CHX-CO-A la-Val-Lys-Lys-Tyr-Y SEQ ID NO: 13 (I) wherein X is hydrogen atom; or a lower alkyl group which may be substituted with a member selected from the group consisting of hydroxy group, substituted or unsubstituted amino group, carboxyl group, carbamoyl group, and substituted or unsubstituted aromatic group; and Y is one of amino acids or peptides consisting of 1 to 16 amino acid residues counted from the N-terminal side of Leu-Ala-Ala-Val-Leu-Gly-Lys-Arg-Tyr-Lys-Gln-Arg-Val-Lys-Asn-Lys SEQ ID NO: 20, and (2) a pharmaceutical composition comprising a polypeptide represented by formula (I), or a pharmaceutically acceptable amide, ester or salt thereof, which has remarkable c-AMP activity and is useful as a nerve activating agent.
