Neuropeptide Having Relaxing Activity of Smooth Muscle

摘要

The present invention relates to a new pure peptides with a relaxation activity isolated from echinoderms, to a new pure peptides showing the smooth muscle relaxation activity has the amino acid sequence of SEQ ID NO: 2. More specifically. ; The peptide of the present invention while showing also a strong relaxation activity than the relaxation activity of the peptide S1 and S2 the known, consists of a small number of amino acids is expected to be useful to facilitate mass production muscle relaxants. ; Echinoderms, starfish (Asterina pectinifera), neurogenic peptide, active relaxation
