<P>PROBLEM TO BE SOLVED: To provide a pharmaceutical composition and an additive to health-promoting food of a simple structure which have an effect on the activity of an NMDA-type glutamic acid receptor. <P>SOLUTION: The pharmaceutical composition and the additive to health-promoting food containing a dipeptide of which one amino acid is selected from the group consisting of glycine, glutamic acid, aspartic acid and serine inhibit the activity of the NMDA-type glutamic acid receptor or activate the NMDA-type glutamic acid receptor. The pharmaceutical composition and the additive to health-promoting food are easy to obtain, inexpensive and safe in vivo because the main component thereof has a simple structure of dipeptide. <P>COPYRIGHT: (C)2009,JPO&INPIT |
