Zusammenfassung:The present invention relates to novel Spergualin-related compounds represented by the general formula [I] R2 is a residue obtained by removing, from an amino acid or peptide, the hydroxyl group of the carboxyl group and, when R1 is a group other than -H, R2 is same as R1 , or a pharmacologically acceptable salt thereof. Said compounds or salts thereof have an immuno-modulating action. The invention further relates to pharmaceutical formulations having an immuno-modulating activity which contain such Spergualin-related compounds and a process for the manufacture of these compounds and preparations.
