Abstract

Abstract Synthetic compounds of the formula: R.sub.1 -Gln-R.sub.4 -R.sub.5 and the acid addition salts thereof are disclosed wherein R 1 and R 5 are each independently selected from the group consisting of hydrogen, hydroxy, the residue of an amino acid and the residue of a polypeptide and R 4 is selected from the group consisting of lysine and arginine residues; provided that R 1 and R 5 are not both hydrogen or both hydroxyl at the same time. The disclosure is also of intermediate compounds for preparing the compounds of the above formula and derivative compounds having the same biological activity. Disclosed also are pharmaceutical compositions wherein the essential active ingredient is a synthetic compound of the invention. The compounds and compositions of the invention are useful for the prevention, suppression, treatment and diagnosis of multiple sclerosis.
