Abstract

NEW MATERIAL:The compound of formula (R<1> is acyl obtained by removing hydroxyl group from diene higher fatty acid or triene higher fatty acid; R<2> is H or carbomethoxy having S-configuration). EXAMPLE:N, N'-Dilinoleylcystamine. USE:An immuno-activating agent. It has recovering activity from the immunosuppressive state, increasing action to the immune stimulation below a threshold level, and immunoregulating action, and is effective to infectious diseases, cancer, and rheumatism. PREPARATION:The compound of formula can be prepared by reacting cystamine or L-cystine with the above higher fatty acid in the presence of a condensation agent (preferably N, N'-dicyclohexylcarbodiimide, etc.). The diene higher fatty acid referred in the definition of R<1> is preferably linoleic acid, and the triene higher fatty acid is preferably alpha-linolenic acid.
