Abstract
An .alpha.,.alpha.-trehalose trimycolate represented by formula: ##STR1## (wherein R.sup.1 through R.sup.8 each represents a hydrogen atom or mycolic acid residue, and three of R.sup.1 through R.sup.8 are mycolic acid residues; these mycolic acid residues may, or may not be identical with each other). Since the said .alpha.,.alpha.-trehalose trimycolate possesses both immunopotentiating activity and antitumor activity on animals and is low in toxicity, it is expected to be applied to a protective drug against infection of various microbes, an antitumor agent and immunopotentiation at the time of decline in physical strength.
