Anthranilic acid (ANA), a metabolite of tryptophan, was examined for its immunopotentiating properties. Administration of ANA (12 mg/kg/day, p.o.) significantly enhanced the development of adjuvant arthritis in rats, although not in a dose-related manner. ANA tended to enhance adjuvant disease moderately suppressed by pretreatment with cyclophosphamide (CY), an immunosuppressive agent. ANA (3-30 mg/kg/day, p.o.) also caused a dose-related enhancement in the antibody formation to sheep erythrocytes (SRBC) in mice.
