DZ2002 (0.1, 1, 10 µM; 96 h) inhibits the mixed lymphocyte reaction (MLR) response. DZ2002 (0.1, 1, 10 µM; 24 h) inhibits IL-12 and TNF-α production from both mouse peritoneal exudate cells and humanTHP-1 Cells. DZ2002 (0.1, 1, 10 µM; 64 h) inhibits expression of B7 (CD80/CD86) on differentiated THP-1 cells[1].

DZ2002 (2, 10, 50 mg/kg; i.p.; twice) blocks the DNFB-induced DTH response. (DNFB-induced DTH is a Th1 cell-mediated immune response, in which IL-12 is highly expressed and macrophages have been shown to play an important role). DZ2002 (0.08, 2 mg/kg; i.p.; single daily for 7 days) significantly suppresses a delayed-type hypersensitivity reaction as well as antibody secretion[1]. DZ2002 (50, 100 mg/kg; p.o.; single daily for 4 weeks) exerts a potent anti-fibrotic effect on dermal fibrosis by reducing the production of collagen, facilitating its degradation and regulating expression of various soluble factors in SSc mice model[2].
