Artocarpus tonkinensis A Chev. ex Gagnep (Moraceae) is a tree found in northern Vietnam used in VTM by the Hmong ethnic
minority to treat arthritis and backache. Intraperitoneal injections of A. tonkinensis extract decreased both arthritis incidence
and severity and delayed disease onset in rats with collagen-induced arthritis. In vitro, an extract induced apoptosis in lymph
node cell cultures, inhibited mitogen-induced T-cell proliferation, and induced apoptosis of activated LN-derived lymphocytes. In
addition, four individual active components isolated from A. tonkinensis have anti-inflammatory effects which correlate with the
tree’s inhibition of mitogen-induced T-cell proliferation. These extracts also inhibited production of cytokines, such as tumor necrosis
factor-α and interferon-γ, in mitogen-stimulated T cells. The authors postulated that suppression of T-cell proliferation and cytokine
production by A. tonkinensis flavonoids contribute to reduced arthritis severity after experimentally-induced arthritis. A. tonkinensis
compounds were also tested for anti-cancer activity, revealing that maesopsin 4-O-β-D-glucoside (TAT-2) has anti-proliferative
effects on acute myeloid leukemia cells and modulates expression of 19 genes, including hemeoxigenase-1 (HMOX-1), sulphiredoxin
1 homolog (SRXN1), and breast carcinoma amplified sequence 3 (BCAS3). TAT-2 showed also activity against lung cancer in vivo.
Other compounds isolated from A. tonkinensis roots, such as cyclocommunol, isocyclomulberrin, cudraflavone C and morusin, also
exhibited cytotoxicity against hepatocellular carcinoma (SMMC-7721) and gastric carcinoma (BGC-823 and SGC-7901) cell lines.
Thus, the success of A. tonkinensis use shows TM can maintain its ethnocultural identity while capitalizing on Western scientific
approaches (e.g. chemical isolation of active compounds and their biological validation) to ascertain its efficacy and safety.
