“ Andrographolide , but not 14-DAP, inhibited partially the IL-2 production induced by CON-A. Andrographolide at doses of 5 and 10 microM reduced the extracellular-signal-regulated protein kinase (ERK1/2) phosphorylation induced by CON-A, whereas 14-DAP only reduced ERK1 and partially the ERK2 phosphorylation.”
