Asperulosidic Acid (ASPA) (40-160 μg/mL; pre- 1 hour) significantly down-regulates the mRNA levels of TNF-α and IL-6 in LPS-induced RAW 264.7 cells compared with the group treated with LPS alone . Asperulosidic Acid (ASPA) (40-160 μg/mL; pre- 1 hour) decreases IκB-α phosphorylation in a concentration-dependent manner, decreases Erk1/2 phosphorylation at all concentration levels, but there was no effect on p-p38 .
