Asperulosidic Acid

Asperulosidic Acid (ASPA), a bioactive iridoid glycoside, is extracted from the herbs of Hedyotis diffusa Willd. Asperulosidic Acid (ASPA) has anti-tumor, anti-oxidant, and anti-inflammatory activities. ASPA is related to the inhibition of inflammatory cytokines (TNF-α, IL-6) and mediators via suppression of the NF-κB and mitogen-activated protein kinase (MAPK) signaling pathways.

How to use

In Vitro:

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 .
