Gambogic acid protects from endotoxin shock by suppressing pro-inflammatory factors in vivo and in vitro

Objective Gambogic acid (GBA) targeted Heat shock protein 90 (Hsp90) and prohibited TNF-α/NF-κB signaling pathway. It can be inferred that the anti-inflammatory activity of GBA results from inhibiting the cytokine production via NF-κB signaling pathway. We used the RAW264.7 cell line and the endotoxin shock mouse model to confirm the hypothesis that GBA protects mice from endotoxin shock by suppressing cytokine synthesis.
