Description: Capillarisin is from Artemisiae capillaris Herba. Capillarisin is a novel blocker of STAT3 activation and thus may have a potential in negative regulation of growth, metastasis, and chemoresistance of tumor cells, it inhibits cancer cell growth of osteosarcoma cells by inducing apoptosis accompanied with G0/G1-phase cell cycle arrest and loss in mitochondrial membrane potential. Capillarisin has anti-inflammatory activity, can inhibit LPS-induced inflammation by blocking TLR4-mediated NF-κB and MAPKs activation in BV2 microglia. Capillarisin possesses promising anti-hyperalgesic and anti-allodynic effects through the inhibition of various inflammatory pain signaling.
