Anwendung

Bufalin has been used:

• to test its effect on invasion and activation of nuclear factor kappa- B (NF-κB) cells and tumor necrosis factor-α (TNF-α) stimulated rheumatoid arthritis fibroblast-like synoviocytes (RAFLSs)
• as a nuclear receptor coactivator 3 (NCOA3) inhibitor in chondrocytes
• to test its anti-metastasis effect in lung cancer cells (NCI-H460) resistant to gefitinib

Biochem./physiol. Wirkung

Bufalin is an anti-metastasis drug, which elicits anti-tumor functionality by favoring cell cycle arrest and apoptosis in various cancer types including hepatocellular, bladder and osteosarcoma. It also promotes autophagic cell death and possesses anti-inflammatory properties. Bufalin is a steroid receptor coactivator (SRC) inhibitor.
