Description

General description

Bufalin is a C-24 steroid with an α-pyrone ring positioned at C-17. It is present in the venom glands and skin of toad, Venenum Bufonis. Bufalin is a cardiotonic steroid and is digoxin-like component of Chan Su.

Application

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 Actions

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.
