Descripción

General description

Bufalin is a C-24 steroid with an α-pyrone ring positioned at C-17.[1] It is present in the venom glands and skin of toad, Venenum Bufonis.[2] Bufalin is a cardiotonic steroid[3] and is digoxin-like component of Chan Su.[4]

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)[2]
• as a nuclear receptor coactivator 3 (NCOA3) inhibitor in chondrocytes[5]
• to test its anti-metastasis effect in lung cancer cells (NCI-H460) resistant to gefitinib[4]

Biochem/physiol Actions

Bufalin is an anti-metastasis drug[4], which elicits anti-tumor functionality by favoring cell cycle arrest and apoptosis in various cancer types including hepatocellular, bladder and osteosarcoma.[2] It also promotes autophagic cell death and possesses anti-inflammatory properties.[3] Bufalin is a steroid receptor coactivator (SRC) inhibitor.[6]
