Gene Information

Application

Radicicol from Diheterospora chlamydosporia has been used as an inhibitor of heat shock protein 90 (Hsp90):
  • to study its effects on lifespan extension and health in Caenorhabditis elegans
  • to study its effects on protein aggregation in yeast
  • to study its effects on xanthone sensitized cancer cells

Biochem/physiol Actions

Radicicol is an antifungal macrolactone antibiotic that is found in Diheterospora chlamydosporia, Chaetomium chiversii, and Monosporium bonorden. It functions as an inhibitor of tyrosine kinase and heat shock protein 90 (Hsp90). Radicicol is involved in the suppression of transformation of various proto-oncogenes such as Ras, Mos, and Src. It also suppresses the activity of mitogen-induced cyclooxygenase-2 (COX-2) and phosphoinositide-dependent kinase 1 (PDK1). Radicicol is involved in arresting the cell cycle at the G1-S phase. It exhibits ant-cancer and anti-angiogenic activity in vivo.

Radicicol, a macrocyclic anti-fungal antibiotic, has the ability to suppress transformation by diverse oncogenes such as Src, Ras and Mos. Despite this useful property, the mechanism by which radicicol exerts its anti-transformation effects is currently unknown. To understand the transformation-suppressing

Intestinal injury is a key feature in sepsis. Inhibitors of heat shock protein 90 (Hsp90) have been shown to exert protective effects in models of inflammation. Herein, we hypothesized that Hsp90 might regulate intestinal inflammation and leakage in abdominal sepsis.
