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.

Two isoforms of cyclooxygenase (COX) have been identified in eukaryotic cells: a constitutively expressed COX-1 and mitogen-inducible COX-2, which is selectively expressed in response to various inflammatory stimuli. Thus, COX-2 instead of COX-1 is implicated to produce prostanoids mediating inflammatory

The anti-fungal antibiotic, radicicol, produced in the culture broth of Neocosmospora tenuicristata, was found to induce differentiation of HL-60 cells into macrophages from the following evidence: (1) it caused morphological changes into macrophage-like cells, (2) induced NBT (Nitrobluetetrazolium) reduction activity

A novel oxime derivative of radicicol, KF58333, binds to the heat shock protein 90 (Hsp90) and destabilizes its associated signaling molecules. These effects play a critical role in the growth inhibition of tumor cells. To further investigate the effects of
