| RADICICOL Usage And Synthesis |
| Description | Radicicol (12772-57-5) inhibits heat shock protein 90 (HSP90) activity by binding to the ATP-binding pocket.1?In cells HSP90 client proteins such as Raf kinase2, HIF-1α3?and estrogen receptor4?are destabilized and proteolytically degraded. Radicicol inhibits expression of COX-2 without affecting COX-1 expression in LPS-stimulated macrophages (IC50=27 nM).5?Inhibits angiogenesis.6 | | Chemical Properties | Solid | | Uses | Radicicol is a resorcylic acid lactone, produced by several fungal species, that exhibits broad spectrum antifungal and antitumour activity. Radicicol has been the subject of extensive investigation and inhibits protein tyrosine kinase, induces the differentiation of HL-60 cells into macrophages, blocks cell cycle at G1 and G2, suppresses NIH 3T3 cell transformation by diverse oncogenes such as src, ras and mos, and also suppresses the expression of mitogen-inducible cyclooxygenase-2. As a cell differentiation modulator, radicicol has anti-angiogenic activity in vivo, inhibiting the proliferation of plasminogen activator production by vascular endothelial cells. | | Uses | Radicicol is an antitumor antibiotic, which inhibits the Hsp90 molecular chaperone. | | Uses | 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
| | Definition | ChEBI: An antifungal macrolactone antibiotic, obtained from Diheterospora chlamydosporia and Chaetomium chiversii that inhibits protein tyrosine kinase and heat shock protein 90 (Hsp90). | | Biological Activity | Antifungal antibiotic. Inhibits heat shock protein 90 (Hsp90) activity by binding to the ATP-binding pocket, subsequently suppressing cell transformation induced by src, ras and mos. Represses estrogen receptor transcriptional activity and inhibits angiogenesis. | | 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. | | References | 1) Schulte?et al.
