Radicicol (Monorden) is an antifungal antibiotic and a potent inhibitor of heat shock protein 90 (Hsp90), which leads to the degradation of Hsp90 by the proteasome by binding to its ATP-binding pocket. In addition, Radicicol inhibits the growth and proliferation of several tumor cell lines. It also has anti-malarial activity and acts as an inhibitor of adipose- and obesity-related proteins (FTO). Radicicol inhibits iNOS gene expression by blocking the p38 kinase signaling pathway and NF-kB/Rel
