Deguelin
Deguelin, a naturally occurring rotenoid, acts as a chemopreventive agent by blocking multiple pathways like PI3K-Akt, IKK-NF-κB, and MAPK-mTOR-survivin-mediated apoptosis. Deguelin binding to Hsp90 leads to a decreased expression of numerous oncogenic proteins, including MEK1/2, Akt, HIF1α, COX-2, and NF-κB.
