Background: The Hsp90 chaperoning machine is an exciting therapeutic target for cancer treatment. Results: We report that the natural product gedunin inactivates the Hsp90 co-chaperone p23 in vitro and in vivo. The lethal effect of gedunin-p23 complex on cancer cells is amplified by caspase-7-mediated cleavage of the co-chaperone, leading to apoptotic cell death. Conclusions: Gelduin binds directly to p23 leading to inactivation of the Hsp90 machine and selective destabilization of steroid receptors. Significance: Gedunin is a promising compound to develop anti-cancer therapeutics.
