Abstract:
Hsp90 is an established anti-apoptotic target in cancer therapy [1]. Most of the known small-molecule inhibitors that have shown potent antitumor activity target the Hsp90 N-terminal domain and directly inhibit its ATP-ase activity [2], although displaying important secondary effects. A different approach to Hsp90 inhibition consists of targeting the protein C-terminal domain (CTD) and modulating its chaperone activity through allosteric effects.
An original computational approach [3] and a combination of virtual and experimental screening enabled identification of 1 (Eupomatenoid-2, Fig. 1) as a lead for further development [3].
Chemical approaches to the (glyco)diversification at R4 (Figure 1) will be presented [4] and preliminary results indicate that the compounds obtained so far are CTD ligands and are able to accelerate Hsp90 ATPase activity.
