Inhibition of Hsp90 C-terminal function is an advantageous therapeutic paradigm for the treatment of cancer. Currently, the majority of Hsp90 C-terminal inhibitors are derived from novobiocin, a natural product traditionally used as an antibiotic. Assisted by molecular docking studies, a scaffold containing a biphenyl moiety in lieu of the coumarin ring system found in novobiocin was identified for development of new Hsp90 C-terminal inhibitors. Initial structure-activity studies led to derivatives that manifest good antiproliferative activity against two breast cancer cell lines through Hsp90 inhibition. This platform serves as a scaffold upon which new Hsp90 C-terminal inhibitors can be readily assembled for further investigation.

Abstract
Inhibition of Hsp90 C-terminal function is an advantageous therapeutic paradigm for the treatment of cancer. Currently, the majority of Hsp90 C-terminal inhibitors are derived from novobiocin, a natural product traditionally used as an antibiotic. Assisted by molecular docking studies, a scaffold containing a biphenyl moiety in lieu of the coumarin ring system found in novobiocin was identified for development of new Hsp90 C-terminal inhibitors. Initial structure-activity studies led to derivatives that manifest good antiproliferative activity against two breast cancer cell lines through Hsp90 inhibition. This platform serves as a scaffold upon which new Hsp90 C-terminal inhibitors can be readily assembled for further investigation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
