Many client proteins of HSP90, including EGFR, Met, Raf-1, IKK and p53, play important roles in the occurrence and development of tumor. Binding of HSP90 inhibitors triggers the deactivation of HSP90, resulting in client protein degradation, and hence inhibits the tumor growth by blocking multiple targets involved in signaling of tumor proliferation. This review summarizes recent development of small molecule inhibitor
