Abstract:


Background. The high sequence and structural homology among the hsp90 paralogs – Hsp90α, Hsp90β, Grp94, and Trap-1 – has made the development of paralog-specific inhibitors a challenging proposition.

Objective. This review surveys the state of developments in structural analysis, compound screening, and structure-based design that have been brought to bear on this problem.

Results. First generation compounds that selectively bind to Hsp90, Grp94, or Trap-1 have been identified.

Conclusion. With the proof of principle firmly established, the prospects for further progress are bright.

Keywords:
