Abstract:
A method for evaluation of molecules to identify those that can act as therapeutic inhibitors of Hsp90 makes use of a fluorescence polarization (FP) assay and a cell based assay, either individually or in combination. The FP assay uses a fluorescently-labeled Hsp90 binding agent and measure the degree of fluorescence polarization relative to the standard. A decrease in the degree of polarization indicates that fluorescently-labeled Hsp90 binding agent has been wholly or partially displaced by a candidate molecule, and identifies the molecule as having activity as an inhibitor of Hsp90. The cell based assay tests for decrease is an Hsp90-dependent activity of normal or tumor cells.
