Selectively inhibits heat shock protein 90 (Hsp90). Binds to the ATP site of Hsp90 (Kd = 1.2 μM) and inhibits its chaperone activity. Consequently inhibits activities of oncogenic kinases (e.g. src, Raf), p53 and steroid receptors. Demonstrates antiproliferative effect on breast cancer stem-like cells.

Preparing Stock Solutions
The following data is based on the product molecular weight 560.64. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.
|Concentration / Solvent Volume / Mass||1 mg||5 mg||10 mg|
|1 mM||1.78 mL||8.92 mL||17.84 mL|
|5 mM||0.36 mL||1.78 mL||3.57 mL|
|10 mM||0.18 mL||0.89 mL||1.78 mL|
|50 mM||0.04 mL||0.18 mL||0.36 mL|
