产品描述：
Retaspimycin hydrochloride (also known as IPI-504), a hydroquinone hydrochloride salt derivative of 17-AAG, is a novel, potent and selective inhibitor of heat shock protein 90(Hsp90) that binds to the amino-terminal ATP/ADP-binding site of Hsp90. As a highly water-soluble version of 17-AAG, IPI-504 (solubility > 200 mg/mL) does not need prior dissolution in organic solvents and hence can be delivered in high concentrations. Once in the systemic circulation, IPI-504 is deprotonated and converted into the free base IPI-504 which is subsequently oxidized to 17-AAG. IPI-504 potently inhibits proliferation in several tumor cell lines with 50% inhibition concentration IC50 values ranging from 10-40 nmol/L and has been used for the treatment of gastrointestinal stromal tumors, soft-tissue sarcomas and non-small cell lung cancer.
