An Hsp90 inhibitor is a substance that inhibits that activity of the Hsp90 heat shock protein. Since Hsp90 stabilizes a variety of proteins required for survival of cancer cells, these substances may have therapeutic benefit in the treatment of various types of malignancies.[2] Furthermore, a number of Hsp90 inhibitors are currently undergoing clinical trials for a variety of cancers.[3] Hsp90 inhibitors include the natural products geldanamycin, Retaspimycin hydrochloride (IPI 504, a hydroquinone hydrochloride salt derivative of 17-AAG) and radicicol as well as semisynthetic derivatives 17-N-Allylamino-17-demethoxygeldanamycin (17AAG).
