GtoPdb Ligand ID: 9827

Synonyms: 17-AAG (hydrochloride) | 17-Allylamino-17-demethoxygeldanamycin (hydrochloride) | IPI-504 | IPI504
Compound class: Synthetic organic
Comment: 17-Allylamino-17-demethoxygeldanamycin (17-AAG)1 is a semisynthetic inhibitor of the 90 kDa heat shock protein (Hsp90) currently in clinical trials for the treatment of cancer. However, 17-AAG faces challenging formulation issues due to its poor solubility. The synthesis and evaluation of a highly soluble hydroquinone hydrochloride derivative of 17-AAG, 1a (IPI-504) was reported in [1]. A Phase I trial indicated this was well-tolerated with some evidence of antitumor activity, serving as a clinical proof-of-concept that HSP90 inhibition remains promising [2]. Note this ligand entry is an exception to our general rule of salt-stripping because it is clear in this case that the hydorchoride is being used. The parent structure is PubChem CID 11534420.
