Ganetespib, an investigational drug candidate, is a selective inhibitor of heat shock protein 90 (Hsp90), a molecular chaperone which controls the folding and activation of a number of client proteins that drive tumor development and progression, added the company.
Several mTOR signaling pathway components such as mTOR, AKT and LKB1 are HSP90 client proteins.
This ATP-driven conformational cycle is regulated by specific co-chaperones, such as HSP70, Hop, immunophilins, cdc37 and p23, that complex with HSP90 and assembles into the HSP90 chaperone machinery, in order to assist the loading and release of client proteins.
These client proteins include a "who's who" list of cancer-relevant targets such as mutated p53, Bcr-Abl, Raf-1, ErbB2 and other kinases, as well as steroid hormone receptors.
