The Hsp90 inhibitor 17-allylamide-17-demethoxygeldanamycin induces apoptosis and differentiation of Kasumi-1 harboring the Asn822Lys KIT mutation and down-regulates KIT protein level.

Abstract excerpt

Heat shock protein 90 (Hsp90) serves as a chaperone for a number of cell signaling proteins, including many tyrosine and serine/threonine kinases, which are involved in proliferation and/or survival. The benzoquinone ansamycin geldanamycin has been shown to bind to Hsp90 and to specifically inhibit this chaperone's function, resulting in client protein destabilization. 17-Allylamino-17-demethoxygeldanamycin...
