17-AAG
Cat.No. Size
Price
HSP90 inhibitor that displays a 100-fold higher affinity for HSP90derived from tumour cells compared to HSP90 from normal cells.
Because Hsp90 client proteins play important roles in the regulationof the cell cycle, cell growth, cell survival, apoptosis and oncogene-sis, it obstructs the proliferation of cancer cells and shows anti-can- 17-(Allylamino)-17-demethoxygeldanamycin
cer activity in experimental animals. More stable and less toxic ana-logue of geldanamycin (Cat. No. BN0223).
