A-6880 17-AAG, >99% [17-(Allylamino)-17-demethoxygeldanamycin] [17-(Allylamino)geldanamycin] [Tanespimycin] M.W. 585.69 C31H43N3O8 [75747-14-7] Warning: Toxic. Storage: Store at or below -20 ºC. Solubility: Soluble in DMSO at 150 mg/mL; soluble in ethanol at 5 mg/mL; very poorly soluble in water; maximum solubility in plain water is estimated to be about 20-50 µM; buffers, serum, or other additives may increase or decrease the aqueous solubility. Disposal: A View the MSDS for this product Semi-synthetic derivative of geldanamycin, Cat. No. G-4500, demonstrating greater stability and lower in vivo toxicity than its parent compound. 17-AAG binds specifically to heat shock protein Hsp90 in a manner similar to geldanamycin, but the binding is weaker.
