Ganetespib 生物活性

描述 HSP90 (heat shock protein 90) is a cellular ubiquitous molecular chaperone responsible for promoting the conformational mutation and stabilization of several client oncoproteins, including Met, B-Raf, p53, Akt, and Kit, function of which is required by tumor cells to maintain appropriate client protein expression necessary for proliferation and survival. Ganetespib is a novel HSP90 inhibitor which is a resorcinol-containing triazole compound unrelated to the first class of HSP90 inhibitors, geldanamycin, 17-AAG and 17-DMAG. As both AKT and KIT are the client protein of HSP90 and are stabilized by it, inhibition of HSP90 by 100nM Ganetespib for 24h caused downregulation of both KIT and AKT only on protein level in BR can C2 cells, as well as a disruption of the association of HSP90 with Kit. Meanwhile, as upregulation of HSP70 is a consequence of HSP90 inhibition, exposure to Ganetespib also caused an induction of HSP70 expression in cells. STA-9090 led to 72-hour growth inhibition of malignant canine mast cell lines C2 and BR with IC50 values of 19nM and 4nM, respectively, much lower than 17-AAG (IC50=948nm (C2) and 44 nm (BR)). Treatment with Ganetespib caused cell apoptosis, shown as increased Annexin V-phycoerythrin [PE] /7-amino-actinomycin D (7-AAD) and increased Sub-G1 level in C2, BR, and BMCMC treated with 100nM Ganetespib for 24 or 48h, cleaved PARP induced by 100 or 1000nM Ganetespib for 24h in BR and C2 cells, and increased caspase3/7 in C2 cells treated with 50 or 75nM Ganetespib for 24h. Intravenous injection with Ganetespib at concentration of 25mg/kg, 3 days on and 2 days off, for 17 days significantly inhibited tumor growth in the C2 xenograft model[1].
作用机制 Ganetespib can bind in the ATP-binding domain at the N-terminus of HSP90. [1]
