Biological Activity

Ganetespib (STA-9090) is a potent synthetic small molecule inhibitor of Hsp90 with potential antineoplastic activity. Ganetespib (STA-9090) has shown strong activity in a broad range of preclinical solid and hematologic cancer models, including models highly resistant to treatment.

Cell Experiment
Cell lines NCI-H1975 and HCC827 cell lines
Preparation method Cell viability assays. Cells were grown in 96-well plates based on optimal growth rates determined empirically for each line. Twenty-four hours after plating, cells were treated with the indicated compounds or controls for 72 hours. AlamarBlue (Invitrogen) was added (10% v/v) to the cells, and the plates were incubated for 3 hours and, then, subjected to fluorescence detection. For the comparative viability/ apoptosis assay, NCI-H1975 cells were treated with escalating concentrations of ganetespib for the indicated time periods and subjected to viability analysis via CellTiter Fluor (Promega) and apoptosis via Caspase Glo 3/7 (Promega).
Concentrations 0~10 μM
Incubation time 6, 24, 48, and 72 hours
Animal Experiment
Animal models NCI-H1975 tumor xenograft-implanted SCID mice
Formulation formulated in 10/18 DRD (10% dimethyl sulfoxide, 18% Cremophor RH 40, 3.6% dextrose, 68.4% water)
Dosages 125 mg/kg for 6-72 hours
Administration oral gavage
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
