Ganetespib (STA-9090)
Ganetespib (STA-9090; CAS 888216-25-9) is a small-molecule inhibitor targeting heat shock protein 90 (Hsp90). It binds competitively to the ATP-binding pocket located at the N-terminal region of Hsp90, disrupting its chaperone activity and subsequently causing degradation of client proteins involved in tumor growth and survival. Structurally distinct from geldanamycin-derived inhibitors, Ganetespib features a triazolone moiety. Preclinical studies have demonstrated antitumor activity across various cancer cell types, including lung, prostate, colon, breast cancers, melanoma, and leukemia, highlighting its therapeutic potential for cancer research.

| General tips | We do not recommend long-term storage for the solution, please use it up soon. |
| Cell experiment [1]: | |
|
Cell lines |
NCI-H1975 and HCC827 cells |
|
Preparation method |
The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20 °C for several months. |
|
Reaction Conditions |
0.001 ~ 1 μM; 5, 15 or 60 mins or 24 hrs |
|
Applications |
In NCI-H1975 and HCC827 cells, exposure to Ganetespib for only 60 mins resulted in cytotoxicity with IC50 values of 510 and 800 nM, respectively. In NCI-H1975 cells, a 5-minute exposure to Ganetespib still resulted in an IC50 value < 1 μM. |
| Animal experiment [1]: | |
|
Animal models |
SCID mice bearing NCI-H1395 NSCLC xenografts |
|
Dosage form |
150 mg/kg; i.v.; once weekly |
|
Applications |
Ganetespib induced NCI-H1395 tumor regression, with a T/C value of -49%. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
