Mechanism of Action

Targets/IC₅₀/Ki	HSP90 (OSA 8 cells) 4 nM
In vitro	The 50% inhibitory concentrations (IC50) for Ganetespib (STA-9090) against malignant mast cell lines are 10-50 times lower than that for 17-AAG, indicating that triazolone class of HSP90 inhibitors likely exhibits greater potency than geldanamycin based inhibitors. This compound inhibits MG63 cell lines with IC50 of 43 nM. It binds to the ATP-binding domain at the N-terminus of Hsp90 and serves as a potent Hsp90 inhibitor by causing degradation of multiple oncogenic Hsp90 client proteins including HER2/neu, mutated EGFR, Akt, c-Kit, IGF-1R, PDGFRα, Jak1, Jak2, STAT3, STAT5, HIF-1α, CDC2 and c-Met as well as Wilms' tumor 1. At low nanomolar concentrations, it potently arrests cell proliferation and induces apoptosis in a wide variety of human cancer cell lines, including many receptor tyrosine kinase inhibitor- and tanespimycin-resistant cell lines. It exhibits potent cytotoxicity in a range of solid and hematologic tumor cell lines, including those that express mutated kinases that confer resistance to small-molecule tyrosine kinase inhibitors. Its treatment rapidly caused the degradation of known Hsp90 client proteins, exhibits superior potency to the ansamycin inhibitor 17-AAG, and shows sustained activity even with short exposure times. In anohter study, it induces apoptosis of malignant canine mast cell lines. It is active at significantly lower concentrations for C2 and BR canine malignant mast cells with IC50 of 19 and 4 nM, respectively, while 17-AAG inhibits C2 and BR canine malignant mast cells with IC50 of 958 and 44 nM, respectively. Both the expression of WT and mutant Kit are downregulated by 100 nM of this compound after 24 hours in all lines treated including C2 and BMCMCs cells. However, no effects on PI3K or HSP90 expression are observed following treatment with it.
In vivo	Administration of Ganetespib (STA-9090) leads to significant tumor shrinkage in several tumor xenograft models in mice and appears to be less toxic. Furthermore, this compound demonstrated better tumor penetration compared with tanespimycin. It inhibits in vivo tumor growth in both malignant mast cell and OSA xenograft models. Ganetespib significantly inhibits tumor growth when dosed with two repeating cycles of 25 mg/kg/day for 3 days, with a %T/C value of 18. It is well-tolerated, with the vehicle and Ganetespib groups having average bodyweight changes relative to the start of the study of +0.3% and -8.1% on day 17, respectively.

Frequently Asked Questions

Question 1:
Does this inhibitor inhibit both isoforms of HSP90?

Answer:
We don't have the information now and it is not very clear in the literature either. From following two references, it indicates that it might be specific to the alpha form “It binds to the ATP binding site of Hsp90 alpha with a Kd of 110 nM” http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3477583/
