产品介绍
Ganetespib (STA-9090) (STA-9090) 是一种热休克蛋白 90 (HSP90) 抑制剂,在多种血液和实体肿瘤细胞系中表现出强效细胞毒性。 Ganetespib (STA-9090) 通过抑制 HIF-1α 在结直肠癌中具有抗血管生成作用;和 STAT3。

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 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20 ℃ 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 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.

产品描述

Ganetespib (also known as STA-9090), 5-[2,4-dihydroxy-5-(1 methylethyl)phenyl]-2,4 dihydro-4-(1-methyl-1Hindol-5 yl)-3H-1,2,4 triazole-3-one, is a potent small-molecule inhibitor of heat shock protein 90 (Hsp90), which binds to the ATP pocket in the N-terminus of Hsp90 resulting in down-regulation of Hsp90 client protein levels. Being structurally unrelated to geldanamycin-derived Hsp90 inhibitors (17-AAG, 17-DMAG, and IPI-504), ganetespib has a unique triazolone-containing chemical structure and stands out other Hsp90 inhibitors in terms of potency, antitumor activity, and safety profile. Results of previous studies indicate that ganetespib exhibits antitumor activity against a broad range of human cancers, including lung cancer, prostate cancer, colon cancer, breast cancer, melanoma and leukemia.
