生物活性

製品説明 Tanespimycin (17-AAG, CP127374, NSC-330507, KOS 953) is a potent HSP90 inhibitor with IC50 of 5 nM in a cell-free assay, having a 100-fold higher binding affinity for HSP90 derived from tumour cells than HSP90 from normal cells. Tanespimycin (17-AAG) induces apoptosis, necrosis, autophagy and mitophagy. Phase 3.
in vitro

Tanespimycin (17-AAG), an analog of geldanamycin, exhibits greater than 100 times higher binding affinity for Hsp90 derived from HER-2-overexpressing cancer cells (BT474, N87, SKOV3 and SKBR3) or BT474 breast carcinoma cells with IC50 values of 5-6 nM. [1] It causes the degradation of HER2, HER3, Akt, and both mutant and wild-type androgen receptor (AR), leading to the RB-dependent G1 growth arrest of prostate cancer cells such as LNCaP, LAPC-4, DU-145, and PC-3 with IC50 values of 25-45 nM. [2] In addition to inducing apoptosis of Ba/F3 cells transformed with wild-type BCR-ABL with an IC50 of 5.2 μM, this compound has the ability to induce apoptosis of cells transformed with T315I and E255K BCR-ABL mutants with IC50 values of 2.3 μM and 1.0 μM, respectively, by inducing the degradation of both wild-type BCR-ABL protein and mutants. [3]

in vivo

Tanespimycin (17-AAG) displays significantly higher binding affinity for Hsp90 from 3T3-src, B16 or CT26 xenografts in nude mice with IC50 values of 8-35 nM as compared with that from the normal tissues with IC50 values of 200-600 nM. [1] Administration of this compound (~50 mg/kg) causes significant decline in AR, HER2, HER3, and Akt expression in a dose-dependent manner with >50% decline at dose of 50 mg/kg, resulting in the dose-dependent inhibition of androgen-dependent (CWR22) and -independent (CWR22R and CWRSA6) prostate cancer xenografts growth by 67%, 80% and 68% at dose of 50 mg/kg, respectively. [2]

特徴 Displays very low toxicity toward normal cells.

プロトコル(参考用のみ)

キナーゼアッセイ Hsp90 binding assays
Purified native Hsp90 protein or cell lysates from HER-2-overexpressing cancer cells (BT474, N87, SKOV3 and SKBR3) or BT474 breast carcinoma cells in lysis buffer (20 mM HEPES, pH 7.3, 1 mM EDTA, 5 mM MgCl2, 100 mM KCl) are incubated with various concentrations of Tanespimycin (17-AAG) for 30 minutes at 4 °C, and then incubated with biotin-GM linked to BioMag streptavidin magnetic beads for 1 hour at 4 °C. Tubes are placed on a magnetic rack, and the unbound supernatant removed. The magnetic beads are washed three times in lysis buffer and heated for 5 minutes at 95 °C in SDS–PAGE sample buffer. Samples are analysed on SDS protein gels, and western blots done using indicated antibodies. Bands in the western blots are quantified using the Bio-rad Fluor-S MultiImager, and the percentage inhibition of binding of Hsp90 to the biotin-GM is calculated. The IC50 reported is the concentration of this compound needed to cause half-maximal inhibition of binding.
細胞アッセイ 細胞株 BT474, SKBR3, N87, SKOV3, MCF7, MDA468, Hs578T, Hs578Bst, A549, HT29, U87, SKMG3, HT1080, RPTEC, NDF, HMVEC, HMEC, HUVEC, and PBMC cells
濃度 Dissolved in DMSO, final concentrations ~10 μM
反応時間 5 days
実験の流れ

Tanespimycin (17-AAG) is added at increasing concentrations and incubated for 5 days after cells are seeded in 96-well plates at 2,000 cells per well in a final culture volume of 100 μL for 24 hours. Viable cell number is determined using the Celltiter 96 AQueous Nonradioactive Cell Proliferation Assay. The value of the background absorbance at 490 nm (A490) of wells not containing cells is subtracted. Percentage of viable cells = (A490 of this compound treated sample/A490 untreated cells) × 100. The IC50 is defined as the concentration that gave rise to 50% viable cell number.
